What Does a Dirty Chimney Look Like?

Safety PSA: How Safe is Your Chimney With All This Rain?

Chimney safety in the rain is no joke.

The weather in California has been exceptionally rainy lately. The state has just experienced our ninth atmospheric river in a three-week succession of major winter storms, leading to flooding, landslides, and hazardous conditions. For residents of the state, it’s essential to be aware of the potential effects of the rain on our homes – particularly our chimneys.

In order to ensure complete safety from potential leaks, erosion, or falling debris, there are certain areas of concern that should be checked and monitored.

How Safe is Your Chimney With All This Rain?

Mortar, the material that binds the bricks of a chimney together, is water soluble. When exposed to moisture from rain, snow, and ice, mortar can become soft or eroded. This can lead to structural instability and damage to a home.

Watch out for these eight areas of concern for chimney safety in the rain:

Soft sheetrock around the chimney. Touch the sheetrock walls on either side of the fireplace fascia and determine if there are indications of moisture. If there is a leak near the ceiling, it is probably a flashing issue.
Moisture inside the firebox. Touch the inside of the firebox and see if the brickwork is moist. If it is, the culprit could be gutter, downspout or flashing issues.
Roof leaks & flashing leaks. Be sure to thoroughly inspect all roofing material for any signs of damage, as leaking or missing roofing material can compromise the stability of the chimney structure.
Heavy rain and hail pounding the chimney. Prolonged exposure to heavy showers can cause erosion over time, weakening the chimney walls.
No flue cap or a loose flue cap. Heavy winds can blow off or loosen a flue cap.
Efflorescence. This is a white powdery residue that can be seen when a chimney dries out after it has become wet.
Falling trees or branches rubbing against the chimney structure. Wet weather will make the tree branches heavier, and with high winds, it can beat a chimney down or cause serious damage. Make sure to pay special attention to any trees in close proximity to bedrooms.
Wind stress on the chimney. High winds can add extra stress to the chimney, particularly if there is an old TV antenna still attached.

By taking the time to inspect these areas of concern, California residents can rest easy knowing that their chimneys are safe and secure during this rainy season. In order to ensure complete safety from potential risks, homeowners should routinely inspect their chimneys for these areas of concern. A certified professional can also provide an inspection and determine if any repairs are necessary.

Preemptive Safety Checks

Taking safety measures now can prevent damage down the line. The Chimney Safety Institute of America outlines what we can do now to protect our homes and chimneys during wet weather.

Check the Gutters & Downspouts

Poorly sloped gutters and gutters that are broken or overflowing can cause water to collect and seep near the chimney. In addition, improperly placed downspouts might act like a funnel for unwanted moisture if not directed away from the structure’s base. All of these conditions have the potential to lead to mysterious pools of water around the chimney. Ensure that all gutter and downspout systems are in good working order. They should move water away from the chimney structure, not directly onto it.

Inspect The Roof

A properly installed and well-maintained roof is the first line of defense against water seepage. Inspect the flashing around the chimney, along with any sealants used in the installation. Also look for signs of cracking or wear that might indicate a need for repair.

Check the Base of the Chimney

The base of the chimney should be sealed and able to withstand moisture. Have a professional inspect any concrete or masonry blocks that have become cracked or weathered in order to repair them before they become damaged by water.

Post-Rain Safety Tips

Have a professional inspect the chimney after a heavy storm. This is especially important if any of the warning signs mentioned above have appeared.
Inspect the interior walls for water damage, corrosion, and staining.
Schedule an annual sweeping to ensure that moisture isn’t collecting inside the chimney liner or flue.
Check for any signs of mold or mildew.
Have a professional inspect the chimney if it emits any strange odors.

By doing these simple maintenance checks, homeowners can confidently protect their homes and chimneys from potential risks associated with wet weather.

Creosote Self-Cleaning Logs: Helpful or Harmful?

Are creosote self-cleaning logs the answer to fireplace woes? Maybe it’s an easy way to keep that chimney clean and make those cold winter mornings bearable, or maybe it should be avoided with caution. Before stocking up on logs, let’s separate fact from fiction and discuss what these self-cleaning logs are all about—the good, the bad, and if they’re actually helpful or harmful for chimneys.

How Do Creosote Self-Cleaning Logs Work?

The Need-to-Know About Creosote

First, let’s define creosote. This tarry, black substance sticks to the walls of a chimney as a result of burning wood and can be flammable if it builds up in large enough quantities.

Fuels like hardwood, softwood, and compressed logs release various by-products, such as smoke, water vapor, hydrocarbons, and tar fog while burning in a fireplace. When these substances escape through the chimney (which is cooler), they condense on the inner surface of the chimney and create a sticky residue called combustible creosote and tar. To keep a chimney clean, it’s important to have it inspected annually and have any creosote removed by a professional.

According to the National Fire Protection Association, the leading factor contributing to home heating fires (30%) was having a dirty chimney (i.e., creosote buildup). These fires are completely preventable with regular chimney maintenance!

When Is Creosote Buildup Serious?

Creosote buildup can be a serious fire hazard, so it’s important to take steps to prevent and remove it. There are different stages of creosote buildup, and if left unchecked, it can eventually form a layer of glazed creosote, which is the most combustible type.

Stage I Creosote: This is the most common type of creosote and is characterized by a flaky or powdery layer. It can be safely removed with regular chimney cleaning but should not be ignored.

Stage II Creosote: This type of creosote is darker and shinier than stage I and has a tar-like consistency. If this type of creosote is present, it should be professionally removed to avoid any fire hazards.

Stage III Creosote: This is the most dangerous type of creosote and is usually jet-black in color and glossy or shiny. It’s highly combustible and should be removed immediately by a trained professional.

About Creosote Self-Cleaning Logs

Now, let’s talk about creosote self-cleaning logs. These logs burn at an increased temperature compared to traditional wood-burning logs, which can help break down built-up creosote in the chimney walls. Many brands of self-cleaning logs are designed to be used on an as-needed basis, meaning they should only be burned as needed once or twice a year. Burning these logs more often may lead to damage to the chimney or even fire hazards.

Creosote self-cleaning logs are made from a variety of natural ingredients and chemical accelerants, which helps raise the burn temperature. Some logs contain sawdust mixed with wax or other substances with a higher burning point than traditional wood-burning logs. Other types may contain paraffin wax, sodium nitrate, or charcoal briquettes. The idea is that by burning these logs at higher temperatures, creosote within a chimney will be burned off sooner or avoided altogether. These logs are also designed to release additional chemicals that supposedly enhance the cleaning process.

Are Creosote Self-Cleaning Logs Helpful or Harmful?

Now comes the million-dollar question: Are these logs safe and effective? Unfortunately, there isn’t a clear answer as to whether or not these logs are helpful or harmful for chimneys. Though some chimney sweeps may recommend them, there’s no scientific evidence that these logs actually clean creosote out of a chimney.

In fact, some experts caution against using these logs as they can cause damage to the chimney or even fire hazards if not used correctly. The higher burning temperature released from creosote self-cleaning logs can actually cause further creosote buildup if used improperly or too often.

In short, it’s best to consult a professional chimney sweep before using these logs to ensure they are safe and effective for a fireplace and chimney. Overall, regular maintenance and inspections are key to avoiding the dangers of creosote buildup.

Takeaways About Self-Cleaning Logs:

Self-cleaning logs should never be used as the primary source of heat during cold winter months.
These logs do not replace the need for annual chimney inspections and cleanings.
Burning these logs can increase the risk of a chimney fire if used too often or in combination with other fuels such as coal or wood pellets.
The use of these logs can lead to an accumulation of ash in the flue, which can cause dangerous blockages and reduce ventilation.
Self-cleaning logs may also emit hazardous fumes and gases, so it’s important to make sure the room is properly ventilated when burning them.
Some brands of self-cleaning logs may contain additives that are potentially hazardous to our health and the environment.

The Bottom Line

Creosote self-cleaning logs can be helpful in reducing creosote buildup, but they should be used in moderation and only as a supplement to regular chimney inspections and cleanings. It’s also important to read the directions carefully before using self-cleaning logs and make sure the room is properly ventilated during burning.

Ultimately, the decision to use these logs or not should be based on personal preference and needs. However, it’s important to remember that these are just one tool for helping keep a chimney clean and safe—annual inspections and cleanings by a certified professional should never be replaced or neglected.

Better Ways to Remove Creosote

The best way to remove built-up creosote from a chimney is still a professional cleaning. Certified technicians have the tools and experience necessary to safely remove creosote and other debris from a chimney while also inspecting it for any potential problems or hazards. Additionally, regular inspections can help ensure that the firebox and flue are in good condition and that the chimney is properly ventilated.

Preventing Creosote Buildup

In addition to regular inspections and cleanings, there are a few other ways to prevent creosote buildup in a chimney.

Burning only dry, seasoned wood is one of the best ways to reduce creosote formation, as unseasoned or green wood can create more smoke and cause it to stick to the walls of the chimney.
Burning smaller fires can help prevent creosote buildup as well.
Finally, keeping the damper open and fully extended when lighting a fire can also help reduce smoke and the resulting creosote formation.

Preventing Chimney Fires

Chimney fires are a serious threat and can be caused by built-up creosote, but there are also other factors that increase the risk.

Make sure never to burn any type of flammable materials in the fireplace, such as cardboard boxes or wrapping paper.
Avoid burning items like pine cones or Christmas trees that can cause sparks to fly up the chimney and ignite any built-up creosote or debris.
Finally, keep the fireplace clean and clear of any debris or combustible materials that could catch fire.
Taking these precautions can help reduce the risk of a chimney fire and keep the home safe.

As professional chimney sweeps, we don’t mess around with creosote buildup and take extra care to make sure our chimneys are safe and up to code. If in need of an inspection or cleaning, give us a call today! We’re always happy to help.

In conclusion, creosote self-cleaning logs can be helpful in reducing the build-up of creosote, but they should not be used as a replacement for professional cleaning. For best results, all chimneys should be inspected annually and cleaned when necessary by certified technicians.

What Is the Best Wood to Burn in a Fireplace?

Ever wondered why some fires burn hotter and longer than others? A crackling fire is one of the simplest pleasures of winter, but not all firewood burns the same. Choosing the best wood to burn in your fireplace can make all the difference in heat output, efficiency, and safety. The right firewood burns cleaner, produces more heat, and reduces creosote buildup in your chimney.

This guide will walk you through everything you need to know about selecting, seasoning, and burning the best firewood for a cozy and safe home.

Why Choosing the Right Firewood Matters

Selecting the right firewood isn’t just about warmth—it also affects indoor air quality, maintenance, and safety. Poor firewood choices can lead to excess smoke, inefficient burning, and increased creosote buildup, which can become a fire hazard.

Key Benefits of Using the Right Firewood:

Higher heat output – Quality wood burns hotter, keeping your home warmer.
Less creosote buildup – Dry, seasoned wood minimizes the risk of chimney fires.
Cleaner burning – The right wood produces less smoke and fewer emissions.
Longer burn times – Hardwood logs burn longer, reducing the need for frequent refueling.

Hardwood vs. Softwood: What’s the Difference?

Firewood falls into two main categories: hardwood and softwood. Understanding their differences will help you make the best choice for your fireplace.

Hardwood:

Comes from deciduous trees (oak, maple, ash, hickory, birch).
Denser wood that burns longer and hotter.
Produces less smoke and creosote.
Ideal for indoor fireplaces and wood stoves.

Softwood:

Comes from coniferous trees (pine, fir, spruce, cedar).
Burns faster and produces more smoke.
Higher resin content, leading to more creosote buildup.
Best used for kindling or outdoor fires.

Best Choice for Fireplaces: Hardwoods are the superior option due to their efficiency, long burn time, and minimal creosote production.

Best Wood to Burn in a Fireplace

Not all hardwoods are equal when it comes to burning. Here are the top firewood choices based on heat output and burn quality:

Wood Type	Burn Time	Heat Output	Pros	Cons
Oak	Long-lasting	High	Burns slowly with steady heat, minimal smoke	Requires up to two years of seasoning
Hickory	Long-lasting	Very High	One of the hottest-burning woods, great for cold winters	Hard to split and needs extended drying time
Maple	Moderate to long	Medium to High	Readily available and burns cleanly	Harder to split than some other hardwoods
Ash	Long	High	Dries faster than oak, burns cleanly	Slightly less heat than hickory or oak
Cherry	Moderate	Medium	Pleasant aroma, minimal smoke	Not as hot-burning as oak or hickory

How to Properly Season and Store Firewood

Firewood needs to be seasoned (dried) to reduce moisture content before burning. Burning wet or “green” wood produces excess smoke, low heat, and increased creosote buildup.

Signs of Properly Seasoned Firewood:

Cracks on the ends.
Lighter weight compared to green wood.
Produces a hollow sound when knocked together.
Moisture content below 20% (use a moisture meter to check).

Proper Storage Tips:

Stack off the ground – Use pallets or a firewood rack.
Allow airflow – Stack wood loosely in a crisscross pattern.
Cover the top – Protect from rain and snow but leave sides open for ventilation.
Store for at least 6-12 months – Oak and hickory may require longer.

Tips for a Safe and Efficient Fireplace Fire

Start with dry kindling – Use small softwood pieces or fire starters.
Build a top-down fire – Place large logs at the bottom, medium logs above, and kindling at the top.
Ensure proper airflow – Keep the damper open to maintain a strong flame.
Clean your chimney regularly – Hire professionals like The Irish Sweep to remove creosote buildup.
Never burn painted or treated wood – These release harmful toxins.

The 13 Things Professional Chimney Sweeps Want You To Know

Think you can clean your own chimney? Think again! Professional chimney sweeps have seen it all, and we’ve collected that wisdom and put it in a neat list format for our latest article. Here are 13 things professional chimney sweeps wish you knew – and why you should always hire us for the job!

Creosote buildup is dangerous!!!

Creosote is a substance that forms when anything is burned, especially wood and manufactured logs. Creosote will build up in the chimney without you realizing it. If the creosote isn’t removed, it will become a fire hazard. That’s why it’s so important to have the chimney cleaned regularly by a professional.

We have specialized tools

Professional chimney sweeps have brushes and vacuums designed specifically for cleaning out chimneys. Specialized equipment helps ensure that all the soot and ash are removed – something that’s crucial to preventing fires.

Chimney sweeping is a vital part of home maintenance

Many people think of chimney sweeping as something that’s only done occasionally, but the truth is that it’s an essential part of regular home maintenance. Sweeping the chimney helps prevent a build-up of creosote, which can cause fires. The chimney should be inspected and cleaned at least once a year – more often if it’s used frequently.

It’s more complicated than Mary Poppins makes it look!

Chimney sweeping may look easy in movies like Mary Poppins, but the truth is that it’s a tough job. It requires a lot of physical strength and stamina, as well as experience, knowledge, and specialized tools. That’s why it’s always best to leave it to the trained professionals.

We know how to spot problems

One of the advantages of hiring a professional chimney sweep is that we know how to spot problems. We can identify issues such as cracks in the flue or blockages that could cause fires. This means we can fix the problem before it becomes a dangerous hazard.

A dirty chimney can cause respiratory problems for our families

Soot and ash aren’t good for our lungs, and a dirty chimney can cause respiratory problems for our families. This is especially true if anyone in the family suffers from asthma or allergies. A professional chimney sweep will ensure that the chimney is clean and safe!

A properly functioning chimney will help keep our home warm and save money on heating costs

If the chimney is blocked or has cracks, it won’t draw air correctly. There will always be air turnover, as this is how fire is fueled. The home can be harder to heat if the fireplace and chimney are functioning correctly, which then costs more money in heating bills. A professional chimney sweep can help ensure that the chimney is working properly, saving money in the long run.

We can save time and reduce hassle

Cleaning a chimney is a time-consuming job that most people simply don’t have the time for. Hiring a professional chimney sweep will save hassle and ensure that the job is done right.

Wood-burning stoves need to be inspected and cleaned regularly, too!

It’s essential to have a wood-burning stove or insert inspected and cleaned regularly. This is because the chimney, chimney connector, and liner can become blocked with soot, which can be a fire hazard. A professional chimney sweep can clean the wood-burning stove or insert and make sure it’s safe to use.

Chimney sweeps can help with other types of fireplace maintenance

Chimney sweeps can also help with different kinds of fireplace maintenance, such as relining the chimney or repairing damage. Have peace of mind that the fireplace is safe to use all year round!

Call a chimney sweep before there’s a problem

Be proactive – the damage has already happened by the time a problem is noticed. It’s never too late to call a professional; it may just cost more. By then, the damage may have already been done – and it could be dangerous. That’s why it’s crucial to have the chimney cleaned regularly, even if there’s no apparent problem.

12. We carry insurance – just in case

Double-check that the professional chimney sweep carries insurance just in case something goes wrong. It’s good to be protected in the event of an accident!

Are Your Indoor Dryer Vents Causing an Increase in Your Energy Bill?

Think your energy bill is high enough as it is? Your indoor dryer vents could be increasing your bills without you even realizing it. Materials like lint, hair, and debris clog your dryer ducts and strain the appliance, making it work much harder than it needs to. Not only is this bad for your energy bill, but it’s also a fire hazard!

Here’s how to tell if your indoor dryer vents are increasing your energy bill – and what to do about it!

Is My Indoor Dryer Vent Wasting Energy?

Is it Clogged with Debris?

It’s amazing what ends up getting down those indoor dryer vents. Anything from loose change, bobby pins, safety pins, credit cards, lint, pet hair, human hair, tissues forgotten in pockets… The list goes on and on. When your indoor dryer vent is clogged with debris, it puts a strain on the appliance and makes it work much harder than it needs to. It also causes unnecessary wear and tear, which can lead to costly repairs down the line.

Does it Have Long or Winding Ducting?

Anything that gets stuck and clogs up the indoor dryer vents makes it work harder and use more energy. If you have long or winding ducting, it’s even more important to keep an eye on clogs. That’s because the longer the duct, the greater the chance that something will get stuck and cause a blockage. Whether it’s short ducting just through to the outside wall, long from upstairs, in apartment blocks, or with elbows in the ducting to go around corners – all of these impact the ability of the dryer to function properly.

Is Your Dryer Not Doing its Job?

One symptom of a dryer vent that’s wasting energy is clothes that come out hot or damp after a cycle. If your clothes are taking longer to dry than they used to, or if they’re coming out damp or smelling burnt, it’s a sign that your dryer is working harder than it needs to – and wasting energy in the process.

Have You Noticed a Musty Odor?

A musty smell coming from your dryer is another sign that it’s not venting properly. When indoor dryer vents aren’t working correctly, moisture can build up and cause mold or mildew to grow. This is both hazardous to your health and damaging to your clothes.

Is the Laundry Room Hot and Steamy?

If your laundry room feels hotter and more humid than usual, that’s another sign that your indoor dryer vent isn’t working properly. All of that hot air has to go somewhere! When vents are blocked, heat and moisture can build up in the laundry room.

Has it Been a Year Since Your Last Cleaning?

Even if you can’t see or smell any problems, it’s a good idea to have your indoor dryer vents cleaned at least once a year. Over time, lint and other debris build up no matter how careful you are. A professional cleaning will remove all of the hidden buildup and help your dryer run more efficiently.

Why Does Dryer Efficiency Matter?

Wasting energy not only drives up your energy bills, but it’s also bad for the environment. Indoor dryer vents that aren’t functioning properly can waste a lot of energy, which is why it’s important to keep an eye on them. Not only will you save money, but you’ll be doing your part to protect the planet. You’ll also enjoy:

Decreased risk of fire: Indoor dryer vents that are clogged with lint and debris are fire hazards. By keeping your vents clean, you’ll decrease the risk of a fire starting in your home.
Improved appliance lifespan: When your indoor dryer vent is functioning properly, it puts less strain on the appliance. This means it will last longer before needing to be replaced.
Improved air quality in the home: The air inside your dryer is a major source of harmful air pollutants and allergens. A clean vent will improve the air quality in your home and discourage mold growth, making it a healthier place to live.
Better appliance functionality: When your indoor dryer vent is clean, it will work more efficiently and effectively. Your clothes will dry faster, and you won’t have to run the appliance as often!

How to Maximize Indoor Dryer Vents for Energy Efficiency

If you’re worried that your indoor dryer vent is wasting energy, there are some things you can do to help fix the problem.

Don’t Let Lint Build Up

One of the best ways to prevent indoor dryer vent problems is to make sure lint doesn’t have a chance to build up in the first place. After each load of laundry, take a few minutes to clean out the lint trap. This will help reduce the amount of lint that gets down into the ducts and clogs them up.

Check for Clogs Regularly

Even if you’re diligent about cleaning the lint trap, it’s still a good idea to check for clogs on a regular basis. Once a month or so, disconnect the indoor dryer vent from the appliance and use a vacuum with a long attachment to clean out any lint or debris that may have gotten past the trap.

Opt for Professional Cleanings

If you really want to maximize the energy efficiency of your indoor dryer vents, you can opt for professional cleanings. This is especially a good idea if you have long or complex ducting that’s difficult to clean on your own. A professional will be able to reach all the nooks and crannies and remove any build-up, so your dryer can run at peak efficiency.

By following these tips, you can help ensure that your indoor dryer vent is running as efficiently as possible – and saving you money on your energy bill in the process!

The seasons are changing, the cold, wet weather is almost upon us. Now is the time to be proactive with getting the dryer vent cleaned out and, if necessary, the dryer serviced.

The Irish Sweep specialists can get deep into your vent system where most household cleaning methods can’t reach, so you can enjoy a safer and more effective system for years to come. Our top priority is safety, and we customize our services with our client’s best interests at heart.

Chimney Masonry Repair 101 (Basics You Need to Know)

Repairs and maintenance are unavoidable in any part of a home. Just like most structures and appliances, this is also true for chimneys. All fireplaces and chimneys will eventually have problems that necessitate repair or maintenance – it’s an inevitability regardless of age or design.

This blog post will discuss the basics of chimney masonry repair. We’ll cover the different materials that can make up a chimney, common problems with chimneys and how to repair them, and tips for keeping your chimney in good shape year-round!

Why Is Chimney Maintenance Important?

The most common causes of home fires include smoking, cooking, and electrical malfunction. While you can control some more frequent home fire causes, others like electrical malfunctions or faulty masonry chimneys are harder to pin down. Did you know:

More than 61 chimney fires occur every day in the United States
The #1 most common cause of chimney fires is a failure to have them regularly cleaned
The 2nd most common cause of chimney fires is burning unseasoned wet wood
Chimney fires cost homeowners an estimated $125 million in damages every year

Chimney fires are preventable. While it’s impossible to anticipate every disaster, you can take steps to minimize the risk of a chimney fire in your home.

Masonry Chimneys 101

Bricks and mortar, concrete, block, stone, flue tile, cast iron, and steel are just a few of the materials used to construct a masonry chimney. If not correctly installed or maintained, any of these materials can be vulnerable to rainwater and environmental elements. Mortar, the substance that bonds together the masonry components in their chimney, is water soluble. This is why keeping your structures dry and preventing water intrusion is so important!

While properly built and well-constructed masonry chimneys can endure a long time (consider the Roman Arches, which still exist today), this does not imply that all masonry chimneys are created equal. Inferior materials or craftsmanship can lead to chimney deterioration and, in some cases, a structurally unsound chimney. In cases like these, you will need reliable chimney masonry repair services.

Common Chimney Masonry Repair Problems

Don’t be intimidated by chimney masonry repair! The most common problems with masonry chimneys include:

Chimney crown cracks
Water penetration
Leaning chimney
Damaged or missing mortar joints
Chimney deterioration

These problems can be caused by various factors, including water damage, excessive heat exposure, poor construction, and more. If left unaddressed, these problems can lead to even more significant issues like chimney fires or collapse.

Chimney Crown Cracks

A chimney crown is the cement cap that sits atop the chimney. Its job is to prevent moisture from seeping into the chimney’s masonry where it is most vulnerable to the elements: at the top.

However, chimney crowns can crack over time due to age, weathering, or settling. Cracks in the chimney crown can allow water to seep into the chimney structure, leading to further deterioration. In climates reaching freezing temperatures, water entering the chimney can freeze and expand, causing the crown to crack even further.

What to Do About Crown Cracks?

The best way to repair chimney crown cracks is to have a professional chimney sweep or mason take a look at them. They will be able to determine the extent of the damage and recommend the best course of action. In some cases, the chimney crown may need to be rebuilt entirely.

Water Penetration

Another common problem with masonry chimneys is water penetration. Water can enter the chimney through cracks in the chimney crown, flue, or mortar joints. Once inside, the water can cause problems like rusting metal components and deteriorating masonry.

When water mixes with creosote – a tarlike substance that builds up on the chimney walls – it creates a corrosive acid that eats away at the chimney’s masonry. This can lead to even more severe problems like chimney collapse.

What to Do About Water Penetration?

Keep a regular chimney checkup schedule and ensure there is no place for water to seep into any section of the chimney or fireplace. If you find water leaks, have a professional chimney sweep or mason look at it as soon as possible. They will be able to determine the source of the leak and make recommendations for repairs.

Leaning Chimney

A leaning chimney is a cause for concern. It can be caused by many factors, including foundation settling, water damage, or poor construction. A leaning chimney can put your entire home at risk of chimney collapse.

What to Do About a Leaning Chimney?

If your chimney is leaning, it is structurally unsafe. It’s essential to have a professional chimney sweep or mason look at it as soon as possible. They will be able to determine the cause of the problem and make recommendations for repairs. In some cases, the chimney may need to be rebuilt entirely.

Damaged or Missing Mortar Joints

Mortar joints are the spaces between bricks, stones or clay flue liners in a masonry chimney. They are filled with mortar, which acts as glue to hold the chimney together. Over time, the mortar can become cracked, crumbled, or missing. This can leave the chimney vulnerable to water damage and collapse.

What to Do About Damaged or Missing Mortar Joints?

One of the most common repairs needed for a chimney is mortar replacement, also called tuckpointing. Tuckpointing joints back in are usually not complicated. Occasionally, extensive damage demands more comprehensive repairs, which may include reconstructing part or all of the chimney, but tuckpointing is a satisfactory repair for minor damages. As for all major repairs, it’s best to have a licensed chimney professional take a look.

Chimney Deterioration

Like any other structure, a chimney will eventually show wear and tear. Flue liner and smoke chamber damage, loosened brickwork, water damage, and mold are all common symptoms of chimney deterioration.

What to Do About Chimney Deterioration?

The best way to prevent chimney deterioration is to opt for an annual inspection by a certified chimney professional. Their specialized tools and knowledge will help them spot any potential problems so they can be fixed before they cause further damage. You can avoid serious problems down the road by being proactive and getting annual chimney inspections.

Easy Chimney Health Tips

Maintaining a chimney is much preferable to fixing a broken chimney. Here are a few easy tips to help you keep your chimney in good shape:

Have your chimney inspected and cleaned yearly by a certified chimney professional.
Repair any cracks or damage as soon as possible.
Make sure there is no place for water to seep into any section of the chimney.
Keep trees and bushes trimmed away from the chimney.
