Ryan Mahoney is amazing! He took the time to go over all of our siding options. He came prepared, with all the samples. He walked outside with us and showed us numerous colors in different lighting. He patiently helped us pick the perfect color siding and was able to give us a quote the same day! Throughout the entire remodel, he continuously stayed in contact with us. We couldn't be more happy! Thank you Ryan!! We've recommended you to numerous friends and neighbors!

Roger came to my house to provide an onsite survey of my existing windows with his installation counterpart. I have personally done many in home visits and they were beyond professional & informative. They brought a travel window to show me exactly what I was getting & explained each detail regardless of how much it understood, but it made sense. The product sold itself and I’m very happy with our decision to go with Coastal Windows.

Ryan and Dino have been a pleasure to work with so far. Extremely knowledgeable, thorough, and professional. The planning process has been a breeze, especially being able to see material samples in person to help in decision making. Can’t wait to get started on our home project with Coastal!

Just spent a very productive and informative meeting with Dino going over our options for our James Hardie siding. He was professional, friendly and easy to work with. He helped my spouse work through the best color options and went over, in detail, every aspect needed so that the trim, windows, gutters and finish work would be completed to our satisfaction. We were also able to quickly come to an agreement on price very satisfactory to both me and my spouse . I highly recommend Dino.
