"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 was good for what the service is. The technician was a postal worker and home inspector. So mold test company appears to be brokers. Their pricing was competitive from other quotes I received but I honestly think it was pricey for time spent and what they do. But like I said the price was pretty standard from the companies I called, in my opinion. But the technician was attentive and knowledgeable, and friendly."
