Classic window specialist Inc

Classic Window Specialist Inc, run by owner Roberto A. Santos since he founded it in 2007, does something narrower than most window companies: rather than tearing out old windows and replacing them, it restores them — resashing, reglazing, and reweatherstripping originals that are 70, 100, even 130 years old. That focus shows up again and again in Google reviews from owners of older Boston homes, several of them specifically in historic districts like Beacon Hill and Back Bay. The write-ups are unusually specific for an all-five-star record. A 2025 review describes a bay window from a 1940s house re-glazed and repainted; another describes a sash restored to airtight after being "about as useful as an open hole"; a third describes replacing two cracked panes and a broken sash chain weight, with Roberto walking the homeowner through maintenance afterward. Several customers mention using the company more than once, and more than one review calls out fair, itemized pricing specifically — a 2024 review says Roberto "always gives a breakdown of all expenses incurred." Reviewers also describe Roberto as personally responsive under pressure — one 2025 review recounts him fitting in a repair around a customer's upcoming surgery during a busy summer. Recent reviews running into 2026 keep the same pattern, and no negative write-ups appear anywhere in the record. Its Massachusetts home improvement contractor registration is currently active. The one thing worth knowing: this is a restoration specialist, not a general window-replacement outfit — the right call if you have older, original windows worth saving rather than swapping for new ones.
