Return on investment is $300? How do you figure its $300? You need a temp and humidity meter. You need a mold machine, a calibration device, education, and the time to understand what you are doing. Then once you get the results you have to be able to explain them. Then there is additional insurance. Then you have to get a back up of all equipment, how can you offer something and the minute it breaks you are screwed?
Copies of IICRC S520. IICRC S500, IICRC S300…those books alone are about $300.
Its so damn funny that people think mold “inspections” are taking a sample sending it to a lab and then being “off the hook”. Why is it acceptable to do this and yet if a guy bought $300 worth of tools and had ZERO home inspection knowledge and sold himself out as a home inspector you would crucify him.
Learn to do whatever you want to do and be the best you can be, all other services still reflect on your company image. Those who think mold testing takes 20 minutes and zero liability and education is not only ripping the client off, they are also doing a disservice to their own company…
