Key Waterproofing Construction

A homeowner's sump pump quit in February, and Key Waterproofing had someone at the house within the hour — for a pump the company hadn't even installed. That is the shape of this Holbrook outfit: wet-basement work, done fast, at prices customers keep calling fair. The work itself is narrow and consistent. French drains, interior drainage channels, sump pumps, and full basement and crawlspace encapsulation account for nearly all of it, with basement inspections making up most of the rest. Angi rates the company 4.7 across 197 ratings — 89% of them five stars, with about 3% sitting at one or two — and the same names surface again and again across years of those reviews: Wendel Toussaint running jobs on site, along with Stephen and Ed. Reviewers describe jackhammered floors, plastic sheeting taped up before the dust flies, and crews that clean up behind themselves. One thing worth knowing about that 4.7: the HomeAdvisor listing is a byte-for-byte copy of the Angi one, right down to the same 197 ratings and the same review bodies in the same order. It looks like two sources agreeing. It is one. The company's paperwork tells two stories that don't quite line up. Angi credits it with 12 years of experience, while the BBB file records the business as started and incorporated on 1 January 2020 — six years. The BBB also lists it as a corporation with one employee, President Wendy Toussaint, which sits oddly against a review history full of multi-person crews and a project manager. The Massachusetts trade licence the listing shows, 217612 with a December 2027 expiry, is self-reported to Angi rather than confirmed against the state registry; the BBB profile carries an A+ rating, though the same page states the business is not BBB accredited. If you have water coming into a finished basement and want a drain system in quickly, this is the kind of shop that answers the phone. Before signing, ask for licence 217612 in writing and check it against the Division of Occupational Licensure, ask how long the company has actually been trading, and get the warranty terms — several customers mention a warranty certificate — on paper.
