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.

Reviews
★★★★★
"Coastal Windows installed a sliding patio door for us last November. Two other companies had dropped the ball, and did not provide or install a door. Coastal Windows not only followed up, they got the job done when they said they would. My daughter's comment after the new door was installed was that she thought patio doors were always drafty. The new door is not, and it is due to the high quality of the door and the professional installation. I would recommend Coastal Windows unconditionally."
★★★★★
"Coastal Windows & Exteriors installed a beautiful new front entry door and a new sliding glass door for our home. We are so pleased with their top quality products and their installation team was extremely professional and knowledgable. Will definitely recommend them to friends and family!"
★★★★
"Going back for seconds to have our second floor windows done after our first floor windows/slider a couple of years ago"

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.
