"Just finished a visit with Foreman Doug and his crew, Devin, Sean, and Mason. Waterproofing the basement and super sound and solid work! Doug was professional and very good at keeping me in the loop with the project over the 3 day visit, and created a solid system that we are confident will keep water out of the basement forever. Above and beyond as well with problem solving when having to find solutions to fit our basement layout, all with a solid financing option/great price and 5 year warranty/ yearly inspection plan. If you are stuck with water in your basement, get Groundworks working for you ASAP!"

"I recently had my shingle roof replaced and I?m very happy with the results. The team was professional, punctual, and completed the job efficiently. The quality of the work is excellent, and the new roof looks great. They kept the work area clean and communicated well throughout the process. I would definitely recommend them to anyone needing a roof replacement."

"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."

"Mike did a great job fixing my chimney and replacing some of the bricks. He also waterproofed the whole thing. While he was up there he noticed a crack in the inside liner. He fixed that also. He showed me all the work before and after using a drone. Did a great job and didn’t have to wait long to get it done. He also fixed all the caps on my stone wall that had come loose. Everything looks great. May have a leak in the roof and if so will certainly hire him again."

"Price seemed a bit high for such a small job, but they could do it the same day. They did come down on the price when I agreed to get it done today. However since then Iâ ve noticed that the mortar in the patched area is nearly flush with the brick face, whereas the other mortar (the whole rest of the wall) is set quite deep in. The patched area really stands out as a patch. They didnâ t match the mortar depth to the rest of the wall. Iâ ve repainted the entire hearth to see if that helps, but itâ s still quite noticeable. Not impressed. Lesson learned."

Concrete Mudjacking questions, answered by experts

The method involves lifting settled concrete using pressurized cement slurry via drilled holes. This solves uneven surfaces and prevents further settling.

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.

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

Yes, expanding foam (also known as polyurethane foam) can lift concrete. This approach, called polyjacking, involves injecting the foam rather than concrete slurry to fill voids and raise the concrete slab back into place. It’s often faster and requires smaller drill holes than traditional mudjacking, though it may come at a higher cost. Some contractors also prefer polyjacking over mudjacking for more damaged and delicate slabs.

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