“Our 1990s colonial was showing its age when we decided to call Coastal Windows & Exteriors last fall. They helped us choose James Hardie Plank in Timber Bark that perfectly matches our natural landscape and stone accents. The installation team was incredible – professional courteous and they treated our home like their own. Ten months later our house still looks brand new and we’ve had multiple neighbors ask who did the work. Our energy bills dropped noticeably and the whole experience was stress-free from start to finish. We couldn’t be happier with our decision to choose Coastal Windows & Exteriors!”
