Design Visualizer

"After an extensive solicitation and review of exterior contractors we settled on GS Exteriors. Settled isn't the right word as they were substantially below the cost estimates of other companies and their workmanship was top notch. We were originally apprehensive because of the price disparity but after interviewing several clients and scouring reviews we decided to move forward with them. One item to note: The man that answered my phone inquiry, Ernest, was the same guy that came to my house and the same guy that coordinated the various work crews that executed the project. With the other companies I interviewed, it seams as though I was working with a pile of other folks dedicated to making the sale as opposed to guys actually coordinating the work.GS Exteriors replaced my existing original panel siding with James Hardy Hardipanel, added a layer of rigid insulation, painted, faced a portion of the front of the house and our chimney with stacked stone, replaced a bank windows, and rebuilt a deck. All of the work was performed exceptionally and in a timely manner in spite of the work being accomplished much later in the season (Fall/Winter) than most companies work. We couldn't be happier and continue to receive compliments from neighbors on how great the house looks. Highly recommend these guys!"
