"We needed a reliable contractor to fix problems with our foundation. Lux Foundation Solutions was recommended to us based on previous work by the West Virginian realtor we worked with for our house. First, Matt came out, performed an assessment and explained everything well. He was friendly and answered all my questions about the work being performed. That set the tone for a great experience! After the estimate was received I made an appointment. The day of the appointment Adamâ s team arrived exactly on time: I live somewhat remote and that his team was on time really speaks for the company and itâ s work culture and ethics! Adam and his team worked in the crawl space, which was difficult for me to get into. Adam kept me informed throughout the process and even took pictures after the job was done to show me the results. The quality of the work speaks for itself! Iâ m very happy to have hired Lux Foundation Solutions and they are my first company to call if another job needs to get done! I highly recommend the company for your crawl space work!"

"We are extremely happy with the work done by Thomas Custom Builders (TCB). Overall they did an amazing and outstanding job! They had a contractor on site, on time every day. Brian S. was professional, helpful, patient, hard working and skilled both in managing subcontractors and doing work himself. I trusted him with our home and would work with Brian/TCB again easily. I have already recommended their company to others. TCB renovated a few parts of our house, added electricity to a shed and added an entire master bedroom suite on an additional floor (adding approximately 550 sqft to our house). They finished earlier than expected. Our neighbors couldn't believe how fast the addition was completed and how well done. Any additional costs from the original budget estimate were due to our choice to add more work. I waited to write a review. I wanted to live in the addition for a little while to see how everything holds up. We have had only minor things arise and have been very pleased with the responsiveness of Brian and TCB to come back out and check on things. They came back to add a bracket to a new countertop that moved slightly, they shaved a door that was sticking as the weather changed, they fixed the damage done when carpets were installed by another company, they arranged for a rep from the hot water heater company to come out and fix a noise issue, all done at no additional cost to us. I have worked with contractors before but nothing on this level. It wasn't perfect, there were concerns that came up. I had to learn that this was major construction and with major construction comes mess. Brian and his team addressed our concerns and remedied any issue fairly. With so many negative stories I've heard from people who worked with other companies, I am so very thankful that we had such a good experience and ended up with such an amazing master suite and changes to our home. We love it and we receive many compliments. We chose to work with TCB because they came highly recommended by a neighbor who had similar work done and were very satisfied with their outcome."

"The project manager of the remodel, Jason, was always in contact with me about when workers would be at the house and to see how everything was going. He also stopped by the house to check on the work. Ismar, the head employee of the job, was very good. He put down tarps to cover the floors and put plastic about the furniture and cabinet in bathroom. He also put up plastic between the bathroom and the bedroom to minimize the dust. The workers were very professional. The tile work in the shower was great. They also had to hang some drywall to fix a closet and paint it. It looks like that was always how the closet was. The shower come out beautiful. I would highly recommend the company and would differently use them again."

"Exterior Waterproofing Experts tied in my downspouts to an existing underground system to move water away from my foundation. They installed four inch gutters and downspouts as well. Prior to installation of downspouts the crew discussed placement and color options with me and explained their planned approach for the underground piping. I was very impressed that installers would take the time and show the concern to engage with the home owner at the time of installation to verify that the placement and color were satisfactory. After the gutter installation a heavy rainstorm tested the system and resulted in a few minor leaks that the contractor promptly resolved. All ground work was leveled and shrubbery returned to the flower beds. Exterior Waterproofing Experts performs excellent work and engages with the home owner like no other contractor that I have experienced. I can highly recommend them for all drainage work based on my experience."

"The crawlspace in our recently purchased house was a mess—full of water, mold, and deteriorated insulation. NV gave us a competitive price, on par with the other bids we got, and their bid seemed more comprehensive than some of the others. Jaime did an excellent job explaining everything to me and talking me through any questions we had. Once the work began, Manny and the rest of the guys did a great job—they were on site promptly each day and were clearly working hard over the three days of the project. Manny was very communicative and easy to work with and even went out of his way to help us with some extra items in the yard. The crawlspace looks awesome now—clean and dry! Thanks again to the NV Waterproofing team for all their hard work and helping us clean up a rough part of the house!"

"Today I met with Howard Glancy from JES Foundation Repair regarding the outside water seepage problem in my house. The water is coming in the bottom-level of my 3-story townhouse (end unit). My townhouse is the last unit located on the bottom of a hill. I also have standing water in my back yard every time it rains. Howard has very impressive credentials and is an expert in his field. After an inspection of the problem area, Howard gave me a very detailed explanation of what needed to be done to fix the problem. The water is coming in up from the ground underneath my house. The previous day I had a meeting with a representative from a different company who said it would be a simple fix with just a french drain on the side of my house. Howard explained why a french drain would not fix the underlying problem. I have decided to go with JES Foundation Repair and feel confident that I made the right choice."

"From initial contact with their sales department we've had a great experience, Corey did an excellent job of taking pictures and showing the problems in our attic. Their level of communication from emails to phone calls was precisely correct by contacting me when needed and not too much with pictures detailing each solution and its associated cost. On the first work day their crew called ahead of time, arrived promptly and came prepared with masks, plastic sheeting, full body outfits and cloth covering for the stairs. In just over 6 hours they had cleaned up the entire attic removing bad sub-floor and other insulation, laid out the foundation for building a large deck space and placed part of the first layer of materials down. They also sealed the attic door along with some of the air vents and ceiling fans. They completed insulating my front porch overhang and cleaned up all of their mess very well. Painters tape was used on corners where they weâ re most likely to bump into it for protection and plastic sheeting was setup precisely where needed to keep dust off of our hallway things next to the attic entrance. Overall it was a great first day and they even spotted an issue from a previous vendor who failed to properly connect some of their duct work together (which was the original cause of my daughterâ s room temperature being so hard to control the temperature and not easy to spot). The only complaint I have is that while I fully expected the need to finish our attic sub-floor, remaining layers of TruSoftTM Cellulose on the main floor and encapsulate the duct lines with Polyurethane Spray Foam all before finishing with blown-in insulation, they left a key piece incomplete. When leaving they left the duct work leading from our main trunk line to my daughterâ s room off. This left a hole in the main trunk line reducing heat in all upstairs rooms but most important is that nothing was connected to my daughterâ s room. So around 6:00am she woke up coughing as we noticed the upstairs was around 56 degrees. Overall a simple heads up would have solved everything as we have space heaters, however I did not look into the attic when they left so thatâ s my fault for not knowing a key piece of the duct line was missing. Based on the overall work complete I would still very much recommend them as Robert (onsite team lead) was very good at communicating and the crew weâ re all quite friendly. Their work will last for the lifetime of my house and has already added value to the sale price. In the end they made a really nice attic deck leaving me with plenty of useable storage space. While this is not the cheapest company, the quality and knowledge that I never need to worry about my attic again is certainly worth it."

House Leveling FAQs, answered by experts

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.

Mudjacking is suitable for sidewalks, driveways, patios, and nearly all exterior flat structures. However, it may not suit severely damaged or heavily cracked areas.

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.

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

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