"I was deducted $50 from my bank account. I thought that was the complete cost for the 45 minute inspection. I later received a bill for $750+ from this company. Never was there any mention of charges beyond the $50. Never was there anything in writing about a total over $800. I told the company about this. They said they had a recorded message of agreement and a copy of an agreement for this price. As of this date they have not been able to produce this documentation. I am very angry."

"Damian, was awesome! He was very patient and very thorough explaining the tests to be taken and explaining the results from the tests. He was never too busy to answer our questions. He was the right man to turn to. "

"I had Brett come to our home to test for mold because I’ve had an ongoing illness that Drs can never diagnose. He was so caring & did the testing within days of talking to him the 1st time. After the testing, he explained everything in detail and provided a list of things to improve the air quality in the home. I have never dealt with any type of contractor that was as thorough and really had our best interest at heart. He was honest, upfront with cost and I felt like I could totally trust him and his recommendations. If you are in need of mold or air quality testing, call Brett. You will be completely satisfied with his knowledge and care to make your home “healthy” again. "

"Best description? Superior work. Thoughtful interaction and patience with the many questions. This was my first experience with work of this nature. Bo, the manager, could not have been more helpful. Alex and Ford worked endlessly to mitigate the mold and at the same time were informative and attentive to my questions. Excellence is the word that describes both their effort and the manner in which they took time to educate me on the remediation. Bo went out of his way to respond to both issues and questions."

"Dennis was great to work with. He designed a pergola to match our odd patio space, so it is not a cookie-cutter pergola. The execution and design were top-notch. Dennis was responsive to our ideas and concerns and completed the job in a timely manner. Daily clean up was excellent. He needed to come back and touch up some of the wood where the stain was missing. While most people would have made this a half-hour job, he spent a couple of hours going over the whole piece and found places we had missed in our inspection. In addition to the new construction, he took down an old smaller pergola that was attached to our house and rebuilt it. He touched up the house paint as needed as a result of the demolition and rebuild. Everything looks great and we are getting lots of compliments. Dennis is an agreeable and intelligent gentleman and a very easy contractor to work with--someone who takes pride in his work and his reputation. I would hire him again in a flash! I almost hate giving him such a good review because he may not be available the next time we want his services!"

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