Some sources for used windows and doors include classifieds sites such as Craigslist.org, auction sites such as eBay.com or specialty used building material resale stores as of 2015. Some local organizations also specialize in reclaiming doors, windows and other supplies from demolition and renovation projects to sell or donate to local builders.
Craigslist.org features multiples sections that may include listings for used doors and windows, such as its general For Sale section. The site does not offer a specific category for building supplies, so users need conduct a keyword search for the appropriate material and filter options according to category. Used doors and windows may also appear in the Free and Barter sections.
Auction sites such as eBay.com also frequently include posts about used doors and windows covering both contemporary and vintage styles. Listings typically include pictures of the items and descriptions of their condition along with dimensions to ensure they fit with your project.
Another option is to visit a local home construction charity or organization to inquire about building supply resale services, as many entities sell unused supplies to fund future projects. These organizations may also partner with building supply reclamation services to source doors and windows, and they may be able to sell used products as well. Some general building supply retailers also carry small inventories of used products, typically from returns or replacements.
