"I very rarely write endorsements, but in this case, my experience was so satisfying that I felt an obligation to share. I have no connection to Marty, other than hiring him and his company, I have not been paid or discounted to write this and I never would sell my opinion. I had massive amounts of water leaking into my finished basement during the July 2017 record rainfalls. It wasn't the first time to get some water, but this was way more than normal. Carpet smelled really bad. I was sneezing and couldn't spend more than a few minutes downstairs to do my laundry. I contacted 2 contractors listed on Home Advisor. Marty from ATI called first thing the next day. He rearranged his schedule to see the damage after I told him I was anxious to get it fixed asap. He arrived on time and texted before he arrived. Very professional. Highly qualified. I was impressed with his scientific knowledge of the problem. He was NOT selling me on his services, he explained how the damage occurred, how to clean it up and what would need to be done to fix it. He discovered potential asbestos tile underneath the soaked carpet. I told him to take it all out and remediate mold and asbestos. I chose to forgo the prior testing to expedite the repair. He gave me a quote on site and I gave him a down payment. He and his employee, Wyatt, arrived 10 days later and worked more than 12 hours that day in hazmat suits and masks. The amount of work needed was unbelievable. They sealed off the basement with plastic and put up notices of the hazards. They came back another day to complete outside drainage of gutters. I asked about some other asbestos abatement and Marty prepared a proposal for exactly what I requested. I didn't hesitate to sign another contract for the additional work based on the quality of their work. I'm extremely pleased with their work and the results. I could add so much more to this review for all the things they did above and beyond the contract. One thing they did was to help move an old commercial oven from the basement when a buyer showed up in the midst of their remediation work. I thought the pricing was reasonable. The other quote I received was from someone who outlined a completely bogus remediation using essential oils and a $1000 fan. The other contractor told me he would not be wearing the hazmat suits and masks. That contractor's proposal was close in price to ATI, but I am certain the outcome would have been horrible. I spent $3250 on the first remediation and will spend another $4000 on the second part of the remediation."

"I was impressed with the extent of knowledge that the tech exhibited upon his first visit. He was concerned and as interested in knowing the source of my problem as I was. He had a very quick understanding of what my needs were. I believe that he had the most reasonable explanation for the cause of the mold and more importantly, his company was going to handle it in the manner that I thought was safest in every way for me and my household. His explanation seemed to stem from experience and I was confident that my health was protected while doing this mold removal process. I appreciated not being scared into doing this removal."

FAQs for mold & toxic material test projects in Madison, WI

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.
