Get matched with top foundation drainage installers and replacers in Manchester, NH

"Paul Swann evaluated our foundation problem and referred us to an engineer who provided a detailed repair plan. Unfortunately, the nature and scope of the proposed repair plan was outside the parameters of what Northern Basement System's themselves could provide. We appreciated their honesty and have been looking for a contractor to take on the project."

"Everything completed as rescheduled after a weather delay. The crews arrived on time, did the project (2 foundation Cracks, and cleaned up"

"Took waaaay to long. 6 months, albeit, we started in late November but it was the nicest winter in history. Promise was late February for completion. I finally conceded in June that they had finally met all contractual obligations. There were several reasons it took so long from my point of view: not showing up when they say they are, poor workmanship requiring lots of rework (all caught by me, not the so called Project Manager), no dedicated project manager, unclear instructions/requirements flowed down to the contractors sent to do the work, company too focused on the next jobs instead of completing this one, etc..I could go on and on...Damaged my driveway and blamed the driveway even though I asked upfront if there would be any harm to it. "No we do this all the time" was the response. Damaged my neighbors lawn and I'm still fixing that. Overall, a bad experience. I'd rate them a "D" but they did eventually fix most of the quality problems. The rest I have, or will take care of. Cutting the ties with this contractor. Would not recommend."

"These guys did such a fantastic work with sealcoating our driveway. The level of attention to details these guys put in is unmatched! Highly recommended."

"Ken and Rowan are a pleasure to work with and we could not be happier with the work they did for us. They took a very large, pea stone patio area from sad to amazing by adding curbing along three sides (to separate the pea stone area from the lawn and driveway), refreshed the pea stone in between pavers on our long walkway, and we able to smartly cover up some ugly yard drainage while allowing it to still function properly. Our project was a bit unusual but they had the expertise (and enthusiasm!) to help us figure it out. They spent many hours beforehand problem solving and planning out the project with us. Ken communicated with us throughout all the materials purchases and both Ken and Rowan were very responsive to all our requests. On top of that, they got the project done within a tight timeframe as we had a deadline. We gained so much confidence in them that we have 3 more large projects (large retaining wall, walkways, and a drainage area along our driveway) that we plan to hire them for!"

"Eddie did a fantastic job. He was able to come earlier, which helped me out. He explained what he was doing and got to work. One drain was a particularly hard job, but he kept at it until it worked perfectly. There were no hidden charges or attempts to jack up the cost. When he finished, he cleaned up completely. I would definitely recommend him and use him again if we need to."
