Verified record
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Atlantic Coatings. 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.

Atlantic Coatings is a Weymouth outfit built around basement work — sump pumps, foundation crack repairs, crawl space encapsulation. Angi describes it as run by owners Jeff and Dave, and Jeff is the one customers say they dealt with directly. Its three reviews are all 5 stars, and they describe the same kind of job. One homeowner called with a wet basement and got a new sump pump plus foundation-crack repairs that stopped the leaking for good, with the work explained clearly along the way. Another customer credited Jeff with walking them through the whole job and called the crew punctual. The company holds an active Massachusetts home improvement contractor license (HIC #216595). Angi separately lists a Massachusetts trade license, CS-120210, for the business. Its Better Business Bureau file carries an A grade — it hasn't sought BBB accreditation — and shows the company opened in January 2025. With only three reviews and a year in business, there isn't much history to lean on yet, but what's there points to responsive, clearly explained basement repair work — a strong call for a wet basement or a cracked foundation. Given how new the company is, ask for a couple of references before booking a larger job.
Jeff is extremely knowledgeable and does a great job explaing the entire process from start to finish. Jeff and crew were punctual and very professional. I would definitely recommend Atlantic Coatings for your roofing needs and will be using them in the future.
The best!
I had a wet basement and called Atlantic Coatings for help. They installed a new sump pump and repaired several foundation cracks, and the difference was immediate. Everything was explained clearly, the work was done professionally, and the basement has stayed dry since. I'd definitely recommend them to anyone dealing with water issues in their basement.
