My wife and I met with Roger Ergang from Coastal windows and could not have learned so much information on windows as we did. He was thorough, answered all questions and was very easy to talk with. If you want to spend your money right, find a company like coastal to take the time to explain everything in detail. It truly makes a difference in understanding the products. He represented coastal well and did a fantastic job to help us learn everything about windows.

Roger and Christian came out to discuss a project and were very informative and thorough. They were a pleasure to be around, personable. I appreciate the time they invested in addressing questions I had. While I haven't made a decision yet, I look forward to following up with them when the time is right.

Very impressed with the knowledge and how respectful of my home Rob Doherty was. On time took his time to explain every aspect of the renovations I wanted done. And he likes dogs! I’m looking forward to working with Rob and Costal. windows and exteriors.
