We replaced an aging patio door system with a new triple-pane hinged glass unit at this residence in Chesapeake Beach. Our crew removed the existing door frame, cleared out old insulation, and prepared the threshold to ensure a perfectly level and weather-tight installation. We installed a dark green multi-panel door assembly that provides a sharp contrast against the light grey horizontal siding. This project improved the thermal performance and ease of access between the interior living space and the outdoor deck area.
