Here to talk briefly on moisture intrusion investigation. When you have moisture in your home, typically there is going to be a mold concern.
Any moisture that stays in the sub straight of the building materials for 72 hours or more is considered dwell time. After 3 days, we no longer look at it as a water damage job, we look at it as a suspect mold job.
To deal with moisture, you need to deal with an electronic moisture meter to help determine what the dry state is or what a dry standard is an area of your home or building that’s not damaged, then compare it to areas of concern.
If the moisture meter is reading 20% +, you’re most likely going to have mold growth. We would want to get that down to 16% or less so there would be no chance of mold growth.
How you can check for moisture without using a hand held moisture reader which is only really good for the walls and floors unless they are concrete. You need a special meter for concrete.
