Mold grows where moisture sits. St. Louis gives mold exactly what it needs with hot, humid summers, heavy rainfall, and older homes that trap moisture in basements, crawlspaces, and wall cavities.
A professional mold inspection from ORF Home Inspections finds the mold, traces the moisture source, and gives you the information you need to fix the problem.
We inspect homes for mold across St. Louis City, St. Louis County, St. Charles County, Jefferson County, and surrounding communities. Whether you are buying a home, dealing with a musty smell, or concerned about indoor air quality, our mold inspection service delivers clear answers.
Add a mold inspection to your home inspection if you notice musty odors, water stains, or visible mold during your walkthrough. Even homes that look clean on the surface can hide mold behind walls and under floors.
If you smell something musty in your basement, bathroom, or any closed-off room, mold is likely growing somewhere nearby. Visible mold on walls, ceilings, or around windows tells you moisture has already caused a problem.
St. Louis storms dump heavy rain that floods basements and overwhelms drainage systems. Any water event that soaks building materials creates a mold risk within 48 hours.
Recurring headaches, sinus congestion, coughing, sneezing, or worsening allergy symptoms inside your home may point to mold exposure. If symptoms improve when you leave the house and return when you come back, indoor mold could be the cause.
We deliver your mold inspection report within 24 to 48 hours, depending on lab turnaround times for air and surface samples. Every report includes photos of affected areas, moisture readings, lab results with spore counts and species identification, and clear recommendations for next steps. You can share the report with remediation contractors, your real estate agent, or your insurance company right away.

Visible growth on walls or ceilings, musty odors in basements or bathrooms, and water stains on surfaces all point to mold. Health symptoms like sinus congestion, headaches, or worsening allergies that improve when you leave the house also suggest mold exposure. A professional inspection confirms whether mold exists and how far it has spread.
We commonly find Cladosporium on walls and HVAC components, Aspergillus on damp drywall and insulation, and Penicillium on water-damaged materials. Stachybotrys, known as black mold, grows on wet cellulose-based materials like drywall and ceiling tiles. Lab testing identifies the exact species and spore concentration in your home.
You can clean small patches on hard surfaces, but without finding the moisture source, mold comes back. Surface mold often signals a larger hidden problem. The EPA recommends professional assessment for mold covering more than 10 square feet. An inspection tracks down the root cause so the problem actually gets solved.
The on-site inspection takes one to two hours for a typical St. Louis home. We collect air and surface samples and send them to an accredited lab. Lab results come back within two to three business days. You receive the complete report with photos, moisture readings, spore counts, and recommendations within 24 hours of getting the lab data.
