Emergency Chimney Service in Channahon, IL
When your chimney turns dangerous at 2 a.m., you need a clear head and a number that answers. Here is exactly what to do for the five chimney emergencies we respond to across Channahon, Minooka and Will & Grundy County — and when to call us.
A chimney emergency rarely announces itself politely. It shows up as a smell, a roar, a headache, or a chunk of brick in the flower bed. This page walks you through the five situations that send local homeowners reaching for the phone, with the real-world signs to watch for and the steps to take before help arrives. Read it now, while nothing is wrong — it is a lot harder to think clearly once a smoke detector is screaming.
Call 911 first if…
If you see active flames outside the firebox, smell gas, have a carbon monoxide alarm sounding, or anyone feels dizzy, nauseated or confused, call 911 before you call us. Get everyone out of the house first. Once you are safe and the immediate danger is handled, call Apex Chimney Service at (815) 364-8959 and we will take it from there.
1. A Chimney Fire
It is a cold Friday night in January. You loaded the stove with a couple of extra splits to beat the wind coming off the prairie, settled in… and then you hear it — a low roar, like a freight train, coming from somewhere inside the wall. Sparks are raining past the window.
That roar is creosote igniting inside the flue. A chimney fire can burn hotter than 2,000°F — hot enough to crack clay tiles and ignite the framing packed around the chimney.
Warning signs
- A loud roaring, rumbling or cracking sound from the chimney
- Dense smoke or showers of sparks shooting from the top of the chimney
- An intensely hot smell, or a glow from the firebox or flue
- Flames or glowing creosote visible through cracks or the cleanout door
What to do right now
- Get every person and pet out of the house immediately.
- Call 911 — a chimney fire can spread into the walls fast.
- If you can do it safely, close the stove’s air inlets or the fireplace damper to starve the fire of oxygen.
- Do not pour water down a hot flue — the steam can crack the liner and injure you.
- Once the fire is out and you have the all-clear, call us for a Level 2 inspection before you light another fire.
Why it is urgent: Even a fire that seems to burn itself out in a few minutes can leave the flue liner cracked and the clearances to combustible framing destroyed. The next fire you light could run straight into the structure. Call (815) 364-8959.
2. A Carbon Monoxide (CO) Leak
It is Sunday morning in a Minooka split-level. The gas fireplace ran all weekend to take the chill off, and now everyone in the house has a dull headache that will not quit. The baby is unusually sleepy. Then the CO alarm in the hallway starts to chirp.
Carbon monoxide is colorless and odorless. When a flue is blocked or a gas appliance vents poorly, CO backs up into the living space instead of going up the chimney.
Warning signs
- A CO alarm sounding — never ignore it, not even once
- Headache, dizziness, nausea or drowsiness that eases when you leave the house
- Soot or yellow-brown staining around a gas appliance
- A gas flame burning yellow or orange instead of crisp blue
- Heavy condensation on windows near the appliance
What to do right now
- Get everyone outside into fresh air at once — do not stop to open windows first.
- Call 911 from outside, especially if anyone feels ill.
- Do not go back inside until responders say it is safe.
- Shut off the gas appliance only if you can reach the valve without delay.
- Have the chimney and venting inspected before the appliance is used again — call us to find the blockage or venting fault.
Why it is urgent: CO poisoning can turn deadly in a matter of hours, and the symptoms are easy to mistake for the flu. The source is often a chimney problem — a blocked flue, a collapsed liner, or a nest — that only a proper inspection will reveal. Call (815) 364-8959.
3. A Severe Flue Blockage
First real fire of the season in your Channahon farmhouse. You open the damper, light the kindling… and the room fills with smoke in under a minute. Up on the roof, the chimney cap is packed with a summer’s worth of twigs where a pair of starlings decided to raise a family.
A blockage — an animal nest, fallen masonry, or a heavy creosote plug — leaves smoke and combustion gases nowhere to go but back into your home.
Warning signs
- Smoke pushing back into the room when you light a fire
- A strong, sharp smoky smell even from a small fire
- Scratching, chirping or rustling sounds inside the flue
- Debris, leaves or bits of masonry in the firebox
- A fire that will not stay lit or burns sluggishly
What to do right now
- Put the fire out and stop adding fuel.
- Open nearby windows and doors to clear the smoke.
- Do not keep relighting — you are only pushing more smoke and CO indoors.
- Leave the damper open so any trapped gases can rise.
- Call us to locate and clear the blockage before your next fire.
Why it is urgent: A blocked flue does not just make a mess — it forces carbon monoxide into the room and can hide a smoldering creosote fire. It will not clear itself. Call (815) 364-8959.
4. Smoke Backdrafting Into the Home
The wind is howling out of the northwest across the open fields toward Morris. Your fire was drawing fine an hour ago, but now every gust shoves a puff of smoke back down the chimney and into the family room. The detector by the stairs keeps threatening to go off.
Backdrafting happens when wind, air pressure, or a too-tight house overpowers the chimney’s draft and pulls smoke the wrong way — down instead of up.
Warning signs
- Smoke rolling out of the firebox into the room, often in gusts
- A smoky odor that lingers long after the fire is out
- Backdrafts that get worse when the furnace, range hood or dryer runs
- Cold air and odors pouring down the chimney on windy days
What to do right now
- Crack a window on the windward side of the room to give the fire makeup air.
- Turn off exhaust fans, the range hood and the clothes dryer, which all compete for air.
- If smoke keeps filling the room, put the fire out and ventilate.
- Check that the damper is fully open and nothing is capping the flue.
- Call us — chronic backdrafting points to a flue sizing, height or capping problem we can correct.
Why it is urgent: Every backdraft dumps smoke and carbon monoxide into your living space, and it is a sign your chimney is not venting the way it should. Call (815) 364-8959.
5. Sudden Structural Damage
A line of summer storms rolls up the Des Plaines valley and a gust takes a limb off the big silver maple. You hear the crack, and the next morning there is a scatter of bricks on the driveway and the chimney above the roofline is leaning like it has had one too many.
Storms, lightning, a settling foundation, or years of freeze-thaw can leave a chimney cracked, leaning or partly collapsed — and what is left can come down.
Warning signs
- Bricks, mortar or pieces of the crown on the ground or roof
- A chimney that is visibly leaning or pulling away from the house
- Large cracks running through the masonry
- Water suddenly staining the ceiling or wall near the chimney
- A tilted or damaged cap after a storm
What to do right now
- Keep everyone away from the area below the chimney, inside and out.
- Do not use the fireplace or any appliance that vents through it.
- If masonry fell on the roof or power lines are involved, call 911.
- Photograph the damage from a safe distance for your insurer.
- Call us to assess the structure and secure it before more comes down.
Why it is urgent: A compromised chimney is both a falling hazard and a fire hazard — cracks can let heat and embers reach framing you cannot see. It needs eyes on it quickly. Call (815) 364-8959.
