Your Local Help for Chimney Odors
Smells from a fireplace almost always trace back to one of four things: creosote in the flue, water in the masonry, something that died or nested in the chimney, or air being pulled down the flue into the house. Candles and sprays only cover it for a day. We find which one it is and deal with the cause, so the room stops smelling like an old campfire.
About Chimney Odor Removal
Fireplace odors nearly all trace back to four sources: creosote in the flue, water soaking the masonry, an animal or nest in the chimney, or air moving down the flue into the room. Each has its own signature. Creosote smells like a cold campfire or fresh asphalt. Wet masonry and soot together give a musty, basement smell. An animal leaves a sharp, sour or rotten odor. Air flowing down the flue carries whichever of those is present into the house.
Summer brings most of the calls. Humid air reactivates the smell of creosote left over from winter, and when the windows are shut and the air conditioning runs, the house can draw air down the chimney through a damper that does not seal well. Older homes with large open flues and rusted dampers are the usual suspects, but tight, newer homes with strong range hoods, bath fans and dryers can pull air down a flue just as hard.
Odor removal works by matching the fix to the source. Creosote comes out with a thorough sweep of the flue and smoke chamber. Nests and remains are cleared out and the flue is capped. Water entry gets traced and stopped. Air movement gets blocked with a damper that actually seals, often a top-sealing one. A deodorizer can follow as a final step, but on its own it only covers the smell for a while.
What Our Crew Does
- Questions about when the smell peaks: humidity, rain, fans running or certain rooms
- Smoke shelf, damper, smoke chamber and flue checked for deposits and debris
- Creosote swept out of the flue and scraped from the smoke chamber
- Nests, leaves and any animal remains removed and bagged
- Damper closed and checked for gaps along its seal
- Crown, cap and brick looked at for the water that feeds a musty smell
- The cause explained, with any repair beyond cleaning priced in writing
When to Call Us
- A tar-like smoky smell that gets stronger in summer
- A musty, basement-like smell near the fireplace
- The smell shows up when a bathroom fan or range hood runs
- A sharp animal smell from the firebox
- The room smells worse after a heavy rain
How the Job Goes
- Find the source
We ask when the smell is strongest, then look at the flue, the smoke shelf, the damper and the top of the chimney.
- Clean it out
Creosote is swept from the flue and smoke chamber, and any nest, leaves or animal remains come out.
- Stop the air flow
If air is coming down the flue, a better-sealing damper or a top-sealing damper keeps it out when the fireplace is not in use.
- Deal with water
If damp is behind the smell, we show you where water gets in and give you a free written estimate to stop it.
Your Options
The flue and smoke chamber cleaned first, then a treatment that neutralizes what is left in the masonry pores.
A damper with a gasket at the flue top that blocks air from coming down when the fireplace is idle.
Cut the air exchange between the room and the firebox, which reduces how much smell reaches the room.
Crown, cap, flashing or repellent work where damp masonry is behind the musty smell.
What Affects the Cost
- What is actually causing the smell
- How heavy the creosote is in the flue and smoke chamber
- Removing an animal, a nest or remains, and cleaning up after it
- Replacing a damper that no longer seals
- Repairs to stop water getting into the masonry
Every job starts with a free written estimate, so you know the price before we start.
When It Cannot Wait
- An exhaust smell near the boiler or water heater: open windows and check the carbon monoxide alarms
- A rotting animal smell coming from the firebox
- A musty smell with visible mold on walls beside the chimney
- Smoke smell in rooms far from the fireplace while it burns
Make It Last
- Book the sweep at the end of the burning season, not only before the next one
- Close the damper firmly once the fireplace is done for the year
- Keep a capped top so rain and animals stay out of the flue
- Crack a window when strong exhaust fans run in a tightly sealed house

How to Close Up a Fireplace for the SummerClosing a fireplace for summer takes four steps: let the last fire go completely cold, clear out the ash, shut the damper tight, and cover the opening if the damper leaks.
