JWG Building Restoration works on brick and stone buildings around Boston — the kind of masonry and waterproofing job where getting it wrong just means the water finds its way back in. The Acton, MA company says it has been doing brick and stone restoration, tuckpointing, sealant work and waterproofing since 2013, serving homeowners and commercial property managers across towns including Cambridge, Newton, Everett and Waltham. The written record is thin but consistently strong. Google reviews average 5 stars across seven ratings, and the company carries an A+ accreditation with the Better Business Bureau and no complaints or government actions on file. In a 2025 Google review, a homeowner described a long-leaking cinderblock wall that finally got fixed — re-pointing and sealing work that held up dry for months afterward. A property manager's 2023 review calls the company a repeat vendor across several associations, pointing to clear proposals and steady communication on waterproofing and masonry projects. The one sour note on file is old: in a 2015 HomeAdvisor review, a customer said JWG never circled back with a promised estimate. It's an isolated, decade-old account, but worth asking about response times while you're still getting quotes. For an aging brick or stone building — deteriorating mortar, a leaking foundation wall, a parking garage or monument in need of repair — this is squarely the kind of work JWG's record points to. Confirm current availability and turnaround before booking.
Professional service, with great attention to detail. Very good with bricks, windows, grout, stone, caulk.
We've had a leaky cinderblock wall that finally was remedied by JWG. Justin was great with communication, and Jordan's work on the wall (re-pointing and sealing) was perfect. It's been several months and not a drop of water. 5 stars is not enough!
