What homeowners say about our Entry Doors
★★★★★
"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"

"I love my windows and the service was wonderful! If I ever needed any other window or door work I would call them again - and I think that is the best reference that someone can give!!"

Cost
How much does Entry Doors cost in Exeter, NH?
Entry-door pricing depends on the material (fiberglass versus steel), whether you're adding sidelites or a transom, the glass and hardware you select, and the condition of the existing frame, sill, and surrounding framing. Rot repair or resizing an out-of-square opening adds labor. We measure on site and quote the complete installed unit — never a slab-only price that hides the real scope.
