DiggersList is a brand new Web site focused around construction and home improvement projects. It's something of a Craigslist, but with a narrower focus.
The free site, which appears to be funded with advertising, allows contractors, suppliers and DIYers to buy, sell and trade excess building supplies and materials. It also offers the opportunity to post competitive bids for jobs and service.
The site currently serves 15 heavily populated markets in the United States, but expects to expand rapidly. I did a quick search on the Houston site and found a number of appliances, cabinets, tools and lawn equipment available. Could be a nice way for DIYers to pick up some low-cost tools and materials, and maybe even keep some perfectly useful stuff from winding up in a landfill.

This idea is so simple and so timely. I’m a contractor in Dallas where there are mandates from several cities requiring us to recycle and thus reduce our waste from projects (my specialty is tiling). This is a great site to help me stay within regulation. I hope it continues to grow.
This is a good site for interior designers too! We end up with high quality samples that we can sell on DiggersList. Nice post Jeff, I’ll spread the word!
