"Roy and his team were a pleasure to work with. After purchasing a beach house in Kill Devil Hills we discovered that squirrels were living in the attic which seemed like it was going to severely hurt my renovation budget. Roy and his team went above and beyond what other restoration companies would do. They cleaned, disinfected, reinforced the entry point, and replaced the insulation. They even reconnected duct work and additional repairs while they were up there. Not only did they complete the work within budget and scope but the insight, transparency, and assistance were invaluable. Roy treats his customers like long time friends and is happy to do whatever it takes to get the desired result. So thankful I found 7 sounds restoration. 11/10 stars and will definitely hire again for future projects."

"I received high quotes up to $10,000 to remedy my crawlspace from mold. Though each quote did say my crawlspace was not bad and rated it between a 2 and 3 with 10 being bad. So I went with Zero Mold to fog my crawlspace. It was quick, easy and financially affordable. I can now work out a plan to change my insulation and change my vapor barrier as I go instead of laying out a huge chunk of money."

Biohazard Remediation FAQs, answered by experts

Yes, mold can easily grow under your hardwood floors, especially if your house has recently flooded or if there is a leak from a pipe under the floor. Hardwood floors can trap moisture beneath them, creating the perfect environment for mold to grow. Similarly, mold can also grow under your wood floor’s surface paint.

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.

Mold grows in areas with humidity levels above 60%, but ideal conditions for mold growth occur when humidity is between 70% and 90%, especially in poorly ventilated areas. To prevent mold growth, aim to maintain indoor humidity levels between 30% and 50% using dehumidifiers, proper ventilation, and temperature control. Regularly check your home's humidity with a hygrometer to help you monitor and avoid conditions conducive to mold.

Yes, mold in the basement of your home will affect the conditions upstairs. Mold spores can travel through the air and into the supply vents of your home’s ventilation system. It is extremely important to remove any mold in your basement as soon as possible so it doesn’t affect the health of those living in the house.

Bathroom mold tends to reappear due to the persistent presence of moisture and humidity, creating the ideal conditions for its growth. Since bathrooms are inherently humid environments, without proper ventilation, moisture accumulates on surfaces, providing a continuous food source for mold spores. Mold spores are present in the air and settle on damp surfaces to start growing rapidly. Additionally, if the underlying causes of mold, such as plumbing leaks or inadequate sealing, are not addressed, mold will return even after removal. To avoid recurring issues, addressing the root cause by improving ventilation, fixing leaks, and maintaining a dry bathroom environment through regular cleaning and maintenance is essential.
