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.

"Roger and Connor spent hours with us explaining their company and their siding product options . They gave us many choices of product and had samples of siding for us to view and touch.It was very easy to book an appointment with this company , and they took the time to take photos of our house and explain the entire process in detail. I will definitely add to the review once we have a final walk through and include photos. We are already planning on discussing new roofing for the future. I highly recommend Coastal Windows and Exteriors."

"Christos and Cody were very helpful in walking us through the whole process as we planned to replace the windows in our home. They were very knowledgeable, approachable, and responsive to our questions and concerns. Coastal has a great team to work with if you’re looking for quality customer service. Looking forward to our new windows in the coming weeks!"

"I recently had two of coastal‘s trained professionals to my home to give me a quote on a large window siding and roof job. Conner and Bobby were extremely professional their knowledge of the product and the industry was second to none they took at the time to explain to me the background of the company and everything that they offered and then some. They both took the time to explain all of my questions that I had and gave me numerous options of different products and services that the company offered. I ended up agreeing to a large project for my home, and I’ve never been so excited for the end. result, I highly recommend coastal for any of your home improvement needs that they offer. The experience was flawless."

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.
