When you have mold, making the correct decisions right away is critical. Whether it is mold in your home, school, place of work, or apartment there are many factors to consider. Are you going to be involved in a mold lawsuit? Will you be seeking property damages? Is anyone sick from mold exposure? Will you be seeking medical damages? Will you need expert witnesses? If so, what kind? Do you just want to test to be sure your environment is safe? Do you need post mold remediation testing to ensure a good job was done? These and other factors are questions which need to be answered before any environmental testing starts. It is important to know what your goals are and why your testing. Different goals require different environmental tests, i.e. medical damages and property damages require different environmental tests to prove your case in court. Tests that a common, or inexperienced, mold inspector would not typically use or know to use.

"They did a prompt professional job. I received the report in about 7 days. Mold was found in the air due to high humidity in the air. All of this seemed OK but then I was forwarded to the Biocide company that tried to get me to buy a DIY mold remediation kit. There a time pressure to buy the kit for the best price at $2400. They said the nature of the mold would require a hazardous work fee from any remediation company that would cost from $12,000 - 18,000. This is when I started questioning the service I received. My pulmonologist also looked at the test results & said the mold levels did not seem too bad. Also, the humidity readings on my house thermostat did not read the high level that the report stated. So, I do not know if there was any value with the service & I am not sure if I would recommend them. The only way to really find out would be to call in another testing company but I did not want to spend another $660. So, I had the remediation work done for $1900 & was satisfied."

"I had a poor experience. I hired this company to do a mold assessment in my apartment. I dealt with the owner. First, he requested cash or check payment only. He made an appointment and did not show up or contact me. I had to call him. In one of the rooms, the pipes above and whatever else the cause of the leak was, had been leaking repeatedly for 40 years, and the plaster constantly replaced. I was worried about mold ABOVE the ceiling on the beams and studs and not just the visible mold on the ceiling plaster and I worried it could be black mold. He did not seem to listen to what I told him and he did not use a water meter to check for saturation or a borescope or any other tools except taking a surface sample and air sample (the borescope and water meter I did not know about until after I had paid him for this inadequate job). He did not mention anything I said in the report. He was also rude and unkind and never provided me with a receipt."

Mold Testing and Remediation questions, answered by experts

Although mildew is less harmful than mold, that doesn’t mean it’s safe. Breathing in even small amounts of mildew can cause serious health complications, especially in those with weakened immune systems. If you find any mildew in your home and can’t completely remove it easily (and there are elderly or sick people living there) you should call a professional right away.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.

The symptoms of mold exposure for sensitive parties include a skin rash, runny nose, coughing, sore throat, burning eyes, and even more severe allergic reactions. If you notice signs of mold exposure, contact a medical professional right away.

Black mold on wood is a very serious issue. Besides compromising the structural integrity of the wood, it poses significant health risks. Stachybotrys chartarum, commonly known as toxic black mold, produces mycotoxins that can lead to respiratory issues, allergies, skin irritations, and other health problems. If left untreated, it can spread rapidly and compromise the structural stability of the affected wooden structures. Immediate remediation and preventive measures are essential to mitigate the risks associated with black mold on wood.

Mold remediation is required if the mold growth covers more than 10 square feet of an area or the mold spore concentration is above 500 spores per cubic meter of air. You should also seriously consider remediation if there is a lot of water damage along with mold growth or if you suspect your HVAC system has been contaminated with mold. Remediation is also crucial if the mold damage has been caused by sewage or other contaminated water.
