What determines the amount of samples to be taken during the inspection?

There are many factors that determine the amount and location of samples taken, as per standard guidelines we are required to collect 1 exterior control sample, 1 interior sample per level and or numbers of AC’s present and one sample in each area that shows visual conditions such as water intrusion and or visual mold growth.

Examples:    
2 story house, 1 Ac per floor: 3 Samples are required
1 story house, 1 AC: 2 Samples are required
1 story house, 2 AC’s on the same floor: 3 Samples are required.

These are minimum requirements and often more samples are recommended. All samples recommended to you by the inspector have a justification on why they need to be collected.
