Looking for a mold remediation or removal company in South Carolina? You are in the right place. Below is our directory of independent mold remediation companies, organized by city so you can find help close to home, whether you are on the Charleston coast, in the Midlands around Columbia, or up in the Greenville and Spartanburg Upstate. The overview that follows explains why mold is so common in South Carolina, what state law does and does not require, which certifications and standards matter, and how to choose a contractor with confidence.
Browse mold remediation and removal companies by South Carolina city below, then reach out to the ones that serve your area.
Not sure where to begin? We suggest starting with an independent mold inspection so any removal work is based on documented findings rather than a sales pitch.
We publish this directory purely as a courtesy to South Carolina homeowners and renters. 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 here is an independent contractor with no affiliation to us, so you can compare your options freely and keep your testing separate from your removal.
South Carolina gives mold almost everything it needs to thrive: warmth, moisture, and time. Summers are long and humid, with July averages reaching about 82°F along the coast and across the Midlands, and much of the state sees roughly 45 to 55 inches of rain a year. The northwestern mountains are wetter still, receiving on the order of 80 inches annually. That steady moisture load, paired with air-conditioning seasons that run for much of the year, means condensation and damp materials are a near-constant risk indoors.
Then come the extremes. Tropical systems are a defining feature of the state's weather: 19 hurricanes made landfall along the South Carolina coast between 1901 and 2020, and heavy inland rain can be just as damaging. During the historic 2015 flood, Columbia recorded 17.7 inches of rain, saturating homes far from the shoreline. On the coast, tidal flooding is intensifying as sea level at Charleston has risen about 1.3 inches per decade, nearly double the global rate, and Charleston logged 14 flood days in a single year in 2020. Water that enters a home during these events often lingers in places owners never see.
Housing stock adds to the challenge. Across the Lowcountry and much of the state, homes are built over vented crawl spaces that pull humid outside air against wood framing, ductwork, and insulation, an ideal setting for mold when moisture is not controlled. Older coastal homes, slab foundations that wick ground moisture, and tightly sealed newer builds each carry their own risks. The common thread is simple: where warm, damp air meets an organic surface for long enough, mold follows.
Here is the key point for anyone hiring in this state: as of August 2026, South Carolina does not license, register, or certify mold assessors or mold remediation contractors at the state level. There is no state mold license to ask for, and no state exam or state-issued credential a company can hold. A bill to change that, H. 5109, would create a South Carolina Mold Assessment and Remediation Board with certification and insurance requirements; it was introduced on February 5, 2026 and referred to the House Committee on Labor, Commerce and Industry, but it remains pending in committee and has not become law. Unless and until it is enacted, the rules described here still apply.
Because there is no government gatekeeper, the responsibility to vet a contractor falls squarely on you. That is not a reason to worry, but it is a reason to be deliberate. Instead of checking a state license number, screen for voluntary industry certification (IICRC or NORMI), current general liability insurance, adherence to recognized remediation standards, and verifiable local references. The sections below walk through exactly what to look for.
South Carolina has no mold-specific landlord statute and no state law requiring landlords or sellers to disclose mold by name. Instead, rental housing is governed by the South Carolina Residential Landlord and Tenant Act, found at S.C. Code Title 27, Chapter 40. Under Section 27-40-440, a landlord must comply with applicable building and housing codes materially affecting health and safety and must make all repairs reasonably necessary to keep the premises in a fit and habitable condition, including maintaining plumbing, heating, ventilating, and air-conditioning systems in reasonably good and safe working order. A serious moisture or mold problem that makes a unit unfit can fall within these duties even though the word "mold" does not appear in the statute.
The Act also sets out how a tenant responds when a landlord does not act. Section 27-40-610 generally requires the tenant to deliver written notice describing the problem; if the landlord does not remedy a material breach within 14 days, the tenant may terminate the lease and may seek actual damages and injunctive relief, plus reasonable attorney's fees where the noncompliance was willful. Because these remedies turn on written notice and documented conditions, an independent mold inspection and test creates a dated, third-party record of what was found and where, which is far more persuasive than a photograph or a verbal complaint. This is general educational information about how the statute reads, not legal advice about your situation.
Without a state license to lean on, recognized standards become your yardstick. The core reference is the ANSI/IICRC S520 Standard for Professional Mold Remediation, which defines how professionals set up containment, control the underlying moisture source, remove contaminated materials, and verify the work is finished. Reputable contractors also follow U.S. EPA mold guidance for cleanup and moisture control in homes. When sampling is part of the job, insist that the analysis be done by an AIHA-accredited laboratory, so the results come from an independent, quality-controlled source rather than the contractor's own bench. A company that can name these standards and explain how it applies them is showing you it does the work correctly.
Since the state issues no mold license, voluntary certification is your best signal of training. Ask whether the firm and its technicians hold current IICRC credentials (for example, Applied Microbial Remediation) or NORMI certification, and ask to see proof. These are individual and company credentials, not a substitute for a state license that does not exist, but they show a genuine commitment to industry practice.
When the same company both tests for mold and sells the removal, it has a direct financial reason to find more work and a conflict when it later certifies its own job as clean. Keeping the two roles separate protects you: an independent inspector defines the problem and verifies the fix, while a remediation contractor does the removal.

Get a detailed, written scope before anyone starts, and make sure it names the moisture source. In South Carolina that source is often a vented crawl space or storm-driven water intrusion, and simply cleaning visible mold without correcting crawl-space humidity or a flood-damaged wall cavity almost guarantees regrowth. A good scope lists the affected areas, the containment and removal methods, how the moisture problem will be fixed, and what post-remediation verification looks like.
Ask for a certificate of current general liability insurance and confirm it is active, since there is no state bond or license standing behind the work. Request references from recent local jobs in similar conditions, a Lowcountry crawl space or a post-storm cleanup, and actually call them.
Collect at least two or three written estimates built from the same inspection findings. Comparing bids side by side helps you spot an inflated scope, an unusually low bid that skips moisture control, and the contractor who explains the work most clearly.

We recommend keeping them separate. When one company both tests and sells the removal, there is a built-in incentive to expand the scope. An independent inspection and test defines the problem, and a separate remediation contractor fixes it, which keeps the clearance testing at the end honest. Mold Inspection & Testing performs inspection and testing only and does not perform remediation.
Look for a company that works to the ANSI/IICRC S520 Standard for Professional Mold Remediation and follows U.S. EPA mold guidance for containment, moisture control, and cleanup. Any sampling should be analyzed by an AIHA-accredited laboratory. Technician-level credentials from IICRC or NORMI show individual training, and current general liability insurance protects you if something goes wrong.
