We have countless examples of salvaging building materials , as well as estate furniture, lab fixtures, commercial offices, and everything else imaginable. Here is one example. Last year for a house renovation , we managed the recovery of about 5,000 square feet of flooring, along with interior trim ,doors and windows. Some material, such as the 3″ oak pictured below, was sold directly from the jobsite. Other material was donated to materials reuse stores, and some was reused onsite by the owners.

This is only some of the flooring recovered .
Some of the thousands of linear feet of Polar trim and molding recovered.
Interior and exterior doors all saved for reuse ,as well as exterior shutters
Somewhere in the order of 60 windows saved for reuse.
