Dryer Vent Cleaning and Replacement

Lint that builds up in the vent is a leading cause of home dryer fires. We clean the full run from the back of the dryer to the outside hood, and replace foil hoses or bad runs with smooth metal duct.

Signs you need this

  • Clothes need two cycles to dry
  • The dryer or laundry room gets unusually hot
  • A burning smell when the dryer runs
  • Lint collecting around the outside vent hood, or a flap that doesn't open
  • A foil or white vinyl accordion hose behind the dryer
  • It's been more than a year since the vent was cleaned

What’s included

  • Cleaning of the full vent run with rotary brushes and air
  • Lint trap housing and dryer connection cleaned
  • Outside hood cleared and damper checked
  • Airflow check before and after
  • Optional replacement with rigid or semi-rigid metal duct and a new hood

Why dryer vents matter

The U.S. Fire Administration lists failure to clean as the leading cause of home clothes dryer fires. Lint is extremely flammable, and a clogged vent traps heat inside the dryer. A clogged vent also forces the dryer to run longer, which wears out the heating element and costs you more in energy.

Cleaning the whole run

The lint screen only catches part of it. The rest collects in the vent, especially at bends, in long runs, and at the outside hood. We clean from end to end, clear the hood, and check airflow at the outside before and after.

When the vent needs replacing

Many vents we see are foil or vinyl accordion hose, too long, full of sharp bends, or disconnected inside a wall or ceiling. We replace them with smooth metal duct on the shortest practical route, seal the joints with foil tape rather than screws that catch lint, and install a proper hood with a working damper.

Common questions

How often should a dryer vent be cleaned?

Once a year for most households. Large families, long vent runs, or vents that go up through the roof may need it more often.

Why replace the foil or plastic hose?

Accordion hoses trap lint in their ridges, crush easily behind the dryer, and vinyl can melt. Building codes call for smooth metal exhaust duct, with only a short, listed transition hose at the dryer.

My vent goes out through the roof. Can you clean it?

Yes. Roof vents clog faster because lint has to travel up. We clean them from inside and outside as needed and check that the roof cap isn't screened, since screens catch lint.
