"great customer service, shows up on time and they stand by their work. I was worried about a mold smell months after the work was done and they send someone out to look over the house no charge. turns out it was just my dehumidifier, but I would definitely hire them again!"

"I had a very nice experience with the Best Air Quality and Restoration team. The price seemed fair to me. I purchased the duct cleaning, mold treatment services. Amanda was very helpful in scheduling my appointment; I was hoping for an earlier date; Dennis offered to reach out to me if the option presented itself, which it did a few days later. On the date of the appointment, Sergei called to tell me he was on his way. Sergei and his crew of one were professional and attentive to my questions and needs, being mindful of my 6 month old. I was very satisfied with the service, attention and professionalism of Best Air Quality and Restoration. I would recommend and use their services again in the future."

Biohazard Remediation FAQs, answered by experts

The answer depends on the size of your home, the type of mold, and your ventilation systems. However, the best answer would be no, you shouldn’t stay in your home. Arrange to be away from your home during the mold remediation process, as mold is often most dangerous when it’s being removed due to the particles being released into the air. Some contractors won’t proceed with the remediation if you or other household members are in the home.

If you need mold remediation, you’re probably looking at a bill of a couple thousand dollars or more. Sometimes, though, your homeowner’s insurance policy may cover some or all of the costs of the remediation. If the black mold forms because of a covered event, such as a storm that damages your roof, and causes leaking or flooding in the basement, it’s possible the policy also covers mold remediation. It never hurts to ask your insurance company if it will cover the cost of black mold remediation.

No, rubber mulch isn’t toxic and is considered safe to use around pets. However, pets, especially dogs, may try to chew on or eat rubber mulch, which can cause choking. Consider monitoring your pets and their behavior when around this mulch type to see how they respond to it.

There are different types of mold, and not all humans are the same. For example, a more toxic type of mold may have less of an effect on a healthy person than a less toxic mold in the home of someone who is immunocompromised. If you recognize any symptoms of mold poisoning—sinus issues, brain fog, respiratory distress, constraint cough, migraines, or any others—call your doctor or go to the hospital before you attempt any removal.

While bleach can be effective in killing mold, it may not fully remove mold stains from siding. Additionally, bleach can be harsh and may damage certain types of siding. It's recommended to use specialized mold cleaners or natural alternatives that are safe for your specific siding material as a part of your regular siding maintenance.
