What Does a Dirty Chimney Look Like?

How Rain Affects a Chimney Without Cap

April showers bring May flowers, right? Well, they can also bring leaky chimneys! If you have chimney without cap, you’re in for a wet time. You’ll start seeing symptoms of leaks during spring and summer, and even chimneys that’ve never had problems before can leak.

YOUR CHIMNEY WITHOUT CAP

Chimneys are complex structures and are always exposed to the weather. They aren’t designed to go with chimney without cap, but not everyone knows this. Because chimneys are always exposed, rain water, leaves, feathers, and all sorts of things can fall into them and build up or cause damage.

The entrance of rain into your chimney may not sound very dramatic to you. But when the masonry and other components in your chimney degrade and lose stability, or lose fire proofness, it becomes dramatic. Wetness can cause spalling and crumbling brickwork, and things like leaves that fall into your chimney are a fire hazard.

WHY GET A CHIMNEY CAP?

The top reason is to prevent damage to your home. To prevent water coming in, part of a chimney cap acts like an umbrella, and a screen section prevents the debris from falling in or sparks from floating out.

Don’t worry about a chimney cap affecting your draft. If your chimney cap has sufficient clearance and you keep it clean, it will either not affect your chimney draft or improve it. When wind blows, the convex shape of the cap creates a slight vacuum at the top of the flue so your chimney should draw better with the cap in place. Some chimney caps are even specifically designed to improve chimney draft!

IF YOU SEE WATER COMING IN, IT COULD ALSO BE DUE TO: FLASHING

If your chimney flashing starts to wear down, water can get in. Flashing is a tight strip inside your chimney that seals the seam between your roof and chimney to prevent water coming in. If the flashing is damaged or loses its seal due to age or wear and tear, water will get through the gaps. This can in turn water damage to the roof, chimney, ceilings and walls. Metal flashings are preferred over mastic flashings.

INCORRECT CHIMNEY CAP

Water can get in if the chimney cap doesn’t fit well. Chimney without cap that fits, the fireplace and flue are completely exposed to water from the rain. An ill-fitting cap is barely better than no cap at all.

MASONRY DAMAGE

Because your chimney is directly exposed to rain, the masonry components will deteriorate over time. Water can cause bricks to spall and crack (letting in water), in addition to making your chimney look unkempt.

You may know your chimney is leaking because you see visible water in the flue or fireplace. But because of the complexity and size of many chimney systems, leaks can easily go undetected for a while. You might not even know there’s water damage until significant damage has already been done.

To prevent chimney leaks, it’s best if you call in a professional for annual Irish Sweep chimney sweepings and inspections. We’ll be able to detect any damage so that you can get it fixed before the chimney starts to leak!

Earthquakes And Chimney: Why Repair And Maintenance Is Essential

The devastation of the recent Earthquake in Mexico is a reminder that the same could, and has, happened in California. Long term California residents will remember several damaging and in some cases lethal earthquakes in their lifetime. Earthquake preparedness experts warn that the likelihood California will experience another serious quake in the next 20 years is very high, with the San Francisco Bay Area expected to be the worst hit.

And yet despite these risks, homeowners neglect the one thing that could prevent the most common form of damage in an earthquake: chimney repair.

Chimney Collapse is The Most Common Form of Earthquake Damage

Historically, chimney collapse is the most common form of damage due to earthquakes across the country. And yet chimney repair and reinforcement is the most commonly ignored effort for earthquake preparation.

Chimney masonry repair or even chimney removal is likely to slip your mind if you no longer use your masonry chimney. But simply leaving your chimney standing with no reinforcement or maintenance is a recipe for earthquake disaster.

Even with low-level ground shaking, chimneys start to fail and bricks fall. This is particularly common in masonry chimneys built before 1980 where the mortar may be already worn down and the structure of the chimney is brittle. But even in younger chimneys the mortar can become weak or cracked due to weather and time, leaving masonry chimneys vulnerable to collapse even with a small earthquake.

Collapsing Chimneys Extremely Hazardous

Structural engineers say that masonry chimneys are usually the first thing to go in a quake of any size, and can rapidly cause damage to surrounding buildings, cars, and people. At least 15,000 brick chimneys were damaged in Los Angeles during the 1994 Northridge earthquake, while in Napa, about half of the residential buildings damaged were due to brick chimneys.

Several deaths and injuries have also been caused by falling chimney bricks in the last significant California earthquakes, many of them involving children. When chimneys start to collapse, even during a relatively minor earthquake, bricks become deadly projectiles capable of causing severe damage.

Earthquake Proof Chimneys To Prevent Chimney Damage

When quake-proofing your home, don’t overlook your chimney. If you have a masonry chimney in your home, it is essential you call a chimney professional for an inspection and analysis of the chimney strength. This is very difficult to assess with an untrained eye. But if you can see visible cracks or gaps in the mortar of your chimney, it’s a clear sign your chimney needs urgent repair.

Masonry chimneys can be repaired and retrofitted to increase their strength, which prevents the likelihood of collapse in the event of an earthquake. Chimney repointing can help to replace masonry chimney mortar, but may not be enough earthquake preparedness on It’s own to reinforce a chimney. Retrofitting is the minimum step you should take to keep your home and your family safe from chimney damage during an earthquake. You can also discuss other options, such as chimney removal or replacement, after an inspection and consultation with a chimney professional.

Ensuring your chimney is safe and secure is essential for earthquake preparation, and shouldn’t be put off any longer. Call your local chimney professional today to book an inspection and discuss the best solution to keep your chimney earthquake safe.

5 Signs You Might Need Chimney Removal

Chimney removal is often advised, but many homeowners put it off, not considering the benefits of full chimney removal. Many homes have been built with fireplaces for heating, and they also have chimneys. As time has provided the innovation of other, more efficient heating methods, fireplaces and chimneys may not be used so often. Here we look at 5 reasons that you should consider having your chimney removed.

Chimney Removal Aides Home Heating/Cooling

If you are no longer using your fireplace for home heating, it’s possible your chimney is only working against your home heating and cooling efforts. Chimneys left in place may compromise insulation and allow drafts which hamper energy efficient home heating and cooling. Removing a chimney can help to create a more comfortable home environment while reducing energy usage and costs for heating and cooling.

You Want to Reduce Risk of Earthquake Damage

Chimneys are often the first structures to fall in an earthquake. If you haven’t used your chimney for years, it’s likely the chimney is worn out and damaged and at even higher risk of earthquake damage. Even a slight tremor can turn a masonry chimney into brick missiles, causing structural damage, bodily injury and even death to those in the home. With the risk of a major earthquake in California always growing, its best to have your unused chimney removed sooner rather than later.

Your Chimney is Worn and Damaged

In an old and unkempt chimney, bricks may be weak and broken, and mortar may be worn away leaving the bricks insecure. If you’re not using your chimney, it’s easy to neglect chimney care. But a weak chimney faces the possibility of collapse at any time. If your chimney is old and worn it’s better to have it removed than leave it in place.

You Want More Valuable Space

Square footage is valuable in a home, and yet leaving an unused chimney in place can compromise your living space. Chimney removal can also help you access valuable living space in common areas and bedrooms. A chimney can impact the space in every level and room it passes through. Chimney removal offers the added benefit of easily accessing more precious space in your home, creating a more modern and comfortable living environment.

You Want To Remodel

Working around an existing chimney when you’re trying to remodel your home can be difficult and costly. In many cases, it can be easier and cheaper to just remove the chimney so you can plan and construct your remodel the way you want. This gives you more space to work with, and freedom from the constraints of needing to work around the chimney.

By contemplating when it really might be worth chimney removal, you can access significant safety and practical benefits. Talk to your local chimney sweep company today about the benefits you could gain from removing your chimney.
