"Brendan at Coastal Windows & Exteriors was referred to me by one of my clients. I was looking to have new vinyl shingles install on my home and had already interviewed 3 other companies. I didn't feel good about any of them, so I reached out to Brendan. We met up a few days later, I told him what I wanted, he didn't me rush through the process to get a signed contract. I told him what my budget was, he said he would do everything in his power to stay on that budget and he did. I wanted a yellow house and was told that it was not a popular color but that didn't stop him from trying to find a yellow that I liked. There were only 2 yellows to choose from so he gave me other sample colors and didn't rush me with making a decision. I decided on the color Wheat and I am so happy with the choice. If I had any questions he was always accessible. The crew that worked on my home were professional and friendly as well. Brendan was great to work with. I highly recommend him and Coastal Windows & Exteriors."

"Coastal Windows was very professional from start to finish. The process of choosing what we wanted, taking the time to explain the long term benefits of going with their product and the follow through fast installation, one day, no mess, all clean, in our more custom job. Overall very happy with the service and follow through support. The door is a true investment not only esthetically, but also financially, making a big difference in keeping the heat in."

"My new Provia front door and storm door are beautiful! Dino understood my style right away and we designed the perfect door for me. The door was built as designed and installation was done well. Even more exciting was the replacement of the storm door on the back 3 season porch. We widened the doorway and changed the swing. I am very happy with the quality of the products and the process from beginning to end. I highly recommend Coastal Windows and Exteriors"

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.
