Customer Reviews

I'm having some windows replaced and decided on Coastal because of how thorough and helpful Braeden was. He was consistent without being pushy and answered all of my questions in a timely manner. I like that Coastal is local and believe in the community aspect of the company.

Dino took the time to come back out a second time so we could walk around and explain what needed to happen. He even stopped the process to instead focus on the roof (originally I was looking to get an estimate on siding) bc as he explained it was a higher priority. His explanation on what the work would look like was crystal clear. I feel confident about accepting his proposal bc he clearly answered every single concern I had… AND the price is perfect!

Cody and Patrick came and took the time to go over the entire process and verify what I wanted and what I needed.

I had a really great conversation with Ewan and Connor today. Looking forward to working with them. Post installation: fabulous team. My door is beautiful and functional. Every step in this process has been easy. Thank you, Coastal!
