Biohazard Remediation FAQs, answered by experts

If contractors discover water damage, rot, or mold beneath the stucco, additional repairs will be necessary. These repairs can increase your total project cost and timeline, but addressing them promptly is essential for your home’s structural integrity. Ignoring hidden damage can lead to more severe issues and higher costs in the future.

Signs you may need mold remediation include visible mold growth on walls or ceilings, a persistent musty odor, or health symptoms like allergies and respiratory issues. Areas affected by water damage or excessive humidity are prone to hidden mold. A professional inspection can confirm whether mold remediation is required, especially for large or concealed infestations.

When you smell something, it’s because the particles of what you are smelling are floating through the air. If you smell mold, it means that it’s airborne, and whether or not it’s harmful depends on the type of mold. It’s very hard to tell the difference between molds, even with the internet to guide you. Call a professional as soon as you see mold, they will test it, remove it, and make sure you aren’t breathing anything harmful.

No, it isn’t. This is one of those things that needs to be dealt with immediately because mold will spread at a rapid rate and can go from just one spot on the wall to a serious health risk in a matter of days. Prolonged exposure can be extremely dangerous, so any mold issues (or even suspected mold) need to be dealt with right away. 

To neutralize mildew smell, you can use natural deodorizers like baking soda or activated charcoal. Baking soda absorbs odors; sprinkle it liberally on the affected area, let it sit for a few hours, then vacuum it up. Activated charcoal, available in pouches, works similarly. Vinegar, with its natural acidic properties, can also neutralize odors. Mix equal parts water and vinegar, spray the affected area lightly, then blot it with a dry cloth. Enzymatic cleaners are effective too, breaking down odor-causing compounds.
