"We hired them to build a retaining wall to level out our sloped backyard and install a new patio. They recommended natural bluestone bordered by classic bricks, and wow?what a difference! The stonework is flawless, perfectly level, and handles heavy rain with zero drainage issues. It looks like a high-end resort back here now. Worth every penny."

"I have worked with Uprise twice now and both times they did great work. The first house they found and repaired a leak, and in the second house I had them install a new roof. I would not hesitate to call them again for future needs."

"For the price you pay, the quality of work is excellent. Very accommodating in terms of timing on when the installation could be done. When reviewing billing and pricing, all iâ s weâ re dotted and all Tâ s were crossed. Time will tell how well the quality of job holds up, but I already noticed my house being IMMENSELY quieter prior to the new roof installation, which should speak to some level on the quality of work and materials used. All work was done in a single day, which was also fantastic, and then all work was reviewed by the owner himself, which was a very nice touch."

"Full waterproofing of the basement in our 95 year old house, including demolition of walls and shelves/cabinets/sinks and plumbing. Additional service of adding a footing to the basement walls. All the work took three days. Excellent work and looks great, though a bit costly."

"Luis and his crew arrived promptly at the prearranged time. He introduced himself and we went over what they were there to do. They proceeded to bring in their equipment and went right to work. When the Sump pump and dehumidifier installation was completed they went over how it worked, advised how to register the respective warranties and started the new equipment. They thoroughly cleaned up the basement where they were working. Luis also went over the outside discharge line for the sump pump. I then exited the house while Luis sprayed for the mold conditions in the basement. I was very satisfied with the professionalism of Luis and his crew and will definitely recommend Quality 1st basements to anyone who are looking for this type of service."

"This company was a great to work with. Very professional and quick! They were able to complete my entire basement project: installing a french drain, sump pump, and rough casting on the walls in just one day. They brought in a large team to ensure the project was done correctly and efficiently. They also made sure to use drop cloths and plastic around the house to keep dust off of my furniture. This was very appreciated. The salesmen were great to work with and have the credentials/experience to back it up. Would definitely hire again!"

House Leveling questions, answered by experts

Polyjacking and mudjacking can both be effective solutions for sinking concrete, but they have key differences. Polyjacking, which uses expanding polyurethane foam, is often considered a better option because the foam is significantly lighter than the cementitious material used for mudjacking. This reduced weight puts less pressure on the underlying soil and lowers the risk of future sinking. Polyjacking is suitable for any sinking concrete slab, while mudjacking is typically only recommended for non-structural concrete, such as sidewalks, patios, pool decks, and driveways. The primary drawback of polyjacking is its cost, which can be up to four times higher than mudjacking—as much as $25 per square foot compared to a maximum of about $6 per square foot for mudjacking.

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 states and municipalities don’t require concrete mudjacking companies to carry a specific license, but they usually need to have a general contractor’s license, and they should be fully insured. The only exception is if the mudjacking company provides foundation repairs as well, or if it offers mudjacking for home foundations. In that case, they will typically need a foundation repair contractor’s license. You can check state requirements and then use Angi’s license lookup tool to confirm that a company is properly licensed to provide mudjacking services in your area.

The average cost for mudjacking is around $1,200, though prices can range from $300 to $3,400. On a per-square-foot basis, you can expect to pay between $3 and $8, with an average of about $5 per square foot. The final cost depends on several factors, including the square footage of the concrete, the type of slab, its accessibility, whether it is load-bearing, and the type of material used to lift it. Generally, lifting a driveway, small patio, or sidewalk is less expensive than lifting a slab foundation or garage floor.

The polyurethane used for polyjacking will expand and cure in 15 to 30 minutes. After that point, your slab will be safe to walk on and even drive on in the case of a sidewalk or concrete driveway. Double-check with your concrete lifting specialist to confirm a curing timeline, as products can differ.
