White residue or corrosion around exhaust joints needs same-day attention. In older Bowie homes, we sometimes find exhaust pipes that were never properly sealed to begin with. ## Our Furnace Exhaust Repair Process We inspect the entire exhaust path from the furnace to the exterior vent. We check for blockages. bird nests, leaves, ice buildup. as well as cracks, rust-through, disconnections, and improper slope. We repair or replace damaged sections, seal all joints with proper materials, and test for correct draft using combustion analysis equipment. We verify with CO testing at the furnace and throughout your home that no combustion gases are entering your living spaces. ## Furnace Exhaust Repair Cost in Bowie Costs depend on the extent of damage and pipe length. Simple resealing is very affordable. Replacing a full exhaust run costs more. We provide an upfront quote.
