Biohazard Remediation FAQs, answered by experts

In some cases, black stains on brick are caused by organic substances like algae and mold. However, it's more likely that the black spots you're noticing on your bricks come from carbon from vehicle exhaust or soot. Black stains can usually be removed by scrubbing the brick with a brush and masonry cleaner or power washing.

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.

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.

Several household cleaning products will permanently kill mold, most notably vinegar and hydrogen peroxide. Bleach can also kill mold, but usually just on the surface. Any mold lingering underneath will survive. 

For moldy areas larger than 10 square feet, you'll want to hire a professional mold remediation company to determine the best way to permanently remove the mold. A local mold inspector can help you determine the extent of a mold problem, and what steps you need to take to eradicate it.

While pressure washing can remove debris from a fence, power washing is usually more effective since it uses hot water (rather than warm or cold water). In some cases, additional cleaning methods are also needed to target mold. Fence cleaning professionals can often provide eco-friendly, pet-safe cleaning solutions for removing mold from fences.
