I prepared samples of our cement siding for asbestos testing today, in anticipation of RIPPING it off. While I was at it, I scraped off a bit of the popcorn ceiling to send off, too, as the cost is $30 for one or $20 each. I figured I can get the ceiling tested for $10.
I am using Western Analytical Laboratory for the testing for a few reasons. Number one is that it is confidential; only I (and anyone I authorize) can see the results. The other reason is that One Project Closer posted a good review of their experience with WAL. It's always good to go with something tried and true!
Here's hoping that NEITHER the siding or the popcorn has asbestos in it! (Although, I would settle for the popcorn not having any).
