We're super excited about having them installed and know that this will benefit us with utility bills and the value of our home. I would HIGHLY recommend having Coastal Windows & Exteri...Read more

Michael Cinelli was the salesperson who came to my house. He was exactly on time was courteous and explained everything to me. I liked the fact that he did not speak I'll of other companies and their products as another salesman from another company did. It was a pleasure working with him.

Mike and Rob came out to give us a quote and we figured out we have a hole in our roof. They helped us to get a resolution quickly. Very thorough and easy to deal with. We were away when the work was done, and they contacted us about finding some additional damage that needed more work. Price was reasonable, and they threw in one item for free. Will definitely use them again and would recommend them to anyone needing roofing or siding work.

We got off to a slow start. One salesman refused to share the quote he'd built. The next one gave totals but not details. Then Mike Cinelli took over, and we have been very happy with the sales process ever since. Mike has been thorough, transparent, and patiently worked through every detail. We are spending 10% of our home's value on new siding and windows, and we want it done right. He returned with a foreman to walk through every detail in the design, as many of our old and rotting custom wo...Read more
