"My review is tiered because the overall service seems to run on tiers. The technician was great. Very personable and professional. 5 stars for his work. Your tests get sent to the lab. The lab explains the results and recommends a company for a DIY solution. This is where things start to fall apart. The company you get referred to has abysmal reviews and the sales pitch feels extremely predatory. That taints my opinion of the lab results which would be teamed up with a business they probably shouldn't recommend. We're planning on either an independent company locally to get a quote from for any remediations we will take or even see what home depot has to offer. In any event please read the reviews of BioCide, the company they will recommend you use. We're still not sure we even have a real problem if they are working together."

"Jeremiah came out and tested the air and moisture and other items to determine if I had mold in my basement. After getting the test results there was evidence of mold and he recommended a company that provides a do it yourself kit for mold remediation. (Not cheap). After getting the items and realizing that there was more work, it would have been better for me to let my insurance company handle this as I do have coverage for mold/fungi. Though having a professional do the work is expensive, from what Jeremiah mentioned, it does not guarantee that the work will be complete or the source of the problem taken care of. He mentioned most companies will take care of the mold but not necessarily the cause of the mold. For this I would have to contact another company."

Mold Testing and Remediation FAQs, answered by experts

Water damage occurs when your property or items suffer damage due to excess and unwanted water or moisture. The water could be present due to a natural disaster such as a hurricane or a burst pipe—water damage can be caused by many things. If necessary, contact a local water damage restoration company.

Yes, if installed correctly. Moisture barrier padding blocks dampness from reaching the padding core and subfloor, where mold loves to grow, especially in humid environments like basements. However, poor installation with gaps or loose seams can do the exact opposite, trapping moisture and creating mold problems. So, make sure to do your installation carefully or hire a professional.

Yes, a refrigerant leak is extremely toxic and dangerous to breathe. Refrigerants can displace oxygen in a room, which can lead to suffocation, loss of consciousness, serious health issues, and even death. You may also suffer from refrigerant poisoning, which can cause symptoms like headaches, nausea, dizziness, swelling of the throat or sinuses, vision loss, and a burning sensation in your eyes, ears, nose, lips, and tongue. If you experience any of these symptoms, you should seek medical attention immediately. In addition, refrigerant leaks are toxic to the environment and can cause permanent damage to the ozone layer.

Mold on windows forms due to excess moisture from condensation, poor ventilation, or leaks. Cold glass surfaces can attract condensation, especially in winter. High indoor humidity, lack of airflow, or dust accumulation are also contributors. To prevent mold growth, improve ventilation, regularly clean sills, and consider using a dehumidifier or sealing any leaks.

No, a dehumidifier does not actually remove mold. It only reduces the moisture in the room, which mold needs in order to grow. If you already have mold, you’ll need to do a deeper cleaning or call a pro to remove the existing mold first.
