W. Santos Construction Services is a family-owned site-work contractor based in New Boston, New Hampshire that says it has been in business since 2008, working under owner Walter Santos on excavation, septic systems, foundation work, hardscape, concrete and masonry projects. The reviews read like a running list of finished jobs: a 40x60 metal barn built start to finish, from land clearing through the concrete slab, in an August 2026 Angi review; a new foundation drainage system and concrete walkway installed in about a week using materials the homeowner called good quality, in an August 2025 Google review; a 10'x12' hot tub slab that came out "perfect," with Walter walking the customer through the process before starting and the crew cleaning up after themselves, in a 2023 Angi review; and custom granite front steps with stone facing and railings for a customer who says he struggled to find anyone else willing to take on that combination, also in a 2023 Angi review. A different 2025 Google review describes the company fixing years of foundation settling and erosion caused by poor original lot grading on a 38-year-old house. Several reviewers name Walter Santos directly and describe him as showing up on time, explaining the process up front, and following through — enough that one customer says they've hired him more than once. On Angi and HomeAdvisor the company holds a perfect 5.0 rating from five reviews each; its Google rating sits lower, at 4.2 from five ratings, pulled down by one negative account. That negative review, from April 2025, is a different kind of complaint — the customer describes vehicles being parked in front of a driveway in a way that blocked access for hired workers to do their job, reading more like a dispute over site conduct than the quality of finished work. Both major directories list the company with 18 years of experience, Spanish-language support, emergency service, and free estimates, alongside its own site's claim of family ownership since 2008. Anyone hiring for excavation, septic or foundation drainage work should ask how the company handles site logistics on tight or shared driveways, given the one account of that kind of friction.
He did everything start to finish from clearing the land, pouring concrete slab, to building my 40x60 metal barn. Would highly recommend great price and very professional service Thank you!!!!
Walter and crew did great work installing a new foundation drainage system & concrete walkway. Got a great deal on pricing, project was completed in a timely manner (about a week), and the materials used are good quality. We purchased our own granite to be used for front steps, and they picked those up & installed them. Walter thought of things along the way that I wouldn't have thought of, like making sure there are drainpipes for future gutters, and they even installed a small pipe for our wired dog-fence under the granite steps. They also graded the ground when they were done. Great communicators and answered any questions we had along the way. Will definitely keep them in mind for future projects.... highly recommend.
I can’t say enough good things about W. Santos Construction Services! My house, built 38 years ago, had issues from poor lot grading and inadequate foundation drainage, causing erosion and foundation settling. I’d been researching solutions when I noticed my neighbors down the street getting a new drainage system installed. Their work looked high-quality—not the usual flimsy 4” perforated pipe but a sturdy 10” rugged perforated pipe. So, one day, I walked over and met Walter as he was wrapping up. He was super friendly, checked out my property, and explained exactly how to fix my drainage issues. We agreed on a great price and his team got to work. They removed my front stairs, then dug a trench. They power-washed and waterproofed the foundation walls, fixed cracks, and installed a perforated pipe wrapped in fiberglass, surrounded by rocks. For the gutters, they installed heavy-duty downspout drainpipes. They also regraded the yard to stop water pooling, added loam, and seeded. Plus, they installed granite stairs and a concrete walkway, blending perfectly with my driveway. Walter and his crew were professional, great at communicating, and everything they did was built for longevity. Walter mentioned his team handles everything—including interior construction, property maintenance, you name it—so we’re already planning to use them for a backyard porch, septic system, and new gutters. Overall, I’m thrilled with the results and highly recommend W. Santos Construction Services.

Throughout the project, they offered creative solutions to unexpected challenges, turning potential setbacks into seamless successes. Their problem-solving ability showed a depth of expertise and a genuine dedication to quality. Not only was the pricing fair, but their commitment to seeing the job through to completion was truly impressive. They remained on-site until every last detail was handled with care. We couldn’t be more pleased with the results, and we wholeheartedly recommend W. Santos Construction Services to anyone seeking top-tier craftsmanship, reliability, and innovative thinking.
The most petty construction company there is!!! Do not use these guys you’ll thank me later guaranteed. Parking vehicles in front of driveways just so guys that were hired to do a job can’t get in to do there job is just mind blowing. Sir you need to grow up and do the right thing instead of being petty. Hope this saves people a lot of headaches down the road. Have a blessed one!!!
