Dryer Vent Repair and Rerouting in West Palm Beach
Most repairs: $150 to $400
Cleaning a vent that is kinked, disconnected in the attic or made of plastic is a temporary fix at best. Homes across Palm Beach County commonly put the laundry in an interior closet or the garage and run the dryer vent up through the attic to a roof or soffit cap, and condo vents can run 25 feet or more through the building with several elbows, close to the 35-foot code limit. Those long runs clog first and come apart where nobody can see them. When the run itself is the problem, it gets repaired or rebuilt.
Common problems we fix
- Disconnected joints in the attic that have been blowing lint onto the insulation for years. Reconnected with rigid duct and foil tape, never screws, which catch lint.
- Plastic or foil flex inside walls and attics, which melts and traps lint. Replaced with rigid metal duct.
- Crushed transition hose behind the dryer. Replaced with a semi-rigid connector and a periscope fitting where the dryer sits tight to the wall.
- Runs that exceed code length for the number of turns, which no amount of cleaning fixes. Rerouted to a shorter path or fitted with a listed dryer exhaust duct power ventilator.
- Failed or screened exterior caps that clog, let in birds, or will not close. Replaced with a proper damper cap.
- Roof terminations that have rusted through or were installed with a screened cap.
Power ventilators for long runs
Generic inline booster fans are not allowed in a dryer duct under the residential code. When a run cannot be shortened, the fix is a dryer exhaust duct power ventilator listed for that use, installed to its instructions with a pressure switch and an access point for cleaning the fan itself.
Code
Florida writes one building code for the whole state, and the Florida Building Code, Residential, 8th edition (2023), in force in every Palm Beach County city, caps a dryer exhaust duct at 35 feet, deducting 5 feet for every tight mitered 90-degree elbow and under 2 feet for a smooth long-radius one. It requires smooth metal duct of at least 28 gauge, no screws joining the sections, a backdraft damper at the termination and no screen on it. The 9th edition takes over on December 31, 2026. Every repair we do meets it, and we leave you a written description of what was changed.
