Your Denver chimney is a fire hazard if ignored. You can safely inspect it yourself twice a year, but never climb inside or attempt deep cleaning. Watch for smoke smell, soot buildup, or rust, these mean stop DIY and call a licensed chimney sweep. Gopher Chimney Co handles the dangerous work so you stay safe and code-compliant.
What Denver Homeowners Can Safely Do Themselves (Without Risking Injury or Fines)
Denver’s dry mountain air and high-elevation wood-burning habits mean chimneys need extra care. Start by inspecting the outside every 3 months: look for cracks, missing mortar, or rust on the cap. Use a flashlight to check the damper, if it’s stuck or warped, that’s a red flag. Never poke inside with tools or climb onto the roof. For the fireplace, wipe down the hearth with a damp cloth after each use to catch falling soot. If you smell gas or see white powder (lime), stop using the fireplace immediately and call a pro.

Step-by-Step: How to Spot Dangerous Chimney Problems Before They Start
Denver’s sudden temperature swings and moisture from snowmelt accelerate chimney damage. Inside the fireplace, check for: 1) Glossy black tar (creosote) on walls, this is flammable and builds up fast in Denver’s dry climate. 2) White, chalky residue (lime), a sign of poor combustion or a cracked flue. Outside, look for: 1) Rust on the chimney cap or crown. 2) Cracks wider than 3/8 inch. 3) Water stains or mold near the base. If you see any of these, do not use the fireplace and schedule a professional inspection. See our full Denver safety checklist for what to document before calling a sweep.
Your Chimney’s Red Flags: When a DIY Fix Could Start a Fire in Your South Broadway Home
These are never safe to ignore or attempt yourself: 1) Smoke or fumes in the house when the fireplace is lit, this means carbon monoxide risk and a blocked or cracked flue. 2) Orange or yellow flames instead of blue, signs of poor ventilation or creosote buildup. 3) Animals nesting in the chimney (birds, squirrels), their debris blocks airflow and creates fire hazards. 4) Structural damage like leaning bricks or a collapsed crown. 5) Gas smell after lighting the fireplace, indicates a gas leak or improper venting. If you see any, evacuate the area, open windows, and call Gopher Chimney Co immediately. Emergency services are available 24/7 for these critical issues.
When to Call Gopher Chimney Co: Denver’s Licensed Experts for the Dangerous Work
You should call us before winter if: 1) It’s been over a year since your last professional chimney sweep (Denver’s dry air means creosote builds faster). 2) You’re switching to wood-burning after using gas, wood creates more creosote and requires a deeper clean. 3) Your chimney is over 20 years old (mortar deteriorates faster in Denver’s freeze-thaw cycles). 4) You’ve had repairs done, we’ll inspect for proper installation. Our crews are trained to handle roof access, flue relining, and creosote removal, tasks that require OSHA-certified safety gear and equipment you shouldn’t attempt. Book a visit or ask about our Denver service areas, including Arvada, Aurora, and Lakewood. Compare DIY risks vs. professional cleaning here to see why pros are worth the investment.
Why Skipping a Pro for Your Chimney in Washington Park Could Cost You More Than Money
Attempting these will void warranties, violate Denver building codes, and put your home at risk: 1) Climbing onto the roof to clean the chimney, falls from Denver’s steep roofs are common and often fatal. 2) Chemical chimney cleaners, they damage metal liners and release harmful fumes during use. 3) Ignoring a blocked flue, even if the fireplace seems to work, carbon monoxide can still leak. 4) Skipping annual inspections. Denver’s high altitude affects combustion, and undetected issues can lead to chimney fires. 5) DIY repairs like patching cracks with cement, this traps moisture and accelerates damage. See our comparison guide on repairing vs. replacing chimneys to understand why some fixes require a pro’s touch.
Denver-Specific Chimney Care: Adapting to Our Unique Climate and Codes
Denver’s thin air and rapid temperature shifts demand extra attention. Before winter, have us check your chimney cap, our crews install stainless steel models that withstand hail and high winds, common in the Front Range. If you burn pine or oak (popular local woods), schedule a sweep twice a year, these create more creosote. For gas fireplaces, annual inspections are mandatory per Denver County codes.

Frequently Asked Questions
My chimney smells like gas when I light the fireplace, what’s wrong and should I call someone right away?
Yes, call Gopher Chimney Co immediately. A gas smell means either a gas leak (if you have a gas fireplace) or blocked flue trapping combustion gases. Never ignore this, carbon monoxide poisoning is silent and deadly. Open windows, evacuate the area, and let us inspect for cracks, animal nests, or improper venting. See our emergency chimney services for 24/7 response times.
I see white powder near my fireplace, could this be dangerous, and should I try to remove it myself?
That’s lime, a byproduct of burning wood or poor combustion. It’s not immediately toxic, but it signals moisture in the flue or a cracked chimney liner, both fire hazards. Do not scrub it with abrasives, it’ll damage the masonry. Instead, stop using the fireplace and call us to check for leaks or reline if needed. Learn about flue relining costs and signs you need it.
My chimney looks fine, but my insurance company says I need a ‘Level 2’ inspection, what does that mean, and why won’t they cover a DIY sweep?
A Level 2 inspection (required after repairs or if your chimney shows signs of damage) means a pro must disassemble parts of the chimney to check for hidden issues like internal cracks or corrosion. Insurance companies won’t cover DIY work because undiscovered damage can void your policy if a claim arises. We offer inspection-only services for $120–$200 in Denver, which often uncovers problems like rusted damper rods or missing flashing, common in older homes. See our Denver inspection services for details.
