Window Working

Greg Besher runs this one-person window repair shop in Boston, and the thing people call him for again and again is fixing an old double-hung window that someone else said couldn't be saved. He works on repair only — no full window replacement — and reviewers describe him going after antique sash windows other companies wouldn't touch. A January 2023 review describes him refurbishing historical windows in a Back Bay home; an October 2023 review says the same about a window in an 1874 house; and in July 2023, one customer had him rehabilitate three original windows that had been pulled out and stored in the basement, calling it "not a standard job." More routine repairs show up too — foggy double-pane glass swapped out in April 2026, a broken window fixed the same afternoon it broke in April 2025, and in March 2024, a customer said Greg fixed two windows in 15 minutes that their contractor had called unfixable. Not every account is this smooth. In an April 2025 review, a customer said Greg failed to fix the window they'd hired him for and disputed the scope of work they'd agreed to. Two older reviews describe worse: a December 2021 review says he stopped responding to texts after agreeing to schedule a visit, and a 2019 Angi review describes no-shows and shoddy work. Greg's own site says he's been fixing windows for "over 3 years," which sits oddly next to a review history that runs back to 2018 — worth asking directly how long he's been doing this specific repair-only work. Window Working is a strong call for an old window another company wants to replace rather than fix; given the handful of dispute-driven reviews, confirm the scope of the job in writing before he starts.
