"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

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.

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.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

Musty smells often indicate the presence of mold, which can lead to various health risks. Inhalation of mold spores may trigger allergic reactions, causing sneezing, a runny or stuffy nose, and itchy or watery eyes. People who suffer from mold allergies or asthma may experience more severe respiratory problems. Certain types of mold, like black mold, can lead to mycotoxicosis, a condition associated with serious health effects like respiratory problems, fatigue, headaches, and skin irritation if exposure continues for an extended period. Those with weakened immune systems, respiratory problems, or allergies may be more vulnerable to the health risks that come with musty smells. Therefore, it is crucial to address and eliminate the source of the odor promptly.

Many providers offer mold remediation as part of water recovery. Confirm with your contractor.
