"We were getting our house ready to put on the market when we found mold in the crawl space and one of the closets. MacCraft came out the same day we called— Alex walked us through exactly what needed to happen, gave us an estimate, and got it handled. They documented everything so we had paperwork to show buyers. House passed inspection without any issues. Highly recommend them"

Mold Testing and Remediation FAQs, answered by experts

Yes, if there is mold in your drywall mud and you then use it to build walls in your house—or if mold develops in your set drywall, like it can in hot and humid areas—it can lead to illness. Mold in your drywall (or other parts of your home) can make existing respiratory conditions or allergies worse, and the effect can be more intense for those who have existing health issues or compromised immune systems.

Not all molds are inherently harmful, but their presence can lead to health issues, especially for individuals with allergies or respiratory problems. Black mold often garners attention due to its potential toxicity. However, other molds can cause health concerns too. Regular mold, appearing in various colors like green, gray, brown, or black, can trigger allergies and respiratory problems. Prompt removal and prevention measures are essential, regardless of mold type, to maintain a healthy indoor environment.

The CDC does not consider diatomaceous earth toxic to humans or animals, though it can cause skin, eye, and lung irritation when handled without PPE. It's important to note that non-food-grade diatomaceous earth can be toxic when handled or consumed, so homeowners should only purchase the food-grade option.

Wood stain is not considered toxic after it dries. The solvents in wood stain are what give off volatile organic compounds (VOCs), which are toxic, but these dissolve as the product dries, leaving behind a non-toxic product. When working with wood stain, you should always wear a respirator and rubber gloves to protect yourself, but once it dries fully, it’s not toxic, according to the manufacturer’s instructions.

Water damage doesn’t always cause mold and wood rot, but it can. Both mold and wood rot require moisture in the wood to form, so water damage that continues to leave water or moisture behind can lead to both issues. Water damage and mold often go hand-in-hand, but you can prevent mold growth after water damage by addressing the source of moisture and drying out the area quickly. The same goes for wood rot. The longer you let water damage go, the higher the risk of mold and rot.
