"This is a review of the *experience* we had with Quality. We had the basement waterproofed, so we won't really know how good the job is until a big rainstorm! So this is just the experience we had before and during the job. We reached out to Quality based on the Angie's List reviews, and were convinced by the visit from Greg. He was so knowledgeable about the water problems, and pointed out the years of experience the company has. Also, we weren't looking for a bargain, we were looking for a dry basement, and Greg was very straightforward about all the costs. Now we haven't had a rainstorm yet, so we still don't know the most important thing about the job! But Victor and his crew were fantastic. They knew what they were supposed to do when they got here, and did the whole job-- as quietly as possible-- in less than 4 hours. They were pleasant to have in the house. They left the place clean. So big thanks to all at Quality. P S: Will update when there's a big rainstorm."

"They did a great job!! The house painting job took about one month to complete because of the scraping and other prep work that was needed. I have a English Tutor style home that hadn't been painted for 12 years and in some places the wood planks needed to be replaced. Once the prep work was completed the workers applied one coat of primer and two coats of paint. For each job, the cost estimate included the cost of materials. There prices are extremely reasonable given the high cost of all the materials they used to complete these jobs. The house exterior looks great now. They painted the house using Benjamin Moore Regal Select paint. This is the best exterior paint made today. In the fall I had Gaudioso Contracting come back to complete some additional repairs involving securing my yard wooden fence that had fallen down from high winds and some driveway cement work. The guys fixed the fence in one full day and and completed the concrete work also in a single day, In each case there was a crew of 3 men who because of COVID wore masks the entire time and totally cleaned up each work site after the repairs were completed. I was extremely satisfied with their knowledge and skills. I would recommend Gaudioso Contracting for all small and large home construction improvement projects. Their foreman gives accurate cost estimates and the workers are skilled experienced craftsmen who take the time to do the job right!!."

"Mickey performed excellent work at my house. I hired him to fix my retaining wall and steps at first then secondly my basement was mess with water coming in. Mickey helped with demo as I decided to remodel the basement as well, then he waterproofed my entire basement. Finally, he leveled out my basement floor. The work was absolutely immaculate and on top of that he was extremely helpful throughout the process and not once did I ever have to stress or worry. Great service and a great guy. I highly recommend Mickey if you need ANY type of masonry or stone work."

House Leveling questions, answered by experts

Charges correlate with surface size, settlement depth, and access, often yielding significant savings over concrete replacement.

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.

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 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.

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.
