Mold Questions from Durham Homeowners, Landlords and Renters

Look for a musty smell, dark or white fuzzy spots, water stains, bubbling paint or soft drywall. In Durham homes, common places are crawl space joists, attic roof decking, around ceiling vents, bathroom ceilings near the fan, and under sinks. If you can see it, you usually don't need a test to confirm it is mold.

The CDC says that for some people, mold can cause a stuffy nose, sore throat, coughing or wheezing, burning eyes, or skin rash, and that people with asthma or mold allergies may have severe reactions. If anyone in the home has symptoms, talk to a doctor. This site does not give medical advice.

Color doesn't tell you much, and the cleanup is the same: fix the water and remove the growth carefully. The CDC says you do not need to know the type of mold, and that no matter what type is present, you need to remove it. A large dark patch is treated like any other large mold problem.

Quickly. Stop the water if you safely can, then start drying with fans and a dehumidifier. EPA advises drying water-damaged areas and items within 24 to 48 hours to prevent mold growth. Photograph everything before anything is thrown out, and call your insurer.

No state mold license was found in a scan of the NC statutes, so checking credentials is up to you. Look up IICRC and ACAC certifications in their public locators, ask for an insurance certificate, and check the NC general contractor license for rebuild work of $40,000 or more (G.S. 87-1). Never assume a company is licensed for mold.

North Carolina law doesn't stop it, but state health guidance advises: "Do not hire a consultant who also provides remediation services" (NCDHHS, 2005). Using an independent assessor for the first look and for clearance is best practice, so the person checking the job doesn't profit from the work.

Not as a rule. Under 11 NCAC 08 .1105, NC home inspectors are not required to determine the presence or absence of mold. They do enter crawl spaces and report signs of abnormal water penetration or condensation. A home inspection isn't a mold inspection, so ask whether a mold check is a separate add-on.

Sometimes, in older homes. Tear-out can disturb asbestos in old flooring, drywall compound or pipe insulation. Ask whether an accredited asbestos inspection is needed before work starts. Abatement above 35 cubic feet, 160 square feet or 260 linear feet needs a state permit. The NC Health Hazards Control Unit answers questions at 919-707-5950.

Usually not for the cleanup itself. Under G.S. 160D-1110(c), single-family work of $40,000 or less needs no building permit unless it involves structural, plumbing, HVAC or electrical work. Rebuilds can cross that line. For Durham-specific rules, check with Durham City-County Inspections.

White growth on joists or subfloor usually means the wood is staying damp. In humid Triangle summers, vented crawl spaces can hold very moist air; an Advanced Energy field study in Princeville, NC found wall-vented crawl spaces often above 80 percent relative humidity in summer. See crawl space mold.

Not by itself. Encapsulation is moisture control: a sealed liner, closed vents and often a dehumidifier. It can help keep mold from returning, but existing growth still needs to be cleaned. This Old House (Mar 2026) puts encapsulation at about $5,500 on average. Ask for remediation and encapsulation as separate prices.

NC law doesn't use a mold standard, but G.S. 42-42 requires landlords to keep rentals fit and habitable, and it lists "standing water, sewage, or flooding problems caused by plumbing leaks or inadequate drainage that contribute to mosquito infestation or mold" as an imminently dangerous condition. Put requests in writing. Not legal advice. See rental mold.

Not on your own. G.S. 42-44(c) says a tenant may not unilaterally withhold rent before a court decides there is a right to do so. Send a dated, written repair request with photos and keep a copy. Durham has its own housing code process; check with the City for current rules. Not legal advice.
