Wonder if he ever compared the cost of labor for cutting it up to just tossing it? Dumping old drywall is not cheap anymore, around here, anyway.If we can't prove a date more recent than 1992, it is treated as Asbestos. It needs to be cut into small squares to fit into $4 double plastic bags, taped, goose necked and taped again. Then a time must be arranged for when the landfill can accept those sacks, which are weighed and billed by weight. I recently disposed of 4 9 foot sections of old drywall, cost about $40 for 6 sacks.
