Professional testing of Mold or Lead or Asbestos can range from $300 - $1000 for each type. I just found some home testing kits that require you to take and submit samples.
Are these a good cost savings approach with adequate results or should I consult professionals?
I actually found this on the EPA website. EPA Accredited laboratories. You can just send samples in ziplock baggies to these laboratories for testing. I saw that a lot of the DIY kits out there are essentially just baggies! So no need to buy those kits.
