"Highly recommend Sean! He showed up on time, was very professional and repaired 2 leaking walls in my poured concrete foundation. I had tried several times with various products and the water just kept finding its way in. So frustrating! Even had another company come that said I needed the floor cut and a drain installed. They wanted almost $6000! Sean fixed the issue in a few hours. Left the place spotless and the basement is now totally bone dry. Also guarantees his work and offered to return at no charge if the issue returned."

"From the beginning of the project to the end, Basement Gurus made the process feel painless. They gave me a clear understanding of what remedies were necessary to fix my foundation and ensured that all of my expectations would be met. The contracted workers were timely, considerate, clean, and personable. I would strongly recommend Basement Gurus for any waterproofing work and will be using them as often as necessary in the future."

"Great experience. The technician fixed the leak, even though he really did not have any openings the day I called. He just wanted to stop it raining into the house. Then they came back out and did all the repair work on time a few days later, as arranged. Fast, efficient, but also genuinely interested in helping you out. I cannot say enough about these guys."

"Sam and his team quickly identified my water issue, and fixed the problem within 2 days. Given the quality and speed of the work to repair a rather significant water issue, i contracted them for additional preventative maintenance on our 45 year old foundation, and 22 year old roof and gutters. Will most certainly engage them in the furture for any other related work."

Foundation Repair FAQs, answered by experts

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.

No, house settling is normal as your home’s foundation settles into the soil below and as the framing of your home shifts as it expands and contracts with changes in temperature and moisture. However, if you get to the point where your doors and windows aren’t opening easily, your floors are uneven, or you can visibly see that your roof line is wavy or uneven, you are more likely to have foundation issues.

Efflorescence can damage a concrete slab for two to three years. After that, it resolves on its own once the surrounding salts are gone.

Foundation repair can affect home value positively or negatively. If you address the underlying issue and hire a foundation repair contractor to complete the work—especially one that includes a warranty for the work—then your repair will likely increase your home’s value. If you fail to pull proper permits and cannot prove that a licensed expert completed the work, there’s a chance buyers will view your home in a negative light and end up offering less for your property.

Yes, slab foundations can sink just like any other foundation type. Floating slabs are the most prone to differential settlement and foundation sinking because they sit directly on the surface of the earth. Slab foundations that have footings—including slab-on-grade foundations and monolithic slab foundations—get additional support from soil further down and are less likely to sink over time, especially under larger, heavier structures.
