What homeowners say about our Vinyl Siding

★★★★★

"Worked with Braeden to get what we needed to get the siding done to our house. He answered our questions, was incredibly approachable and honest. He explained all aspects of the work that would be done and how it would be accomplished. Explained the training the installers undergo and the history of the company. We feel incredibly fortunate to have found them and him."

"We recently worked with Coastal Windows & Exteriors to have our siding, roof & gutters replaced. We met with Ryan who was terrific, very professional, thorough, detail-oriented and low pressure. Can’t thank him enough for all the time he took to make sure all aspects of the project were covered to our liking in the contracts. The teams that were sent to do the work were great, very polite, courteous and hard working. They would show up every day (weather permitting) promptly at 7am and work until dark, always cleaning up any debris at the end of the day. The finished product looks great and we're happy with the transformation."

"What a fabulous experience. We had Coastal out twice to discuss siding on our home. The first visit Frank and Cody (I think his name was Cody. If not I’m so sorry!) came out conveniently after our long work schedule. They were super informative, answered all of our questions and, most importantly, didn’t make us feel rushed regardless of the later hour. Frank’s no BS style was exactly what we were looking for. We want up honest conversation not sugar coated scripted speeches and he delivered. Neither one of them made us feel pressured and they were extremely professional during my husband’s “negotiations.” The way you can see what your house will look like on the computer is also a plus since I’m a visual person. I was thankful for that touch. We planned to hold off until spring but came across some issues that pushed us up much further. Frank, again, met us at the house same day and we finalized our options. He was honest when answering my last few questions and they welcomed us to the family. They will have everything handled from here. We are very much looking forward to having this project done and highly suggest having Coastal out to your home even if you are unsure what it is you are looking for."

Cost

How much does Vinyl Siding cost in Dover, NH?

Vinyl siding cost tracks the wall square footage, the number of stories, how much trim, soffit, and fascia work is included, and whether you choose foam-backed insulated panels or a standard profile. Removing multiple existing layers or repairing sheathing adds labor. Every number we give comes from an in-person measure — no square-foot guesses over the phone.
