Ron Dulmaine & Sons Garage Doors of Cape Cod

One customer summed it up simply: "I'd add a 6th star if I could." That's the kind of line that keeps showing up for Ron Dulmaine & Sons, a family garage door business that has worked out of a Sandwich showroom since 1987 — three generations deep, per the company, starting with Ron Junior and later joined by sons Jason and Sean. Its Massachusetts home improvement contractor registration is active. The ratings back it up across every platform: 5★ on Google from 40 ratings, and 5.0★ from 62 ratings on both HomeAdvisor and Angi (the identical review set, mirrored across both sites). The specifics that show up again and again are speed and small-job follow-through — a 2024 reviewer called at 9am, got a callback within 20 minutes, and had the repair finished by late morning; another described a technician catching a failing spring before it broke outright. On bigger jobs, a 2018 review described the crew templating a custom door to match curved window openings exactly, and a 2023 customer had three doors replaced by installers who showed up on time and worked efficiently start to finish. Staff get named specifically and often — Jason in the office, Sean and Aiden on installs — which lines up with the family-run description, and several reviewers mention hiring the company more than once: one HomeAdvisor review from a customer since 1988 lists openers, springs, and cables done over the years. Not every review carries that kind of detail. A handful are one-line ratings — "took care of everything," "installation was fine" — that confirm a good outcome without saying much else, so the fuller accounts above are doing most of the work here. This is a solid pick for anyone on Cape Cod or Martha's Vineyard needing anything from a standard steel garage door to a custom carriage-house or wood design installed, repaired, or serviced — the license is current and the review history across platforms stretches back to at least 2016. It's worth confirming current pricing and scheduling directly, since neither comes up in what customers wrote.
