Verified record
Watertite Foundation Repairs is Tom Welch's crack-injection operation out of Leominster, and the pattern across three dozen reviews is remarkably consistent: he calls back fast, shows up on short notice — including weekends and Sundays — and the basement stays dry afterward. Its written record runs from 2021 through late 2025, all five-star, and it isn't just repeat praise for the same job. One customer had been quoted $23,000 by another company for a leak around a septic pipe before Tom fixed it for a fraction of that, in a 2025 review. Several describe redoing a previous contractor's failed repair — one review explains the earlier crew injected material straight into the crack instead of at the correct 45° angle, in a 2025 review, and another had a years-old repair from a different company redevelop a leak that Watertite came out the same day to fix, in a 2024 review. On a full-length vertical crack homeowners feared would need major excavation, in a 2024 review, Tom's interior injection method solved it in about two hours. The oldest durability check in the record: a customer whose basement had leaked and damaged a finished wall reported, 1.5 years after Tom's repair in a 2024 review, that it stayed dry through a summer of heavy storms and a torrential thunderstorm. Honesty shows up as its own theme — in a 2023 review, a homeowner called about a concerning crack and Tom told them it didn't need injection service at all, then walked them through fixing it themselves, and another 2023 review describes him driving out to check a house with no active crack and giving free mitigation tips anyway. Repairs mentioned in the record come with a lifetime, transferable warranty. There's nothing negative in the written record to flag. The company's own site says it does crack injection and waterproofing across Central Massachusetts and Northeast Connecticut. For a leaking or cracked foundation, Watertite's record is about as strong as this kind of specialty repair gets — just confirm who'll be doing the work, since one review names a different technician than the rest of the record.

“It's been 1.5 years since Tom from Watertite injected 3 window-to-floor cracks in my basement walls (one of which had previously leaked and did significant damage to a finished wall). Basement is still dry.”
Tom was very professional and efficient with his work. I had called him as I had a water leak coming in the crack around my septic pipe in my basement. I had been given an outrageous price of $23,000. to fix this before calling Tom. Luckily I looked on Watertite’s website and they showed exactly what I had going on. Tom came a few days later after calling and repaired the crack. Now I have a peace of mind and a life time guarantee of my house. I can’t thank Tom enough. Lisa B Bloom, West Townsend, MA
On time, easy to work with, reasonable price, and very clean repair. I like the warranty which is transferable to a new owner.
Tom came on short notice and was very professional and engaging in diagnosing the scope of repair on our foundation. I explained that we had crack that was repaired by the previous owner of our house that was leaking and Tom came out the next day to repair the leak. It turns out that the original repair was not done correctly because they injected the material straight into the crack instead of at a 45° angle. Tom repaired the crack correctly and quickly, leaving no mess and for a reasonable price. Would highly recommend Tom for repair service.
Tom is terrific! He filled two cracks in the basement foundation of a property we're selling. His work is top-notch, highly professional, reasonably priced, and comes with a transferable warranty for the lifetime of the property—which will come in handy for the new owners. I highly recommend him!
Tom came out to repair a bad leak in our garage foundation. I couldn't be happier with the repair. He was clean, fast and kept constant communication. I highly recommend!
