If you smell gas, see smoke, or hear cracking from your Lakewood chimney, turn off the fireplace immediately, evacuate the home, and call 911. Then contact a licensed chimney sweep like Johnson Chimney Co. to assess structural or venting issues before winter’s first use. Never ignore these signs. Lakewood’s high-elevation climate accelerates creosote buildup and masonry wear, turning minor issues into emergencies fast.
1. What counts as a chimney emergency? (And how Lakewood’s weather increases the risk)
A chimney emergency is any situation where your fireplace or chimney poses an immediate risk of fire, carbon monoxide poisoning, or structural collapse. In Lakewood, where homes often sit on older foundations and the dry, windy air dries out masonry faster, these emergencies happen more often than in humid climates. The Chimney Safety Institute of America (CSIA) notes that creosote buildup, common in Lakewood’s wood-burning fireplaces, can ignite in as little as 18 months if not swept regularly. If you live near Bear Creek Park or along Wadsworth Boulevard, where older brick homes dominate, your chimney’s exposed to more seasonal stress from freeze-thaw cycles. Never wait to act: A gas smell, visible smoke, or loud cracking means your chimney’s failing in ways that could trap deadly gases or spark a blaze while you sleep.
2. The 7 chimney emergency signs in Lakewood, and what each means
Lakewood’s mix of older homes and modern gas inserts creates unique risks. Here’s what to watch for, ranked by urgency:
1. Gas smell (rotten eggs or chemical odor) This means natural gas or propane is leaking from a gas fireplace, furnace, or chimney vent. In Lakewood’s high-altitude homes, gas lines can corrode faster due to pressure changes. Action: Leave immediately, open windows, and call 911. Then contact a chimney sweep to check for improper venting or cracked flue tiles, common in homes near Belmar’s older neighborhoods.
2. Visible smoke inside your home Smoke pouring into a room signals a blocked or damaged chimney. If your fireplace is new but smoke backs up, the flue may be clogged with creosote or debris. Action: Stop using the fireplace, crack a window, and call a sweep. Lakewood’s dry air turns creosote into a flammable tar faster than in wetter areas.
3. Loud cracking or popping sounds Cracking masonry or explosive pops mean creosote is burning or your chimney’s structure is failing. If the sound comes from the roof or chimney crown, water damage may have weakened the bricks. Action: Evacuate if the noise is sudden, then inspect for spalling (flaking bricks) or missing mortar, a red flag in Lakewood’s freeze-thaw cycles.
4. Yellow or flickering flames (instead of blue) Yellow flames = incomplete combustion, which creates carbon monoxide (CO). In Lakewood’s older homes, this often happens when damp wood or a blocked chimney forces the stove to burn inefficiently. Action: Install a CO detector (required by Lakewood building codes) and schedule a chimney inspection before winter.
5. White, sooty stains on walls or ceilings Soot escaping into your home means gaps in the chimney or damper. If you see stains near ceiling fans or light fixtures, the flue may be cracked or disconnected. Action: Turn off the fireplace and call a sweep, this is a fire hazard and violates Lakewood’s chimney safety codes.
6. Animals nesting in your chimney Birds, squirrels, or raccoons can block your flue or chew through venting. In Lakewood’s suburban-wildland interface (near Red Rocks Park), this happens more often. Action: Never try to remove them yourself, carbon monoxide buildup is a real risk. Call a licensed sweep to safely relocate wildlife and inspect for damage.
7. Warped or rusted damper A damper that won’t stay closed or is rusted shut means moisture damage, common in Lakewood’s high humidity during monsoon season. Action: Replace the damper and check for water leaks in the chimney crown. The EPA’s Burn Wise program (the EPA's Burn Wise program warns that rusted dampers are a leading cause of chimney fires in Colorado.
3. What to do in a chimney emergency: Step-by-step Lakewood safety plan
If you spot any of the above signs, follow this exact order to protect your Lakewood home:
Step 1: Evacuate if there’s fire, smoke, or gas - Fire/smoke: Leave immediately, call 911, and do not re-enter until firefighters confirm it’s safe. - Gas smell: Open windows, turn off the gas line, and leave. Never use lighters or phones, sparks can ignite gas. - CO exposure: Get fresh air, call 911, and move to a well-ventilated area (like a car).
Step 2: Call for professional help - 911 for fires, gas leaks, or CO poisoning. - A licensed chimney sweep (like Johnson Chimney Co.) to inspect for structural damage, creosote fires, or venting issues. Lakewood’s building codes require inspections for resale or after emergencies, don’t skip this step.
Step 3: Document the damage Take photos of cracks, soot, or animal nests for insurance claims. In Lakewood, homes built before 1980 often have unlined chimneys, which are more prone to failures.
Step 4: Wait for clearance before using the fireplace Never light a fire until a certified chimney sweep confirms it’s safe. The NFPA’s (the National Fire Protection Association (NFPA) NFPA 211 standard states that a chimney must be inspected after any emergency use, even if you think it’s fine.
Pro Tip: Lakewood’s dry summers turn creosote into a highly flammable glaze. If you’ve gone more than a year without sweeping, assume your chimney is a fire risk and schedule an inspection today, before you light a single log.
4. Why Lakewood’s chimneys fail faster (and how to prevent emergencies)
Lakewood’s high elevation, dry climate, and older housing stock create perfect conditions for chimney emergencies. Here’s why:
- Creosote builds up 30% faster than in humid areas. The dry mountain air dries out wood faster, producing more tarry creosote. - Masonry cracks from freeze-thaw cycles. Lakewood’s hot summers and cold winters cause bricks to expand and contract, weakening mortar. - Gas lines corrode quicker due to pressure fluctuations at 5,500 feet elevation. - Wildland-urban interface risks. Homes near Genesee Park or Chatfield State Park face animal intrusions and debris blockages from nearby trees.
Prevention Tips for Lakewood Homeowners: - Sweep your chimney twice a year, once before winter and once after. Fall is the busiest season for chimney emergencies in Lakewood. - Use seasoned hardwood (oak or ash) to reduce creosote. Wet wood burns poorly, increasing CO risks. - Install a chimney cap to block animals, debris, and rain. Lakewood’s rainy springs cause major water damage. - Check your CO detector monthly. Lakewood’s older homes often lack proper ventilation, making CO poisoning a real threat. - Inspect your chimney after storms. High winds can displace caps or damage masonry, especially in Belmar’s older neighborhoods.
5. Chimney inspection vs. emergency repair: When to call a sweep vs. 911
Not every chimney issue is an emergency, but in Lakewood, delaying a repair can turn a small problem into a disaster. Here’s how to tell the difference:
| Issue | Is It an Emergency? | Next Steps | Cost Range (Lakewood) | |--------------------------|-------------------------|---------------------------------------------------------------------------------|----------------------------------| | Gas smell | YES | Call 911, evacuate, then a chimney sweep for venting checks. | $150–$300 (inspection + repair) | | Visible smoke in home | YES | Stop using fireplace, call a sweep for a Level 2 inspection /services/. | $200–$400 | | Loud cracking/popping | YES (if sudden) | Evacuate if fire risk, then inspect for creosote fires or masonry failure. | $250–$600 (repair + sweep) | | Yellow flames | NO (but urgent) | Install CO detector, schedule a sweep and inspection /contact/. | $120–$250 | | Soot on walls/ceilings | NO (but risky) | Call a sweep to check for gaps or blocked flues. | $150–$350 | | Animal nesting | NO (but dangerous) | Never remove yourself. CO risk. Call a sweep for humane removal. | $100–$250 | | Warped/rusted damper | NO (but high risk) | Replace damper and check for water damage in chimney crown. | $80–$200 |
Key Takeaway: If you’re unsure, err on the side of caution. Lakewood’s building codes require inspections after emergencies, and insurance may not cover damages if you ignored warning signs. Learn more about Lakewood’s most common chimney failures, and how to catch them early.
6. What Lakewood homeowners get wrong about chimney emergencies (and how to fix it)
Mistakes Lakewood homeowners make that worsen chimney emergencies:
Myth 1: ‘A little smoke is normal.’ Truth: Smoke inside your home means your chimney is failing. In Lakewood’s older homes, this often signals a collapsed flue liner, a fire hazard. Fix: Schedule a Level 2 inspection /services/ to check for structural damage.
Myth 2: ‘I’ll just open the damper wider.’ Truth: A stuck or warped damper can’t be forced open, it’s a safety risk. Lakewood’s humidity swings cause dampers to rust shut. Fix: Replace the damper and waterproof the chimney crown /blog/chimney-cap-installation-waterproofing-in-lakewood-protectio/.
Myth 3: ‘I’ll wait until winter to sweep.’ Truth: Fall is the worst time for chimney emergencies in Lakewood, creosote buildup from summer fires ignites when temperatures drop. Fix: Sweep before your first fire of the season. Book early, schedules fill fast.
Myth 4: ‘I can fix a cracked chimney myself.’ Truth: Masonry repair requires a licensed pro. DIY patches often fail in Lakewood’s freeze-thaw cycles, leading to water damage and CO leaks. Fix: Call a sweep to repoint mortar and seal cracks properly.
Myth 5: ‘My gas fireplace doesn’t need inspections.’ Truth: Gas fireplaces still need chimney checks, corroded venting or blocked flues can leak CO. Fix: Get an annual inspection as required by Lakewood code.
7. How to choose a Lakewood chimney sweep for emergencies (red flags to watch for)
When a chimney emergency hits, you need a licensed, insured sweep who responds fast. Here’s how to pick the right one for Lakewood:
Do This: - Ask for CSIA certification. The (the Chimney Safety Institute of America (CSIA) gold standard for chimney sweeps, required by Lakewood’s building codes for major repairs. - Check insurance. A liability policy protects you if damage occurs during service. Ask to see proof before they start. - Request a free emergency estimate. Reputable sweeps like Johnson Chimney Co. offer same-day inspections for urgent issues. - Look for local experience. A sweep familiar with Lakewood’s older brick homes (like those near Southwest Plaza) knows where failures hide.
Avoid These: - ‘Handymen’ or unlicensed workers. Lakewood fines homeowners for using uncertified chimney services. - Sweeps who won’t inspect after an emergency. Always get a post-emergency check, even if the immediate threat is gone. - Companies that pressure you into repairs. A real emergency requires immediate action, not upselling.
Pro Tip: Lakewood’s high demand in fall means schedules fill fast. Book a pre-season inspection now to avoid last-minute stress. Emergency fees can double if you wait until December.
| Emergency Sign | Is It a 911 Call? | Next Steps | Typical Cost (Lakewood) |

| Animal nesting in chimney | NO (but dangerous) | Never remove yourself, call a sweep for humane removal | $100–$250 |
Frequently Asked Questions
Your chimney smells like gas even when the fireplace is cold. Here’s what to do next.
This is a gas leak emergency. Leave your home immediately, open windows, and call 911. Never turn lights or appliances on or off, sparks can ignite the gas. After evacuating, contact a licensed chimney sweep to check for cracks in the flue or improper venting. Lakewood’s older gas lines (common in homes near Wadsworth) are prone to corrosion. Never ignore this, gas leaks can cause explosions.
Why does my Lakewood fireplace smoke when I light it, but the chimney was swept last year?
Smoke inside your home after a sweep usually means a blocked or damaged chimney. In Lakewood, this often happens because: - Animals nested in the flue (squirrels are common near Bear Creek). - Creosote built up faster than expected (Lakewood’s dry air accelerates buildup). - The damper is stuck or warped (rust from moisture is a big issue here). Action: Stop using the fireplace, call a chimney sweep for a Level 2 inspection, and check for obstructions or structural damage.
I heard cracking sounds from my chimney last night. Is that normal?
No, loud cracking is never normal, it’s a warning sign of danger. In Lakewood, this usually means: - Creosote is burning (a chimney fire, evacuate immediately). - Masonry is cracking from freeze-thaw cycles (common in older brick homes). - The chimney crown is failing (water damage weakens bricks). Action: If the cracking was sudden or explosive, leave the house and call 911. Then contact a chimney sweep to inspect for structural failure or hidden fires. Never use the fireplace again until it’s cleared.
My gas fireplace runs all winter, why can’t I skip chimney checks?
Yes, gas fireplaces still need inspections. Even though they don’t burn wood, venting issues, corrosion, or blocked flues can leak carbon monoxide (CO). Lakewood’s high altitude increases the risk of gas line corrosion and improper venting. The CSIA recommends annual inspections for gas fireplaces to check for: - Corroded vent pipes - Loose connections - CO leaks Skipping inspections violates Lakewood’s building codes and puts your family at risk.
