Chimney Waterproofing – signs you may need it.

Why do you need Chimney Waterproofing

If you want your chimney to last your going to need some Chimney Waterproofing. Resistance to water penetration into the brick and mortar is key to your Chimney’s lifespan. Water can cause deterioration, corrosion, efflorescence, spalling of the bricks, and if left unchecked will cause structural failure.

Erosion

Severe erosion and deterioration is caused by water penetration. Bricks will begin to crumble as the water damage becomes for severe. This is not safe and should be addressed immediate! After repairs are done, a water repellent treatment will protect the repair and rest of the structure against further damage.

Efflorescence

The white stains, on the bricks below, are called efflorescence. This indicates that water penetration and salts are present and migrating to the surface. In other words, its a sign that moisture problems are taking hold. Call Advanced Chimney inc immediately if you see this white staining. This means you certainly have a moisture problem. We will inspect and access the damage. Only then can we  make the proper recommendations.

Spalling

Water also causes damage during the freeze/thaw cycles we experience in our area, leading to structural failure and spalling. This is when the face of the brick begins to separate and as a result may even fall off. If you notice pieces of brick laying at the bottom of your chimney, it’s time to call in the experts to prevent further damage.

Inspection

Advanced Chimney technicians will inspect your your chimney in detail.  Our Techs can spot hairline cracks and openings in mortar. These will most likely need to be repaired as well as treated. If the liner is letting moisture into your masonry, a new stainless steel liner may be recommended. The most common solution offered to reduce the amount of water entering your chimney is a chimney waterproofing. This is a coating of a water repellent solution that forms a barrier against moisture intrusion.

Your chimney is constantly battling elements such as driving rains, repeated freezing and thawing cycles and high winds.

The other way moisture gets into your chimney is from the inside out. The gases that escape out your flue contain water vapor. That moisture will work its way through any breaches in the liner and thus into your masonry chimney walls.
