Crawl spaces are always an interesting mixed bag of fun. It is the last thing I do on a house. I like to run all the water in the house and then do the crawl space to be able to see if anything is leaking in the crawl space.
Once I inspected a house that was half basement, half crawl space. I had everything done and the crawl space was the last item on the list. I put on my Tyvek suit and opened the 2’x2’ door that was in the basement wall adjoining the crawl space. The door sat about 5’ off the floor so I had my step ladder. Door open, up and into the crawl space. I slid down into a sea of beer cans! Half of the crawl space was filled with empty beer cans! About 2’ deep. Tyvek suit on, swimming through beer cans to check out the framing and other crawl space items.
The people bought the house and called me later to tell me that they took out four pick-up loads of garbage bags full of empty beer cans. Maybe they made their first mortgage payment.
