Exterior vent repair cost
Fixing stuck, damaged, loose and uncovered vents on the outside of the house.
Bathroom fans, kitchen hoods and dryers vent through openings on the outside walls or roof. Each opening should have a flap or grate that closes when the fan is off.
A vent that's stuck open or missing its grate lets in insects, birds and rodents. Most of these are quick fixes.

What affects the price
- How many vents
- Several vents fixed in one visit cost less than separate trips.
- Height
- Vents high on a wall or on the roof need ladders and take more time.
- Type of vent
- Dryer vents need a hood with a flap, not a screen, because screens catch lint.
