"It was frustrating. I bought the service because of an Angie's List promotion. When I received the package I opened it and saw what it was and set it aside. I was very busy and planned to get to it in a few days. I had to go out of town for a few days, then I had a ridiculous string of bad luck with multiple car breakdowns. I have a neuromuscular disease so everything I do is very difficult and exhausting. With so much happening, I forgot about the test kit. Then after a couple weeks I get a call from Mold Lab asking about the kit saying it was past the due back date and they were going to charge me $25 a day late fee on the pump. I was stunned! I opened the box and there was nothing inside saying it was due by a certain time. I re-read the Angie's List ad and there was nothing there either. The lady was very rude and kept interrupting me saying the same things over and over like maybe I would finally understand if she kept repeating it. I understood the first time. She wouldn't listen to understand I didn't know about the deadline but now that I was made aware of it I would do the testing that day and ship it that day. What else could I do? That wasn't good enough she had to repeat her lecture a few more times. After sending it in I was told I would receive a text when it was complete and I would receive an email with results within a few days. After a month I called and the same lady answered. She claimed to have sent an email, but didn't know the date and told me to check my junk mail folder. I checked everywhere but had no record of it. I explained I hadn't received the text either, she had no response for that. So she sent an email while we were on the phone and I received it immediately. I printed out the results but without the proper training or experience in laboratory sciences it was basically useless."

"Very pleased with the entire experience. Came out and did a very extensive job of reviewing the cleaning companies work. Checked lumber moisture levels, looked for visible mold and ran three air test samples (basement, main floor and outside for control). Had results in a couple of days. Very responsive and always returned my calls."

"What a treat to find a company so conscientious about time, quality and building a relationship with the customer. They actually came and cleaned all of our carpets throughout the house before we moved in at the beginning of August. They did such an excellent job that, after our furniture arrived, I had them back to do the couches and chairs. <br /> During this second visit, they looked back through the house to see what the carpet was looking like and treated an area of the living room that they thought should have come out better. I showed them an area at the bottom of the stairs that our (horrible) movers had made when they brought in the washing machine. He took care of that for free. We also had an eye liner pencil issue on a bedroom carpet; I asked for advice on how to treat it and he cleaned it for free! (Black on cream carpet and you couldn't tell where the spot had been.) They then left a free can of their spot cleaner and said they'd bring any when we needed it. <br /> But the biggest selling point for me? I have a special needs child who is fascinated by things like garbage trucks and how they operate, recycling plants, moving companies...and apparently, carpet cleaners. He engaged them in conversation both times (different people) and both times they responded so kindly, answering his many (and frequently repeated) questions and then made his whole day by showing him how to use the equipment and allowing him to help. He's 12 - and they told him that when he turned 16 and was looking for a summer job, he should call them. You would think he had just won the SuperBowl! <br /> Cannot recommend them highly enough - and won't even consider using anyone else after these experiences. <br />"

"I've had a flooded basement for two consecutive years requiring the installation of new drain tile.  This resulted in water damage/mold issues.  Also had all carpets and upholstery cleaned throughout the entire home.  Jay, Cannon, and Shawn were all wonderful; they went above and beyond and their customer service was exceptional.  They provided punctual, dependable, and reliable service.  I appreciate their honesty and integrity and would highly recommend their services to my family and friends.  Thanks Guys!"

"This spring there were quite busy with a lot of water problems. I live about an hour away, so it took some time to get someone here but once they came, we scheduled an appointment and went from there. They were professional and complete. The room is now mold free. Thank goodness. There would have been no way I could do this on my own. <br />"

"It went very well. I am allergic to molds. They were very thorough. It was the first time i did business with them. The first person they sent out wasn't the owner of the company and he was a little timid. I had to have the owner come out and give me a thorough analysis. I will give them a "B" because of that. I did not compare the prices but the rate was good."

"Jo is a 100% top notch professional. PROMPT, FAIR, and most of all HONEST. The VAT in my 1,000 sq. ft. basement is gone. The black mastic is gone. He did an INCREDIBLE job. I couldn't have asked for a better experience. If you are considering Asbestos abatement, LOOK NO FURTHER. THIS IS WHO YOU NEED TO CALL. Jo and his company (Airtite Environmental Services LLC) will provide you with an honest quote, do honest work, and follow-through on his commitments with no bs, and no sale-sy crap. If I could rate this business higher than 5 stars, I would. I am grateful I found Airtite, and grateful to have hired them."

"PuroClean showed up and began immediately to dry the damage floors. They also worked with our insurance company helping them understand the damage caused by the leak in a very short time, like less than a week. They were professional and provided Value for the their work including drying the damp areas from below the floor and above removing the possibility of a mold issue."

FAQs for mold & toxic material test projects in Marshfield, 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.
