“Clyde McHenry’s group took on a real challenge replacing windows at the Madison Office/Hotel high-rise building in downtown Washington, D.C. Restricted noise producing hours and occupied office space made this a very difficult job to manage and perform. Clyde’s group did an outstanding job working with all parties involved to get the job done on time and with no extra costs. I would highly recommend them to anyone looking for new or replacement windows.”
