Mold after water damage!!
We received a call last week from a customer who was noticing some discoloration in his wall. He wasn't sure if it was water damage and requested an inspection. He wanted SERVPRO to come out before they got mold.
Primarily we use non-intrusive moisture meters to detect water damage. The advantage of this type of moisture meter is that it does not physically damage the materials that it is testing. This is compared to some moisture meters that use metal probes that pierce the object being tested.
Our inspection revealed that not only was his wall cavity affected, but a fair sized amount of flooring. Look in the photo how we found another layer of tile below the floating floor. Customers are often surprised to find one, two, or sometimes even three old floors under a laminate floor.
