Wall & Ground-Level Dryer Vents

Walk around the exterior of the house on the same side as your laundry room and look for a 4-inch hooded cap with a flap, usually 1–4 feet above the ground for basement laundry or at second-floor height for upstairs laundry. Run the dryer and look for the flap moving or feel for warm air.

Yes if the bushes touch the cap. Shrubs trap lint, block the flapper, and in winter hold snow against the opening. Keep 12 inches of clearance so the flap swings freely.

No. Building code prohibits screens on dryer exhaust terminations because they trap lint. If your cap has a screen we remove it and recommend a louvered or pest-guard cap designed for dryers.

The flapper is the hinged door on the exterior cap. It opens from airflow when the dryer runs and closes to keep cold air and pests out. A stuck or broken flapper either leaks cold air into your house or blocks exhaust.

Yes. Drifting snow against a low wall vent blocks the flapper and forces exhaust back into the duct. After big snowfalls, clear 12 inches around the cap. We also install vent extensions that raise the outlet above typical drift height.

The exterior flapper is stuck open or missing, letting outside air flow backward down the duct. We replace damaged caps so the flap seals when the dryer is off.

Yes. Wall and ground-level vents are $139 because we reach the cap from the ground or a short ladder and clean the full run from inside. Roof vents are $199.

No. Dryer exhaust must terminate outdoors. Venting into a garage, attic, or crawl space creates moisture, mold, and a lint fire hazard, and for gas dryers it dumps combustion gases indoors. We can advise on correct termination.

Not for a gas dryer, ever. For electric dryers they are a last resort for apartments with no exterior access and they dump warm moist air and fine lint into the room. A proper exterior vent is always better.
