Are cracks in brick normal?

Brick walls with small cracks are common and typically harmless. However, large brick cracks in the exterior of your house can indicate a foundation issue.

What causes brick to crack?

Since most bricks are laid within a few weeks of being fired, they are still very dry and at their smallest size. As they absorb moisture, they expand. A foot-long brick can easily expand by half an inch. This means that the whole wall will be growing in size, leading to cracks.

Can broken bricks be damaged?

Why brick cracks

Masonry structures crack for several reasons. The first is because the footing or slab the masonry rests on moves. (Many older houses don’t even have what we’d consider footings today; the structural brick wall rests directly on the soil.) The first building material is not the footing but the soil that it bears on.

Sizing up the job

When people call me to repair brickwork, my first task is to look closely at the area in question and decide whether the work is going to be cost-effective or even feasible. In general, I encounter three types of problems. The first is old mortar that’s loose in spots and has some visible fissures and voids.

Use the right mortar

Mortar should be softer than the bricks so that small stresses are absorbed by the mortar rather than damaging the bricks. Before the late 19th century, mortar was very soft, consisting of lime and sand, and worked well with the soft bricks of the time.

Clean out the old mortar

The first step in repairing a crack is to grind out the old mortar. Joints should be ground to a depth that’s twice their width (usually 3⁄4 in. to 1 in.). The tools I use depend on the hardness of the mortar and the bricks as well as the overall integrity of the wall.

Make the mud to match

A common mistake is mismatching the mortar color. Achieving a perfect match is hard; old mortar can display a range of shades, and sometimes it was dyed. Prior to the 1960s, portland-cement/lime mortars prevailed and tended to be light tan in color.

Fill the joints

To transfer the mud from the hawk to the wall, I use tuck pointers in several widths (1⁄4 in., 3⁄8 in., 1⁄2 in., 5⁄8 in., and 3⁄4 in.), choosing the widest that will fit in the joint I’m filling. When possible, I work directly from the hawk.

Finish the joints

It’s as important to match the profile of the repaired joints with those on the rest of house as it is to match the color. Mortar joints can be finished in several ways.

How to match a brick?

1. Use the removed brick to find a color and size match. If the damaged brick came out in one piece, use it to find a color, style, and size match. If you only have broken pieces, use those for a color match but also write down the length, width, and height measurements of one of the remaining bricks in the wall.

How many bricks can you put in a mortar bag?
