If you are dealing with mold in a Mississippi home or business, you want a qualified remediation company that can find the moisture source, contain the problem, and remove the mold safely. Below you will find a directory of independent mold remediation companies serving communities across the state. We are Mold Inspection & Testing (MI&T), and to help you hire with confidence, we have gathered plain-English facts about how mold remediation works in Mississippi, what the state does and does not regulate, and why our warm, humid, storm-prone climate makes mold such a persistent challenge here.
Choose your city or region below to see independent mold remediation companies serving your area of Mississippi.
Before you hire a remediation company, we strongly recommend starting with an independent mold inspection and test. Getting objective, third-party results first means the scope of work is defined by the evidence, not by the company you are paying to do the removal.
A quick but important note: MI&T performs mold inspection and testing only. We do not perform mold remediation, and we do not sell removal services. That separation is deliberate. Because we never bid on the cleanup, our inspection findings and laboratory results stay independent. We offer this page and the directory below as a free courtesy so Mississippi homeowners, renters, and property managers can make informed decisions. The remediation companies listed here are independent businesses that we do not own, control, or warrant.
Mississippi has one of the most humid climates in the United States, and moisture is the single thing indoor mold needs most. According to the NOAA Mississippi State Climate Summary, the state averages about 55.9 inches of precipitation a year, ranging from roughly 50 inches in the north to about 65 inches along the Gulf Coast. The five-year stretch from 2016 to 2020 was the wettest on record, averaging 63.1 inches annually. Warm, water-laden air pushing in from the Gulf of Mexico keeps humidity high nearly year-round, and heavy 3-inch-plus downpours have trended above average since 1970.
Storms add sudden, catastrophic moisture on top of the everyday humidity. Hurricane Katrina in 2005 devastated the Mississippi coast, causing 238 fatalities in the state and driving a storm surge that reached 27.8 feet at Pass Christian. Inland, the 2011 Mississippi River flood caused more than $500 million in agricultural damage in Mississippi alone. Whether the water arrives as a hurricane surge along the coast, a swollen river through the Delta, or a flash flood in Jackson, saturated drywall, framing, and flooring can begin growing mold within a day or two if they are not dried quickly and correctly.
Everyday building conditions finish the picture. Mississippi's long, hot air-conditioning season pulls humid air across cool surfaces and ductwork, where condensation collects. Crawl-space and slab-on-grade homes are common, and both can trap ground moisture against floors and walls. Combine year-round humidity, frequent flooding, and warm temperatures, and it is easy to see why so many Mississippi households eventually confront mold.
Here is the key point many homeowners are surprised to learn: Mississippi does not license or certify mold remediators or mold assessors. There is no state-issued mold credential, no mandatory state exam, and no state agency that inspects mold work. When larger repair or reconstruction is involved, a job may fall under the general contractor licensing rules of the Mississippi State Board of Contractors, and local building permits can apply, but none of that is mold-specific.
Because the state sets no baseline, the burden of vetting falls on you. We suggest treating voluntary industry credentials as your yardstick: ask whether technicians hold IICRC certification, confirm the company carries general liability insurance (and, ideally, pollution coverage), and ask for recent references. An independent inspection and test adds another layer of protection, giving you documented conditions that do not depend on any single company's word.
Rental situations follow the Mississippi Residential Landlord and Tenant Act, found at Miss. Code Ann. Title 89, Chapter 8. Under Section 89-8-23, a landlord must comply with applicable building and housing codes materially affecting health and safety and keep the dwelling in substantially the same condition as at the start of the lease, aside from normal wear and tear. Mississippi has no mold-specific statute or mold disclosure requirement, so mold issues are generally handled through these broader habitability duties.
A distinctive Mississippi detail is how limited tenant remedies are. State law does not give residential tenants a broad repair-and-deduct right. Instead, a tenant who believes the landlord has materially failed to maintain the premises must provide written notice identifying the problem, and may terminate the lease if the landlord does not cure it within the statutory timeframe. Because the procedure is strict, careful documentation matters. An independent mold inspection and test creates a dated, third-party record of conditions that can support a written notice. This is general information about Mississippi law, not legal advice; for guidance on your situation, consult a qualified Mississippi attorney.
Since Mississippi imposes no state license, the best remediation companies hold themselves to recognized voluntary standards. The most widely used is the ANSI/IICRC S520 Standard for Professional Mold Remediation, which covers containment, worker protection, moisture control, and verification that the job is actually finished. Reputable companies also follow the U.S. Environmental Protection Agency's mold remediation guidance, and they send air and surface samples to laboratories accredited through programs recognized by the American Industrial Hygiene Association (AIHA). Ask any company you are considering how it applies these standards on your project, and how it will verify results when the work is done.
Before removal begins, get an objective assessment of what you are dealing with. You can schedule an independent MI&T inspection at https://moldinspectionandtest.com/mississippi. Independent testing keeps the scope honest and gives you a documented baseline.
Because there is no state mold license to check, confirm IICRC certification, current liability and pollution insurance, and references from recent Mississippi jobs. Ask whether the crew follows the S520 standard.
A trustworthy remediator provides a detailed written scope, explains how it will control moisture at the source, and agrees to a post-remediation clearance test, ideally performed by an independent party, before it calls the job complete.
The lowest bid is not always the safest choice. Weigh the scope of work, the standards followed, and the verification plan together, so you are comparing genuinely comparable proposals.
Use the directory below this article to find independent mold remediation companies serving Mississippi communities, from the Gulf Coast and Hattiesburg to Jackson, the Delta, and Tupelo. We suggest starting with an independent mold inspection and test so you have documented, third-party results before you hire anyone to do the work.
Mississippi does not issue a state-specific license or certification for mold remediation or mold assessment. Larger repair or reconstruction work can fall under the Mississippi State Board of Contractors' general contractor licensing rules, and local permits may apply. Because no mold license exists, we recommend confirming a company's voluntary certification, insurance, and references instead.
Mississippi is one of the most humid states in the country, averaging about 55.9 inches of rain a year statewide and up to roughly 65 inches along the Gulf Coast. Warm, moisture-laden air from the Gulf of Mexico, a long air-conditioning season, hurricanes and tropical storms, and repeated river and coastal flooding all give indoor mold the moisture it needs to grow.
Mississippi's Residential Landlord and Tenant Act (Miss. Code Ann. Title 89, Chapter 8) requires landlords to comply with applicable building and housing codes materially affecting health and safety and to keep the unit in substantially its original condition. There is no mold-specific statute. Tenant remedies are limited: there is no broad repair-and-deduct right, but a tenant who gives proper written notice may terminate the lease if the landlord fails to cure. This is general information, not legal advice.
Look for companies that follow the ANSI/IICRC S520 Standard for Professional Mold Remediation and EPA mold guidance, and that use accredited laboratories, such as those recognized under AIHA laboratory accreditation programs, for sampling and analysis. These voluntary standards matter especially in Mississippi, where no state mold license sets a baseline.
Both can help. An independent inspection and test before work documents the type and extent of the problem and defines the scope, and a post-remediation clearance test confirms the work succeeded. Because we only inspect and test and never perform remediation, our results stay independent of whoever does the removal.
