Does a home inspection impact “closed building conditions?” We’re not leaving windows and doors open, and may run vent fans for a very short period which shouldn’t affect the pressure much. My though is no, but I defer to you, the professionals. Thoughts?
Also, do you typically deploy your devices at the end of your inspection if you’re providing the test?
I deploy mine in advance of the inspection appointment whenever possible, so it ends when I arrive for the inspection. When not possible, I set it at the conclusion of the inspection.
Although MY impact on “closed home conditions” is minimal, my clients are almost always present and even though I coach them at the beginning of the inspection, I don’t babysit them. I always add 12 hours to the test time if clicnts are present to insure timeframe standards are met.
I have been using EMSL exclusively for about 8 years, but due to a drop in the quality of customer service from my rep., I changed to RTCA about 2 years ago. Both labs are NJ/NY based. There is no local lab that is Home Inspector friendly (for Radon) that I have found. Even the County supplied kits are sent out-of-state for analysis.
I should clearify, I still use EMSL local (Minneapolis) for mold, vermiculite, etc testing. Radon is the only test, (or other highly specialized tests), that is sent out-of-state.
