How to Install a Replacement Dryer Vent Hood


Dryer vent hoods prevent the heat, lint and carbon monoxide from the dryer from going directly into the windows. They are normally low to the ground and the hood keeps the air moving downward. Once blown out and down by the hood It dissipates and no longer is harmful. The hood is quick to install and replace since you already have your holes all drilled. Expect a 15 minute installation process.

Things You'll Need

  • New vent hood
  • Drill or screwdriver
  • Metal duct tape
  • Exterior silicone sealant
  • Unscrew the old vent hood from the outside. Use a utility knife to cut the sealant loose around the outside of the hood.

  • Access the joint where the hood pipe meets the rest of the piping to the dryer and peel off old metal tape. The hood should then be free to be pulled out of the wall.

  • Place the new hood pipe through the wall and go back to your access and tape the new hood pipe to the the rest of the vent piping.

  • Screw the hood to the exterior wall where you unscrew the old one. Put a bead of exterior silicone sealant around the joint between the hood and the wall. Allow the sealant to dry and check for any areas that did not get covered and add more sealant if there are any.

Tips & Warnings

  • It helps to have someone on the outside to pull the old hood pipe out and place the new one in while you're in the access area.
