My windows are not installed as of yet, but my experience with both Terry O'Connor and Tim Alcott were great. Both were professional, friendly and very knowledgeable. Also, both were very clear in explaining the process, cost, window warranties and timeline. I'm very happy with my purchase and I can't wait to see my new windows!!!!.

We called Coastal Windows & Exteriors to replace the siding and some windows on our house. Tim and Terry were here on time and prepared. They went over all the options and explained every detail.

We love our new windows! We were very happy with all aspects of the process and with every member of the staff at Coastal Windows. The staff were knowledgeable, courteous, and responsive.

We would highly recommend Coastal Windows!
