Our siding and windows are in bad shape and we knew that both needed replacing. We'd gotten a few quotes from other vendors but didn't feel fully comfortable with moving forward. Braeden and Mark were great, answering all of our questions and making sure we were confident in their teams and what to expect. Can't wait to see how it turns out

Mark and Braeden were extremely detailed and professional during our consultation. I had an idea of what we wanted for our siding and windows and they partnered with us to make it a reality. Taking on such a big project can feel overwhelming but they’ve made it easy. I look forward to seeing the final results!

I met with Bobby to go over my ideas for window replacement and he could not have been more knowledgeable! He went over possible options in great detail, right down to explaining the pros and cons of materials and components. My interaction with Bobby left me extremely confident in choosing Coastal Windows & Exteriors to handle my project. I look forward to the install and other potential future projects!

I had a great experience with these people, they were very friendly and helpful as well. Carter was especially awesome and helpful making the installation process super smooth and affordable. Plus, they even played Rocket League with me and my friends which was super fun. I’d definitely recommend these people for anyone. Overall, they’re professional, reliable, and genuinely care about their customers.
