Get matched with top foundation drainage installers and replacers in Harrisville, RI

"Wow! Unbelievable! If we ever have a water problem again, Pioneer will be the only waterproofing company that we call. We were getting some water in our basement which has a stack-stone foundation and radiant floor heating. We interviewed three companies and were particularly concerned about a solution that would stop the water without compromising the radiant tubes that were in the floor. Initially, Pioneer recommended a baseboard system that would run along the outside of the wall. Upon inspection, Mike Oliveira discussed a traditional drain to sump pump solution. We reiterated our concern about puncturing a tube in the floor and Mike assured us that he and his team would hand chisel potential problem areas to avoid the tubing. Moreover, this solution would save us roughly $2K and give us a lifetime guarantee vs. a 25 year guarantee on the baseboard system. The team showed up on time, cleared a 50' span of concrete by Noon, uncovered two sections of radiant tubing without puncturing the line, installed the moisture barrier, sump pump and new concrete by 4 p.m. They had to drill through a hefty header board to connect the pump line to an existing drainage line that carries water away from home and that was completed by 5:30 p.m. Mike came back in a week and we tested the fix using free-flow from our sprinkler system -- it worked perfectly. Subsequently we've had some consistent spring rain and absolutely no water in the basement. The team (including sales, service, billing, installation) was professional, courteous and available when we had questions. They saved us money, fixed our problem and provided a lifetime guarantee. We're both ecstatic and amazed!"

"About 2 months ago we had the techs from Diffley Drain Service out. At that time they ran a snake through the drain and pulled out a small root 75 feet down the line which at the time seemed to clear the backup which was manifesting itself in our basement utility sink. Thirty-three days later the problem manifested itself again and to their credit even though it was three days over the warranty period they came back out without any fuss. They snaked the drain again this time going out 105 feet without clearing anything. Now here is where things get a bit dodgy, rather than add a 2nd reel of cable onto the snake (or really even mentioning it) to enable them to snake further the tech tells my wife that they will need to install an external access point in the yard so they can snake further down the line and that will cost $3000. We say we'll think about it and explore other options. Once we watched some videos and educated ourselves about the matter we ended up hiring a different drain service. The new company we hired used 2 spools of snake to be able to go further down the line and cleared a bunch of roots 140 feet down the line. BUYER BEWARE with Diffley Drain Service they seem to only give you part of the story in order to seem credible. I will say that Diffley comes quickly and promptly which when you have sewer backup issues is a positive and they are initially reasonably priced but educate yourself about your problem or you will get taken advantage of."

"I couldn’t have been more pleased with the work performed or the professionalism and helpfulness of everyone I dealt with from sales to installation crew"

"I hired Stonecare Paving and Masonry to do some repairs on the concrete foundation on my home. They did a great job I was very happy with the work. Very professional company they kept us updated throughout the whole process. Everything was done in a professional manner. Definitely deserve five stars."

"The gals I worked with were really nice. They told me everything to expect and everything went exactly like they said it would. I paid exactly what they quoted me. I had no surprises - accept that it was exactly as promised! I never did expect to be as easy and smooth as it was."

"Ray and his team were incredibly professional, kind and courteous throughout all of the home projects. Their work on my basement foundation, installation of French drains and the rebuilding of an exterior wall were all phenomenal and at a very fair price. I highly recommend their services 10/10"

"Norbert and Adam are wonderful to work with. At a time when it’s difficult to find contractors who do what they say they’ll do, Norbert stands out… he and his crew are a joy rather than the typical headache! And their work—it’s just beautiful. Referred to us by a trusted friend (who also has a review here), we saw the quality of his work and hired them for a shed foundation with paver trim. We were so happy we hired him again to redesign our house’s front entry stairs, and stamp our front walkway, driveway lamp posts, and house foundation. It came out better than we could have hoped and enhanced the curb appeal of our house tremendously. Next, we wanted to raise a stone wall to help hide a home generator we had installed. This is where Norbert really excelled. He knew that we needed to reinforce the wall to support the generator… and he was right! They built a new one out of concrete, with french drains, to both support and hide it. As soon as we finished that, we planned our next project… a new stamped concrete driveway to replace our old asphalt one. They just finished it last week and it’s a WOW! We’re already talking about what our next project will be, so my advice—hurry up and hire him before my husband and I do again!! ;)"
