Classic window specialist Inc

Classic Window Specialist Inc, based at 197 Durnell Ave in Boston, restores old wood windows rather than replacing them — sash repair, glass replacement, and weatherstripping are the company's stated focus. Roberto A. Santos founded it in 2007 after starting small, and he's still the one running the crew that shows up to your house. This spring, reviewers keep describing the same kind of visit: Roberto and his team swapping cracked panes and a broken chain weight, explaining the fix in plain terms, and leaving windows that look and operate like new. One recent review describes rotted sills fixed and a door handled in the same stop. That pattern sits on top of a Google rating built from 30 ratings, all five stars, and a matching 5.0 across 25 reviews on Birdeye — no negative reviews turn up anywhere in the last six months, and the run of five-star reviews stretches back at least two years across both platforms. Its Massachusetts home-improvement contractor license is active. Because the focus is restoration rather than new-window installation, it's worth confirming your job — full sash restoration versus a simple pane swap — matches what they actually do before booking, since that's the specialty their own site and their reviews both point to. For an old Boston home with wood windows worth saving rather than tearing out, this is the outfit customers keep naming by name. Ask about timing for your specific repair, since none of the reviews mention how far out the schedule runs.
