To be sure your chimney does not suffer from spalling damage during the winter, it is important to have your chimney waterproofed. Water can cause so much damage and deterioration to masonry chimneys that the Chimney Safety Institute of America (CSIA) recommends protecting your chimney with various water penetration preventive measures, including waterproofing. The summer is the perfect time to waterproof your chimney, and Aelite Chimney Specialties can take care of this preventive task for you. We would like to tell you more about how water damages your chimney and how waterproofing can protect your chimney from deterioration.

What is spalling damage?Waterproofing and Spalling Damage - Chicago IL - Aelite

The bricks and mortar of your chimney are naturally porous, which means they absorb water from rain, ice, and snow. In the winter, any water that is trapped inside the masonry materials will freeze and expand whenever the temperature drops below 32 degrees Fahrenheit. When the weather warms back up, the water thaws out, and its force can cause the bricks and mortar to crack and break apart. This is spalling damage, and if this damage is left unrepaired, you could end up with serious structural issues, including the collapse of your chimney. Aelite Chimney Specialties has years of experience in masonry repairs, and we can replace any damaged or missing bricks and mortar joints to restore the soundness of your chimney’s structure.

How does waterproofing protect my chimney from spalling damage?

Waterproofing creates a barrier against water penetration and absorption. Aelite Chimney Specialties uses a waterproofing formula that is 100 percent vapor permeable, which means vapors can escape from the bricks and mortar. When we waterproof your chimney, we clean the exterior of the chimney by scrubbing away any mold, loose dirt, and debris and washing off any stains. We then apply the waterproofing formula to your entire chimney to protect it from water penetration. Waterproofing prolongs the life of your chimney and saves you the expense of masonry repairs. Your chimney will also be protected from efflorescence and other stains, and waterproofing also discourages the growth of mold, mildew, and other types of fungus.
Waterproofing your chimney is a good investment to keep your chimney working safely and efficiently. Aelite Chimney Specialties also provides other types of water penetration preventive services, including chimney cap and flashing repair and installation.
