Bailey Michaels on Harborline Exteriors

I couldn’t be happier with the work done by Harborline Exteriors, They replaced three of my problem windows as well as my front door! This was all done while they were building me a Back Yard Pergola with an outdoor kitchen. Their professionalism and attention to detail were top-notch. They stayed on schedule, kept a clean workspace, and the quality of the craftsmanship far exceeded my expectations. Highly recommended!!

Once again, Bill Bowen and Harborline Exteriors do not disappoint. From the moment I called this company to the finished product, I was amazed. Great job! The crew was very thorough, neat, courteous, and the specially-ordered window looks beautiful.

Bill and his team were able to come in on my time and let me design my own Pergola, they were fast and efficient in the build process and handled the HOA approval process! - life saver. They also replaced a couple of rotten windows I didn’t know I had that were leaking cold air for me too.

Lauren Thompson on Harborline Exteriors

Harborline Exteriors did an excellent job bringing our vision of our backyard space to life. We are extremely happy with our new custom built pergola.

Our representative was Doug in the Charleston office and his knowledge and professionalism gave us great peace of mind when we signed up with him for our new windows and doors. He gave us a great price and answered all of our questions. We used the 12 months no interest no payments program and Doug walked us thru the easy process. The install crew was wonderful and the finished product was showroom quality. We highly recommend Doug and Harborline Exteriors.
