"Arthur gave us a fair and competitive estimate and was able to start work quickly thereafter. He and his team did an excellent job gutting and totally remodeling two bathrooms and a closet as well as redoing some of the wood flooring, moving vents, and moving hallways. Arthur himself was at the home everyday and did the important work himself. He also went the extra mile in helping us with small projects around the major project as they came up. He was extremely responsive in provided us with timely updates. When complications occurred (due to the house having not been renovated in 40 years) he was clear and helpful in keeping the project on schedule. He was extremely honest and I trusted him to be alone in my house for weeks on end with his team. I would/plan to work with Arthur again in the future for my home renovation projects."

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"Anthony and his crew were friendly and professional throughout the whole project. Anthony gave us a clearly broken down estimate prior to starting the work and we were very confident in his work from start to finish. He and his crew did an excellent job and we would absolutely use him again for future projects. His prices were reasonable and comparable to other quotes we received-he provided us with a clear payment schedule over the course of the project, communicated with us every step of the way and went above and beyond to give us tips and additional info that was helpful to us as new-ish homeowners. Would absolutely recommend."

"We've never had luck with major home modifications—this was smooth sailing the entire way. Our project was a teardown and complete re-side, and Cocos did a fantastic job. We have a tricky home with a lot of angles that make no sense—Cocos did a brilliant job strategizing how everything should be executed, and the 50-year-old home looks brand new. Danielle, Keith and Matt not only executed at the highest level, they stayed in communication literally every day to make sure there were no surprises and that we were happy with the progress. If you're looking for a home siding partner, don't hesitate to hire Cocos. They were top notch and we are very happy/"

"Torres Contracting did an outstanding job repairing my old front and side stoops that had significant water damage. On time and at an extremely fair price. His masons then built two matching brick/bull nose flower beds in front of house. Beautifully done and I received many compliments from the neighbors!"

"I hired zavza seal to finish my basement and I am pleased with their work. I have dealt with many contractors over the years, unfortunately these experiences are often full of frustration and stress. Not the case with Zavza seal, they are completely professional and put the customer first. Anderson and his crew were courteous, hard working, and efficient. They came when they said they would and cleaned up everyday. Jake was the project manager for this job, he is an honorable man and very easy to work with. He was onsite every day from the estimate to the finishing touches. There was constant communication, I knew what the plan was each day and he was always very responsive to any questions. I've had other pm's disappear to other jobs, or push me toward doing things in a way that was easiest for them. Jake was very collaborative, and his focus was completing the project to our satisfaction. Midway through the work I asked for a couple of changes that were not in the original estimate (storage room and laundry shelving). Zavza added them in at no extra cost. My house is old and presented challenges with regard to the floor and ceiling joists. The crew took the time to do things the right way without shortcuts. Jake came out and worked a full Saturday and Sunday to ensure that the ceiling was right and the project was finished on time. Not many companies take pride in their work like this these days. It was refreshing to see. My basement is now the nicest room in the house. Zavza Seal went above and beyond and I wholeheartedly recommend them."

House Leveling questions, answered by experts

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.

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.

Many contractors offer warranties for their work. Confirm terms before starting the project.

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 is usually reserved for light-duty slabs, like patios, driveways, and sidewalks. However, it can be an effective way to lift garage slabs and concrete around the perimeter of the home, which could harm your foundation if it’s not done properly. The risk of damage is why having a professional mudjacking company carry out the work is important. This type of slab or foundation repair is relatively inexpensive, especially if you consider that a DIY job requires that you pay to rent the necessary equipment.
