A dryer vent hood addresses the hot air and lint from the dryer duct as it leaves the house. The hoods might turn cracked or broken, and need to be substituted periodically.

Polish off the Old Hood
Dryer vent hoods are normally associated to the exterior wall of the house. Ascertain the old hood for the character by screw that was applied in it is installing, and then apply the suited screwdriver to remove the screws. The hood may still be inhered in the wall of the house because of sealant or calking applied to cover any cracks. Apply a utility knife to cut through the sealant and remove the hood.

Come off from Dryer Duct
The hood may be accompanied the dryer duct inside the wall with a clamp or metal duct tape. Take out the clamp or tape and free the old hood from the interior duct-work.

Taping or Clamp New Hood
Inside the wall, attach the new duct hood to the interior dryer duct with the clamp or tape recommended by the manufacturer.

Bond Hood to Exterior Wall
Applying screws (generally provided in the duct hood kit), attach the new hood to the exterior wall where you removed the old one. Use a silicone caulk/sealant around the joint to closing whatever gaps and stop any air escape.
