Triple-pane, energy-efficient windows built for New England winters.







About this product
Every replacement window we install is custom-measured for your opening and sized to the fraction of an inch. Triple-pane glass with low-E coatings, foam-filled frames, and factory-certified installation cut drafts, quiet the house, and lower heating bills. Every window is covered by a limited lifetime warranty and installed by W-2 crews — never subcontractors.

"Extremely professional from start to end. Very transparent about the obstacles we encountered, and used their whole professional team to create work arounds to give us a fantastic product and easy install in a timely manner. We are over the moon about our new windows and buying experience. Much thanks! Highly Recommend."

"Had a great presentation by Derek for some new windows in my condo.Very knowledgeable about the product and the company has been out for exact measurements. Talked to several companies and got the run around just trying to get them to come out.So far very happy with Coastal"

"I reached out to Coastal Windows to have them look at a few older/damaged windows, as well as how to replace a custom "Garden Window Box' off our kitchen area (this too was damaged, old, and one of a kind).A product Specialist (Braeden Kane) came to ur house the next day. He sat with us and provided different options and actually helped us decide on a change (sliding style window) for our front kitchen window. Made sense as we will soon put a Farmers Porch there, and the window will be functional for passing thru items (cocktails?), and not just a window for airflow!!We were also walked thru the levels and benefits of these window types, this helped us with a perfect set of solutions! Next was a very easy visit for the custom measurements, and then they went off and ordered our windows.There were then challenges on a couple of the window styles (custom styles) that Braeden helped us resolve personally! What a nice guy! He scheduled the install around our travel schedule, and that is coming up real soon!!This has been a pleasurable experience........"

Cost
Window pricing is driven by how many openings you're replacing, the size and style of each unit (double-hung, casement, bay, or specialty shapes), the frame and glass package you choose, and the condition of the existing framing. Homes needing rot repair, custom capping, or difficult second- and third-story access take more labor. We don't quote a per-window price sight-unseen — we measure every opening in person and put the full scope in writing before any work begins.
