Biohazard Remediation questions, answered by experts

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.

Yes, mold can grow on nonporous surfaces. Mold is extremely resilient and can survive just about anywhere. However, mold will not grow as quickly on a nonporous surface as on a porous one. Additionally, the nonporous nature makes it easier to remove. Keep the countertop clean and properly maintained, and you shouldn’t experience mold growth.

Humidity, moisture, and a lack of ventilation can all cause mold to grow on surfaces in and around your home.

To remove mold from fabric that’s part of your wood furniture, the best option is to take the fabric off and place it in the washing machine. If you cannot take the fabric off, it helps to move the furniture out into the sun. Use a high-quality vacuum to remove any mold spores that are present. You can try spraying the mold with a 50/50 vinegar-water mixture. Hydrogen peroxide is also a possibility for removing mold from fabric, but it could damage certain types of fabric.

To prevent mold from growing in your washer, use detergent recommended for your specific washer. Afterward, leave the door open after every wash and remove wet clothes as soon as possible. You can also use a mildew cleaner to wipe the gasket and consider using a dehumidifier where you keep your washer. If you think the problem is too big for you to handle on your own, contact a local house cleaner service.
