My daughter called 1-800-JUNK when she was helping us clean out our basement. It was $500. But they took everything, including old chemicals and moldy stuff and old furniture. We had a huge truckload they hauled away. I didn’t pay for it so the cost wasn’t an issue for me.
There’s a professional organizer that did a presentation at our guild. The idea of going through my stuff and figuring out how to get rid of it seems very overwhelming. I think it will be someone else’s problem after I’m gone. If we decide to move, I’ll be forced to deal with it.
