What homeowners say about our Replacement Windows
★★★★★
"Theo at Coastal Windows has been fabulous to work with. I am in a unique situation where I own property with another family and, after many emails to figure out the best approach, Theo took the time to meet with us all and make sure that all parties were satisfied with the project’s direction. We are just in the beginning stage of the work, but after consistent, conscientious communication with Theo, I totally trust that the project will be a success. I’m sure that I will write another review when the work is completed. Thanks Theo and Coastal Windows!"
★★★★★
"I recently had my house sided by Coastal, I went with James Hardie cement siding. The house looks amazing what a fantastic job that Coastal did. Everyone from sales to the construction crew was so easy to deal with. Financing was so easy and painless.The job was done in the time frame that was quoted to me. The crew cleaned up any debris around at the end of the day. Besides the siding new windows and gutters were installed. My house looks brand new. I recommend anyone who is looking into siding to call Coastal siding and windows you will not be disappointed. It’s a joy to look at my house as I am driving down the street. Extremely satisfied"
★★★★★
"Cody and Mark were great. Extremely informative and professional throughout the entire process. They took the time to cover every base and made sure we fully understood everything without ever being pushy. We really appreciated how respectful they were, especially knowing we were getting multiple quotes. If you’re calling Coastal Windows, make sure you request Cody and Mark. You’ll be glad you did.Adam & Kristina"

Cost
How much does Replacement Windows cost in Exeter, NH?
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.
