Verified record
Bass Restoration & Waterproofing is a Hanover-based masonry, waterproofing, and concrete-restoration contractor that says it has more than 40 years of experience, though its site names no specific founding date. Its stated focus is commercial, industrial, and historical buildings across Greater Boston and Eastern and Central Massachusetts, rather than typical residential jobs. The written record here is essentially nothing to go on: just two reviews, both from 2025, and they contradict each other — one is a bare "Great company," the other a bare "Every single thing is bad," with no detail behind either one to explain what happened. Its Massachusetts home-improvement contractor registration is verified active by the state registry, a real point in its favor — but there's essentially no independent track record here to evaluate before hiring, especially for a residential job when the company's own stated focus is commercial and institutional work. This looks built for larger commercial or historical restoration work rather than a homeowner's basement — worth confirming they take on residential jobs at all, and asking for references directly given how thin the public record is.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Bass Restoration & Waterproofing, Inc.. Use it to sanity-check bids, then get the real number in writing.
Not sure which you need? Start with an inspection — many reputable companies assess free, and independent assessments run up to $500.
The wall run getting the drain — a full 30×40 ft basement is about 140 ft.
