Masonry Damaged Repaired

When you have a masonry chimney, you should know how important it is to spot damaged bricks and mortar joints early. This keeps the damage from becoming too expensive and extensive! Masonry materials are naturally porous, which means they suffer from erosion damage easily. If you notice any cracked bricks, All American Chimney Service is here to help you maintain the soundness of your chimney’s structure by promptly repairing that damage. We are trained and experienced in masonry techniques like tuckpointing. This will restore the structural soundness of your chimney. We would like to tell you more about what to look for to spot masonry damage in its early stages.


One of the earliest signs of damaged chimney masonry is cracked bricks and mortar joints. This type of damage typically occurs during the winter. Any moisture trapped inside the masonry materials will freeze and expand whenever the temperature falls below 32 degrees Fahrenheit. When the weather warms back up, the force of the water thawing can cause the bricks and mortar joints to crack and break apart. Repeated freeze/thaw cycles can lead to extensive masonry damage. All American Chimney Service can keep your chimney from suffering structural damage. We do this by replacing damaged bricks and mortar joints with our tuckpointing skills. We can also waterproof your chimney to prevent freeze/thaw damage from occurring in the future.


Since your chimney crown’s location is at the very top of your chimney, it is directly exposed to the elements of the weather. Even though your crown has been treated to withstand exposure to water, it can weaken over the years and begin to crack and chip away. According to Inspectapedia,chimney crown damagecan lead to further water deterioration of the chimney and flue. Also, to hazards such as fires and carbon monoxide leaks. All American Chimney Service provides professional chimney crown repair and construction services that will protect your chimney from water penetration damage and hazards!


If you notice white stains on the exterior of your chimney, you are seeing the signs of water penetration. Known as efflorescence, these stains are the result of moisture entering the bricks and bringing salt to the exterior surface. When you notice these stains on your chimney, give All American Chimney Service a call to schedule a chimney leak inspection. We will locate the source of the water penetration and make the necessary repairs, including cleaning off the efflorescence stains.
