Reviews
What homeowners say about our Vinyl Siding
★★★★★
"Great experience today with both Mark and Carter getting an estimate to replace the siding/gutters on my home. They were both very pleasant, professional, and very thorough. They explained every aspect of the project which put me at ease."
★★★★★
"We decided to move away from the wood shingles on our home, which required constant repainting, and invest in a more durable option. From the moment we met Frank Camarda from Coastal Windows & Exteriors, we knew we were in great hands. He took so much time with us, carefully walking through all of our options and making sure every single question was thoroughly answered.We couldn’t be happier with our decision to move forward with James Hardie siding, and we were especially impressed by the beautiful design Frank created and showed us during the meeting. His knowledge, patience, and attention to detail made the entire process feel exciting and stress-free.We are thrilled that we contacted Coastal Windows & Exteriors and truly cannot wait to see our home transformed. I highly recommend Frank and his team to anyone considering a siding project. Their customer service, product selection, workmanship, and design guidance were all absolutely outstanding."
★★★★★
"My siding suffered some damage during a winter storm. Cody from Coastal Windows & Exteriors inspected everything and gave me all my options to repair it. True professional, thank you Cody."

Cost
How much does Vinyl Siding cost in Portsmouth, 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.
