"life throws u curveballs and when our floor started sagging, we knew we needed help. we contacted the company and within days we had an estimate. nathaneal brewer, the field inspector, came out and made sure we understood what all needed doing, and how to fix it. he took pictures of the damaged areas, and made it easy to understand, and how to finance it all. the work date was set, and the crew, that came in, foreman, jozef and his helpers miike and garrett were very polite and easy to work with, they let us know what was happening and why, got along with our animals and worked hard to help us in an efficient and fast way to get it done. the work was done in a way that did not interrupt our daily life and faster than expected. a few glitches were address immediately and we would recommend that crew and foundation recovery to anyone needing it. thanks you guys"

"They were on time and did the job pretty quickly. After an hour that they finished the work, it rained. Until now, it's still raining so I can't say much about the quality yet. Their work was under warranty so I'll just call them if needed."

Foundation Repair FAQs, answered by experts

Yes, all basement floors crack in response to the natural settlement of the soil around them and from concrete shrinkage as it cures, and you’ll see hairline cracks as a result. However, you should keep an eye on your basement floor to see if cracks continue to lengthen or widen or show signs of water intrusion. In any of these cases, the problem is likely not settling or shrinkage, and a professional repair is necessary.

The best foundation repair method will depend on the issue you’re having, but usually, foundation instability is best fixed using supportive piers, like steel piers or helical piers. A professional foundation repair contractor or structural engineer should always decide what the best course of action is, and even then, it’s imperative that you also take measures to treat the underlying issue as well, like soil erosion or oversaturation from runoff.

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.

Not all cracks in the basement floor signal foundation problems. As the house settles, you’ll notice very thin hairline cracks, which you don’t need to worry about. Cracks that are 1/8 inch or wider should require sealing, while ones that are 1/2 inch or wider require leveling. However, if you have cracks in your basement floor with heaving, you should call a pro to assess the situation. Heaving can lead to uneven flooring, structural issues, and foundation problems.

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.
