"Working with Damian was the easiest part of restoring my fixer upper! He's incredibly easy to work with, transparent and honest, and does great work for great prices. He managed to get started right away for me since the mold in my house was indeed toxic, and I couldn't be more grateful for the positivity he brought to what has been a very stressful situation for me. I couldn't recommend him more!"

"<p>Our 1950s era house had multiple layers of asbestos-laden flooring in the bathroom. We had Dirty Ducts come in and remove all the flooring before we started a bathroom remodel.</p> <p>They showed up on time and were done slightly faster than they estimated.  </p> <p>Since we were working with asbestos I was somewhat nervous, but they were extremely safety conscious and did a great job of sealing off the rest of the house.</p> <p>We are planning a bigger job in the future of removing kitchen flooring and will definitely be using Dirty Ducts again for our floor removal needs.</p> <p>Based on my overall experience with the company I would also generally recommend them for any other work.</p> <br />"

"Great! John was awesome. He was very professional and really knew what to look for and test. In the end, we did not have mold (thank goodness). We really appreciated John taking the time to inspect our home and providing us peace of mind."

"<p>Sure, it looked as if we had a giant octopus in our house (they used a drying machine that directed air through nozzles into holes in the walls and ceiling) but it was very effective. Once everything was dry, they tested it again with their special cameras/sensors, and then patched the drywall/ceiling and repainted. You honestly can't even tell anything ever happened.</p> <p>They laid paper and plastic down during the job, and wore booties--very important to me, as we have small kids and a dog. They were extremely nice, friendly and professional--also very important, as my husband works from home and youngest is only in preschool, so around much of the day. </p> <p>We ended up needing an electrician and plumber, and they made a recommendation and managed that so we didn't have to. The people they selected were equally professional and helpful.</p> <p>They were very busy, given the unusually cold winter and many busted pipes, but the communication was always clear and consistent, which is important.</p> <p>Our insurance company was very familiar with Certi-Dry and accepted their estimate without needing an onsite inspection, because of their history and reputation. That made us feel quite comfortable. </p> <p>I hope I never have to use them again, but would absolutely recommend them without hesitation to anyone else.</p> <br />"

"It went beautifully! All the mold was removed and everything looked new again. Chris explained everything to me in detail and I witnessed the product start doing its job. It was amazing! I love the fact that there is a 2 yr guarantee and is 100% environmentally and ecologically safe. I would recommend this to anyone."

"Jp improvements got back to me the same day I asked for a quote and scheduled an appointment the very next day to look at the damage. John showed up on time and gave us a estimate. Shorty after we asked John to go ahead with the work. In about two weeks the work was started and was found we had what looked like a toxic mold. John suggested a mold testing company to confirm. We found this testing company very helpfull. After testing it was confirmed to be toxic mold. After the results John could could finish the job safety, and did. This was all done with in five weeks which was remarkable considering a lot of people needed their services during this time period."

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.
