How Much Does Mold Testing Cost in Chicago?

If you’re worried about mold in your home or business, one of your first questions is usually, “How much does mold testing cost?”
In the Chicago area, the price depends on your property type, sample count, and the lab turnaround time — but knowing what you’re paying for makes all the difference.

At Mr. Mold Inspector, we believe in complete transparency. Here’s what Chicago homeowners and property managers should expect when it comes to professional mold inspection pricing.

1️⃣ Average Mold Testing Cost in Chicago

Most professional mold inspections in the Chicago area range from $350 to $450 for a typical single-family home.
At Mr. Mold Inspector, our pricing is simple and transparent:

✅ No hidden fees.
✅ You choose if extra samples are added after inspection.

2️⃣ What Affects Mold Testing Prices

The cost can vary slightly based on:

• Size of the property (larger spaces need more samples)

• Type of materials tested (drywall vs. carpet vs. insulation)

• Access issues (crawlspaces, attics, or high ceilings)

• How many rooms show visible or suspected growth

💡 Pro Tip:
If you only suspect one area (like a bathroom or basement corner), a smaller package is often all you need.

3️⃣ What’s Included in a Certified Mold Inspection

Unlike basic “air tests” you can buy online, a certified inspection includes professional analysis and verified lab reporting.
Here’s what we do during every appointment:

• Full walkthrough and moisture scan of all rooms

• Thermal imaging to detect hidden leaks

• Air and/or surface samples

• Lab analysis by an AIHA-accredited lab

• Complete digital report with recommendations

4️⃣ Why Cheap or DIY Mold Tests Fall Short

At-home mold test kits may look affordable, but they don’t tell you what kind of mold you have or how serious it is.
Without lab calibration or air volume control, the results are meaningless to remediation contractors or insurance companies.

Only certified reports from professional inspectors are accepted for:

• Real estate transactions

• Insurance claims

• Contractor verification

• Legal documentation

5️⃣ Why Chicago Homes Often Need Testing

Chicago’s climate — humid summers, freezing winters, and older brick construction — creates perfect conditions for condensation and hidden moisture.
Basements, attics, and exterior walls often show signs of Aspergillus, Penicillium, or Chaetomium growth long before visible damage occurs.

We’ve tested thousands of Chicago homes and found that nearly 60% of properties with musty odors had elevated airborne mold levels, even without visible growth.

6️⃣ When to Schedule Mold Testing

• After any water damage or flooding

• If you smell musty odors but see no mold

• During real estate transactions

• When family members experience indoor allergy symptoms

• To verify the success of mold remediation

If you’re in Chicago, Oak Lawn, Orland Park, or Romeoville, our licensed inspectors can provide same-week appointments with digital reports delivered within 2–3 days.
