Are you sure your ceiling contains asbestos?
Not all spray-on, popcorn / acoustical texture ceilings contain asbestos. To know for sure, submit a small sample for laboratory analysis. Cost is minimal. Laboratories are listed in the yellow pages under “Asbestos – Consulting and Testing.” A list of local laboratories may also be obtained by contacting the Division of Air Quality at 801-536-4000.
Use a spray bottle to thoroughly wet three or four small ceiling areas with water mixed with a few drops of liquid detergent. Using a putty knife, take a composite sample by carefully scraping about one square inch of spray-on from each wetted area into a zip-lock plastic bag. If the laboratory results are negative, meaning less than 1 percent asbestos was found in the sample, take two additional samples to confirm the analysis.
If you decide not to check for asbestos, assume the ceiling contains asbestos and treat it accordingly.
Of course, GP&D Restoration performs this test on all their popcorn / asbestos removal projects. Why you ask? Well in the late 90s there was a local company selling drywall compound with asbestos present. They have since left Denver after loosing a class action suit.
Please do not run the risk of exposing your loved ones to such an dangerous carcinogen (agent that can cause cancer).
