Mount Vernon Window & Door provides replacement window and exterior door installation for homeowners in Mount Vernon, New York and southern Westchester County. Services cover energy-efficient vinyl and wood-clad windows, double-hung and casement styles, bay and bow windows, picture windows, entry door replacement, and sliding patio doors. Southern Westchester's housing stock skews old, early-century colonials, Tudors, and multi-family homes where original double-hung sashes have long since lost their glazing putty, sash cords, and weatherstripping. Those windows leak heat through Northeast winters and rattle in every storm. Replacements are sized and installed to fit existing openings without disturbing surrounding trim or masonry wherever possible. Homeowners receive a free in-home measurement and a written itemized estimate, with financing options available. Service covers Mount Vernon, Yonkers, New Rochelle, Pelham, Bronxville, Eastchester, and Tuckahoe.
