We replace flimsy plastic vent caps with heavy steel ones that birds, squirrels, and rodents can't get through. One install, built to last for the life of your home.
Steel. Not plastic.
A warm dryer vent is the perfect place for a nest. Plastic louvered caps fade, crack, and stick open in the sun, and that's all the invitation birds, squirrels, and mice need. A nest blocks airflow, which makes your dryer work harder and raises the fire risk.
A clean, low-profile steel cap that looks better and keeps working for years.


Both are made in the USA by InOvate, the company behind the Dryerbox. We'll recommend the right one for your vent when we're there.


A sleek steel cap that sits close to the wall. Comes in white, tan, brown, or black to match your house.

A tough steel hood with a row of steel bars underneath. Animals can't get in, but lint can still get out.
Why not just a screen? Screens on dryer vents catch lint and clog fast, and building codes don't allow them on dryer exhaust. Both of these caps keep animals out without a screen.

A one-time upgrade, built to last.
$200–$225 installed. These are premium steel caps, not plastic, so it's a one-time upgrade that's built to last for the life of your home.
No. The DryerWallVent uses a lightweight damper that swings wide open, and The Defender uses open steel bars instead of a screen. Both let air and lint out while keeping animals out.
Yes. We clear the nest and debris, clean the vent run, and then install the new cap so it doesn't happen again. See dryer vent cleaning.
Screens trap lint and clog quickly, which blocks airflow and creates a fire risk. Building codes don't allow screens on dryer exhaust vents. Our steel caps keep animals out without one.
