Your Lakewood chimney isn’t just a vent, it’s a fire and carbon monoxide hazard if ignored. Creosote buildup, cracked masonry, and blocked flues cause 25,000+ house fires yearly. You can spot early warning signs yourself, but repairs like relining or repointing must be done by certified pros like Johnson Chimney Co. Start with these safety checks before winter hits.
The 3 Most Dangerous Chimney Risks in Lakewood Homes (And How to Spot Them)
Lakewood’s dry winters and high-elevation winds create perfect conditions for chimney hazards. The top three risks are: 1. Creosote buildup: A sticky, flammable tar that coats flue walls, it’s the #1 cause of chimney fires. If you see black, sooty residue in your fireplace or a strong tar smell, your chimney needs a sweep now. Learn more about creosote risks here. 2. Carbon monoxide (CO) leaks: Faulty drafts or blocked flues force CO into your home. Symptoms? Headaches, nausea, or dizziness near the fireplace. Install a CO detector above the fireplace, not just near bedrooms. 3. Masonry damage: Cracks in brick or mortar let rain seep in, weakening the chimney. Check for crumbling mortar or rust stains on the roof, both mean water’s getting in. Lakewood’s freeze-thaw cycles accelerate this damage.
Safe DIY check: Use a flashlight to inspect the fireplace opening and chimney cap from the roof (if it’s safe to access). If you spot gaps bigger than a quarter, get a professional in right away.
5 Chimney Upkeep Tasks Southglenn Homeowners Can Handle Safely
Not all chimney work requires a ladder and a crew. These tasks keep your system running safely between professional sweeps: 1. Clear debris from the fireplace: Remove ash and soot after each use with a metal bucket and shovel. Never use a vacuum, flying embers can ignite dust. 2. Inspect the chimney cap: Ensure it’s secure and free of leaves/nesting debris. A loose cap lets rain and critters in. See how to check your cap here. 3. Test your draft: Light a small piece of newspaper near the fireplace opening. If smoke billows into the room instead of up the flue, your chimney has a blockage or poor draft, stop using it and call Johnson Chimney Co. 4. Seal air leaks: Use high-temperature sealant around the fireplace hearth to block drafts. Avoid caulk near the flue opening. 5. Check for animal nests: Listen for scratching or see droppings in the fireplace. A blocked chimney is a fire hazard. Learn how to safely remove nests.
Pro tip: Schedule your annual chimney sweep in Lakewood before October, fall is peak season, and delays mean higher costs. Book now to avoid the rush.
WARNING SIGNS: When Your Lakewood Chimney Needs a Professional Immediately
Some problems look minor but hide serious risks. If you see any of these, stop using your fireplace and call Johnson Chimney Co: - Smoke or soot in the room: Means the flue is blocked or the draft is failing. DIY fixes (like adding more wood) won’t help, this requires a sweep or reline. - Rust stains on the roof: Water leaking from the chimney corrodes metal flashing and can rot your roof. See how waterproofing works. - Cracked or bulging flue liner: A cracked liner can’t contain heat or gases, it’s a fire and CO risk. Compare repair vs. replace costs. - Burning smell with no visible fire: Creosote fires often start this way. If you smell something acrid, evacuate and call us. - Sagging or leaning masonry: A chimney that’s visibly tilting is a structural hazard. Lakewood’s older homes often have unreinforced brick, this isn’t a DIY fix.
Why wait? A blocked flue can fill your home with CO in minutes. See our service area, we respond to emergencies in Lakewood, Golden, and Wheat Ridge.
Southglenn DIY Mistakes That Risk Your Home (And How to Avoid Them)
Some chimney work seems simple, but mistakes here cost lives, and money. Avoid these: - Removing creosote: Scraping it with a brush or wire can spark a fire. Creosote removal requires specialized tools and ventilation. - Repairing a cracked flue liner: DIY patches won’t withstand heat or pressure. A relined chimney costs $1,500–$3,000, but a failed patch can destroy your home. - Cutting down a tall chimney: Altering the height affects draft and may violate Lakewood building codes. Learn about code compliance. - Ignoring a blocked chimney: Using your fireplace with a blocked flue forces CO into your home. See how inspections differ from sweeps.
Insurance note: Many homeowners’ policies won’t cover chimney-related fires if you skipped required maintenance. Check your policy before attempting repairs.

Frequently Asked Questions
My Southglenn fireplace smells like gas even when it’s off, what’s causing it?
That’s carbon monoxide escaping from a clogged or cracked flue. Stop using the fireplace immediately and crack windows for airflow. CO has no smell and is deadly, contact Johnson Chimney Co for an urgent check. Spot CO warning signs and place a detector above the fireplace.
Why does my chimney in Lakewood keep getting clogged with leaves and debris?
A broken or missing chimney cap is likely the issue. Southglenn’s fall winds push leaves and pine needles straight into your flue. Fit a stainless-steel cap with a mesh screen to stop debris buildup. See how caps block debris, or let us check yours before the cold sets in.
I found black, tarry residue on my fireplace tools, is this normal?
No, that’s Stage 3 creosote, the most dangerous type. It’s glossy, hard, and can ignite at any time. Stop using the fireplace and schedule a chimney sweep within 48 hours. See creosote removal costs, this isn’t a DIY job.
