We had a mini-disaster when the water heater in the attic sprung a huge leak...maybe $35K worth of damage per the insurance company. Probably one of the best things to happen RE “cleaning out”. The flood mitigation company came in, boxed stuff up, moved stuff into other rooms for the repair work to be done. Prior to moving things back into place we decided to go thru the 150 or so boxes of stuff and shed things as we went. The house is back but a lot of “stuff” didn’t make!
Huge nuisance...but with a silver lining. I don’t suggest this method.
During our remodeling(s) over the past year, 100% of that stuff was put out with the garbage.
We also had the water heater leak last year, what a mess!
