Water Leaks Destroy Masonry Chimneys

If you have a masonry chimney, you may already know how badly water can damage the bricks and mortar. The Chimney Safety Institute of America (CSIA) even states that water is the greatest enemy of masonry chimneys. Aelite Chimney Specialties understands how and why water leaks destroy the bricks and mortar of your chimney. Prolonged exposure to water speeds up the deterioration of masonry materials, but the worst damage is caused in the winter during the freeze/thaw process. When water leaks into the bricks and mortar of your chimney, it freezes and expands when the temperature drops. As that water thaws, it causes the masonry materials to crack from the cavity left by the expanded ice. If this type of damage is not repaired, your chimney Water Leaks Destroy Masonry Chimneys - Chicago IL - Aelite Chimineycould tilt and even collapse. Our CSIA-certified chimney technicians have years of experience with repairing water leaks as well as preventing these leaks from ever occurring. We would like to tell you about a couple of ways we can help stop water from penetrating into your masonry chimney to protect your chimney from destruction.


According to the CSIA, flashing keeps the water from rain and melted snow out of your chimney to stop it from leaking into the bricks and mortar as well as from getting into your home and damaging ceilings and walls. What exactly is flashing? The seal between the chimney and the roof, flashing consists of layers of sheet metal that overlap around your chimney where it meets with your roof. To work successfully, flashing should be professionally installed so that it can be custom-fitted to ensure an airtight seal. You can trust the chimney technicians at Aelite Chimney Specialties to do an expert flashing job that will protect the bricks and mortar of your chimney from damaging water leaks. Our technicians weave custom metal sheet work together, fold it against the chimney, and embed part of it into the mortar joints to create a superior flashing job. If you have noticed that your flashing has rusted, become loose, or if you have no flashing, contact us to learn more about our flashing services.


To prolong the life of your masonry chimney, waterproofing is recommended by the CSIA as a preventive measure against the damage done by water from rain, snow, and ice. When Aelite Chimney Specialties arrives at your home to waterproof your chimney, you can expect our CSIA-certified chimney sweeps to begin by cleaning your chimney. Our sweeps then apply a 100% vapor permeable formula to the entire length of your chimney. This formula allows your chimney to breathe so that vapors do not become trapped inside the bricks and mortar of your chimney to cause further damage. After the application, your chimney will be watertight with a professional grade water repellent treatment that has been proven to reduce water leaks by 99.9%. Waterproofing is a smart investment that can save you money in costly masonry repairs due to water damage.

Does Your Chimney Have Mold?

Mold in Chimney

Any trapped moisture in your home could be growing mold and deteriorating the quality of air in your home. Any mold growing in your home is serious and should be detected and removed immediately. Mold can produce respiratory problems and even some long term health effects. One of the biggest reasons for moisture or water entering the home is the most exposed to the elements structure in your home – your chimney.

Anytime moisture is trapped in your chimney, it provides a breeding ground for mold.

Detecting Mold

Mold is usually detected first by discoloration of ceilings and walls and can vary in color from white, black, or green. Fungi spores will also have a musty odor that is quite unpleasant. Cracks in paint or peeling might also appear around walls where mold is present. A white crystal like powder substance might also appear on bricks or mortar that does not give off an odor that is called efflorescence. Although this substance is NOT mold and mostly harmless, it IS and indicator of water leaks. If any discoloration around the mortar and bricks of the chimney, an inspection is recommended by a chimney professional, especially if water leaks or mold are suspected.

Mold and Health Problems

Exposure to mold can cause serious health problems including respiratory problems as well as nasal and sinus congestion. In a few instances, some might have allergic reaction to mold that results in headaches, cough, and irritation from the skin or throat. These symptoms might  be an indicator of mold in the home if not already detected. Seek a physician immediately if any negative reactions to exposure to mold occur.

Causes of Mold

Trapped moisture is always the cause of growing mold, but the million dollar question is where is the moisture getting in? It is not always easy to detect, but water always follows the path of least resistance. Professionals look for cracks, and a popular area for water to leak in is the flashing or area where the chimney is attached to the roof. Weathering and exposure to the elements of rain and snow can cause the flashing to develop cracks creating an area for moisture to get in the home. Whatever the reason, trapped moisture can cause mold to spread to the walls and ceilings, where it is the most difficult to treat and clean up.

Cleaning Up Mold

Cleaning mold is a dangerous job because of the risk of exposure to the toxic mold spores and should be done by a professional or with the utmost protection from skin, eyes, and lungs. Detection and fixing of the leak where the water is entering the home should be done first before cleaning mold. Making sure there are no leaks ensures clean up will only have to be done once. Water and a non-ammonia soap or detergent is all that is required to clean mold. After cleaning, the area should also be treated with a mild solution of water and bleach to completely disinfect the area.

Preventing Mold

In most cases, if a leak is fixed mold will stop growing. Keeping a dry home within 40-60 percent also keeps any type of mold growing. This can be done by using dehumidifiers if necessary in higher humidity climates. Never use carpet in bathrooms or basements and use mold repellent paint.

Keeping you home free from mold will keep you and your family healthy as well as protect your house for many years.
