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







About this product

Triple-pane glass with low-E coatings, foam-filled frames, and factory-certified installation cut drafts, quiet the house, and lower heating bills.

"Called Coastal Windows & Exteriors today and Dino and Stephen came out three hours after calling. The only contractor out of the five that I called that came out same day.They were super knowledgeable, extremely friendly, and helped my family select the perfect roof and gutters for our new home.Can’t wait to get everything installed and they are even going to rush the install because we have a few leaks.Top ten service! Highly recommend!"

"My wife and I met with Derek and Gage last Tuesday afternoon to discuss our home window needs. After some light discussion, we toured the house and decided to replace most of all the windows, two sliding doors and our primary entrance door. Derek really knew about their products, he described all of the nuances of what the new Harvey windows offer and explained the precision manufacturing process. Also, he described the door and its strength andstructure, and both he and Gage were very personable. We look forward to seeing the next phase, when the windows and doors become part of our home. I would recommend Costal Windows wholeheartedly!!"

"Just had an estimate so far to install a new window and potentially replace a couple others. The sales pitch is too long, but the professionalism and customer service is otherwise impressive so far. I was contacted by Scott, who was very nice and got me scheduled quickly. Then Patrick called and informed me once Connor was running a few mins behind in traffic, which he truly was all of 5 mins late, and then Connor was very friendly and professional. He spent nearly 2 hrs at my home both talking with me through my project, the options, and ways to make it more economical. That time was partly spent telling me about the company and as he had to call his boss while with me to report back when I would have liked to move on to other things. I was warned their process could take a while upfront, though, and I didn’t walk away feeling pressured to buy."

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.
