Seaside Windows & Doors

Seaside Windows & Doors — also branded CSIDE — works out of Marblehead, taking on window and door replacement across the North Shore, from Salem and Swampscott up through Beverly, Peabody, Lynn, and Rockport. The company says it's been at this since 2014, and reviewers keep naming the same person running the jobs: Andy, who by several accounts explains the options, quotes fairly, and shows up to install what he sold. Its site lists ENERGY STAR®-compliant windows as the product line. Every review that surfaced is a 5-star rating on Google — 22 ratings overall, 21 with actual write-ups — and the details repeat: a custom storm door built for an oddly small opening, porch doors and windows swapped out on the same visit, an entry-and-storm-door job finished in Beverly without a hitch. One customer names the brand — Marvin — and says the new units cut down noise as much as they improved the view. Several others describe a tight turnaround, quote to install in about a week, and crews that clean up before they leave. Worth noting: all 21 of those reviews landed within about five weeks in mid-2026, so the online track record is much younger than the business itself claims to be — there's no earlier review trail to check against. One review also mentions a $50 fee to schedule the initial assessment; it isn't clear elsewhere whether that's standard practice or gets applied to the job cost. For someone in Marblehead or a nearby North Shore town replacing a handful of windows or a door — especially anything oddly sized or a specific brand like Marvin — this is a small, owner-involved outfit with a clean recent run. Ask directly about that assessment fee and, since the review history is so fresh, request a couple of direct references from earlier jobs before booking.
