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.

"The mold testing is fine. The mold remediation company is very sketchy. Just buy some air purifiers."

"I paid this company $600 to test the air in my detached garage. The results showed Cladosporium, which many professionals told me is extremely common. What happened next was one of the most uncomfortable experiences I’ve ever had with a home-service company. They sent me a remediation proposal for over $45,000, and in my personal opinion the scope, tone, and sheer intensity of the warnings felt completely disproportionate to the situation. The estimate was filled with pages of dramatic health claims that, to me, came across as fear tactics rather than professional guidance. When I asked questions, the owner was extremely rude and dismissive on the phone. The whole thing felt pushy and uncomfortable. After leaving an honest review, things escalated in a way that shocked me. The owner contacted me and offered a refund only if I signed a notarized disclaimer that he drafted. I personally found that very unusual, and I chose not to sign anything. What concerned me even more was what happened next: after I declined to sign the document, a negative review suddenly appeared online about my wife’s business — at our home address — claiming she had done work for him and stolen $600 from him. In my experience, this was completely untrue. My wife has never worked for him in any capacity. In my personal opinion, it felt retaliatory and deeply unprofessional. I ended up getting several second opinions from other mold professionals, all of whom felt the quote I received was excessive for what was found. Based on my experience with the customer service, the tone of the estimate, and the way things unfolded afterward, I would strongly recommend that other homeowners get multiple quotes before agreeing to anything. In my personal view, the way this situation was handled was alarming, unprofessional, and not in the best interest of the customer."

Mold Testing and Remediation questions, answered by experts

Professionals are trained in identifying hazardous materials and utilize industry-approved methods for safe handling and disposal. They adhere to regulatory frameworks to protect health and the environment, ensuring all materials are disposed of safely and responsibly.

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.

While an air purifier can trap mold spores and stop them from spreading around your home, it’s not the most effective solution for tackling the problem. Mold is caused by excess moisture and humidity, so there’s a good chance you have an issue somewhere else in your HVAC system that needs to be addressed.

If you're wondering about black stains on brick at your home, the answer is that you're not looking at efflorescence. While efflorescence can be darker when certain types of salt are involved, black staining is caused by carbon staining, pollution from vehicles, and chimney soot. Black stains can also be caused by organic materials like lichen, algae, or mold.

A funky smell is the first indicator that mold or mildew is present in your home. You may also notice that you or your household members are suffering from increased allergies or respiratory issues. You should check the most obvious areas first—like your bathroom or anywhere there might be leaks—and if you still can’t locate the source, look under the floorboards.
