Chimney Odor Problems
A chimney that smells — smoky, musty, or worse — is telling you something. We find the cause and clear it.
Chimney odors aren't just unpleasant; they're a symptom. A smoky smell usually means creosote buildup. A musty, damp smell points to moisture getting in. A foul, rotting smell can mean an animal has gotten into the flue. Masking the odor with a candle doesn't fix any of these — it just delays the diagnosis.
Frank & Sons finds the source of the smell and eliminates it. Because different odors point to different problems, identifying the cause is half the job — and it often reveals an issue (a blockage, a leak, an animal) that needed attention anyway.
What different odors mean
- Smoky, tar-like smell — creosote buildup in the flue.
- Musty, damp smell — moisture entering the chimney.
- Rotting or foul smell — an animal or nest in the flue.
- Odors that worsen in summer humidity or after rain.
- Smells that push into the room on downdrafts.
How we clear it
We inspect to determine which cause is at work. If it's creosote, a thorough cleaning removes the odor-causing buildup. If it's moisture, we track down and fix the water entry — often a missing cap or a crown/flashing leak — then address the dampness. If it's an animal, we handle removal and seal the entry point.
Because odors frequently ride into the room on downdrafts, we also look at draft and cap conditions. Fixing the underlying cause — rather than perfuming the symptom — is what keeps the smell from coming back.
Why it matters in Greater Pittsburgh
Pittsburgh's humid summers are prime time for chimney odors: warm, damp air moving down an uncapped or leaking flue picks up the smell of accumulated creosote and pushes it into the house. A proper cap and a clean flue solve the most common version of this complaint.

Frequently Asked Questions
Humidity and downdrafts. Warm, moist air moving down the flue amplifies creosote odors and pushes them into the room. It's one of the most common seasonal complaints we hear.
Often, yes. A cap keeps out rain and animals — two major odor sources — and reduces downdrafts that push smells inside. It's frequently part of the solution.
Yes. We remove the animal or nest, clean and deodorize the flue, and seal the entry point so it doesn't happen again. See our animal removal service.
