If you live in the Sacramento area and Googled something like “waterproofing chimney,” chances are your chimney has sprung a leak and your Internet search has brought you to the A to Z Chimney Sweep site. Well, you’re in the right place! In business since 1995, we have yet to meet a chimney leak we can’t repair, and we almost always recommend that our customers have us follow leak resolution by also having their chimney professionally waterproofed.
If you’re not sure if your masonry chimney is leaking or not, you can look for the following signs: stained ceilings or wall coverings around the fireplace, stained chimney brick, crumbling brick or mortar, mold or efflorescence on or around the chimney, etc. Musty smells and dripping sounds are also dead giveaways that water has accessed your chimney. You will want to keep water out to prevent the spread of more damage, which can quickly become costly to repair.
Waterproofing is a preventative measure—something we prefer to do prior to any leaks—but it’s also a great thing to do after a leak has been repaired so that leaks won’t happen again. By applying a semi-permeable membrane called ChimneySaver to the exterior of your chimney we allow your chimney to “breathe” while keeping water out of your porous chimney brick and masonry. ChimneySaver comes with a 10 year limited warranty. In our experience, it really works for our customers.
What Else Can I Do to Keep Water Out of My Chimney?
In addition to waterproofing, there are a number of great ways to keep water out of your chimney, including:
- Install a chimney cap or top-sealing damper
- Install new flashing or repair existing flashing, counterflashing, or crickets
- If needed, undertake any masonry repairs
Only a certified chimney technician will be able to tell you for sure what is causing your chimney to leak and to advise you on how best to fix this. The good news is that most of these repairs come with additional benefits—like energy savings or increased efficiency. Plus, they’ll help increase the value of your home and make your fires safer to burn.
If you have any questions about waterproofing a chimney or if you need to schedule a chimney inspection, we hope you’ll contact A to Z Chimney Sweep.
