Looking for a mold remediation or removal company in Nevada? You are in the right place. Below you will find our directory of independent mold remediation contractors, organized by city so you can quickly reach companies serving your area, from Las Vegas and Henderson to Reno, Sparks, and Carson City. First, this short overview explains why mold shows up even in America’s driest state, how Nevada’s rules (and the gaps in them) affect you, which certifications matter, and how to choose a contractor with confidence.
Use the directory below to browse mold remediation and removal companies by Nevada city and neighborhood.
Not sure how bad the problem is yet? A smart first step is an independent mold inspection, so you know exactly what you are dealing with before you call a remediation company for bids.
We publish this guide purely as a courtesy to Nevada homeowners, renters, and property managers. Mold Inspection & Testing is an inspection-and-testing-only company: we do not perform remediation, and we do not sell mold removal. Every company listed in the directory is an independent contractor, not affiliated with us. Our goal is simply to help you make an informed, unpressured decision.
It surprises many people, but Nevada is officially the driest state in the country, averaging only about 10.2 inches of precipitation per year statewide (1895–2020), according to the NOAA National Centers for Environmental Information. Yet mold does not feed on outdoor rainfall; it feeds on indoor moisture. And Nevada’s extremes actually create plenty of it. The state’s precipitation ranges from as little as 4 inches in the low-elevation southwestern deserts to more than 50 inches on the Sierra Nevada peaks, so the moisture risks in a Las Vegas ranch home look nothing like those in a cabin near Lake Tahoe.
In the Mojave Desert south, where Las Vegas summer highs average around 102°F and regularly top 110°F, the biggest culprits are hidden plumbing leaks, air-conditioning condensation, and evaporative “swamp” coolers, which cool the air by pushing moisture into the home and can leave humidity behind on drywall and in ducts. The North American Monsoon adds sudden summer downpours that frequently lead to disruptive flash flooding across the Las Vegas Valley, sending water into slab foundations and low-lying garages. Farther north around Reno, Sparks, and Carson City, the drivers shift to Sierra snowmelt and river flooding, and events like the 1997 and 2005 Truckee River floods that caused extensive damage in the Reno area.
Nevada’s housing stock adds to the picture. Rapid growth in Clark and Washoe counties produced large numbers of slab-on-grade homes with stucco exteriors, materials that can trap moisture when flashing or grading fails. Combine tight, energy-efficient construction with swamp coolers, monsoon bursts, and the occasional pipe failure, and a home in even the driest state can develop the persistent wet spots where mold takes hold, often out of sight behind walls, under sinks, or around windows.
Here is the key thing to understand: Nevada does not license or certify mold remediation contractors or mold assessors. There is no state-issued “mold license,” and the Nevada Division of Public and Behavioral Health does not regulate the mold trade. Nevada is one of the large majority of U.S. states, roughly three dozen, with no mold-professional licensing at all. In practical terms, that means anyone can advertise mold remediation in Nevada without passing a mold-specific exam or holding a mold credential.
There is one important nuance. When remediation involves construction, demolition, or build-back, work valued at $1,000 or more generally requires a general contractor license from the Nevada State Contractors Board. That license covers construction competency and bonding, but it is not a mold-specific qualification. Because no dedicated mold credential exists, the burden of vetting falls on you. The rest of this guide focuses on exactly what to screen for: voluntary certification, proper insurance, written scopes, and independent verification of the work.
Nevada’s residential landlord-tenant law lives in NRS Chapter 118A. Under NRS 118A.290, a landlord must maintain the dwelling in a habitable condition at all times, which includes weatherproof roofs and exterior walls, plumbing that works, an adequate supply of hot and cold running water, and premises kept clean and sanitary. The statute does not mention mold by name, but serious moisture problems that breach those duties, such as a leaking roof or failed plumbing that leads to mold, can fall squarely within them.
If a habitability problem arises, NRS 118A.355 sets out the tenant’s remedies and the procedure to use them. Generally, a tenant must give the landlord written notice describing the failure and giving the landlord an opportunity, typically 14 days, to make repairs. Depending on the situation, remedies can include terminating the lease, recovering actual damages, or pursuing other relief through the courts, subject to the exact statutory conditions. Tenants cannot rely on these remedies for conditions they caused themselves. None of this is legal advice, and the specifics matter, so documenting the problem carefully is essential. An independent mold inspection with photos, moisture readings, and lab results creates the objective record that both tenants and landlords need if a dispute ends up in front of a court or an attorney.
Because Nevada sets no mandatory standard, the industry’s voluntary standards carry the weight. A capable remediator should work to the ANSI/IICRC S520 Standard for Professional Mold Remediation, the widely recognized benchmark for containment, worker protection, and cleaning. They should also follow U.S. EPA mold guidance for identifying moisture sources, removing porous materials, and cleaning affected areas, and they should send any air or surface samples to a laboratory accredited by the AIHA (American Industrial Hygiene Association). When a contractor can point to these standards, you have a meaningful benchmark to hold them to, even without a state license.
Since Nevada issues no mold license, third-party certification is your best signal of training. Look for technicians certified through the IICRC (for example, the Applied Microbial Remediation Technician credential) or NORMI (the National Organization of Remediators and Mold Inspectors). Ask to see current certificates, not just a logo on a truck.
Whenever possible, do not let the same company both diagnose the problem and profit from removing it. An independent inspection up front and an independent clearance test afterward protect you from unnecessary work and confirm the job actually succeeded.

Get a detailed, written scope before anyone starts. It should name the moisture source, the affected materials, the containment and cleaning methods, and how success will be verified. This matters in Nevada: a contractor who tears out drywall after a monsoon flash flood in the Las Vegas Valley but never diagnoses or corrects the water intrusion, or the swamp cooler adding humidity, is setting you up for the mold to return.
Ask for proof of general liability insurance and, where build-back is involved, a valid Nevada State Contractors Board license and bond. Request references from recent local jobs and actually call them. A reputable Nevada remediator will provide both without hesitation.
Collect at least two or three written estimates. Comparing scopes side by side, not just prices, quickly reveals who understands the moisture problem and who is guessing. Beware any bid that skips the moisture source entirely.
Start with our Nevada directory, which is organized by city so you can jump straight to remediation companies serving your area, whether that is Las Vegas, Henderson, Reno, Sparks, Carson City, or a smaller community. We suggest beginning with an independent mold inspection so you know the extent of the problem before you request remediation bids, then comparing at least two or three licensed, insured, IICRC-certified contractors.
No. Nevada does not have a mold-specific license or certification program for remediation contractors or mold assessors, and the state Division of Public and Behavioral Health does not regulate the trade. However, most build-back and demolition work valued at $1,000 or more still requires a general contractor license from the Nevada State Contractors Board. Because there is no dedicated mold credential, screen carefully for voluntary certification, insurance, and references.
Nevada law does not name mold specifically, but NRS 118A.290 requires landlords to keep a rental in a habitable condition, including a weatherproof roof and exterior walls, working plumbing, and sanitary premises. A serious moisture or mold problem tied to those duties can trigger the tenant remedies in NRS 118A.355, which generally require written notice and a 14-day period for the landlord to fix the issue. This is general information, not legal advice.
Nevada averages only about 10.2 inches of precipitation a year, but mold needs indoor moisture, not outdoor rain. Plumbing leaks, condensation, evaporative swamp coolers that add humidity indoors, summer monsoon flash flooding in the Las Vegas Valley, and Sierra snowmelt near Reno and Lake Tahoe all create the wet building materials that mold needs to grow.
We recommend keeping them separate. When one company both tests and performs the removal, there is a built-in incentive to find more work. An independent inspection and post-remediation clearance test give you an objective baseline and confirmation that the job was done. Mold Inspection & Testing performs inspection and testing only and does not sell remediation, so our findings stay independent.
Look for contractors who work to the ANSI/IICRC S520 Standard for Professional Mold Remediation, follow U.S. EPA mold guidance for containment and cleaning, and send any air or surface samples to an AIHA-accredited laboratory. These voluntary standards matter even more in Nevada because the state has no mandatory mold license to fall back on.
