Every home develops its own water, air, and microbial profile. This category explains how age, construction materials, water chemistry, and usage patterns affect environmental quality. New homeowners can find checklists for initial testing, while owners of older homes can learn about corrosion, sediment, biofilm, and outdated plumbing.

When environmental concerns overlap with water use, a Detekt Home home inspector test provides an immediate check for microbial intrusion.
