We were in a difficult situation with a leaky roof after prior year ice dams causing damage to roof and gutters. We contacted Coastal Windows and Exteriors and got rapid response and a solution to our problems. We have had bad experiences in the past with other companies but Coastal was amazing. Great communication, respect for our needs, and timely “as promised” service. Everyone was professional from the owners to the installers. The Installers were polite and very neat. Our neighbors were amazed at the efficiency and quality of the job. This was a big job on an old house with winter bearing down on us and everything went beyond expectations. We couldn’t be happier and plan to use Coastal Windows and Exteriors for our future projects.
