Find Hidden Mold and Its Moisture Source

Hidden mold can damage your home and affect indoor air quality. Also, testing tells you whether mold levels are elevated, and a moisture investigation helps pinpoint why. In addition, you can add radon testing to any inspection.

Quick Answer

Mold and air quality testing uses air and surface samples, analyzed by an independent laboratory, to determine whether elevated mold is present in a home. Lee’s Home Inspections combines sampling with a moisture investigation to help homeowners and buyers in Louisville and nine surrounding Kentucky counties find the source of the problem, not just the symptom.

Why Mold Testing Matters

Mold needs only moisture and something to grow on, and many building materials qualify. Hidden growth behind walls, under floors, in attics and crawlspaces can go unnoticed for months while it damages materials and affects indoor air quality. Plus, some people are sensitive to mold and may experience allergy-like symptoms. Testing gives you facts instead of guesswork. Mold testing is especially helpful after a roof leak, plumbing failure or flooded basement.

Moisture Is the Real Problem

In the Louisville region, humid summers, heavy spring rains and homes with basements and crawlspaces create plenty of opportunities for moisture problems. Common sources include:

  • Basement or crawlspace water intrusion and high humidity
  • Roof, flashing and plumbing leaks
  • Poor attic ventilation and bathroom exhaust fans that vent into the attic
  • Condensation on HVAC ductwork and equipment
  • Gutters and grading that direct water toward the foundation

Mold will return if the moisture source is not corrected, so identifying the cause is just as important as identifying the mold.

How Mold Testing Works

  • Visual and moisture inspection: Lee looks for visible growth, staining, odors and elevated moisture using a moisture meter.
  • Indoor air samples: air is drawn through a sampling cassette in areas of concern to capture airborne spores.
  • Outdoor baseline sample: an outdoor sample provides a comparison for normal spore levels.
  • Surface samples: when suspect growth is visible, a surface sample identifies what it is.
  • Laboratory analysis: samples are analyzed by an independent laboratory.

Understanding Your Mold Testing Results

There are no federal limits for indoor mold. Instead, the lab interprets results by comparing indoor spore counts with the outdoor baseline and by noting types of mold associated with water damage. Your report explains the results in plain English and recommends next steps, which may include correcting a moisture source or consulting a qualified remediation contractor.
