Kittery, ME · Local Install Crew
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
★★★★★
"Met with James Faro at our house to look into a new roof and was blown away by him as a sales person. He was knowledgeable, professional and incredibly friendly. We met with another company to redo our roof and after meeting with Jim from coastal windows and exteriors we could never go with anyone else. Bravo to this company for hiring the right people for the job!"
★★★★★
"I received a presentation and proposal by Terry and Tim to replace some windows in my home. Both Terry and Tim were very professional and pleasant to deal with. They provided excellent information on the products they use and the process to replace the windows."
★★★★★
"Just met with Jim Faro from Coastal Windows & Exteriors. Jim was very professional and informative. No high pressure sales tactics and provided great insight and alternatives to what I was looking for. Will definitely recommend."

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.
