7 Steps to Replace an Outside Dryer Vent Cover

Updated: Aug 6, 2023

Replacing an outside dryer vent cover can be an easy task, and you don't need to worry because it's quite affordable too. If your current cover is damaged or not working properly, it's essential to replace it to prevent potential issues like lint buildup or dryer fires.

Before starting the project, make sure you can access the existing dryer vent cover. Sometimes the vent goes through a crawlspace, which might make the job a bit tricky. If you find it challenging to access, you might consider seeking help from a professional dryer vent service company.

Here are the steps to replace the outside dryer vent cover:

  1. First, remove any old caulk around the existing vent cover by using a small putty knife. Be careful not to damage the external wall while doing this.

  2. Loosen the long mounting screws that hold the vent cover housing in place. Do it gradually, one screw at a time, to avoid damaging the screw holes. This will help you reuse the holes later.

  3. Gently pull the vent cover housing out of the opening. Sometimes it might be stuck in place, but with a little effort, you can remove it without causing any damage.

  4. Check for any issues in the hole and inspect the vent cover for damage or lint buildup that could cause problems with the new cover installation.

  5. Insert the new vent cover into the hole without bending the metal ducting connected to it. Once in place, press the new unit flat against the house and install any necessary insulation or weather stripping.

  6. Use the screws from the old vent cover to secure the new one in place. Tighten them evenly to ensure the unit is perpendicular to the house. Apply a bead of caulk along the outer edge to keep insects and weather out.

  7. Be cautious when handling the dryer vent cover assembly, as the metal ducting on the backside may have sharp edges. Wearing gloves is recommended.

Before finishing the replacement, turn on the dryer to ensure there's enough airflow coming through the vent. If you have a flapper-style cover and the flappers aren't fluttering, it means there might be an airflow issue. In such cases, the vent needs cleaning before completing the replacement.


Cleaning the dryer vent is essential to avoid lint buildup and prevent dryer fires. It also helps lower energy expenses and extends the life of your dryer.
