"As first time home owner, it is tough finding service people who are reliable and trustworthy and who aren’t looking to just patch the problem. AJ did everything he could, short of coming to assess the problem in person (because of Covid), to address the issue I was having with water in the back of my house. He is very responsive and very knowledgeable! I walked him through the problem over facetime and afterwards he gave me a clear assessment of what exactly was happening (in a way I could understand) and instructions as to what to do to fix it. It ended up being a problem that had to be addressed by a roofer, but I wouldn’t know that without AJ. I definitely recommend AJ if you need a knowledgable and reliable home water expert! Thank you for your excellent service!"

"My house is located in a wet area and I always have water coming into my crawlspace, even if it hasn't rained in several weeks. The moisture issues are compounded by the presence of iron ocher, which would cause the trench drain and sump pit in my crawlspace to clog and overflow unless I crawled back into it and treated it with bleach/chlorine every week. Basement Systems suggested a plan to install a new drainage system and relocate my sump to an area that would be much easier to access and maintain. They upgraded the existing sump pump to a triple safe system with three pumps (including a battery backup!) so I have multiple redundancies in place to prevent flooding. They also wrapped my crawlspace with a heavy duty vapor barrier to keep all of that moisture from permeating up through my house. I couldn't have been happier with Javier and his crew, and my wife had no qualms about having them in our house while I was away at work. They called me several times to communicate their schedule, and took care to protect the flooring on the main level of my house. Javier was more than willing to work with me to route the sump discharge pipes in the area I wanted them. He and his crew worked very hard and put in extra hours to have the job completed on schedule in two days even though they ran into several unexpected issues. I couldn't be happier with the quality of work, the professionalism of the crew, and the integrity of company, and wouldn't hesitate to recommend Basement Systems to anyone."

"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."

"This is the second time I am using the company. They first did a great job on my rental property that is 150+ years old. For this review, Anthony, Carlos and his crew took care of my primary house that is roughly 80 years old. Carlos and crew showed up a bit late due to traffic, apologized profusely for the delay, which I was fine with since it was out of their control. The crew stayed late and finished the job in one day. The work was nicely done, the worksite was kept clean and the crew were very organized. I would highly recommend them."

"Make sure the person giving the estimate explains exactly what it looks like. They did not bring their own water to mix the cement. We had to remove the water tank so that they could work and ended up hauling water from the neighbors house."

"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 FAQs, answered by experts

A slurry of cement, sand, and water is injected beneath the concrete to lift and stabilize it.

It’s best not to perform mudjacking in the winter unless the ground temperature remains above freezing. Freezing temperatures can cause the slurry to harden too quickly, compromising its strength and longevity. Concrete is also more susceptible to cracking and splitting in cold temperatures, so there’s a higher risk of damaging the slab during the drilling and lifting process in winter.

Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The exact time can vary depending on the size of the project. Because the slurry mixture contains cement, it must fully harden to ensure that added weight from walking, furniture, or vehicles won't shift the concrete slab. A professional contractor can advise you on when the surface is safe to use. For comparison, if you use polyjacking instead, the polyurethane foam can dry in just a few minutes, but it's best to wait about an hour before use.

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

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.
