A smoky, sour smell from the fireplace in summer?
- The smell shows up on humid days, strongest with the AC running
- Worse after rain; gone in dry spells
- The fireplace has not been used in months
Why it happens in Red Bank: This is Red Bank's signature chimney complaint, and it has two different causes that get sold the same fix. Usually it is creosote left in the flue reactivating with humidity. A cleaning genuinely solves that. But in tighter modern houses, air conditioning can pull air down the flue instead of up, carrying the smell of even a clean chimney into the room. Sweeping a clean flue a second time fixes nothing, and paying twice for it is the local racket worth knowing about.
What fixes it, and what it costs
First a sweep if the flue actually needs one. The camera scan says so honestly. If the flue is clean and the smell persists, the fix is airflow, not soap: a top-sealing damper that closes the flue when idle, and sorting how the house draws its makeup air. We tell you which case you are before we quote, because they cost very different amounts.
- Standard single flue, wood-burning
- $170–$320
- Gas appliance venting check
- $120–$220
