How to Install a Dryer Vent in a Wall

Whether you have moved to a new home or relocated the dryer in your current home, you must install a dryer vent. Installing a new dryer vent in a wall is not difficult with a little planning. First, purchase a dryer vent from the hardware store. Next, drill a hole in the wall and hook the duct work to the vent and the dryer. The entire project will take an hour to complete on average.

  1. Determine where you will install the dryer vent. Position the dryer as close to an exterior wall as possible. Ideally, you want as short a route as possible for your exhaust duct. Once you have determined the approximate location of the vent, go outside and check for obstructions. You need 12 inches around the outside vent to be free of any obstructions.

  2. Go inside and drill a hole 12 inches from the floor where you are installing the vent. Drill only through the inner wall using a 1/8-inch drill bit. Untwist a metal clothes hanger and bend 6 inches of the hanger 90 degrees. Insert the bent piece of the hanger into the wall and rotate the hanger all the way around to check for obstructions such as electrical wires.

  3. Drill through the wall with a long ¼-inch bit once you know there are no obstructions. Drill all the way through to the outside wall. Insert a 4-inch hole saw into the drill and drill a hole from your pilot hole on the inside wall. Take the drill outside and drill the hole from the outside at the pilot hole in the wall.

  4. Insert the pipe end of the dryer vent into the wall and press the face of the dryer vent flush against the wall. Mark the mounting holes to the wall with a pencil. Pull the dryer vent out of the wall and set the vent aside. Drill pilot holes at the pencil marks for your mounting screws.

  5. Set the dryer vent back into the wall and secure the vent to the wall using the supplied mounting screws and a Phillips-head screwdriver. Apply a bead of silicone caulk around the perimeter of the dryer vent with a caulking gun. Also apply a small amount of caulk around the heads of the mounting screws.

  6. Go inside and connect the dryer duct to the dryer vent and the dryer exhaust using the supplied clamps. Tighten the clamps with a Phillips-head screwdriver.


  • Always check the inside of the wall for electrical wires before installing vents. Accidentally cutting through wires can cause injury and even death.
