New Castle Building Group, Inc. Reviews

"We now have beautiful new decks with a Trex steel framing system topped with Trex decking, rails, and lighting. Along with a 25-year warranty, we will no longer have to deal with deteriorating lumber or carpenter bees boring into a wooden frame. We couldn’t be happier with the outcome."


“Jason is a true craftsman and artist when it comes to deck construction, outdoor living, and outdoor kitchens! The materials that New Castle uses are always the absolute top of the line, and they never skimp on any details.”


“There weren’t any surprises. They were here working every day, and they cleaned after themselves. It was a good experience overall.”


“He is a true tradesman and excellent at his craft. His work is clean and precise, and we love our new deck!”
