Cracks spreading through a foundation can point to a variety of issues, all of which can be a substantial threat to the stability of your home. In time, water penetration and erosion can worsen a cracked foundation and cost thousands of dollars to repair. Below are answers to some common questions you might have if your home inspection reveals cracks in the foundation.

A Brief Guide to Foundation Cracks

What causes foundation cracking?

Many cracks are caused by soil compacting or settling underneath the house. This places more stress on areas of the foundation that are no longer level, often resulting in vertical cracks.

In other cases, cracks can be caused by plumbing leaks or even tree roots working their way into the concrete. Soil saturated with excess water can also exert too much force on the foundation walls, causing cracks that extend horizontally across the surface.

Are all concrete cracks serious?

Some cracks stop developing after a house settles, but many indicate serious issues that can affect every part of the house. If cracks spread up the walls of the house, appear at the corners of doors and windows, or seem to be growing, the problem is likely severe. A home inspection professional can help determine whether the cracks in your home will lead to serious issues including pipe damage, leaks and flooding, and uneven flooring and door jambs.

Can foundation cracks be repaired?

If cracks are most prominent on the inner foundation walls, a contractor can use polyurethane to waterproof the concrete and minimize future damage. Exterior wall cracks can also be sealed with hydraulic cement. However, you may need to install new drainage in the yard and level the home to fully resolve every foundation issue.

Can foundation cracks be prevented?

Cracking as a result of soil settling may be unavoidable. However, you may be able to prevent cracks related to poor drainage by keeping roof gutters clear and preventing water from pooling against the foundation. Periodically scheduling a professional to inspect for foundation-related damage can help you address problems before they affect the floors, walls, and the roof.
