If your foundation has cracks wider than 1/4-inch wide, or if you have stairstep cracks in blocks or bricks, you can hire a contractor for foundation crack repair in Metro Detroit to plug them by injecting epoxy ($1,500-$3,000) or do it yourself with epoxy putty, but either way, you’ll only be stopping water from coming in.
You need to fix the underlying problem.
The most common culprit is water. It can accumulate in the soil around the foundation, which expands the soil and puts pressure on walls and foundation footings, causing cracks to appear.
Check to make sure all gutters and downspout drains are in good working order, and that the soil around your foundation is properly graded it should slope at least 6 inches for every 10 horizontal feet.
Most foundations are required to have a perimeter drain system, such as a French drain, that channels sub-surface water away from the foundation.
It’s possible for this drain to become blocked, causing water to accumulate in the soil and putting pressure on your foundation walls. If you suspect a blocked drain, you will need to hire a professional plumber in Metro Detroit to unclog it.
