  1. 1

    Determine where the window will go, measure the size of the window and mark the dimensions on the outside of the house with a chalk line around the perimeter. Attach a masonry blade to a circular saw and make sure the depth of the blade is 1/2 inch. Cut along the chalk lines around the perimeter of the opening.

  2. 2

    Adjust the saw's depth to 1 inch and repeat the same process. Continue adding 1/2 inch to the depth until the blade goes completely through the bricks. Tap the bricks with a masonry hammer to begin removing them. Take out the first brick and continue until all the bricks have been removed.

  3. 3

    Clean around the outside opening to remove any leftover debris. Sweep out the bottom of the opening with a masonry brush and ensure that all of the debris has been removed.

  4. 4

    Cut with a 2x4 piece of lumber, using a circular saw and wood blade, to fit along the sides and top of the window. This will act as the frame. Drill the boards into the brick on both sides and the top with masonry screws and a drill.

  5. 5

    Set the window into the opening and use a level to check whether it is plumb and square. Insert shims between the edge of the window and the frame if it needs to be levelled out. Screw the window to the wooden frame along the sides. Insert a screw every 12 inches through each side of the window to secure it to the frame.

  6. 6

    Caulk the gap between the jamb of the window and the frame on both sides. Run a bead of caulk up the gap on each side to seal any gaps. Give the caulk time to dry before moving on.

  7. 7

    Install the exterior trim around the window with nails and a nail gun. Insert a nail every 6 inches around the trim and repeat the process using the desired trim for the interior of the window.

Tips and warnings

  • Always use safety goggles and a dust mask to prevent injury when cutting through brick.
