Noticing a Basement Wall Crack? We can help!

You might have noticed a crack in the wall of your basement. The crack might be horizontal, vertical, or stairstep, hairline, or wide and V-shaped. No matter the shape, wall cracks in the basement and/or foundation wall cracks can be either a sign of structural foundation problems or the result of normal shrinkage or settling.

Horizontal cracks may be accompanied by bowing walls.

Only an expert can determine whether the wall crack is compromising the structural integrity of your home, and whatever the case, provide the best solutions to fix it. The ability to see the crack and measure the width will allow a trained professional to understand the causes and potential risks.

Monitoring Basement Wall Cracks

Sometimes our inspectors will recommend that a crack monitor be installed to monitor any seasonal changes and wall movements. When we install crack monitors, we will ask you to take a picture of the monitor each month and email these to us for review. If we determine that it is a normal shrinkage crack, we will happily refer you to where you can purchase a “do it yourself” crack repair kit if you prefer.
