Pioneer Basement Waterproofing

Pioneer Basement Waterproofing has been on Westport's radar since well before online reviews existed — the company has held BBB accreditation since 1993, and its Massachusetts home improvement contractor registration is active. That tenure shows up as consistency: 870 reviews stretch back to 2016, and the last six months alone brought 188 reviews with not one negative among them. Google puts it at 4.9 stars across 1,059 ratings, Angi at 4.7 from 188. The name that comes up over and over is Alfredo — dozens of reviews describe him running maintenance and pump-replacement visits with the same care, and one homeowner recounts him cleaning out an old pump first, at no charge, just to check whether that would fix the problem before recommending a costly replacement (it didn't, but the reviewer appreciated the attempt). Other named technicians — Rick, Nate, Johnson, Rafael, Sebastian — draw similar praise for walking customers through what they're checking rather than just doing the work silently. Installation jobs get described in real detail: a 2022 review recounts a crew trenching a vapor barrier and collection channel through a Cape Cod basement's concrete floor in just over a day, leaving the space clean enough to finish; a 2024 review describes a full sump-and-backup-pump replacement plus improved exterior drainage that held up through a stretch of heavy storms. It isn't spotless. In a 2023 review, a customer described the estimate for a job being rewritten to a higher price after an expected service-call credit failed to materialize — the credit then subtracted from the inflated number rather than the original quote — and said coordinating equipment moves for the job was left entirely on them. And in a 2025 review, a longtime customer noted that water returned to their basement years after Pioneer's original work; the company came back twice to fix it, proposing a further paid job to resolve what by then looked like a different, newer problem. BuildZoom shows a single 1-star rating for the company, sharply out of step with everything else on the page — worth knowing about but hard to weigh against a 30-year, nearly-900-review track record built mostly on named, detailed praise. Before booking, it's worth asking how any service-call credit will actually apply to a written estimate.
