chimney flue repair, obstructed chimney

A chimney is designed to safely and effectively remove dangerous fire byproducts produced within the fireplace. When it becomes clogged, it can’t properly perform this important role. Birds’ nests, tree foliage, trash, and other debris can clog your home chimney, making it dangerous to use. Soot and crumbling bricks are also hazardous; if the chimney’s flue is not kept clean, your home is at risk every time you kindle the fireplace. Your home’s structure and age may also play a part in the overall health of its chimney. Determine if there is a blockage in your chimney, or if it needs flue repair, by looking at it yourself or hiring a professional maintenance company.

Warning Signs of a Blocked Chimney

A blocked chimney may be hard to diagnose on your own but there are some telltale signs to watch for. These warning signs include:

• A smoky smell when burning a fire

• Falling debris inside the hearth

• Water streaks inside the flue

• Excessive soot

• White residue on the flue walls

What can cause a chimney blockage?

There are three main causes of chimney blockages:

• An excessive build-up of soot or creosote (tar)

• Birds, squirrels, or other small animals nesting in the chimney

• The collapse of the internal chimney bricks

Inspecting the Chimney

1. Wear a safety mask or goggles for eye protection. Don a pair of gloves and place a handkerchief over your mouth and nose to keep you from inhaling loose, falling soot. Wear a hard hat to protect your head. Chimneys that have not been periodically cleaned may have a lot of debris.

2. Open the chimney’s maintenance door. Typically, it is located outside the house, but check your home’s blueprints for the exact location. Hold the mirror through the maintenance door, facing upward. With your other hand, shine the flashlight on the mirror. Adjust the angle to allow you to see up into the chimney.

3. Inspect the chimney flue from the outside of the building and again from the inside of the fireplace. Open the damper, and shine the flashlight up the walls with the mirror. See if you can insert a broom handle or long stick through the fireplace opening.

4. Feel the heat. When a clogged fireplace is operating, heat and moisture will back up into the home. When the chimney is unused, during summertime, for example, soot from a wood-burning fireplace or rust debris from the metal hood of a gas fireplace can amass. 

Chimney Flue Repair

Clearing a blocked chimney is a job best left for a professional. They have the tools necessary to reach and remove the debris clogging the flue. How quickly and easily the chimney is cleared will depend on how compact the blockage is. To prevent clogs in the future, an annual chimney cleaning is recommended. Regular cleanings will keep your flue clear while also warning you of any potential problems before they turn into costly chimney flue repairs. Installing a chimney cap onto the flue can also help limit the number of clogs your chimney experiences. Stopping debris from entering the system in the first place, caps can provide a proactive approach to chimney maintenance.

If you suspect a blocked chimney, contact a professional for assistance. We can diagnose and treat common chimney ailments both large and small.

house get smokey, smoke in the house, dangers of smokey fireplace

 

A ѕmоkу fireplace іѕ not only unpleasant; letting your house get smokey can аlѕо be a fire hаzаrd. Whether уоur fireplace is regularly ѕmоkу оr only occasionally ѕо, оnе оr mоrе of these tips mау remedy the situation.

Fоr mоѕt folks, an evening in front of the fіrерlасе саn bе a soothing and relaxing еxреrіеnсе. Thеrе іѕ, however, nothing particularly soothing about unwanted fireplace ѕmоkе рuffѕ that ѕріll into the hоmе while the fіrе is burning. Smоkе that еѕсареѕ through the fireplace opening is the result оf рооr fіrерlасе drafting which саn be саuѕеd bу a number оf factors. Here аrе some оf the mоѕt соmmоn саuѕеѕ and solutions.

 

1. Incorrectly Built Fireplace

Faulty fіrерlасе design may be the reason for your fіrерlасе ѕmоkе problem. Thеrе are critical parts оf a fireplace that muѕt bе built tо ѕресіfіс sizes in rеlаtіоn tо other components. Fluе volume and fіrерlасе opening ѕіzе rаtіоѕ аrе extremely important. Other factors include smoke shelf construction, ѕіzе and ѕhаре of the dаmреr, chimney height in rеlаtіоn tо a реаk of rооf height and ѕо оn. A chimney inspection can help you rule this out.

 

2. Check the Dаmреr

Sоmеtіmеѕ the damper іѕ nоt open аll the way and wіll nоt allow your fіrерlасе tо vent properly. Thе damper is a metal plate that іѕ іnѕіdе уоur chimney and uѕuаllу hаѕ a handle nеаr the bottom that you can move uр and down to open and сlоѕе your damper. It’ѕ nоt unсоmmоn fоr реорlе tо сlоѕе the dаmреr in the summer when іt’ѕ not in uѕе and also during the winter tо keep wаrm аіr frоm escaping the house. Your damper may be closed.

 

3. Chесk Thе Аіr Supply Іn The Room Containing Thе Fireplace

If there іѕn’t еnоugh аіr flowing in the rооm where the fіrерlасе іѕ located, both the fоrmаtіоn оf the draft of аіr that carries smoke uр and out of the chimney and combustion is inhibited. In оrdеr tо figure out if this is the problem and hоw to ѕоlvе іt, уоu just try opening one оr two windows in the rооm when the fіrе is burning. Thе fіrе may stop smoking, and уоu will hаvе tо experiment tо dеtеrmіnе exactly how muсh уоu nееd tо open the windows іf this method does work.

 

4. Exhaust Fans Іn Thе Home

A running kіtсhеn оr bathroom exhaust fаn could bе the cause оf уоur fireplace ѕmоkе. Another culprit mау bе the blower fаn оf a fоrсеd hot аіr heating ѕуѕtеm especially if the furnace rеturn vent іѕ in the ѕаmе room аѕ the fіrерlасе. Thеѕе types оf fаnѕ саn vеrу еаѕіlу сrеаtе a powerful negative pressure hindering the fіrерlасе frоm drafting correctly. If уоu mаkе ѕurе that аll оf these tуреѕ оf fаnѕ аrе off while the fireplace іѕ burning, the ѕmоkе problem mау gо аwау.

 

5. Crеоѕоtе Buildup

Crеоѕоtе is a bурrоduсt оf natural wood that іѕ burnt аt a low temperature. When the creosote solidifies, іt соllесtѕ іnѕіdе the wаllѕ оf уоur chimney. Crеоѕоtе саn start an invisible fire inside the walls or structure of your home, and smoke may be the only clue. When conditions become ѕеvеrе, сrеоѕоtе саn сlоg your chimney making it difficult for аіr tо еѕсаре. Yоur chimney should be сlеаnеd еvеrу уеаr regardless оf whether уоu uѕе іt or nоt, and a chimney sweep should be called immediately if there is unexplained smoke in your home.

 

Dangers оf Smоkе to Homeowners

And although smoke may ѕmеll gооd, іt’ѕ nоt gооd fоr уоu. Inhaling ѕmоkе іѕ dangerous and cause ѕеrіоuѕ health problems. Thе bіggеѕt health threat frоm smoke іѕ frоm fіnе particles, also called fine particulate matter or PM2.5. Thеѕе mісrоѕсоріс particles can gеt into your еуеѕ and respiratory system, where they cause burning еуеѕ, runny nose, and illness, ѕuсh аѕ bronchitis. Fіnе particles саn make asthma ѕуmрtоmѕ worse and trigger asthma attacks. Fіnе particles can аlѕо trigger heart attacks, stroke, irregular heart rhythms, and heart failure, especially іn people who аrе already аt rіѕk fоr these conditions.

Nо matter іf уоur fіrерlасе is already ѕmоkу оr nоt, уоu should mоѕt definitely get your chimney inspected or cleaned (or both) every уеаr tо bе sure уоur chimney and fіrерlасе аrе ѕаfе and сlеаn.

At the Irish Sweep, we pride ourselves on doing the highest quality work. We accomplish this through having excellent training and experience, but also through using top quality materials. One of the truly remarkable materials we use is HeatShield cerfractory flue sealant for resurfacing flues.

According to the Chimney Safety Institute of America, problems such as gaps, cracks and spalling in your chimney’s flue can present serious risks to your home and family, because your chimney can no longer perform its intended function – to safely contain and vent the products of combustion to the outside. It’s because of this that the inner surface of your flue is so important.

HeatSheild is a durable coating applied by experts, like us at the Irish Sweep, to restore safety and efficiency to your chimney’s flue by filling in gaps and cracks. This can salvage a chimney flue that would otherwise have needed removed and rebuilt or retired.

The key to a safe chimney is a flue that properly contains dangerous gases, heat and flames. The rest of your home isn’t a safe place for these elements to be, and your flue is the barrier that protects you. But only until it weakens and develops cracks, spalled clay, and deteriorated mortar. This used to mean the end of life for a flue, but HeatSheild allows us to renew your flue safely.

 

How Does HeatShield Sealant Work?

To start restoring your chimney’s flue by resurfacing the interior, we make a custom foam applicator plug. It’s then placed at the bottom of the flue, attached to a winch on top the chimney. When the applicator it pulled up with the winch, it evenly applies the lining to flue.

First, a “tie coat” material is applied to the flue walls as the plug is pulled upward by the winch. The “tie coat” cleans any remaining dust in your flue and acts as a primer for the HeatShield® Cerfractory® Flue Sealant.

After the tie coat dries, we apply the HeatShield® material to the flue at about ¼” thickness. Our unique application method is known as “slip casting” or “slip cast extrusion”.

We then verify that your new chimney lining has a complete seal and is smoke-tight by using cameras and video scanning your completed repair.

chimney sweep education qualifications certification training

 

You may already know this, but being a chimney sweep takes a lot of education and skill. A worker off the street wouldn’t be ready to understand the details of the work or have the skills to do the job.

Why? Because a chimney sweep doesn’t just clean chimneys, although that alone takes significant safety training. They also detect damage and danger in masonry and can repair or install components of a safe, functional fireplace and chimney system.

 

Chimney Safety Institute of America

The Chimney Safety Institute of America offers certifications in chimney care and related skills. The owner of Irish Sweep and other Irish Sweep employees have various CSIA certifications. These include CSIA Certified Chimney Sweep® and CSIA Certified Dryer Exhaust Technician® credentials. These chimney sweep education certifications are difficult to earn and chimney sweeps must renew regularly.

 

Construction Skills

Masonry work, structural safety, and other construction-type needs often become known during a fireplace and chimney inspection. A good chimney sweep is ready to not only identify these issues, but do upgrades as needed or desired. That’s why it’s important to have a construction background.

Sal of the Irish Sweep has a California State Contractor’s License, a Masonry License, and a specialty license for metal-related work like installation of a wood burning insert. This way you can skip the step of having a chimney specialist explain what you need to a construction specialist. Therefore one highly skilled expert is always best.

 

Continuing Chimney Sweep Education

Some certifications and licenses are required to be a chimney sweep. It’s not required to continually seek out new skills and refresh old ones, like the Irish Sweep does with continuing education. Our awareness of new technology, techniques and  gear keeps your experience with chimney care top quality.

Make no mistake, because the skills and knowledge of a chimney sweep are extensive. If you have any questions or need to schedule chimney or dryer vent servicing, contact the Irish Sweep today.

chimney waterproofing waterproof chimney fireplace inspection

 

While this winter has not been too wet, many are predicting some rain over the next couple months. We don’t anticipate it reaching last year’s levels, but it’s still important that you waterproof your chimney. Water can seep into a chimney and leaks may form. But how does this potentially expensive problem even happen?

What causes chimney leaks?

Chimneys are beautiful, complex structures. The simplistic bricks or stucco columns are filled with a machine of moving parts and instruments to keep you safe and warm. It is also regularly exposed to nature’s elements. Thus, the likelihood of damage occurring and leaks forming is quite possible. However, with all of the nuances of a chimney, it can often be challenging to find the leak. The following are three of the most common sources for chimney leaks.

Chimney Cap

This piece covers the top of the flue. It covers the flue and fireplace so water, animals, and debris do not go in. Should the cap be damaged or missing, this leaves most areas of the fireplace exposed. Thus, a rain shower could cause substantial water damage.

Flashing

Around the chimney and roofline, there is flashing to protect the area against water. Over time, flashing may lose its seal or it could have been improperly installed. Similar to the cap, damaged or missing flashing may dramatically damage your chimney. However, the lack of proper flashing could also harm walls, ceilings, and structures.

Masonry

As you can already tell, water can be very harmful. Bricks are no exception. Water can have a dramatic impact on masonry around chimneys. This can lead to cracks and bricks falling apart. The problem can then get exponentially worse. Damaged bricks absorb greater amounts of water, leading to further harm.

Numerous signs exist to show leaks in chimneys. The easiest way to notice is if you see water dripping in the firebox after a storm. If you hear dripping, then you’ve got issues. At the same time, do not be surprised for there to be a musty smell. Another sign could be damaged bricks around the chimney. If you see this, you should have your chimney inspected.

Prevention

While harm may arise, a homeowner can take proactive measures to prevent damage. First, make sure to do an annual chimney inspection. Second, we recommend sealing your bricks on a regular basis.

Should you have any questions or need your annual inspection done by our certified expert, contact Sal at the Irish Sweep.

Most of us know the beauty of fires through the ones we see in our fireplaces. As we’ve seen wild fires burn throughout California, many of us have been reminded of the real dangers of fire.  The fire within a fireplace gives your warmth and comfort, and the chimney carries the gases from the fireplace and out from its top, providing you with safety in your home.

 

However, many chimneys have underlying problems that can lead to fires inside the chimney. Some of them are visible as they come out the top but many of them are hidden. Sometimes a slow-burning fire is hidden somewhere inside the chimney, without enough fuel to make it grow noticable. Even though they may not be visible, these fires are very hot and can damage the chimney’s infrastructure.

 

chimney fire danger

 Warning Signs

There are generally three signs of a possible chimney fire even when you may not see it. First, you might hear a loud sound. Second, you might see an unusually high amount of thick smoke. Lastly, you will notice a very strong, hot smell.

 

Fuel

A key fuel for these fires is creosote. What is that? It is basically the build-up that covers the inner lining of your chimney. When using a fireplace, certain products are created as a result of fire. Chimneys are designed to take them out through the top. As they go to the top, the cooler temperature hitting these items causes condensation which creates a flaky residue on the inner lining which is highly flammable. This is creosote.

When the quantity of the creosote gets large enough, it can fuel a chimney fire. The main causes for such a build up is a restricted air supply, unseasoned wood, or cooler than normal chimney temperature. These are all preventable with regular chimney inspections and cleaning.

 

Why does it matter?

The high temperature of these chimney fires can damage the interior lining of the chimney, melt mortar, crack tiles, or even destroy prefabricated chimneys. Get your chimney inspected and cleaned each year. If you have questions or want to have your Bay Area home inspected, please contact Sal at the Irish Sweep.

Chimney inspection, fireplace inspection, safety

 

Chimneys keep you warm and can provide a home with a beautiful focal point. However, they can hold hidden dangers and it’s important to regularly check for these signs. Failure to do so can lead to very expensive, dangerous, and preventable conditions.

White Staining

When moisture is seeping into the chimney, white staining may result. While this is actually salt and can be cleaned off easily, identifying the underlying cause needs to be identified to ensure it doesn’t get more serious. A common term for this condition is efflorescence. This can be remedied or prevented through chimney repairs.

Rust

As with most other things, rust is a sign of trouble. It should not arise in the fireplace or damper.  Rust is another sign of moisture issues. Poor sealing or issues with the damper could be the source of this issue. However, these areas may not always be visible so this is why an annual chimney inspection is recommended.

Mortar Joints Deterioration

If you see any mortar joints that are damaged, they should be promptly replaced. These joints could be a source of excess moisture coming in and thereby speed up damage to the chimney. This could be particularly troublesome in very cold conditions where the moisture could freeze and cause much larger cracking within the chimney.

Shaling

A damaged flue lining is a major issue with chimneys. A sign of this issue is small thin shaling or tiles at the bottom of a fireplace, this can look like the ridges on the back of a sea shell. This is a sign that your flue lining may not be in good working condition for your safety. As a result, having this inspected annually is essential for your safety.

Chimney Crown Damage

During the holidays, you may go on your roof to put up lights. This is also a good time to take a look at your chimney crown. If you see it’s damaged, contact us promptly as this can cause moisture to go into your chimney and result in substantial cracking and damage.

Spalling

Spalling is a moisture problem. Should the masonry towards the bottom of a chimney be flaking or popping out, this could be another sign of moisture seeping into the chimney. This is repairable, and it’s important to repair the masonry to protect the chimney.

Damaged Wallpaper

When the wallpaper near a fireplace looks damaged, this can be another sign that you need to have your chimney repaired. When you are in your Bay Area home, periodically check the areas near your chimney.

Most of the above items can be observed by anyone, but there are some that should be done through an annual professional inspection to identify needed chimney repairs. If you have questions or want to have your Bay Area home inspected, please contact Sal at the Irish Sweep.

Chimney masonry repair helps to correct damage and restore the structure to the bricks and mortar of your chimney. While masonry repair is an essential task to keep your chimney safe, many homeowners don’t know how to recognize the signs that a chimney masonry repair is due. Here we look at 4 key signs that you need a chimney masonry repair.

Mortar Worn Away From Between Chimney Bricks

Weather and wear can first affect the softer mortar that fills the space between each brick or stone. Signs of deteriorating mortar joints include mortar crumbling and eroding from the mortar joints or a complete lack of mortar where it’s worn away between the bricks. Mortar repairs, also known as chimney repointing, involve replacing and filling in the joints of brickwork with new mortar. Chimney masonry repair and repointing should be done in warmer months when the mortar can set up correctly, however small repairs can be made using an accelerant mixed in the mortar during winter months.

Cracks In The Masonry And Mortar

Another sign of chimney masonry damage is visible cracks in the bricks or mortar. This can be caused by prolonged weather damage or wear. It’s important to repair chimney cracks rapidly as a cracked chimney can accelerate damage to the remaining bricks and mortar as well as increasing the risk of chimney collapse. Repointing the chimney may help to replace cracked mortar, but larger repairs such as the removal and replacement of bad bricks or a complete or partial tear down may be necessary depending on the damage.

Spalling Bricks

Spalling bricks are caused when moisture and the freeze/thaw cycle disrupt the structure of the bricks and causes them to fail. This causes the brick faces to pop off when water inside the brick freezes in the winter and expands pushing the brick structure outwards. Many chimneys are built with soft style breaks that absorb moisture out more readily and are more prone to spalling. If you notice spalling bricks on your chimney it’s a sign that your chimney needs masonry repair as soon as possible to prevent further deterioration or collapse.

Leaning or Crumbling Chimney

A leaning chimney can either mean that the foundation of the chimney is not right or that there has been movement between the house and the chimney. This can be a difficult problem to diagnose as the foundation of the chimney must be inspected for stability and safety. In many cases this can lead to the need for the chimney to be torn down and rebuilt. A crumbling chimney can be due to cracked bricks or a cracked crown that hasn’t been repaired. If a chimney has already started to significantly crumble or bricks have fallen, it’s essential to have the chimney inspected as soon as possible. The chimney may need to be removed or rebuilt to prevent further damage to your chimney or home.

While many homeowners can ignore a damaged chimney, particularly if it’s not being used, that doesn’t mean that an unstable chimney doesn’t pose a threat to your home. If your chimney shows any signs of needing masonry repair contact your local chimney sweep or chimney specialist as soon as possible to provide a thorough inspection and diagnosis.

Wood burning in fireplaces, though very comforting, have adverse effects on the environment. (Mathew Sumner/San Mateo County Times)FLUE:  Most people say to me, “Will you close the flue once you complete the cleaning process?”  What they are really asking me to do is to close the damper.

So what is the definition of the word flue?  The chimney Safety Institute of America defines this word as, “The passage in a chimney for conveying flue gases to the outside atmosphere.”

And Webster’s Dictionary defines this word as, “A channel or pipe in a chimney for carrying flame and smoke to the outer air.”

The inside of your chimney may contain one or more flues.  It depends upon the number of fireplaces or gas appliances are in the home.
