With fully trained technicians, industry-leading products, and nationally backed warranties, Groundworks is here to restore your foundation or basement.

"We started having water leaks on a basement wall. Started slow but increased. We made the mistake of calling the big name TC H......, waited weeks to schedule first appointment. Finally showed up and proposed major excavation of basement wall, then applying new membrane. Unfortunately in our house, every external connection arrives via that wall. Talking electric, cable, septic, well water, and sprinkler. They wanted to use excavator to dig but wouldn't take responsibility for any potential damage. Price tag was very high. I was very nervous about this of course. I saw one source of water was around well pipe and other was wall itself. Contacted Marquis Well in Sanford who showed up immediately. Proposed hand digging at a lower price. They scheduled quickly, hand dug all the dirt, found Crack in water pipe casing and sealed up. But wall still had issue. Searched further and found Groundworks, lots of positive reviews. Called and they arrived quickly to assess. Beth is a true professional who knows her business extremely well. We signed proposal to inject sealant into cracks from inside of wall. Josh arrived to perform the work. He was effecient, very experienced who knew exactly what to do. During his inspection, he recommended bypassing one of the smaller Crack where water was never seen, thereby reducing our costs....unheard of! He completed the work quickly, zero mess or damage to our house. I cannot recommend both of these companies any higher. Both were outstanding in every aspect. Don't fall for the big ads from the others!"

"I have had Reuter Foundation repair come out twice to my house to fix some cracks in my block foundation and footing, and they were very respectful and reasonable with the entire process. I couldn’t have asked for a better local company to come out and do the work correctly as well as in a timely manner. I will definitely call them back for any other needs that may arise in the future as they made me feel confident and safe with the repairs they have made already."

SSG, or South Shore Gunite Pools, is New England's largest pool builder. We offer building, renovation and maintenance services to residential and commercial clients throughout New England. Headquartered in North Billerica MA, we have been setting the standard for gunite construction and quality swimming pools since 1975. We are shockingly unique in the way that we build, eliminating the uncertainty of relying upon subcontractors and operating with fully in-house employees. This strategy allows us to take full responsibility for our client's projects.

"Complete SCUMBAGS...Worked for months on design and install on new construction home...nothing ever goes according to plan. Once I had line of sight on project completion, I went back to schedule the job and these aholes Ray Varela and Bob Guarino jacked up my price by 5K (within 90 days). This was after several attempts to bait and switch on several quotes...adding here, removing there...trying to inflate the price decrease the scope. I have several quotes documented and will provide evidence to anyone who asks to prove my point...of course these scumbags will dispute my story...but I own the facts. Too many contractor options avail...STAY AWAY FROM SSG!!"
