Often considered for: Patios, dens, dining rooms
Before you choose
Allow room for the full swing and furniture placement. Confirm active-panel side, bolt operation, screen options and the clear passage with one panel open. Exterior assemblies need a threshold and drainage detail suited to exposure.
What changes the quote
Pair width, swing direction, active panel, glass, multipoint hardware and threshold work affect scope.
Measurement and preparation
Photos and approximate width and height help start a conversation, but are not ordering dimensions. A site survey checks the opening at several points, squareness, frame condition, wall depth and safe access. Tell us about leaks, sticking or previous repairs before a final specification is agreed.
Installation scope
Agree whether the existing frame stays or the full assembly is removed. The written scope should explain protection of the room, removal, support and fastening, water management, insulation, interior and exterior trim, disposal and final operation checks. Hidden damage discovered during removal needs a separate agreed response.
Care after installation
Use the selected manufacturer’s cleaning and lubrication instructions. Keep seals, tracks and drainage paths clean, inspect exterior joints and check locks periodically. Avoid abrasive cleaners and blocked weep holes. Report new leaks, difficult operation or damaged seals rather than forcing the hardware.
