Zen Windows Boston LLC

Zen Windows Boston is the local face of a national window-and-door replacement franchise — the company says it was founded in 1998 and has grown to multiple U.S. locations, including Boston, all built around one pitch: get a quote online, skip the in-home sales visit, and pay only once the job is finished. The name covers real history in the area. A run of Houzz reviews from 2014 through 2017 describes Matt Rotondi, running the Winchester-based operation, personally walking homeowners through jobs of a dozen-plus windows — replacing 17-year-old triple casements, 27-year-old double-hungs, a French door swapped for a picture window — with reviewers repeatedly naming him for being responsive and hands-on. More recent Google reviews, from 2024 into 2025, describe similar work: 21 windows replaced in four days with SoftLite Classic Pro product, installers showing up on time, and pricing competitive against other quotes. Two things are worth sorting out before signing anything. First, the Better Business Bureau's current listing for Zen Windows Boston is a Brookline-registered entity that's only 3 years old, carries an F rating, and states the reason as a failure to hold a required competency license — even though the same page also prints a license number set to expire in 2028. That's a different registered business than the Winchester shop tied to Matt Rotondi's Houzz history, and it isn't clear which one would actually handle a new job today. Second, a homeowner writing in November 2025 described signing a contract at the end of July with a written 4-to-6-week installation promise, only to have the date pushed to mid-December — nearly five months later — with the windows still not in. That delay complaint sits alongside otherwise steady praise: a 4.8-star average on both Google (26 ratings) and Thumbtack (23 ratings), a 5.0 average on Houzz (12 ratings), and a background-check badge on Thumbtack. One Google reviewer also described getting an old window replaced under warranty years after the original purchase, even after "their local affiliate went out of business" — itself a hint that the local operation behind the Zen Windows name has changed hands before. Zen Windows Boston is a reasonable call for a straightforward window-replacement project sold through its online, no-sales-visit process — the installation work draws consistent praise when it happens on schedule. Before booking, it's worth asking directly which entity is doing the work, confirming its license status independently, and getting a firm, written installation date given the delay on file.
