Chimney & Fireplace
Smoke coming into the room, or a strong odor from the chimney
Likely cause, what to safely try first, and whether it gets worse if you wait.
Likely cause
A blocked flue (creosote, debris, or an animal nest) or a damper issue.
What to try first
- Stop using the fireplace immediately and ensure the area is ventilated — this can be a carbon monoxide risk.
- Check that the damper is fully open before assuming it's a blockage.
⚠ This tends to get worse (and more expensive) the longer it's left unaddressed — worth acting on soon.
