"Mike was able to fit me in the same day for an estimate which surprised me because I'm sure a lot of people are needing his services with all the rain lately but he was in the area that day and came by. Although the company is a nation wide chain, its a franchise and a small business. He is an honest Vermonter with Vermont values which I appreciate. He gave me options but didn't try to talk me into something I couldn't afford and is doing the work within two weeks which I was also happy about being a very busy time for this type of thing."

"We are in the second day of this project. Bryan had to hire another person to work with him as his regular employee is recuperating from an emergency situation so the work will take longer than expected. My husband says he's doing a good job ,as the work is in our vacation home in NH and I am in MA. Brian will try to have the wall finished by Thursday but will have to come back one day next week for the remaining seepage part of the job."

"Mike showed up on time and provided an estimate for the work he would perform. He and his mason arrived the next morning as agreed and his mason went to work disassembling and grinding all the mortar joints on my old chimney. We ran into an unanticipated issue that Mike quickly resolved and his mason completed the work in one full day. My wife thinks the new repair looks great. We are happy to have it fixed prior to the next heating season."

Concrete Leveling FAQs, answered by experts

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

Concrete leveling is absolutely worth it if you have sunken concrete slabs and want to restore them to level, especially if the slab is part of your home foundation. Concrete leveling is less than half the price of replacing concrete sidewalks, patios, walkways, and pool decks, and it’s about a quarter of the cost of replacing a foundation. If you also treat the underlying problem, it can be a worthwhile and permanent solution.

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.

Address drainage issues, avoid heavy loads, and seal cracks to prevent future settling.

Costs range from $500 to $1,500, depending on the size and condition of the area.
