"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!"
