Step 4: Create a Frame for the Garage Door

Construct a frame for the garage door using pressure-treated wood. The frame should have the same dimensions as the cut wall to ensure a perfect fit. Remember to use a level while building the frame to ensure accuracy.

Step 5: Attach the Frame

Attach the frame to the wall opening using masonry nails or anchors. Ensure the frame is level, secure, and flush with the wall surface.

Step 6: Install Lintel

Insert a precast or custom-made lintel above the garage door frame to support the weight of the wall. It is important to follow the manufacturer’s recommendations for installing a lintel.

Step 7: Reinforce with Rebar

Insert rebar in the lintel, extending beyond the wall opening on both sides. This is to reinforce the lintel’s support for the weight of the wall above the garage door.

Step 8: Pour Concrete

Prepare the concrete mix and pour it behind the frame and around the rebar. Ensure the concrete fills between the wall opening and the lintel and levels with the wall surface.

Step 9: Install Garage Door Track

Attach the garage door track along the frame’s top edge using connectors. Ensure the track aligns with the garage door’s edge for smooth opening and closing.

Step 10: Install Garage Door

Finally, install the garage door following the manufacturer’s instructions. Ensure it has proper balance, maintenance, and security features, such as locks and sensors, to prevent accidents.
