A step-by-step process to replacing the door and installing a sliding:

 

1. Take off the door-opener mechanism, including the tracks, chains, and motor.

2. Remove the current garage door – To dismantle the door, unscrew the panels individually, working from the top to the bottom. Leave the structural framing in place, to support the load.

3. Construct a secondary wall on the inside of the framed opening – This defines the rough opening, houses your new door, provides a place that surrounds the sides of the new door, a surface for nailing wallboard and sheathing.

4. Decide where you are placing your new door – Take some measurements, centering the door in the opening. Use a chalk line on the floor to guide where you’re going to place the door.

5. Build a frame around the door – Build a sill plate, and a bottom plate. Place studs in the middle, roughly 40cm apart. Ensure you build plumb and square, ensuring no studs are bowed.

6. Anchor the Wall – Use concrete screws to secure the walls’ sill plate to the slab.

7. Install Insulation – Nail rigid sheets of foam insulation with a moisture barrier over the face of the frame. This helps to protect the door from moisture.

8. Fasten the Top Plate – Cut the plate, which will lengthen the opening and let you place studs on each side of the door, fastening it to the ceiling joists.

9. Start Placing the Door – Apply beads of sealant across the bottom of the opening.

10. Finish Placing the Door – Now insert the door from the outside (this will require at least 2 people). Do not slide it into place as this will mess up the sealant beads. Rather, tilt it into place, then making any adjustments.

11. Frame the Sides – Place studs, cut to fit in the middle of the sill and the top plate, which will frame the sides of the rough opening.

12. Nail and Screw – Hammer 1 x 10d finish nail or 3-inch screws into the middle section of each hinge jamb, amongst the framing studs.

13. Plumb and Square the Jamb – Use nails or screws to hold the door in place, and shims if necessary, between the jamb and the studs, and other areas if needed to square the opening.

14. Confirm Square – Measure the diagonals of the jamb corner-to-corner (X-patterned), checking they match.

15. Check to ensure the door opens and closes correctly.

16. Continue to fasten the jamb to the frame with nails and screws.

17. Add Finishing touches – All new doors need:

    • The edges and gaps insulated and sealed with spray foam and caulk.

    • Adhesive sealant applied to the bottom of the rough opening.

    • A coat of paint and some wall-mounted light fixtures.
