Chimney Waterproofing — The Easy & Affordable Way To Prevent Chimney Leaks & Water Damage

Here at Sleep Easy, we want to make sure the chimneys of Kansas City stay strong, attractive, and in excellent condition, decade after decade — and we know that takes some effort and planning. But what can you do to prevent leaks and water damage, rather than react to them?

One of the smartest things you can do to ensure the longevity and integrity of your chimney is to invest in chimney waterproofing. After all, our chimneys face the beating rain, sleet, ice, and snow throughout the year, and all this moisture can cause deterioration and decay in the brick and mortar joints.

As masons, we know that masonry needs to be able to breathe and express vapor, but it also needs to be protected against water penetration if it’s going to last. Otherwise, you’ll see cracks, holes, and receding mortar joints, as well as discolored masonry and flaking brick along your chimney stack. That’s where chimney waterproofing comes in!

What Is Chimney Waterproofing?

The problem with masonry chimneys is that the brick and mortar are naturally porous, which means it absorbs moisture over time. The real problem occurs when this moisture in the brick freezes and thaws repeatedly. This freeze-thaw cycle creates immense pressure that can cause cracking, deterioration, and leaking quickly.

Simply put, waterproofing is the process of applying a special sealant to the exterior of your chimney, creating a barrier that repels water and prevents it from penetrating the brick and mortar.

There are a lot of waterproofing sealants sold at home improvement stores and online retailers,  but it’s important to use only those that have been approved for chimney applications. A sealant specifically designed for chimneys will be water repellent, but also vapor-permeable. This allows moisture vapor from within the chimney to escape, preventing trapped moisture and potential mold growth problems.

Here at Sleep Easy Chimney Service & Repair, we trust ChimneySaver water repellent. This 100% vapor-permeable product was designed exclusively for masonry chimneys and is 99.9% effective in preventing moisture penetration.
