Cracked brick over the garage door can be fixed most often, depending on the severity of the crack or the exact cause of it. In time, the bricks over the garage door can crack due to water, pressure, or heavy impact. Before the damage gets even worse, make sure to repair the crack as soon as possible.

Step 1 – Determine the Cause of the Crack

The usual cause of a cracked brick over a garage door is a sagging lintel. The lintel can sag downwards towards the center due to improper installation or heavy pressure. Check the lintel to see if it has any signs of damage or corrosion. If the sag is too much, then it is probably best to let a professional engineer take a look at the damage and suggest solutions.

Sometimes, the crack may be due to the weather. Rain and sunlight can cause the bricks to crack or even crumble. If the brick has crumbled, it is best to replace it with a new one. If the brick only has narrow cracks, but is still intact, it can be repaired without removing anything except for the mortar around it. Replacing the mortar can ensure that the crack does not get worse.

Step 2 – Removing the Old Brick

Finding a replacement brick can be very tricky especially if the brick is very old. To make sure that the new brick matches the surrounding brick work, take a photograph of the bricks over the garage door and go to a brick supply store. Let them find a suitable brick that has the best match in texture and color.

Wear safety glasses, a respirator and safety gloves. To remove the brick, position the plugging chisel over the mortar and mash hammer it to remove all the mortar around the brick. Remove the cracked brick in the same fashion. Remove the brick pieces from the cavity and dust off the remaining residue.

Step 3 – Setting the New Brick in Place

Mix the brick mortar according to the manufacturer’s instructions in a container. Before applying it to the empty cavity, dampen the hole first with water. Apply the mortar on the bottom of the cavity and on its sides. Dampen the new brick with water and insert it through the hole carefully. Use a trowel to remove any of the excess mortar. Smooth the new joints with a wheel rake to let the new mortar match the existing joints. Allow the mortar to cure.

In some instances, it may be necessary to purchase color stain sprays to allow the new brick to match the old bricks. If there are too many bricks to color, consider hiring a color specialist to do the job. In addition, never attempt to repair the lintel on your own as this may damage the other bricks. Call for professional help when necessary.
