How much research have you done on the parts of homes that are salvageable?

We have sometimes donated to Habitat for Humanity and other similar organizations when asked to by clients. There are too many times that the demo items may not meet current code to be reinstalled into a home, thus trying to save something that can't/shouldn't be used beyond a decoration is too costly for us to slow down our demo time. We have sometimes said that if it is needing to be saved, someone else can remove it at no charge to us, the builder. So yes, there is some "salvagable" material that goes in the dumpster.

Depending on the materials that were used to build the house, much can be recycled, especially if it is an old house with vintage details. There is quite a secondary market for commercial  buildings too.

I have not done a lot of research for donating building materials.  When I remodel homes, I do my best to deconstruct carefully to salvage anything worth saving.  Hardware, doors and fixtures are usually what gets saved, although some lumber can be reused for some of the work.  I do not have many places that take donated materials, but I always thought it would be nice to get a warehouse for local builders and be able to sell salvaged materials and donate proceeds for Habitat or other non-profit organizations that support housing for people. 

Mold Test USA is a mold inspection and testing company located in 46 states. We do not perform the mold removal, demo or build back. We act on our clients' behalf and are their personal consultants throughout the entire process from start to finish. The only possessions that are not salvageable are the couch/chair and mattresses. I have never spoken to a remediator that would ensure either item. Everything else can be cleaned unless deterioration had already begun. The purpose for mold is it deteriorates organic material. That is its job. The longer someone lives with mold the more damage it can do to not only your health but your possessions as well.
