Typical Greater Boston range for this kind of work, from regional averages — not a quote from Wilmington Window and Door. Use it to sanity-check bids, then get the real number in writing.

Thirty-plus years in Wilmington doing windows and doors, and the paper trail backs it up more than the review count does: Wilmington Window & Door has 28 documented Massachusetts building permits — window swaps, entry and patio doors, composite decks — spread across towns from Burlington to Tewksbury, Lowell to Methuen. The company, run by Keith Brooks and family-owned by its own account, says it has been at this since 1993 (Better Business Bureau puts the start a year later, at 1994, though both agree on roughly three decades). It's been a Better Business Bureau accredited business with an A+ rating since 2013, and calls itself an authorized dealer for Harvey Windows & Doors and Therma-Tru — the kind of manufacturer relationship a window-and-door specialist actually needs. What's thin is the customer record online. Google shows only 5 stars across 4 ratings, and the one review on file — from 2022 — called the work great and said the reviewer would recommend them without hesitation. Houzz and BuildZoom, where BuildZoom's own permit data lives, both show zero written reviews despite the decades of work. A more recent signal: a May 2026 Nextdoor post in nearby Woburn recommended the company by name as honest and fair, unprompted word of mouth from a neighboring town. Before booking, it's worth asking directly about licensing: BuildZoom lists an active Massachusetts home improvement contractor registration under the company's current number, which it says it verified as active this past April, but also shows two earlier registration numbers for the business now marked cancelled — not unusual for a firm this old, but worth a quick check with the state yourself. This reads like a long-running local outfit that does the work more than it markets it — a fair call for a straightforward window, door or deck job, especially with a neighbor's recommendation in hand, though the modest online trail means it's worth asking for a couple of recent references before signing anything.
“Call Wilmington window and door. Local family owned and operated. They’re honest and fair.”
As usual they did a great job. Would not hesitate recommending them to a friend.
