This is our second job working with Coastal Windows & Exteriors as the first time around we had a great experience from start to finish. This time we worked with Brendan, Erik and Patrick. They were all extremely professional and wonderful to work with and we are really excited for them to help us bring our vision to life for our home. I would highly recommend this team to any family and friends of ours.
