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.

"We purchased our house last year newly renovated. Unfortunately, they did not upgrade the door. We had probably the worst, builder grade door you can imagine. You could see the light coming in around the frame, the door would be hot or cold to the touch and it did not shut properly. To top it off, it had no dead bolt!My husband and I were very impressed with the entire process of Coastal Windows & Exteriors. We met at our home with Donna, who helped us choose the right door for our space. Once the door was installed it looked exactly as described, if not better.The installer, Mike, did a fantastic job. You can definitely tell that this door was not purchased at Home Depot or Lowes, and was installed by a professional.The door shuts tightly, has an amazing color and comes with a lifetime guarantee.The service of Coastal Windows is definitely worth the price and I would recommend them to anyone!"

"I had my windows replaced by Coastal Windows I Exteriors, Inc. in December. They delivered on every aspect of the process and communicate with me every step (ordering windows, installation dates, etc. of the way. I chose them from recommendation on Next Door. The installers were prompt, friendly, efficient and respectful of my property. The finish work and chalking around the windows were expertly done. They were nice to my dog too! The windows are amazing! I see a big difference in noise reduction and temperature. I have a room that was converted from the garage and it was always so cold. Huge difference with the replaced windows and slider!! The lifetime warranties are great too!. I am so thrilled with new windows. I didn't even mentioned how easy to clean they are too! I am completely satisfied and would highly recommend Coastal windows. Jan Brophy, Portsmouth NH"

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.
