    Took sample of flooring to check for asbestos, Come to find out the sample was never sent in for testing. The paperwork could not be found.

    They came to remove the green tile from basement floor, Charged over $8000. They left one heck of a mess. The floor, walls ,ceiling and the windows were covered in asbestos dust from the under coating of the tlle, We tried vacuuming and the very fine dust from asbestos and floor achieves clogged up the filters and motor on vacuum cleaner.. It was so dusting we couldn't get it,, We finally dumped water on it and scooped up with shovels. Besides the dust all over the lower edge of walls had sledge on them.. We called them and they said it was normal to leave dust all over, and it was our responsible to clean up, I think they took advantage of a very elderly couple. When they came to give a bid Marty said everything would be cleaned up when they were finished. Marty said the floor would be ready to have new flooring put down.

    ATI did come out to test for radon, but showed up 8 hours later than scheduled which interfered with our evening plans. After testing another person came by to pickup monitor. Had no idea who he was. Still waiting for copy of test a week later.

    The owner of this company was extremely knowledgeable and answered all my questions, even some not relating to the project. Highly recommend!

    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.

    5.0 Carol K. Verona, WI

    I was experiencing unexplained headaches, primarily when I was in my home that I purchased in December. I wondered if I had an indoor air quality problem. Not only did ATI find a gas leak that others missed, but Marty also discovered that the outside vent into which inside air was expelled was stuck shut, causing the carbon dioxide level in the house to be high. Further, he "discovered" a built-in dehumidifier that I'd turned off because I thought it was a humidifier. Obviously, I don't know much about building features, but neither an inspector, duct cleaner or furnace repair person did as thorough a job of explaining things to me as Marty did. He exceeded my expectations.

    5.0 Platteville, WI

    He is very smart and knowledgeable about everything for the local laws and regulations and has a very good eye at catching things that normal people would miss. I have dune construction and every thing to do with a house from pluming and electrical and we went head to head catching things very smart even caught things i wouldn't have. Best I've seen so far
