Looking at your brick chimney, it's easy to picture it as the Hercules of house features. Strong, sturdy, laughing in the face of Mother Nature's tempestuous tantrums...until it meets water, its Achilles heel.
Bricks and mortar, much like your favorite sponge, love to soak up water. That's great for your sponge, but disastrous for your chimney, especially if it's a bit worse for wear or was put together by a subpar builder on a friday afternoon. As winter swoops in, the waterlogged bricks freeze, and those innocent droplets morph into ice demons, expanding and turning your bricks into a crumbling flaky mess!
So, how do you spot a chimney crying out for a lifeline? Well, if your bricks are flaking like a stale croissant, congratulations, you've got 'spalling'! White, powdery stuff on your bricks? That's efflorescence, which are salt and minerals that have being leached out of the brick. Spotting dark stains or moss settling in? Time to call in the chimney experts.
But let's talk prevention. Here's a handy guide to help your chimney fend off its watery foe:
DIY Doctor: Keep a close eye on your chimney. Those cracks and chips aren't going to fix themselves!
Chimney Hats: A cap on your chimney isn't just a fashion statement, it's like an umbrella in a storm, keeping the rain and snow at bay. (They keep unwanted animals out too!)
Crown Jewels: Your chimney crown needs TLC too. Keep it crack-free to avoid water waltzing in uninvited.
Flashing Alert: Ensure your chimney flashing isn't more of a 'flashing failure.' This unsung hero stops water sneaking through gaps between the chimney and the roof.
Every Hero Needs a Shield: Have a professional install water repellent on your chimney's exposed bits. It's like Gore-Tex, but for bricks!
Gassy Business: Improperly installed or maintained water heaters, furnaces, and gas fireplaces are your chimney's inside enemies, pumping out water vapor like there's no tomorrow. Keep them in check with stainless steel liners and regular maintenance.
Nothing lasts forever - not even Hercules.. But with some the right knowledge and preventative measures, your chimney can continue its epic face-off against water for many more years to come!
