Foundation expert waterproofing and masonry

Foundation Expert Waterproofing and Masonry works out of Cambridge on the jobs that start below grade — a wet basement, a foundation that needs attention, and the masonry and exterior work around them. The company describes itself as family run, says its owners work directly on jobs rather than supervising, and advertises more than 60 years of experience. Its Massachusetts home improvement contractor registration, #213299, is active on the state registry. Angi lists the same trade licence number and shows a 5.0 rating from three reviews. Those three, all posted in 2025, stay close to the same kind of work. One homeowner hired the company across a newly bought property: the brick chimney repainted, a sump pump installed, the basement waterproofed, and new roof and siding installed. Another wrote simply about "5 star service on waterproofing my basement." A third described a roof repair and called the crew efficient and professional. If your problem is water in the basement or a foundation that needs shoring up, this is the kind of small, hands-on outfit that will also pick up the chimney and exterior work around it. Before booking, get each piece of the job scoped and priced in writing, and ask for a certificate of insurance and a couple of references from recent jobs nearby.
