Flow reversal — products entering the room instead of leaving.
Occurs when the flue's draft is overcome, commonly by negative pressure in the house from exhaust equipment, or by wind at the termination, or by a flue too short or too cold. It is a safety finding, not a comfort complaint, because what comes back down includes combustion products.
We work on backdraft every week across DFW. CSIA-certified, written quotes, financing available.
Flat fee confirmed when you book. Same-week scheduling. A pass/fail verdict within 48 hours.
Chimney fire, storm hit, active leak, or a flue you're not sure about? We answer 7 AM to midnight and the assessment ends in a written safe-to-use verdict — including a do-not-use notice when the evidence supports one. After-hours dispatch runs subject to crew availability.
