We had the pleasure of having Coastal Windows & Exteriors install vinyl siding and replace two windows.

Now that everything is installed and com... Read more

The products they offer are by far the best and worth the investment to make our hou... Read more

Coastal Windows is hands down the most courteous, professional, and attentive business we have worked with since we bought our fixer upper. Our initial home visit by Tim & Terry told us everything we had to know about whether or not Coastal Windows was the right choice. They were right on time, knowledgeable, and genuinely excited for the work we were planning on doing together. They have kept great contact with us since, even sending us a personalized handwritten Christmas card. That was awesom... Read more
