"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."

"Steve came to our home same day as we placed the order. He was very thorough and shared his insight with us about how to proceed. We had the analysis within two days and Steve helped us interpret it and plan our course of action. He answered our follow-up questions promptly and gave us recommendations on qualified mold removal contractors. We are very pleased with his work and would recommend Mold Consultant to others."

"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."

"Several companies told us the job was too small, but Quackers came out promptly when I called to get an estimate. Very happy with the outcome. While nobody wants to need to use a waterproofing company, it's nice to know there are some good options out there besides the really big and over-priced companies."

"It went well living up to the many excellent reviews by previous Angies List reviewers. They remediated the mold by cutting away affected drywall, applying mold killing material to the surrounding walls in the cold air duct. They set up a containment area in the closet adjacent to the cold air duct and used HEPA vacuums to cleanse the containment area and air of mold. Their estimator found moisture in the floor in front of our toilet when he came to do the estimate. A plumber who who found the leak and fixed it without entering the mold affected area found a badly rusted flange under the toilet with rot. When the workman from Mold Solutions came to alleviate the mold problem they cleaned up the area around the sewer pipe and flange and applied anti-mold material. That awaits a plumber to fix the toilet connection. Mold Solutions did the minimum amount of disruption to the cold air vent in eradicating the mold. As a result repairing that duct (which also serves as a resting place for things in the closet), will be much easier and less costly than I had feared. In cleaning up the sewer pipe and flange in the bathroom floor (a bonus not in the estimate) I could see that the repair would be less costly than it originally repaired. Mold Solutions job was done in three hours in the early afternoon of a Tuesday, followed by the HEPA fans operating until the next morning. Mold Solutions did a great job of finishing and cleaning up in one hour on Thursday Morning. I highly recommend them."

FAQs for mold & toxic material test projects in Saint-louis, MO

Some companies offer a no‑cost phone or video consultation that screens for red flags. If the discussion points to a real issue, the pro will recommend a paid on‑site inspection. The complimentary call clarifies whether you need full testing, but it isn’t a substitute for samples, lab work, or a written report. Always confirm what the free service covers before you schedule.

A standard inspection, which includes basic air and surface samples, takes an average of two hours. If the pro needs to probe hidden spaces, such as wall cavities or ductwork, plan on up to six hours. Extra time allows the inspector to reach tight areas, collect additional samples, and document findings. Lab analysis is a separate process and often adds several business days to the overall timeframe before you receive the full report.

Mold thrives where moisture lingers and air flow is poor. Common hotspots include bathroom walls, kitchen backsplashes, window sills, HVAC vents, fireplaces, crawl spaces, and enclosed attics. Check these areas regularly—especially after leaks or high‑humidity weather—to catch growth early and avoid costly repairs.

Unchecked mold can knock 20% to 37% off a home’s market value because buyers worry about hidden damage and health risks. Even after remediation, visible staining or a history of major moisture issues can still lower offers and prolong the time on the market. Addressing mold quickly protects both your property’s structural integrity and its resale appeal.
