Dark mold growth, while common, can cause allergic reactions and various symptoms even when in the attic.
Great project which ultimately lowered the indoor humidity by 20% making it more livable for the family, storage where there was none previously, and much more healthy from and indoor air quality perspective (no stinky bacteria).

"When I went looking for flooring at a local store, the man said there was a good chance the tiles and glue were asbestos. My research indicated I could just cover the floor (encapsulate it) or remediate it. Even though it was expensive, I thought it best to remediate it. I used Angi's which is what I ALWAYS do and looked up service providers. I called a couple of them and got prices. Environmental was not the cheapest, but Maximus made me feel comfortable. He not only reviewed what needed to be done in the basement, he advised me about other things, as well. I felt like he really knew what he was doing, and he spent time with me. He gave me options, and I think he went above and beyond."

"I was extremely pleasantly surprised when the inspector showed up because it was Dulce Casas and she was absolutely amazing. As a woman, it was so fricken cool to have a woman to the inspection and give recommendations. She was always timely in her responses and even helped us find someone to do the repairs we need now that the mold is gone. Absolutely highly recommend this business and will be using them any time necessary in the future."

"Mike was awesome. We had a contractor cut a wall that we later learned was asbestos. I have 3 kids and was concerned that we had opened up Pandora s box and wanted to know more about the air quality and if we needed remediation. Mike came in quickly and took samples of the wall and air samples of multiple rooms. He came back within one day confirming the wall was asbestos and within 3 days we learned that the air was free of asbestos. It was great service and great to know that the air was ok. We now know more about our home and are making plans to address the walls in the future. Mike will be part of our plans once we do go to removal."

"I did not know I had a high radon level. I contacted Gardner and they installed a remediation system. It took 4 men 9 hours to do the work. When it was done it looked professional and they cleaned up as well."

"US Waterproofing was great. Finished job looks terrific and they did a tremendous job cleaning up after themselves. In particular, it appears their dust remediation system really did the trick because I was expecting a ton of dust from the jack-hammering and their really isn't ANY to speak of. I want to give a particular shout-out to the crew that worked on my job. The initial work was on a cold, rainy, miserable day and those guys went in-and-out of my house all day long lugging buckets of dirt by hand. Hard to think of a more thankless task in worse conditions--but those guys worked their butts off. I was thoroughly impressed. Wish I knew their names--but thanks so much. Great work."

Biohazard Remediation FAQs, answered by experts

Yes, when you add shock to your pool, it raises the free chlorine levels in the water, which in turn kills bacteria and algae. Although you may think of using algaecide to get rid of algae, it’s actually a preventative measure.

Additionally, killing the algae alone isn’t sufficient to get your pool back to normal. You need to vacuum, brush, clean the filter, and balance the water.

Using bowls of water for humidity can be an effective way to increase the humidity level in a room, but it's essential to consider potential risks. Placing bowls of water near heat sources might pose a hazard as they could spill, causing damage or creating slip hazards. Moreover, stagnant water can become a breeding ground for bacteria or mold (you really want to get rid of black mold stat) if not changed regularly, potentially negatively affecting indoor air quality. Water bowls can also accidentally spill onto surfaces, causing water damage to furniture or flooring. Regular maintenance and cautious placement can mitigate these risks.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.

If your sill plate is visibly rotting, you need to call in a structural engineer immediately to make an assessment. They will determine if the sill plate needs repair or a full replacement, and they’ll also provide you with a protocol that you can give to a foundation repair specialist to get the work done properly. After your repair pro completes the replacement or repair, you should address the underlying issue, which could involve installing a dehumidifier, adding ventilation under your home, grading your land away from your foundation, or installing waterproofing measures.

You can experience respiratory problems if your return air vents are dirty. While this doesn’t necessarily mean dirty return air vents will make you sick, they can exacerbate symptoms of respiratory illness, such as sneezing, wheezing, and coughing. This is due to the extra contaminants in the air, which may include allergens and dander that can affect people with allergy sensitivities.
