"They came quickly to inspect the property. It turned out there is no asbestos so they were not needed. They were prompt and helpful nevertheless. If it had been asbestos, we would have hired them."

"Mike at Mold One was incredibly helpful. He gave me great information and lined up an appointment quickly for mold remediation. My wife has struggled literally her entire life with being sick and unwell and having chronic headaches and fatigue and poor sleep and mood swings and food allergies and the list goes on. We've been to countless doctors, bought countless supplements, tried several diets, done allergy testing, been to chiropractors, done hormone replacement therapy, etc. We recently found mold in our home and began looking into mold as a possible cause for her poor health. All of a sudden, things started lining up. Mold sickness symptoms are myriad, so nearly any symptoms could fit under mold sickness as a possible cause. We did a TON of research, found Mold One, did more research on their paracetic acid dry fog technique and found research articles from 3rd party labs supporting the effectiveness as well as safety of the procedure. My wife was pregnant at the time of treatment, so we wanted to be 100% sure that the treatment would be safe for her and for our baby and other young children. Once we were satisfied with the safety of the process, we hired Mold One and they had us lined up within the week. We only had to be out of our home for about 5 hours for the process. Upon returning, there was a faint vinegar smell in the house. My wife slept better that night than she ever had, and within 2 days, she was feeling SO MUCH BETTER. In fact, over the coming days/weeks, even though she was 8 months pregnant, she felt better then that she or I ever remember her being. She had energy, her mood was better, she slept better and needed less sleep. This was truly miraculous. We had tested the house for mycotoxins through Mycometrics prior to hiring mold one and found very high levels of Aspergillus. About a month after the mold treatment, my wife did a urinalysis through Great Plains Lab for mycotoxins and she was off the charts for Aspergillus. The body can take up to several years of detox to get all that out of the system, so no surprise that a month later it wasn't all gone. This was just proof that that mycotoxin was present at very high levels in her body as well as our home. And here's another shout out to the customer service and generosity of Mike and Mold One. About 2 months after the mold treatment, I was working on replacing my roof. A micro-storm came out of nowhere while I had the roof open and absolutely SOAKED everything. We had water dripping through the light fixtures inside and huge water spots showing all over our ceilings. This was hugely discouraging. After the storm passed, I called Mike and explained the whole thing and asked his advice since now we're a pitri dish for mold. Mike offered to send his guys back out to re-treat our home for free and consider it covered by warranty, even though it would have been easy and obvious to consider this new water damage not covered by warranty. I can't say enough of how great Mold One and Mike have been, and what a life changing impact their mold treatment of our home has had on my wife. Thank God that he led us to this solution for my family's health."

"Overall I was satisfied with hiring this company, as my main concern was where did the mold come from (and if it came from my 2 yo roof and I needed to file a warranty claim, then I'd need the paperwork for that). The home inspector who did the inspection was very thorough and managed to also give us other useful pointers which helped out. In the end, the final report we got was a bit oversold on what it would look like and be used for (the remediator gave us the same recommendation without us spending the money to get this), but it gave us the piece of mind that it wasn't the result of the new roof, so I'd have to say the value was there. The only issue I had was a scheduling snafu which made me have to reschedule, which really extended the time it took to get this completed. I would recommend hiring them, though."

Biohazard Remediation FAQs, answered by experts

The high temperatures of steam cleaning are effective at removing mold from walls. Just ensure you properly ventilate the room and use an N95 mask, gloves, and goggles while working. If there is a lot of mold, it’s better to consult with a local mold removal company. They can safely eradicate lingering mold spores and identify any underlying problems.

The primary difference is that black mold (Stachybotrys chartarum) is considered toxic and more dangerous than regular mold. It can produce harmful chemicals called mycotoxins, which may lead to severe health issues like respiratory problems, skin irritation, headaches, and other long-term complications. While regular mold is rarely toxic, it can still cause allergic reactions and respiratory irritation. Visually, black mold often appears dark—green, gray, brown, or black—with a fuzzy texture, whereas regular mold can be almost any color. Black mold is less common and typically grows in areas with severe water damage. Regardless of the type, you should not ignore any mold infestation in your home.

A solution of bleach and water is the quickest method for killing mold, but not always the best for DIY use. For safe mold and mildew removal, consider using cleaning products like borax, vinegar, and hydrogen peroxide—though never combined with bleach—for a quick and safe clean.

Deciding whether to use bleach or vinegar to eradicate mold on concrete is dependent on personal preferences, safety concerns, and the severity of the mold issue. Bleach is a powerful disinfectant that kills mold and its spores, but its strong fumes and potential health risks make it a more aggressive approach. It's generally a better option for handling outdoor concrete stains. White vinegar, however, is a safer and environmentally friendly option that can eliminate mold. Although it may take longer to show results, vinegar has a milder odor and is less likely to cause discoloration than bleach.

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.
