Your chimney definitely doesn’t get the love it deserves, tirelessly venting smoke outside and enduring the harshest outdoor elements 365 days a year. But even the most durable chimneys inevitably sustain wear and tear over time. Damage ranging from minor surface cracks to extensive leaks and hazardous creosote buildup can sneak undetected.
This repair guide covers what to watch for and when to loop in a proven professional chimney company before small issues mushroom into catastrophic hazards or expenses.
The Age and Type of Your Chimney Matters
If you live in an older home, chances are your masonry chimney has seen some wear and tear over the years. Damage like exterior brick erosion and crumbling mortar joints can compromise the chimney’s structure over time. Newer factory-built metal chimneys aren’t invincible either — issues like rust and detached pipes also need addressing.
When you spot any deterioration on your chimney, calling a chimney pro to inspect and make repairs is crucial. They can pinpoint issues you’d miss and help restore structural stability before extensive repairs are necessary.
Don’t Ignore Small Cracks
It’s common to disregard minor cracks on your chimney or think they’re purely cosmetic. However, tiny exterior cracks often indicate interior damage or foundation problems you can’t see. As temperatures shift and seasons change, that small crack can rapidly expand, damaging masonry liners and tiles essential for ventilation.
Waiting too long can mean a full rebuild, so if you spot any crack — no matter the size — contact a chimney repair tech to inspect and seal it up with proper materials. This prevents further cracking and more serious safety issues over time.
When Creosote Buildup Becomes Dangerous
Creosote, a black resin-like substance, coats chimney flues and liners over time. Some buildup is normal from burning wood. But too much creosote creates a nasty fire hazard.
Beyond an annual chimney sweep to remove buildup, visible dripping stains on your chimney’s exterior likely mean an urgent repair. Left alone, liquid creosote seeps through cracks and deteriorates the masonry. It also ups your fire risk exponentially.
Chimney Leaks – It’s Never Just Water
Contrary to belief, chimney leaks involve much more than water damage. Other environmental contaminants like debris, animals, and excess elements gain unwanted interior access when the exterior bricks, crown, or flashing become compromised from wear.
While tiny drips may seem harmless initially, they allow destructive forces like moisture, pests, and dangerous gases inside the delicate flue system. Technicians from a professional chimney company often discover unseen oxidation and other ventilation issues while repairing minor leaks.
When to Call A Professional Chimney Company for Masonry Repairs
From crumbling mortar to replacing damaged exterior bricks, chimney pros are masonry experts equipped to restore stability and aesthetics. But at what point do these issues warrant calling them versus DIY repair?
Here’s a good rule of thumb: If cracks/holes exceed a reasonable size, say, a 1⁄4 inch, skipping professional help poses safety risks. Chimney foundations require precise specifications. Improper DIY repairs won’t withstand environmental factors over time.
Catching minor issues early and calling a professional chimney company for quality repairs is the best way to avoid damage and dangerous conditions over time.
