From soup to nuts, Coastal outperformed, out bid, and continues to support our project for new windows on our lake house. The price was negotiated, the design agreed upon, and installation was on time, neat, and the workers, professional. Outstanding!!!!

From the beginning to the end my family was pleased and impressed with the process. (Family owned and customer satisfaction taken very seriously). They went above and beyond for our old home. Make sure to call them and include them when doing estimates, I bet you will choose them. I had 4 companies come by and Coastal out shined them all.

This is our 2nd time working with Coastal Windows, and each experience has been an absolute pleasure. The professional staff comes to the house and listens to our needs and provides helpful suggestions. Even the installer who comes out and does the final measurement is super. Very courteous and the quality of the product is excellent. It helps that their pricing is very competitive, and if we have future needs to improve our home Coastal Windows & Exteriors will be our first call.

Coastal Windows & Exteriors replaced my roof. They met with me and discussed options and pricing. About a week after signing the contract, we had a big rainstorm and I had water running down an interior wall. I called them and they were there within an hour to tarp the roof at no extra charge. When they did the replacement, it was done in a day. They left my house and yard cleaned up and the roof has been excellent.
