Top 5 Signs You Need a Mold Inspection
When mold grows behind walls, beneath flooring, or inside HVAC systems, it silently affects your health and home value.
At Mr. Mold Inspector, we perform thousands of certified mold inspections and lab tests every year across Chicago, Evanston, Naperville, and surrounding suburbs.
Here are the top five signs it’s time to schedule a professional inspection before the problem spreads.
1️⃣ You Smell a Musty Odor
That “old basement” smell is usually microbial growth feeding on damp drywall or framing.
If you can smell mold but can’t see it, it’s often hidden behind paint or paneling.
A certified inspection with air sampling and thermal imaging confirms the source and species.
2️⃣ You’ve Had Water Leaks or Flooding
Even small plumbing leaks leave behind trapped moisture that supports mold within 24–48 hours.
If your home recently experienced sump-pump overflow, roof leaks, or storm flooding, call for a post-dry-out inspection to prevent hidden colonies.
3️⃣ You See Discoloration or Stains
Dark spots, bubbling paint, or fuzzy patches along walls and ceilings indicate moisture behind surfaces.
Different molds show up in different colors — black, gray, green, or white.
Our inspectors collect surface swabs and send them to an AIHA-accredited lab for verified identification.
4️⃣ Family Members Have Allergy-Like Symptoms
Coughing, congestion, or fatigue that worsens indoors often points to elevated airborne mold spores.
Air samples taken during an inspection reveal what’s circulating through your vents and whether it exceeds outdoor control levels.
5️⃣ You’re Buying or Selling a Home
Real-estate inspections rarely include mold testing.
A dedicated mold inspection protects buyers from hidden contamination and gives sellers documentation showing the property is clean and dry.
Bonus Sign: Mold Keeps Coming Back After Cleaning
If you’ve scrubbed visible growth only to see it return, you’re dealing with a moisture source, not just a surface problem.
Our thermal imaging and moisture testing pinpoint the true cause so remediation actually lasts.
