Biohazard Remediation FAQs, answered by experts

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.

Whether it's safe to stay in a house with water damage depends on the severity of the issue. If the damage is minor, such as from a small plumbing or window leak that is caught early and hasn't affected the electrical system or led to mold, it is likely safe to stay. However, for major water damage from flooding or standing water, it is not safe to remain in the home. The primary risks include mold growth, which can begin within one to two days and poses a serious health risk; structural damage that can weaken your home's integrity; and electrical hazards. It is strongly recommended to relocate until a trained professional has inspected the damage, dried the area, treated any mold, and confirmed the home is safe to return to. Your insurance company may be able to help with the cost of alternative housing while repairs are being made.

To kill white mold on wood, a mixture of white vinegar and water (a 1:1 ratio) or a water and hydrogen peroxide combo can be effective. Spray the affected area and let it sit for a few hours before scrubbing the mold off. Borax mixed with water is another option; it not only kills the mold but also prevents future growth. Ensure the wood is completely dry after cleaning, and consider applying a wood sealer or paint to prevent moisture absorption, which discourages mold growth. Regular inspections and maintaining proper ventilation can also help prevent mold recurrence on wood surfaces.

Mold can grow on garage ceiling insulation, which is why it’s important to install a vapor barrier behind the insulation and keep the space cooled and heated as you would your living area. Doing so will more or less eliminate the risk of mold growing on your garage ceiling insulation. You can also install a self-draining dehumidifier to help remove moisture, or opt for a foam board insulation or spray foam insulation that won’t harbor moisture and mold.

Once again, contact with moisture is the culprit here, though water-resistant varieties of wallpaper are less likely to become wet and develop mold. Using a high-quality exhaust fan or dehumidifier and leaving the doors or windows cracked after bathing will keep this issue at bay.
