Top Five Things To Look For When Hiring A Chimney Sweep

What causes cracks in your chimney and chimney flue? The answer matters -- if you don't think your chimney will develop cracks, you won't keep an eye out for them. And then you won't have the opportunity to make a quick repair before a small problem grows into a big one. That "big problem" can range from expensive repointing/brick replacement to dangerous gases leaking into your home, threatening the health of you and your family.

Here are five signs you have increased risk for chimney cracks:

The first step to determining if the flashing is the cause of the leak is to examine the chimney. The weakest points of the chimney are the top and sides. These are the areas that face the greatest UV and weather exposure, and therefore damage. Since is better protected, you will notice the side facing the ground does not have flashing. Inspect the base area for cracks or areas of water penetration.

The brick and mortar will expand and contract with seasonal change. Since the mortar is not elastomeric, this expansion and contraction can cause cracks. In addition, mortar is very porous and absorbs water that will freeze in cold climates. This freezing and thawing will destroy the mortar joint causing a potential leak and degrading the structural integrity of the chimney over time. Inspect the mortar joints for cracks.

If there are cracks in the chimney use a clear exterior elastomeric caulk to seal the cracks. You can also use an exterior masonary waterproofing sealant to coat the entire chimney. Be sure to use a clear elastomeric waterproofing sealant to maintain the color of the brick and mortar.

While this method may work temporarily, many professional contractors with years of experience with leaning chimneys do not recommend this repair method. Ultimately, strapping the flue to the home does not resolve the issue of the settling with causes the movement of the chimney. This is a temporary fix that is not likely to offer long term success for some leaning chimneys.

There are more permanent, reliable options for leaning chimney repair. In order to determine the best method for repair the contractor will have to identify the cause of the settlement. Determining the source of the settlement is important to helping the contractor suggest the best method to fix the problem on a permanent basis. Those chimneys with very little foundation damage may be able to be repaired with the insertion of pins or stabilized with the insertion of a flue.

Chimney Repair

Cracks, leaks, and other problems can lead to house fires, carbon monoxide poisoning, and potentially dangerous situations, so it's important to follow up your chimney inspection with all necessary repairs. Chimney repair is always a job for professionals, so be sure that you use a qualified technician for complete, correct repair to keep your house and family safe. Common repairs include brick repointing, relining, and cap installation.

Repointing and Brickwork Repair: If the mortar in your chimney is eroding, it needs to be repointed. The mortar is essentially the glue holding the bricks in place, so if it begins to deteriorate, the bricks are no longer solidly held together--your chimney may crumble or collapse! Repointing ensures that the bricks remain in place and your chimney's structure stays sturdy. Missing or broken bricks should also be replaced to keep it looking and working great. Mortar repointing and brick repair not only address aesthetic issues, but they can also resolve chimney leaks and prevent deterioration.

Relining: Many older chimneys are lined with fireproof tiles or clay, but these materials can crack because of chimney fires and other problems. Once cracked, your liner can no longer do its job of protecting your chimney from extreme heat and preventing carbon monoxide leakage. This tile or clay liner should be replaced with a modern stainless steel lining for optimum protection.
