A thorough repair by a sash window professional is a meticulous procedure. It includes more than just a lick of paint; it is a structural and mechanical overhaul.

Old paint layers-- which frequently include lead and hide rot-- are removed away. Experts use specialist techniques like the "Window Care System" or resin repair work to combine soft lumber instead of changing the entire piece.
