Mold Remediation FAQ for Charleston Homeowners

Not a mold-specific one. South Carolina's environmental agency says there are no state or federal laws, regulations or standards for mold or indoor air quality, and it cannot test or inspect homes for mold. A bill, H.5109, was introduced in February 2026 to create a state mold board, but it has not passed as of October 2026. This is general information, not legal advice.

South Carolina has no license for mold inspection or removal. Related rebuild work is different: under SC Code §40-59-20, residential specialty contractors such as drywall or insulation installers must register for jobs over $500, and a residential builder license applies above $5,000. Mechanical work over $10,000 needs a license. This is general information, not legal advice.

Ask what mold training or certifications its workers hold, for proof of insurance, and which SC contractor license or registration covers any rebuild work. Ask how it will find and fix the moisture source, what containment it will use, and whether clearance testing is included. The EPA suggests making sure the contractor has experience cleaning up mold.

No. We are a free quote service. We connect Charleston-area homeowners with local mold inspection and remediation companies for free, no-obligation quotes. The company you choose inspects, prices and performs the work and is responsible for it. You are never obligated to hire anyone, and we usually reply to requests the same day.

Often not. The EPA says that in most cases, if visible mold growth is present, sampling is unnecessary. Testing can help when you smell mold but cannot find it, when you want clearance after remediation, or during a home sale. If you test, many homeowners prefer a tester who is independent of the company doing the remediation.

Cost guides put a mold inspection at about $450–$800. HomeAdvisor data cited by Bob Vila shows a wider $299–$1,014 range with an average near $656. Air sample testing typically adds about $250–$350, and advanced testing can reach about $700. Ask what the inspection includes, such as moisture mapping, samples and a written report.

The terms are often used interchangeably. Remediation usually means the whole process: finding the moisture source, containing the area, removing damaged materials, cleaning, drying and confirming the area is clean. Mold removal sometimes refers only to the cleaning and tear-out part. Ask each company to spell out exactly which steps its quote covers.

Quickly. The EPA says water-damaged areas and items should be dried within 24 to 48 hours to prevent mold growth, and South Carolina's environmental agency gives the same window. After a storm, king tide or pipe leak, start drying right away, remove soaked materials if it is safe, and request quotes as soon as possible.

In the City of Charleston, all work on an existing structure in the Special Flood Hazard Area (zones AE and VE), including storm-damage repairs and HVAC ductwork replacement, requires a permit, and permits must be obtained before repairs are completed. Large repairs can trigger substantial-improvement rules. Check with the city or your county. This is general information, not legal advice.

The EPA says a homeowner can usually handle a moldy area smaller than about 10 square feet. After hurricanes, damage is often much larger, materials may be soaked with flood water, and mold may be hidden inside walls. For anything beyond a small area, consider getting quotes. If you have health concerns about mold exposure, talk to your doctor.
