You've just purchased your first dryer for your home, or maybe you decided the current location for the dryer just is not working. With either of these scenarios, you will likely need to drill a new hole through the exterior of your home for the dryer vent piping. Since dryer vent piping is 4 inches in diameter, you will need a fairly large hole. If the exterior of your home is brick, you are up for a bit of a challenge.

Instructions

  1. 1

    Decide where you want the dryer vent to penetrate your outside wall. Go outside and lay out the centre of the desired area. Use a reference point, such as a window, to transfer the measurements from inside the home to outside. Drill a 1/4-inch hole with a power drill at this location all the way through the wall.

  2. 2

    Go inside your home and check to see that the location matches up with where you planned the hole in Step 1. Remember, a 4-inch pipe will be penetrating this location, and you want enough room to accommodate it. A small hole is much easier to patch than a large one if you inadvertently drill in the wrong location.

  3. 3

    Draw a 4 1/4-inch circle on the exterior brick with a compass using the drilled hole as the centre.

  4. 4

    Drill through the brick on the line made with the compass. Do this around the entire circle. Drill completely through the brick and space the holes about 1/2- to 3/4-inch from each other.

  5. 5

    Place a chisel up against the circle at a 90-degree angle. Strike the chisel with a 2-pound sledgehammer. Work your way around the circle. The brick will begin to chip out and break between each drilled hole.

  6. 6

    Clean up the hole with the hammer and chisel once the majority of the brick loosens up from the wall. What you should have left is a nearly circular 4 1/4-inch hole. It does not need to be perfect as the dryer vent cap will cover the imperfections.

  7. 7

    Go inside your home and drill through any drywall, wood or other wall material with a 4 1/4-inch hole saw. Use the pilot hole you drilled in Step 1 as your centre. Once this material is removed, you will have a clean hole for installing the dryer vent.

Tips and warnings

  • Wear appropriate safety gear when drilling through brick. Safety glasses and ear plugs are a necessity to prevent damage to your eyes and ears.
