Today's show talks about how home inspectors go beyond the call of duty and help homeowners more than expected.

Reuben explains wood foundations and moisture testing, polybutylene plumbing  and leaking. Tessa talks about health and safety issues such as drafting at combustion appliances, microbial growth in houses and elevated levels of moisture. Bill shares his experience with carbon monoxide during inspections. They also discuss aluminum wiring  as the worst and most expensive electrical problem that they may encounter during an inspection.

Bill asks about the quality of asphalt and organic shingles, and vermiculite insulation in attics. Reuben mentions that asbestos in this insulation causes health hazards. They also talk about balloon framing and molds in the attic.
