About this product
Premium insulated vinyl siding adds R-value to the wall, resists impact, and never needs painting. Options include Mastic, CraneBoard®, and other VSI-certified profiles — installed by certified crews with a lifetime product warranty. A cost-effective upgrade that looks and lasts far better than the builder-grade vinyl most homes were originally sided with.

"I reached out to Costal Window and Exterior for a roof replacement. I had an appointment with Jim Faro the next day. Very professional, took measurements and showed me every layer of new product that would be going on my roof once they stripped the old shingles and such off. All in the same visit. I was given two quotes for my roof as I was unsure how big a project I wanted to make it. Jim worked with me to make sure I got what I wanted is working with me still to make sure my new roof goes on ASAP and I have some pretty bad damage from recent storms. I highly recommend Jim and Coastal Windows, I will be returning when its time to do siding!"

"ADDENDUM: The siding is done and what a great job! The crew were friendly and professional, got the entire house resided in under a week! When they were finished, there was a slight adjustment we wanted, and they came back and handled it in an afternoon. Fantastic work! We've gotten numerous compliments on how our house looks now.We were looking to get the siding replaced on our house. We had two companies take a look and both gave about the same estimate, but Coastal went above and beyond to help us make it happen. When we weren't sure how we could afford it, their representatives pointed us toward refinancing, gave us contacts to get it done, and made sure we were okay every step of the way.But beyond that, they're also just incredibly friendly while still maintaining a great professional attitude. Tim and Terry were our representatives, and they made us feel listened to. They heard what we wanted, and helped us find a way to make it happen. When they left after our first meeting, we actually knew we could get good siding that would protect our home for decades to come and look nice doing it, and we wouldn't be drowning in debt afterward."

"Our experience with Coastal W & E has been wonderful! From the time my wife made the contact phone call- a live, professional, pleasant, person answered the call and set up an appointment for the very next day, to meeting Tim and Terry. Tim and Terry measured our home for siding and discussed our options, the process, and pricing. They explained everything completely and answered all our questions. They made it so easy! We also decided to update two windows. We met Joe when he came to measure the windows to ensure a smooth installation. He was a very nice gentleman and we feel confident we have chosen the perfect company to address our home's siding needs!"

Cost
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.
