How to Mount a Dryer Vent on a Brick Wall

A short and straight dryer vent that mounts to an exterior brick wall collects less lint than a dryer vent using 90-degree fittings to reach and penetrate the roof. Lint build-up creates a fire hazard and reduces the dryer's efficiency. Wall-mount dryer vents have three parts: a louvered cap, a 4-inch-diameter metal pipe and an interior trim ring. The louvered caps prevent wind and water from entering the home. The dryer's flexible tube connects to the vent's 4-inch pipe, and the trim ring covers the hole in the interior wall.

Instructions

  1. 1

    Lay out the dryer vent's hole on the interior wall. Measure 8 inches up from the floor with a tape measure, and make a pencil mark on the wall. Hold the vent's 4-inch pipe against the wall with its bottom on the pencil mark. Trace the outline of the pipe with the pencil.

  2. 2

    Poke a hole in the centre of the circle drawn on the wall with a flathead screwdriver. Probe inside of the wall with the screwdriver. Feel for studs. If the screwdriver's end hits a stud, then adjust the hole's placement accordingly.

  3. 3

    Cut the circle drawn on the wall with a drywall saw. Remove the drywall cutout.

  4. 4

    Equip a drill with a 1/4-inch masonry drill bit. Position the drill bit in the centre of the drywall hole and drill a hole through the brick wall. Masonry drill bits have a straight-edged triangle-shaped tip and use a slightly thinner shaft.

  5. 5

    Lay out the dryer vent's hole on the exterior of the brick wall using the hole drilled from inside of the house as a placement guide. Make a pencil mark 2 inches from the drilled hole horizontally and vertically. Align the dryer vent's pipe with these two pencil marks, and trace the pipe's outline with the pencil.

  6. 6

    Draw a second circle on the brick wall 1/2-inch larger than the pipe's outline. The second circle should have a 5-inch diameter.

  7. 7

    Drill a series of holes every 1/2 inch along the larger circle with the masonry drill bit. Drill a hole in every mortar joint.

  8. 8

    Remove the brick from the circle with a chisel and hammer. Hold the chisel between the drilled holes and strike its handle with the hammer. The brick will break between the drilled holes.

  9. 9

    Slide the vent into the hole until the louvre sits flush with the brick wall. Mark the louvre's mounting holes on the brick with the pencil.

  10. 10

    Remove the vent from the brick wall. Drill the mounting holes in the brick with the 1/4-inch masonry drill bit. If local building codes require a 5-inch diameter sleeve, then slide the sleeve into the hole from the exterior wall. Seal the sleeve to the brick with exterior-grade caulk.

  11. 11

    Run a bead of exterior-grade caulk around the inside edge of the louvre. Push the dryer vent into the hole or sleeve. Press the louvre against the brick, then fill any mortar joint gaps with the exterior caulk.

  12. 12

    Secure the louvre to the wall with the manufacturer-recommended anchors, usually concrete screws. Slide the anchor through the louvre's mounting hole into the brick, and tighten the anchor.

  13. 13

    Fill the space between the vent's pipe and the brick hole or 5-inch sleeve with a non-expanding foam through the interior wall.

  14. 14

    Apply a bead of caulk around the vent's trim ring. Slide the trim ring over the pipe and press it onto the drywall.
