"Tyrell did an excellent job correcting the mistakeS of the people who installed my basement waterproofing equipment. There was a terrible rotten egg smell and that's gone now. Tyrell cleaned up after himself, if any water spilled he made sure to vacuum it up and to dispose of everything in the proper place."

Foundation Repair questions, answered by experts

No, hairline cracks in concrete are generally not a problem as they do not impact the strength and longevity of the concrete. Generally, cracks less than 0.3 millimeter wide don’t impact the structure. Hairline cracks can grow over time and weaken the structure, such as in a home foundation. Some hairline cracks can also cause leaks in a foundation. It’s important to watch the cracks to see if they grow. Contact a concrete contractor if you notice cracks exceeding 0.3 millimeter wide.

There are many actions that specialists can take to repair a bad foundation. However, just like a car, a specialist will determine whether the cost of repairs is worth it in the long run. In many cases, repairs to the surrounding property—such as regrading your lawn or addressing lawn drainage issues—will also be necessary.

Around 25% of homes have foundation problems - it’s a very common issue. Foundation problems can range from very minor to severe and urgent. Call a foundation inspector to determine the severity of any potential issues you identify with your foundation.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

Homeowner’s insurance doesn’t cover foundation cracks unless they’re a result of a natural disaster like an earthquake, vandalism, or a vehicle accident that causes sudden damage. Taking care of your foundation to prevent problems with expansive soil and drainage is considered ongoing maintenance, and your insurance company expects the homeowner to carry out that preventative maintenance.
