The pressure difference that moves combustion products up the flue.
Produced by the temperature difference between flue gases and outside air, and modified by stack height, flue area, terminations and the pressure of the house itself. When draft fails, the causes are enumerable — obstruction, proportion, height, or air supply — and they are distinguished by inspection rather than by guessing.
We work on draft 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.
