More times than not the asbestos tests come back with the drywall mud and/or texture containing asbestos. With early 60’s drywall asbestos could be a problem also. It doesn’t cost much for a test to know what you’re dealing with. Contact Arizona Environmental Specialists at 480-553-7052 to have a qualified inspector discuss your concerns. Abatement costs could be cheap compared to a liability lawsuit or OSHA/EPA fines & intervention.
