Certified Mold Testing & Inspection Services
When you suspect mold in your Wilmington home or business, the first step isn’t removal — it’s accurate testing. Without proper inspection, mold problems often go unseen and untreated until they’ve spread into walls, basements, or HVAC systems. At MSI, we’ve been providing professional mold testing in Delaware, Pennsylvania, and New Jersey since 1998, trusted by homeowners, realtors, and even the courts for reliable results.
Why Mold Testing Matters in Wilmington
Wilmington’s mix of historic rowhomes, aging apartment buildings, and modern riverfront condos creates plenty of opportunity for hidden mold growth. Heavy summer humidity, rainstorms, and plumbing leaks often cause problems that aren’t visible on the surface.
Mold testing helps:
-
Confirm whether suspicious spots are actually mold
-
Identify hidden contamination in walls, ceilings, or HVAC ducts
-
Determine the type of mold and potential health concerns
-
Provide documentation for insurance or real estate transactions
-
Define the scope of remediation if removal is required
Our Mold Testing Methods
MSI uses industry-standard testing and inspection techniques to give you clear answers:
✔ Air Sampling – Measures airborne spores and compares them to outdoor levels
✔ Surface Sampling – Swab or tape samples taken from visible growth areas
✔ Inner-Wall Cavity Testing – Checking behind walls where mold may hide after leaks
✔ Moisture Mapping & Thermal Imaging – Identifying water damage before mold spreads
✔ Clearance Testing – Verification that mold remediation was successful
