"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

It is not advisable to shower in a bathroom contaminated with black mold due to the potential health hazards it poses. Inhaling mold spores during showering can trigger allergic reactions, respiratory issues, and skin irritations, especially for individuals with pre-existing allergies or respiratory conditions. Prolonged exposure to black mold can result in severe health complications. It is crucial to eliminate any black mold problems in your bathroom before continuing with showering to ensure a safe and healthy environment.

Removing mold yourself can be dangerous. Always wear protective gear to cover your skin, face, and eyes, and wear a respiratory mask to protect your lungs. It is most recommended to only remove small areas of mold on your own and leave large mold growth to professionals. Mold growth can also be persistent. Without addressing the root cause, DIY surface cleaning can be ineffective and temporary.

No. When dry, mold enters a dormant state. While “sleeping,” the mold won’t multiply, but when it encounters moisture again, it springs back to life, releasing spores. That's why it's crucial to not only control humidity but also actively eliminate mold to prevent its resurgence and further growth inside your home.

Beyond looking for visible signs of mold in a home, you can tell if your house has mold by undertaking testing. You can hire a local mold testing company to run the test for you, giving you a sure answer. Professional testing is often the best way to determine whether you have mold, as some types of mold may grow in places where you can’t easily see them, such as behind walls.

You can do more with a home test kit than just check your water’s hardness. There are a few types of tests. The first one is simple and involves a strip that checks your water’s pH balance. The second and more thorough option is a master test kit, which shows your pH plus the presence of nitrite, ammonia, and other elements through color shades. Unsurprisingly, the most thorough test is one you send to a proper lab for analysis
