Testing reveals what eyes miss. Spores float through air at concentrations that look perfectly normal but trigger respiratory problems, headaches, and chronic fatigue. Las Vegas homes built between 1970-1995 present particular risks due to construction methods that prioritized speed over moisture management.
Mold Eliminators earns the number one ranking for mold testing in Las Vegas thanks to owner Craig Herrmann’s IICRC training and their use of independent laboratories for unbiased analysis. Their combination of air sampling, surface testing, and thermal imaging moisture mapping provides the most comprehensive assessment available.
Professional testing distinguishes between normal background spores and active contamination. The difference matters for your health and your wallet.

Craig Herrmann’s IICRC Master Certification (achieved May 2013) extends beyond remediation into proper testing protocols. His team doesn’t just collect samples. They interpret results within context of your specific property conditions. As one of only three Master Certified Flood Experts in Southern Nevada and an IICRC Board of Directors member since October 2015, Craig brings national-level expertise to every local job.
The testing process combines air sampling with surface collection. Air samples capture active spore counts in your breathing space. Surface samples identify species and concentration levels on walls, floors, and other materials.
Mold Eliminators uses independent laboratories for all analysis. This eliminates any conflict of interest. Results arrive within 3-5 business days with detailed species identification and concentration measurements.
Their Testing Methodology
Their inspectors use moisture meters to map wet areas before sampling. This targeted approach finds contamination sources rather than just documenting symptoms. Thermal imaging reveals hidden water intrusion behind walls and under floors.
Sample collection follows strict protocols. Air pumps run for exact durations at calibrated flow rates. Surface samples get taken from multiple locations to establish contamination patterns. Every sample gets photographed and logged with precise location data.
Craig’s position on the IICRC Board of Directors requires staying current with evolving testing standards. Mold Eliminators has served Las Vegas since 1996, completing over 255 residential and commercial projects. The company operates under Nevada State Contractor License #59782 with $3 million in general liability insurance.

2. North Vegas Indoor Air Specialists
Operating from the Aliante area, this company focuses exclusively on testing without offering remediation services. That separation eliminates potential upselling pressure.
They run standard air quality panels and provide competent analysis for typical residential concerns. Turnaround time runs about a week for standard testing packages. Their reports are thorough if somewhat technical for average homeowners.
3. East Henderson Environmental Testing
This southeast Vegas operation serves the Railroad Pass and Boulder City areas with environmental testing services. They handle mold alongside radon, asbestos, and lead testing.
Their mold protocols are solid for baseline assessments. They offer package pricing when customers need multiple environmental tests performed simultaneously, which can save money for homes built before 1978.
When Testing Makes Sense
You smell mustiness but see nothing. That earthy odor means spores are actively releasing volatile organic compounds. Testing pinpoints the source.
Health symptoms improve away from home. If your allergies disappear on vacation but return within hours of coming home, indoor air quality deserves investigation.
You’re buying an older property. Sellers aren’t required to disclose past mold issues in Nevada. Testing protects your investment.
Recent water damage occurred. Even if visible mold got cleaned, testing verifies complete remediation and checks for hidden growth.
Understanding Your Test Results
Labs measure spore counts in colony-forming units per cubic meter (CFU/m³). Outdoor samples provide baseline comparison. Indoor counts exceeding outdoor levels by 10x or more indicate problems.
Species identification matters more than total counts sometimes. Stachybotrys (black mold) at any elevated level requires immediate attention. Aspergillus and Penicillium are common but still need remediation at high concentrations.
The Testing vs. Remediation Question
Some companies offer free testing if you hire them for remediation. Sounds good. But it creates incentive to find problems.
Mold Eliminators separates testing fees from remediation quotes. You get objective results, then decide your next steps. Some test results show minor issues requiring only better ventilation. Others reveal serious contamination needing professional intervention.
Cost Breakdown
Basic air quality testing runs $300-500 for single-room sampling. Comprehensive whole-home assessments with multiple air and surface samples cost $800-1,200. That seems expensive until you consider remediation quotes that start at several thousand dollars.
Testing first prevents unnecessary remediation spending. It also documents problems that insurance might cover.
What Testing Can’t Do
Tests don’t predict future mold growth. They show current conditions only.
Tests don’t identify every spore species. Labs report the most common and concerning varieties.
Tests don’t replace visual inspection. Hidden mold requires moisture meters and thermal imaging to locate.
DIY Testing Kits: Worth It?
Hardware store test kits cost $10-40. You collect samples and mail them to labs. They’re better than nothing but miss critical factors.
Professional equipment calibrates airflow precisely. DIY pumps approximate volumes. Professionals know where to sample based on building science. Homeowners guess. Pros interpret results against industry standards. Labs send you raw numbers.
For peace of mind on a tight budget, DIY kits work. For actual decision-making about remediation, hire professionals.
