If your chimney shows soot stains on walls, a strong smoke smell after lighting a fire, or a cracked crown, you need an emergency chimney sweep in Aurora today. Denver’s dry climate and older brick homes make creosote buildup a hidden fire hazard. Call a licensed sweep immediately, carbon monoxide poisoning from blocked flues sends 50+ Coloradans to the ER yearly USA.gov. Never ignore these signs: delay risks your family’s safety and violates NFPA 211 fire codes the National Fire Protection Association (NFPA)|https://www.nfpa.org/)).
1. What is an emergency chimney sweep? (And why Aurora’s climate makes it critical)
An emergency chimney sweep is a same-day inspection and cleaning for immediate hazards like blocked flues, cracked liners, or active creosote fires. Aurora’s high-altitude dry air and older homes (many built before 1980 with unlined chimneys) create perfect conditions for creosote, a flammable tar that builds faster in Denver’s thin oxygen. The Chimney Safety Institute of America (CSIA) warns that unburned creosote can ignite at 1,100°F, hotter than most house fires the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)). If you’ve noticed any of the 7 signs below, schedule an emergency sweep before winter’s first freeze locks you out of service. Lizard Chimney Inc serves Aurora with 24/7 emergency response.
2. Myth: ‘My chimney looks fine, it’s not an emergency.’ (What Aurora homeowners miss)
Most Aurora homeowners wait until they see smoke or smell gas, but by then, carbon monoxide (CO) may already be seeping into your home. CO is odorless and kills 430 Americans yearly USA.gov, and Denver’s older brick homes with deteriorating mortar are prime leak points. A chimney sweep near you can spot these hidden dangers during a Level 2 inspection (which examines the flue, smoke chamber, and connector pipe). For example: - A ‘clean’ chimney that still smells like smoke after lighting a fire often means creosote dust has coated the flue walls, reducing draw and forcing CO into your home. - White powdery residue on your fireplace hearth isn’t just ash, it’s sulfur deposits from untreated wood, a sign your chimney isn’t venting properly. - Animals nesting in your chimney (common in Aurora’s vacant summer homes) block airflow and create fire hazards. Learn how to check for animal blockages safely.
3. 7 urgent signs you need an emergency chimney sweep in Aurora, CO right now
Aurora’s mix of older homes and modern gas fireplaces creates unique risks. Here’s what triggers an emergency call: 1. Smoke backing into your home when you light a fire, this means negative pressure (often from a blocked or collapsed flue) is pushing CO indoors. 2. A loud roaring or popping sound from the chimney, which could signal a chimney fire (Denver’s dry winters make these more likely in unlined flues). 3. Yellow or flickering flames instead of blue, this indicates incomplete combustion, a CO risk and a sign of creosote buildup. 4. Cracks in the chimney crown (the top cap) or missing mortar joints, water leaks erode brick faster in Aurora’s freeze-thaw cycles, weakening the structure. 5. Soot stains on walls or ceilings above the fireplace, meaning smoke isn’t venting and CO is escaping. 6. Your carbon monoxide detector alarms when you use the fireplace, never ignore this. CO from a blocked chimney is silent until it’s too late. 7. You haven’t swept since last winter. Denver’s NFPA 211 code requires annual inspections for wood-burning fireplaces the National Fire Protection Association (NFPA)|https://www.nfpa.org/)), and gas fireplaces need checks every 2 years. See Aurora’s specific chimney sweep costs.
4. ‘I called a sweep last year, why is this an emergency?’ (When Denver’s rules change)
Annual sweeps are the minimum for safety, but three factors can turn a routine cleaning into an emergency in Aurora: - You switched to a hotter-burning wood (like oak or hickory) without adjusting your sweep schedule, these create Stage 2 creosote (hard, glass-like buildup) in as little as one season. - Your home sat vacant during summer, animals (like raccoons or birds) nest in chimneys, blocking flues and creating fire risks. - Denver’s new 2024 burn bans (triggered by high pollution days) force you to stop using your fireplace until the chimney is cleared, don’t wait for a ban to act. Check if your chimney meets Denver’s updated fire codes. Pro tip: If your sweep finds more than 1/8-inch of creosote, schedule a second cleaning, this is the NFPA’s threshold for high risk the National Fire Protection Association (NFPA)|https://www.nfpa.org/)).
5. Who to call for an emergency chimney sweep in Aurora: 3 questions to ask before you hire
Not all chimney sweeps in Aurora are equal, especially for emergencies. Ask these three questions to avoid scams or unsafe crews: 1. ‘Are you CSIA-certified and insured?’ - Why it matters: CSIA-certified sweeps follow national safety standards the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)), and insurance protects you if damage occurs. Lizard Chimney Inc holds active CSIA certification and $2M liability coverage. 2. ‘Can you perform a Level 2 inspection today?’ - Why it matters: A Level 1 (visual) inspection won’t catch hidden flue blockages or liner cracks. A Level 2 (which includes removing obstructions) is required if you suspect CO risks or a chimney fire. 3. ‘Do you offer emergency same-day service for Aurora residents?’ - Why it matters: Some sweeps book weeks out. Lizard Chimney Inc guarantees same-day response for Aurora emergencies, including weekends. Request an emergency estimate now.
6. What happens during an emergency chimney sweep? (Step-by-step for Aurora homes)
An emergency sweep in Aurora follows this safety-first process: 1. Safety check: The technician tests for CO levels near the fireplace and inspects for structural damage (like leaning masonry). 2. Flue inspection: Using a chimney camera, they check for creosote buildup, cracks, or animal nests, common in Aurora’s older homes. 3. Cleaning: If creosote is found, they use rotary brushes or chemical cleaners (for Stage 2 buildup) to remove it safely. 4. Repair recommendations: If the crown, liner, or mortar is damaged, they’ll outline code-compliant fixes (Denver requires repairs before reusing the chimney). 5. Re-test: They verify proper draw (smoke should vent upward) and zero CO leakage before you can relight. Cost note: Emergency sweeps in Aurora typically range from $150–$350, depending on creosote severity and repairs needed. See our transparent pricing. Warning: If your chimney has no liner, you’ll need a relining inspection, unlined flues are a major fire risk in Denver’s dry climate.
7. ‘I can’t afford an emergency sweep, what are my options?’ (Denver resources for low-income homeowners)
Chimney emergencies don’t wait for budgets. Here’s how Aurora residents can get help: - Denver County Health Department: Offers low-cost CO detector loans for families at risk.

Frequently Asked Questions
My Aurora home has a gas fireplace, do I still need an emergency chimney sweep?
Yes. Gas fireplaces still need annual inspections for venting blockages, cracked heat exchangers, or CO leaks, especially in Aurora’s older homes where masonry deterioration can trap exhaust. The EPA’s Burn Wise program recommends checking gas fireplace vents twice a year the EPA's Burn Wise program. If your gas fireplace smells like sulfur or backdrafts, call a sweep immediately, this signals a venting failure.
I found a dead bird in my chimney, is this an emergency?
Absolutely. Animal nests or debris block 30% of chimney fires in Denver the National Fire Protection Association (NFPA)|https://www.nfpa.org/)). A dead bird means larger animals (like raccoons) may have nested there, creating a fire hazard and CO risk. Do not remove it yourself, call an emergency sweep to safely clear the flue and inspect for damaged liners or creosote buildup. See how to spot animal blockages.
My chimney passed inspection last year, why is there smoke in my house now?
Smoke backing into your home after a clean sweep usually means one of three problems: 1. Negative house pressure (from a sealed home or strong winds near Aurora’s plains). 2. A cracked or collapsed flue liner (common in older brick chimneys). 3. A blocked or improperly sized chimney cap. Solution: Have a sweep perform a smoke test to diagnose the issue. Never use the fireplace if smoke enters the room, this is a direct CO risk. Learn how to test your chimney’s draw.
How much does an emergency chimney sweep cost in Aurora, and does insurance cover it?
Emergency sweeps in Aurora cost $150–$350, depending on creosote severity and repairs. Most homeowners’ insurance policies do not cover routine chimney maintenance, but some may reimburse emergency repairs if the damage was caused by a covered peril (like a storm cracking your crown). Document the issue with photos and call your insurer before hiring a sweep. See our cost guide for Aurora.
