The passage carrying combustion products out — one appliance, one flue, correctly sized.
The interior channel of the chimney. Its cross-sectional area has to match what the appliance produces: oversized runs cool the gases and increase deposit, undersized cannot carry the volume and spills. Connecting two appliances to one flue is a defect in most residential configurations, not a space-saving choice.
We work on flue 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.
