Comprehensive Testing Services

From pre-purchase inspections to post-remediation clearance, we use accredited laboratory analysis to deliver results you can trust.

Air Sampling

Spore trap cassettes capture airborne particles for lab analysis. We compare indoor and outdoor counts to determine if elevated mold levels exist in your property.

Surface Sampling

Tape lift and swab samples identify mold species growing on surfaces. Essential for understanding what type of mold is present and how to treat it effectively.

Moisture Mapping

Infrared cameras and moisture meters pinpoint hidden water intrusion behind walls, under floors, and in ceilings. Moisture is the root cause of mold, so we find it first.

Real Estate Inspections

Pre-purchase and pre-listing mold inspections for buyers, sellers, and agents. Protect your investment with documented testing from a certified professional.

HVAC & Duct Testing

Sampling inside ductwork and HVAC systems where mold commonly hides and circulates spores throughout the building. Critical for properties with persistent musty odors.

Why Testing Matters Before You Remediate

Visible mold tells you there's a problem. Testing tells you how big it is. Air quality testing measures the concentration and type of mold spores in your indoor environment, giving you the data needed to make informed decisions about remediation, health risks, and insurance claims.

All samples are analyzed by an independent, accredited laboratory. You receive a detailed report with spore counts, species identification, and clear recommendations. MoldGone never recommends unnecessary work — if testing shows your levels are normal, we'll tell you.

Air Quality Testing FAQs

Common questions about mold testing, air sampling, and what your results mean.

Do I need air quality testing if I can already see mold?

If mold is clearly visible, testing isn't always necessary to start remediation. However, testing can be valuable for identifying the mold species, documenting the extent of contamination for insurance purposes, and establishing a baseline so post-remediation clearance testing has something to compare against. We'll advise you on the best approach during your consultation.

How much does air quality testing cost?

Testing costs vary depending on the number of samples needed and the size of the property. A standard residential air quality test with 3-4 samples typically ranges from $300-$600 including lab fees. We provide exact pricing before scheduling. Post-remediation clearance testing is often included in the remediation scope of work.

How long does it take to get test results?

Standard lab analysis takes 3-5 business days from when the lab receives the samples. Rush processing is available for an additional fee and can deliver results in 24-48 hours. Once we have the lab report, we contact you to review the findings and discuss next steps.

What's the difference between air sampling and surface sampling?

Air sampling captures spores floating in the air you breathe. It tells you whether mold levels are elevated compared to outside air. Surface sampling (tape lift or swab) identifies what's growing on a specific material. We often use both together: air samples show the overall indoor air quality, while surface samples confirm the species and guide the remediation approach.

Can I buy a home test kit instead?

Over-the-counter mold test kits are unreliable for several reasons: they use passive settling plates that don't measure actual spore concentration, they lack outdoor control samples for comparison, and they don't follow standardized collection protocols. Professional testing uses calibrated air pumps, accredited labs, and established methodology that insurance companies and health professionals recognize.

What does a 'normal' mold level look like in test results?

There's no single number that defines 'safe.' We compare indoor spore counts to outdoor counts. In a healthy building, indoor levels should be similar to or lower than outdoor levels, and the species should be comparable. Elevated indoor counts or the presence of certain species like Stachybotrys (black mold) or Chaetomium indicate a problem. We explain exactly what your results mean in plain language.

Do I need testing before buying a home?

We strongly recommend it, especially for older homes, properties with basements or crawl spaces, and any home with visible water staining or musty odors. A pre-purchase mold inspection can uncover hidden problems that a standard home inspection might miss. The cost of testing is minimal compared to discovering a mold problem after closing. We provide results fast enough to meet most inspection contingency deadlines.

D. Smith

He easily could have recommended a full (and expensive) remediation project of our entire kitchen flooring, but gave us an honest answer that likely saved us thousands of dollars at this time - while being realistic we may need to do so in the future.
