How to find hidden mold in your home
How to understand a mold inspection report, and the sample results
How to use the inspection report to tell if your home is mold-contaminated - and - if occupant exposures are acceptable


Dr. Spurgeon has performed thousands of mold inspections on both residential and commercial properties. As a result of those inspections, it became obvious that the typical consumer did not have the knowledge necessary to participate in the inspection process. This book attempts to help consumers whose homes have been affected by water damage to become informed consumers of a mold inspection.

There are two objectives of a mold inspection. The first is to determine if the home is contaminated with mold; and the second is to determine if occupant exposures are acceptable. Unfortunately, having your home inspected for mold can be like buying a used car. The salesman knows the condition of the car, but there is little guidance available to the consumer.

When having your home inspected, the mold inspector may understand what’s happening, but the consumer is rarely an informed consumer; and often does not understand either the inspection process or how to interpret the sample results. The topics discussed in this book include:

  • How do I know if my home may have mold?
  • Do men and women respond to mold differently?
  • Mold and immune-compromised occupants
  • How to find hidden mold in your home
  • Your options for responding if your home does have mold
  • Understanding the parts of a mold inspection
  • What types, and where, should mold samples be collected
  • Options and costs for analyzing mold samples
  • Understanding the sample results in a mold report
  • How much mold in your home is too much?

Besides conducting thousands of mold inspections, Dr. Spurgeon has presented numerous courses teaching inspectors how to perform mold inspections, collect samples, and to interpret sample results.

Dr. Spurgeon has also served as an expert witness in hundreds of mold cases.
