Window Restoration

WINDOW RESTORATION

Total restoration of existing sashes, frames, AND single pane glass

Restoration is recommended when there is significant decay of the wood elements, the glass is loose, or more than one third of the putty is loose or missing. When all other hardware, weather stripping, or pulley and rope problems are presumed present to a degree, they are corrected as part of the sequence of sash restoration.
