In Denver, brick and masonry chimneys should be inspected annually and swept every 1–2 years, or more often if you burn wood frequently. Homeowners can safely check for creosote buildup and loose bricks, but never attempt repairs or deep cleaning. When in doubt, call a licensed chimney sweep like Juniper Chimney Inc to avoid costly damage or fire hazards.
Denver’s Chimney Service Schedule: Brick & Masonry Chimneys
Denver’s older homes often feature brick or masonry chimneys, which require more frequent attention than modern prefab units. Annual inspections are critical, especially before winter, to catch cracks, mortar deterioration, or liner issues. Sweeping should happen every 1–2 years for gas fireplaces and once a year for wood-burning chimneys. If your chimney is used daily (like in historic Denver neighborhoods with cast-iron stoves), schedule sweeps twice a year. Check our Denver service area to confirm your home’s specific needs.
Quick, safe fireplace creosote tests for older-home owners who’d rather not call a pro, yet
Before your next professional chimney sweep, perform these safe, visual checks from a ladder or roof access (never climb on unstable masonry!). 1. Inspect the crown (top of chimney) for cracks or missing mortar. Denver’s freeze-thaw cycles accelerate wear. 2. Look for creosote (black, tar-like buildup) in the firebox or smoke chamber; even a thin layer signals it’s time for a sweep. 3. Check for loose bricks or mortar joints near the flue, tap gently with a tool (no hammer!). 4. Test draft strength by lighting a match near the damper: a strong pull means clear airflow; weak drafts mean obstruction. Learn more DIY tips, but stop if you see rust, soot beyond the firebox, or structural damage.

If you spot these warning signs in your pre-1950s masonry chimney, shut down the fireplace and grab the phone, no exceptions Rust or corrosion on the damper, smoke chamber, or liner, common in Denver’s humid summers and old brickwork. 2. Foul odors or smoke in the house (not just the chimney), which could mean a cracked flue or blocked liner. 3. Excessive creosote (glossy, tarry buildup) or soot in the firebox beyond normal levels, both are fire hazards. 4. Cracked or spalling bricks (flaking mortar) near the flue, which can let carbon monoxide into your home. 5. Animals nesting (birds, squirrels) or unusual noises (scraping, rustling) inside the chimney. See our comparison guide on why these issues require a pro.
DIY chimney ‘fixes’ that’ll turn your Washington Park brick liner into a tinderbox, don’t try these
Avoid these dangerous DIY traps that void warranties, risk injury, or damage your chimney: 1. Removing creosote with abrasive tools or chemicals, it’s toxic and can corrode liners. 2. Repairing cracks in the flue or crown with mortar alone; improper fixes let moisture seep in, causing spalling bricks. 3. Ignoring a damaged chimney cap. DIY replacements often don’t seal properly, letting rain and debris enter. 4. Attempting liner repairs without specialized tools (like a chimney camera inspection). 5. Using your fireplace after seeing any of the warning signs above. Denver’s older homes often have hidden masonry issues, like a collapsed liner, that only a professional inspection can detect. Review our repair vs. replace guide for context on when DIY fails.

Frequently Asked Questions
My Denver home’s chimney is made of brick, does it need more frequent service than a metal one?
Yes. Brick chimneys in Denver require annual inspections and sweeping every 1–2 years because mortar joints degrade faster in our freeze-thaw cycles. Metal chimneys (like those in newer homes) last longer but still need checks for rust or liner corrosion. Learn about Denver’s older-home chimney quirks.
Why does my chimney smell like gas even after a sweep? Could it be a DIY fix?
No, this is a dangerous sign of a cracked flue, failed liner, or gas appliance leak. Never DIY this. Denver’s older homes often have hidden masonry cracks that let carbon monoxide seep into living spaces. Call us immediately for a Level 2 inspection with a chimney camera to locate the issue.
I live in Wheat Ridge, should I wait for winter to schedule a chimney sweep, or go now?
Schedule now. Wheat Ridge’s high elevation and dry summers mean creosote builds up faster in wood-burning chimneys. A pre-winter sweep ensures your chimney is safe for holiday fires. See our Wheat Ridge service details for local scheduling tips.
