Certified Mold Testing

Results you can trust

Mold testing helps determine if mold is present, what type it is, and how serious the problem may be. At ZeroMold, our professional mold testing services provide reliable data about indoor air quality and potential mold contamination—so you can take the right next step with confidence.

We use targeted air and surface sampling, combined with professional analysis, to identify mold spores that may not be visible to the eye. Whether you’re experiencing health symptoms, musty odors, or recent water damage, our testing process delivers clear answers without guesswork or scare tactics.

When Mold Testing Is (and Isn’t) Needed

Honest Guidance Based on Your Situation

Mold testing is not always required—and a trustworthy professional will tell you that. At ZeroMold, we recommend mold testing when it provides meaningful information that helps guide next steps, not simply to generate a report.

  • Mold is suspected but not visible

  • You’re experiencing health symptoms

  • There has been recent water damage or flooding

  • You need documentation for real estate transactions or insurance

  • You want to verify indoor air quality concerns

In cases where visible mold is already present, testing may not be necessary to begin remediation. In those situations, addressing the source and correcting the problem is often the priority.

Types of Mold Testing We Offer

Air Sampling

Air testing measures the type and concentration of mold spores in the indoor air. This is especially useful when mold is suspected but not visible, or when evaluating indoor air quality concerns related to health symptoms.

Surface Sampling

Surface testing is used to identify mold growth on visible surfaces. This helps confirm the presence and type of mold in specific areas and can be useful for documentation or further evaluation.

Targeted Testing Only—Never Excessive

We only recommend testing that provides meaningful insight. If testing isn’t necessary, we’ll tell you. Our goal is to give you clear answers, not overwhelm you with unnecessary samples or reports.

Mold Testing FAQs

Clear Answers About Professional Mold Testing

Do I always need mold testing if I suspect mold?

No. Mold testing is not always necessary. If visible mold is present, remediation can often begin without testing. At ZeroMold, we only recommend testing when it provides useful information that helps guide next steps.

What does mold testing actually tell me?

Mold testing can identify the presence, type, and concentration of mold spores in the air or on surfaces. This information helps assess indoor air quality and determine whether further action is needed.

Can mold testing tell me if mold is dangerous?

Testing can identify mold types and spore levels, but it does not diagnose health conditions. Results are best used as part of a bigger picture that includes symptoms, moisture conditions, and professional evaluation.

How long does it take to get mold testing results?

Results are typically available within a few days after samples are analyzed. Once received, we review the findings with you and explain what they mean in clear, easy-to-understand terms.

Will ZeroMold explain the results and next steps?

Absolutely. We walk you through the results and provide honest recommendations. If remediation is needed, we explain why. If it’s not, we’ll tell you that too—no pressure, no scare tactics.
