"I bought a house in 2021 that had significant water damage leaking through the walls onto the concrete floor in the basement. After researching multiple companies around the area, I reached out to Basement Gurus. Ashley, Boni, Josh, and owner of the company Dan Kelly, all went above and beyond to make sure that there would be no more water damage. They installed a French drain, vapor barriers, and more. The owner Dan Kelly personally came out to make sure that the work got done correctly. This company is the best around, you won't be disappointed."

"I had a small but complicated, hard to access, and structurally essential repair job on a 60-year-old concrete deck attached to my 280-year-old Pennsylvania limestone farmhouse. I contacted several masons listed for my area on Home Advisor, and included Mr. Grady as a long shot -- I read about his expertise with historical structures and wished I had access to such an expert craftsman, but I didn't think he'd be interested in my teeny job and assumed I wouldn't be able to afford him anyway. He was the first one to return my call and to look at the job, and I thought his price was fair. I believe now it was way more than fair, considering the time he spent. He did extensive research, going over a structural engineer's report I had done previously on the deck and even examining the original architectural drawings and materials invoices from 1959. He showed up at least three times to complete the repair in stages, and has been back a half a dozen times since then to check the job -- and my location is not exactly in his neighborhood. He accepted only enough payment in advance to pay for lodging for himself and his assistant when they stayed nearby one night in order to be there early the next morning. He gave and continues to give free advice about preserving my stone house and patio. If you prod him a little, he might even share some of his personal philosophy, earned over a lifetime of work that is clearly more of an art form than a job to him. Overall, I'd say you can hire one of many competent contractors and get an adequate job, or you can hire Mr. Grady and get superior work by someone who cares about your property as much as you do."

House Leveling questions, answered by experts

Most projects take 1-3 hours, with immediate usability after completion.

Mudjacking is your best bet for leveling concrete on a tighter budget. It’s less expensive than foam or grout mixture. For smaller, surface-level issues, you could also use a self-leveling compound, which creates an even surface over existing concrete—it’s a budget-friendly option suitable for DIY enthusiasts.

Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs. 

Yes, you can mudjack cracked concrete, but the cracks will need to be repaired once the concrete has been leveled. If the concrete is severely cracked in multiple places, replacement may be a better option, but for less severe cracking, mudjacking is a good solution as long as cracks are correctly caulked and sealed.

Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The total drying time can vary depending on the size of the project. Because the slurry mixture contains cement, it needs to harden fully to prevent the concrete slab from shifting under added weight. You should avoid walking on the concrete or placing heavy items like furniture or vehicles on the surface until it has fully set. Your concrete contractor can provide a precise timeline. As a point of comparison, if you opt for polyjacking, the polyurethane foam can dry in minutes, but it's recommended to wait about an hour before use.
