"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."

"The entire staff from beginning to end have been wonderful! The crew that came to my house were the most polite group of guys, their parents would be proud! Everything was please and thank-you ....which along with craftsmanship, goes a long way when interacting with a company that you hire to do work in your home. Also, this company overall had the best warranty of those that we had come into our house to look at the job."

"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."

"I have not yet had the work done since I had just purchased the house back in June and am working on getting my head above water. However, I will be using them around February - March 2014. One of the owners called me today to follow up on the status of the job, if I am interested in it or not or if it has already been done by someone else. I was very surprised to hear back from them but am glad he reached out to me.
The man who came out to do the measurements was very knowledgable and friendly. He was punctual and professional. I was happy with the estimate and look forward to having this job done on my house and potentially other projects that I need to have done to my house.

"Desmond and Brian were awesome to work with! We purchased an old fixer upper and were really overwhelmed by the amount of work it needed. We wanted to do a lot of the work ourselves, but decided to hire someone to do the messy work for us. Desmond and Brian were more than willing to complete a partial job. We came across many contractors that would only renovate our kitchen from start to finish. After giving us an estimate, they were willing to negotiate some of the pricing to make us feel more comfortable with the cost. They were extremely fair with their price.
The communication was great throughout the whole experience. Desmond frequently called or texted with updates and questions. We were living about 40 minutes away during the renovation and Desmond would send picture updates on a regular basis. On one occasion, the people refinishing our floors (not affiliated with Desmond) accidently left one of our doors open. Our neighbor called Desmond and he came over right away to lock-up for us...so nice!
The work was excellent quality and they were able to complete it within the timeline we needed. We always felt comfortable having them in the house when we weren't there. Both Brian and Desmond are overall great people, did fantastic work, and were fair with work/pricing. We would definitely hire them again!

House Leveling questions, answered by experts

On average, a mudjacking repair lasts between five and 10 years, though it can sometimes last for well beyond a decade under ideal conditions. Its longevity depends heavily on several factors, including the condition of the underlying soil, environmental conditions like freeze/thaw cycles and erosion, and whether the root cause of the sinking, such as drainage issues, is resolved. Because it doesn't always fix the underlying problem of loose soil, mudjacking is often considered a temporary solution. Proper maintenance and evaluation can help extend its lifespan.

Polyjacking can be a permanent solution to sunken concrete if you also address the underlying issue—like poor drainage—at the same time. The polyurethane material itself can last as long as or even outlast the concrete you’re lifting it with. Your sunken concrete issue will likely return if you don’t couple polyjacking with proper drainage to prevent future soil movement and sinking.

There is no real alternative to underpinning, although mudjacking and polyjacking are other repair methods that can add support from underneath your foundation. Rather than placing supportive piers under your structure, these involve pumping a material under your slab to lift a sunken section back into its original position. Polyjacking, in particular, is sometimes a suitable solution for stabilization issues under slab foundations, but underpinning is often accepted as the best and most permanent solution.

Concrete leveling can last anywhere from five to 10 years or more, and in some cases, it can be a permanent solution. The longevity depends on the method used and whether the underlying cause of the sinking is addressed. For example, mudjacking typically lasts five to 10 years, while polyjacking can last for 20 years or more. It's best to consult a professional for an accurate timeline based on your specific situation and any factors that could cause the issue to recur.

Pros often use mudjacking or polyurethane foam injection to level a sunken concrete patio. Both methods lift the slab by filling voids beneath it. After properly compacting the soil beneath it to prevent future settling, the concrete may need to be removed and re-poured for severe sinking.
