Stateline Masonry & Waterproofing

Stateline Masonry & Waterproofing works out of Waltham, handling the structural work homeowners call in when water starts finding its way into a foundation or a set of steps starts crumbling. The company says it's been at this since 2005, describing itself as locally owned for over two decades, and its stated service area stretches across the western Boston suburbs — Newton, Watertown, Cambridge, Belmont, Lexington, Framingham, and Waltham itself. The thread running through its Google history — 115 ratings, all five stars — is consistency: roughly 78 reviews have piled up across four sources since 2024, and the last six months haven't broken that pattern, with four new reviews and none of them negative. This spring, one customer credited the crew with waterproofing a basement and installing a french drain, calling the outcome exactly what they'd hoped for; another described William's team turning a rotten deck area into a new patio over just a few days, singling out how carefully the finished alignment was handled. A third reviewer this year called the pricing reasonable and the turnaround quick without any drop in quality. BuildZoom independently scores the company 97, and its Massachusetts home-improvement-contractor license (HIC #213297) checks out as active with the state — a detail worth confirming for yourself before signing anything, but one the registry backs up. Nothing negative shows up in the recent reviews, and the pattern holds across more than one site rather than a cluster of ratings on a single platform. For a homeowner, this reads as a company built around foundation and basement work — french drains, waterproofing, the masonry repairs that keep water out — rather than general remodeling. If the job is a wet basement, a crumbling patio, or a chimney that needs rebuilding, the reviews say this is where they're strongest; for anything further afield, it's worth asking directly since nothing here speaks to it.
