Renewal by Andersen's Cape Cod-area dealer, based in Bourne, installs Andersen-brand replacement windows, patio doors, and entry doors, and its written record is enormous — 488 Google reviews going back to 2021, currently averaging 4.9 stars, with BBB accreditation at an A+ grade.
The volume of specific detail is what stands out. Reviewers name a rotating cast of measurers, project consultants, and install crews — Ron, Jason, Ivan, Andrey, Russell and dozens more — and describe a consistent process: an accurate measurement visit, a clear walkthrough of what's about to happen, and a crew that protects the house while working. A 2026 review describes two installers replacing windows across two of the hottest days of the year without complaint; a 2026 review of a full tear-out window replacement calls the installer Andrey thorough and patient answering questions; a 2025 review describes a crew, Russell and Andrea, coming in on their day off and working nearly 11 hours straight to finish on schedule. One customer, on their fourth round of windows and doors with the company, called the crew consistently polite, respectful, and hardworking. Another, in a 2025 review, described Russell and Alex replacing windows and a front entry door with workmanship they called meticulous.
What to know before calling: this is a large, sales-driven operation, and a few reviews single out the marketing rather than the installation. A 2025 one-star review describes a mailer built to look hand-written, calling it deliberately misleading toward elderly recipients; a separate 2025 review flags door-to-door canvassers as "incredibly obnoxious," and another says it couldn't confirm whether a door-knocker was really a company representative. None of these describe problems with the actual product or the install work itself.
For a straightforward Andersen window, patio door, or entry door replacement, the installation side of this dealer has an unusually deep, consistent record — just expect an active, door-to-door sales process on the way in.
