Ram Jack New England is a foundation repair and waterproofing outfit working out of Wareham, handling the kind of structural work that shows up over time — cracked foundations, sinking slabs, and basements that won't stop leaking. It's Better Business Bureau accredited with an A+ rating (also doing business as Northeast Foundation Repair, LLC), and Angi lists it as a member of the Home Builders Association of Cape Cod. The strongest thread across years of reviews is fixing problems other companies couldn't. A homeowner who got quotes from three companies for basement water leaks says Ram Jack was the only one that actually solved it, at a reasonable price, in a late-2025 review. Reviewers describe cracked foundations repaired (Mike Parsons walked one customer through a multi-crack repair in a 2023 review), a sunken pool apron brought back level and sinking condo garage-floor entrances fixed in 2024 reviews, and a 2022 review recounts an extensive retaining-wall crack repair the crew finished beyond the original scope. Customers repeatedly mention thorough on-site walkthroughs before a quote — a 2024 review describes an estimator spending two hours on-site working through what the homeowner actually wanted. Not everything here is smooth, though. A 2023 review describes being told the company couldn't do a house-leveling job ahead of a deck replacement, then never hearing back — a pattern echoed in a much older, 2015 account of an estimate that went two months without a response. Another 2023 review, despite rating the job five stars, describes being quoted roughly four times what a competing company charged. A 2021 review cites slow scheduling it attributes partly to COVID-era delays, and a separate 2021 review describes dissatisfaction with how finished footings looked. A 2022 Angi review otherwise praising the crew notes some leaking was later observed. Recent activity is thin — just one review in the past six months, a five-star account calling the work first class — so most of what's here to go on is the multi-year history: 23 reviews from 2016 through 2026 across Google and Angi, mostly positive, with real but occasional complaints about pricing and follow-through. For a foundation crack, a sinking slab, or a leaking basement, the history leans toward getting the job done right; it's worth asking for a firm, itemized quote up front given the pricing complaints some reviewers describe.
“Had Ram Jack New England come out to do an estimate on foundation repair for our house. Nearly two months later, still no estimate and no response.”
First class service and workmanship! Highly recommended.
Out of 3 companies that I received quotes from to address water leaks from rain/windstorms in multiple areas in my basement, Ramjack in Wareham was the only one that directly and successfully addressed the problem with a reasonable price quote. Work was done professionally, timely and as described in the proposal.
The RamJack people, from estimate to job completion, were as professional and as detail oriented as I could have hoped for. Great job. Absolute 5 Star.
I had a great experience. Initially, the quote was unrealistic for the job, but after having them rereview and providing a different company’s quote, they were very apologetic and provided a more accurate number and then price matched. Communication was great and they were professional. The work done looks good and they explained everything very well while working. I worked with Matt and Greg who were very nice and helpful.
They were professionable from start to finish. The two gentlemen who did the work explained every step as they did it and were very neat.
