For active chimney fires or gas emergencies — call 911 first.

After emergency services have cleared the scene, call Widen Chicago at (224) 343-1991 for a certified post-emergency inspection before using your fireplace again.

What Counts as a Chimney Emergency?

Not every chimney problem needs same-day service — but these do:

Active or recent chimney fire
Even if it appears to have gone out, a chimney fire may have cracked your flue liner and spread heat to adjacent framing. Do not use the fireplace. Call immediately.
Carbon monoxide detector alarm while using fireplace
Evacuate the home and call 911. A blocked or damaged flue can force CO into living spaces. Do not re-enter until cleared and inspected.
Storm damage — falling bricks, displaced cap, visible cracks
Chicago storms can shift or collapse chimney tops. Loose masonry is a structural hazard. We tarp and stabilize the same day.
Smoke entering the home through the fireplace
Sudden backdrafting can indicate a blocked flue, collapsed liner, or animal intrusion. We clear blockages and inspect the flue the same day.
Visible chimney leaning or separation from house
A chimney pulling away from the exterior wall is a structural failure. Do not use the fireplace. We assess and stabilize before any further damage occurs.

What Happens After a Chimney Fire

A chimney fire burns at temperatures up to 2,000°F — hot enough to crack flue tiles, warp dampers, and ignite the wood framing around the chimney. Many chimney fires go undetected because they burn inside the flue without any visible smoke or flame from outside.

After any chimney fire — even a small one — you need a Level 2 inspection with HD camera before using the fireplace again. Our certified technicians document the damage, provide an insurance-compatible photo report, and give you a clear repair plan. Most homeowners insurance policies cover chimney fire damage; we help you build the documentation your claim requires.

Insurance Documentation After a Chimney Emergency

Chimney fires, storm damage, and structural failures are typically covered by homeowners insurance — but your insurer will require a professional assessment and documentation. Our post-emergency inspections include an HD camera report, annotated photos of all damage found, a written scope of repairs with itemized costs, and certification of the chimney's current safety status. This documentation is formatted to work directly with insurance adjusters and is accepted by major Illinois insurers. If your adjuster has questions about our findings, we are available for follow-up calls.

What to Do While Waiting for an Emergency Technician

Stop using the fireplace immediately. Close the damper to reduce airflow. Do not attempt to clean or inspect the flue yourself — the inside of a chimney after a fire or storm is a hazard environment with unstable debris and potential CO exposure.

Document what you can see safely. Take photos of any visible exterior damage — shifted bricks, missing cap, cracked crown — from the ground. If there is loose masonry, keep people away from the area below. These photos are useful for your insurance claim.

Ventilate if you smell smoke. Open windows and doors. If you smell gas, leave the home immediately and call your gas utility's emergency line before calling us.

Do not tarp the chimney yourself. An improperly placed tarp can trap moisture inside the chimney and make damage assessment more difficult. We tarp correctly and know what to avoid covering during the inspection.

Carbon Monoxide: The Silent Emergency

Carbon monoxide is colorless and odorless — you cannot detect it without a CO detector. Every home with a fireplace, furnace, or gas appliance should have CO detectors on every floor. If your detector triggers during fireplace use: close the damper, leave the home, call 911, and do not re-enter until emergency services have cleared the scene. Then call Widen Chicago for a certified inspection before the fireplace is used again. Common causes of CO entry include blocked flues (bird nests, debris, collapsed tile), cracked flue liners that allow combustion gas to leak into walls, and negative pressure conditions that reverse chimney draft. Our post-CO inspection identifies the exact cause and provides a fix — not just a clearance.

Chicago Weather and Emergency Chimney Risks

Chicago's severe weather creates specific chimney emergencies that we respond to regularly: high-wind events that dislodge or blow off chimney caps and damage crowns, ice storms that add hundreds of pounds of ice to chimney tops and crack mortar, and freeze-thaw cycles that can cause rapid structural deterioration in already-compromised chimneys. After any major Chicago storm — especially wind events, ice storms, and heavy snowfall — visually inspect your chimney exterior from the ground. If anything looks shifted, missing, or cracked, call for an inspection before lighting your next fire.

Frequently Asked Questions

What counts as a chimney emergency?
A chimney emergency is any situation that poses an immediate safety risk: a chimney fire (roaring noise, dense smoke, intense heat), carbon monoxide symptoms (headache, nausea, dizziness when fireplace is in use), a chimney collapse or partial collapse, severe storm damage to the chimney crown or cap, or sudden smoke backdrafting into your home that cannot be stopped by closing the damper.
What should I do if I have a chimney fire?
Call 911 immediately. Close the damper to cut off oxygen to the fire. Do not pour water into the fireplace. Evacuate your home. Once the fire department clears the scene, do not use the fireplace until a certified chimney sweep performs a Level 2 inspection. Chimney fires often damage the flue liner in ways that are invisible but create serious CO and re-ignition hazards.
How quickly can you respond to a chimney emergency in Chicago?
Widen Chicago prioritizes emergency calls. In most cases, we can respond within 24 hours for urgent situations. For active chimney fires, call 911 first — we handle the post-fire inspection and repair. Call us at (224) 343-1991 for emergency scheduling.
Can I use my fireplace after storm damage to my chimney?
No. Stop using the fireplace immediately if you notice missing mortar, a damaged or missing cap, shifted chimney structure, water in the firebox, or debris inside the flue after a storm. These conditions create fire and carbon monoxide hazards. Call for an emergency inspection before resuming use.
How much does emergency chimney repair cost?
Emergency chimney service calls start at $199 for an after-hours inspection. Repairs are quoted on-site based on scope. Cap replacement runs $200–$500. Emergency crown repair or tarping runs $300–$700. Structural emergency repairs requiring scaffolding or immediate rebuilding are quoted after inspection.
Is it safe to use a fireplace with carbon monoxide detector alarms?
No. If your CO detector triggers during fireplace use, close the damper, leave the house, get fresh air, and call 911. Once cleared, call a chimney professional before using the fireplace again. CO entry is almost always caused by a blocked or damaged flue, cracked liner, or closed damper. This is a medical emergency, not a troubleshooting opportunity.
