"There are so many mold remediation companies out there, but NO ONE IS AS GOOD as Mold One! Mike and Ron are compassionate, flexible, and willing to explain everything! They were there for me 100%, every single step of the way, during the most horrific time of my life. My prior mold remediation company had been negligent, leaving me exposed to toxic black mold on a daily basis, and Mold One took care of all of it--with no mess or dangerous dust. Mike was LITERALLY a life-saver. There are so many mold remediation companies charging 10 times as much, and doing a far worse job. It is very difficult to find a company you can fully trust to put your interests first (so many say they do, but when it comes down to it they overcharge or cut corners, leaving you in danger!). I hope Mold One becomes the partner of choice for all the major insurance companies, because they are BY FAR MORE COST EFFECTIVE and thorough than any other company I've found."

Biohazard Remediation FAQs, answered by experts

According to the College of Agriculture and Life Sciences, there are over 10,000 kinds of mushrooms, and some are harmful to both humans and animals. However, not all mushrooms are harmful—some feed on thatch and wood, which provides nutrients for grass and plants. 

But unless you’re a mushroom expert (mycologist), it can be hard to tell poisonous mushrooms from non-poisonous. So if you have kids or pets (or both), removing them is the safest route to take.

Inhaling black mold spores, even from behind walls, can cause people to have a wide variety of potential health issues. Some people may only notice a few breathing problems, while others can become quite sick with symptoms related to severe allergies. Constant exposure to mold spores can lead to lung infections and other long-term health problems. If you believe you have black mold inside your walls, you will want to reach out to a pro for an inspection and for advice on how to take care of the problem before it causes severe illness.

Symptoms of sewer gas poisoning include nausea, dizziness, extreme drowsiness, and headaches, according to the Wisconsin Department of Health Services. Exposure to higher concentrations for long periods of time could also lead to unconsciousness due to a lack of oxygen, aka suffocation. If you think you’ve been exposed to sewer gas for a dangerous amount of time, seek medical care immediately. Do not return to the site of exposure, after you’ve received medical care, call a pro for help.

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, limewash is free of volatile organic compounds (VOCs). Made of lime and water, it is eco-friendly, breathable, and toxin-free. Most synthetic paints have low to high levels of VOCs, which causes their irritating odor, which can have adverse and long-term effects on your health. Conversely, limewash consists of crushed limestone, which undergoes burning, mixing, and aging before being diluted with water—natural pigments add coloration.
