Air
Quality and Mold Sampling Level I Assessment - Air Quality Testing A
Level I Assessment is conducted to rule out potential sources of mold
contamination when no suspected mold colony has been identified. The Level I
Assessment requires the collection of air samples from at least two
locations: one indoors and one at least ten feet outside the exterior
of the home. Additional samples may be required where conditions
are deemed to be conducive to moisture and/or mold colonization. Level II Assessment - Air Quality and
Mold Testing A
Level II Assessment includes all the components of a Level I Assessment plus the evaluation
and characterization of suspected mold colonization on a surface. It is used to
determine whether a stain, discoloration, blemish, raised material or other
irregular appearance on a surface is, in fact, mold. A minimum of two physical
surface samples must be collected and tested: one from the suspect area and
another from a non-suspect surface that is similar in material and physical
characteristics but is free of stain, discoloration, blemish, mold-like
substance or irregular appearance and appears to be free of active or dormant
mold growth. Allergen and Particulate Screening Testing
for pollens, animal dander, dust mites, cockroach particles and other
particulates that may aggravate allergies, asthma or other sickness is done
through surface sampling throughout the residence. The aggregate
sample is then sent to the lab for analysis for testing and reporting. Certified Laboratory Testing McKinney
Home Inspection utilizes PRO-LAB Laboratories, to provide independent
and unbiased certified laboratory testing of the samples which we collect.
