Remodeling in Westchester
Westchester's guides cover the whole county, where 52%1 of homes were built before 1960: prewar Tudors and colonials, then the postwar houses that followed. Permits come from your own city, town or village, and the plumbers and electricians who file them need a Westchester County license.
