Customer Testimonials

After purchasing our first time home. We had the pleasure of working with Ewan. He had great customer service working with us and gave us a reasonable/ honest quote. He answered every question my girlfriend and I had with fair points and great detail. Ewan is a very knowledgeable sales rep who also takes great pride in his work. I look forward to working with him in future projects we need done. Would highly recommend him to anyone.

We had all of our gutters and spouting replaced by Coastal. Roger was a very responsive sales representative and took time to come to our house, understand what we wanted, and talk through options before providing a quote. In stark contrast to others who just slipped a quote into the mailbox. We are very happy with the job and hope to use them again in the future.
