"Helped me with questions about air quality in my home and specific causes and treatments when tests proved I had issues. As a result, I am well on my way toward a cleaner, safer environment. I am a Vietnam era vet and the technician (not giving his name without his awareness) upon realizing that showed tremendous respect."

"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."

"We hired Jeff to give us pre and post mold remediation air quality tests, and I am so glad we did. Jeff was extremely knowledgeable and had no conflict of interest on the outcome of the results since we had a different company doing the remediation. We actually had to go back to the mold remediation company when his air quality report did not pass clearance, and he was our chief advocate in getting the company to come back and do further remediation. He has been a great to work with because he is not only an expert but is a caring individual, and I would recommend anybody use his services. He also is licensed to test for asbestos, which is our next project before we remove our popcorn ceiling!"

"Very personal service. They gave practical advice, like don't pull up your moldy wet carpet yourself. Their workers were very friendly, trustworthy, and hardworking. We could ask a thousand questions and all were answered. Their cost was reasonable considering all the drywall, paneling, and carpet they had to remove. My family was coming for a visit, and they fit us into their schedule right away. Service you can trust."

"My fiance and I recently moved into a new home and were concerned about our air quality since we have pets and plan to raise a family there. We both have allergies and it is an older home so we were also concerned about the smell. We did an in-home radon test and our level came back at 2.9 but we wanted it lower as a precaution. A mitigation system was not recommended and based on our specific needs Brandon suggested a Breathe EZ air filter. It was installed quickly and we’ve already noticed less dust and less irritation from allergies. It also got rid of the musty smell! The filter was a perfect fit for us and we appreciate Proper Environmental for educating us on all of our options so we could make the right choice for our family."

"It was very good. My husband was there when they came. I think they were just professional and reasonable. They did the dryer vent. I wasn't there when it was done but I think my husband was pleased with their professionalism and performance. We would absolutely use them in the future."
