Is Masonry Absorbent? 

Yes, masonry materials – your brickwork and mortar – are very absorbent and will soak in a lot of water over time if they aren’t adequately protected. This can result in freeze/thaw damage, where the water in the brick freezes, expands, and contracts as a result of temperature changes, causing decay, deterioration, and cracking in the process. When this happens, brick can essentially implode and cracks and other damage can occur.

Not only can this type of damage allow even more water into the masonry and home and lead to leaks and water problems, but it can also compromise the service life and integrity of the chimney. That’s where our chimney water repellents come in. These repellents work to keep any water from absorbing – rather, it simply beads up and rolls right off the brickwork.

…but what about water that’s already been absorbed? Well, it’s this very concern that brings us to another common question: 

Can I DIY Chimney Waterproofing?

Waterproofing chimney brickwork on your own isn’t recommended, despite the appeal of those hardware store water repellents. Oftentimes, these products, as well as paints and other sealers, actually trap the moisture inside of the brickwork. This means, while nothing will be getting in, nothing can get out either. Rather, water remains trapped, where it continues to break things down.

Here at Leonard & Sons Building Service, we’re proud to use ChimneySaver masonry water repellent, which is the only masonry water repellent developed specifically for chimneys. When applied by a knowledgeable professional, this amazing product can reduce masonry water penetration by 99.9 percent, essentially eliminating water concerns altogether. And best yet, it’s 100% vapor-permeable, so it won’t trap in pre-absorbed water or water vapors produced by combustion.

Aside from its incredible ability to reduce moisture penetration and ensure breathability, what else makes ChimneySaver water repellent such a great option?

• It provides 10 years of protection against masonry water leaks, efflorescence, stains, mildew, and fungus.
• It doesn’t leave a glossy look on your masonry — in fact, no one will know it’s there except for you and the professional applying it.
• It prevents the cracking and spalling that can happen as a result of expansion and contraction during the freeze/thaw cycle.
• It’s water-based and safe for the environment.

If it sounds too good to be true, it’s not! ChimneySaver is proven to work – guaranteed!
