Customers say: Quality work

"Keith fixed our pocket door after it came off-track. He was friendly and professional, first coming out to have a look at the problem and ensure he would have the right materials, then coming back to do the work. He found the parts, fixed the door, took apart and replaced the molding, and charged a very reasonable price. The door is working great! Highly recommend for everyday household fixes, but I hear he can do larger scale projects as well!"

"Great! Gary was very honest, had a firm handshake, and did not try to oversell me. He explained the big picture and then made recommendations on what would be the most cost efficient. He also explained the equipment he was using and the process of how the results would be received. He was very thorough. The price I paid was for more than the regular mold testing and I would definitely recommend him again!"

"Well after not knowing any better I removed some 9"x9" vinyl tiles and black mastic from my basement Cement floor and didn't take any safety precautionary measures. After doing some investigation after the fact I found out that the tiles and mastic most likely contained asbestos. Being that I have a 9 year old and a 5 month old in the house I became concerned of possibly asbestos being in the air of my home. I called numerous places to get some help and nobody either answered the phone or everyone said they were to busy for the next couple of weeks to come to my house to test the air. I was finally referred to Bret at IAQ Diagnostics and I spoke to him over the phone and told him my concerns. He was very helpful over the phone and described everything his air quality test consisted of and the price. The price was a little pricey but being I had a 5 month old in the house I rather be safe than sorry and wanted peace of mind. Brett came over the next day on time as planned and was very polite and explained his testing process again. He ran a testing machine for two hours and then went back to his lab to get the results. He called me a couple hours later with my results which came back with the results I wanted to hear. Brett also emailed me a detailed report with all his State of WI licensing information so I could keep for my records. I would highly recommend IAQ Diagnostics."

"I was in the middle of a recent home Refi to get cash out for a new roof and new windows but the credit union wanted a professional report of some interior water damage that was noted during the appraisal process. Donn, from Anderson Home Inspection, was my inspector 20 years ago when I originally purchased my duplex. I contacted Donn and explained the situation and he was very understanding of the need and urgency to get the report for the bank. We scheduled a time 2 days later. Donn quickly assessed the interior water damage and then used his very cool drone to inspect the roof. He took pictures of the roof, interior water stains, and the attic. His report was completed and I submitted it to the credit union. His determination was the interior water stains were cosmetic and not structural. They were due to the poor condition of the valley and chimney flashings and would be corrected this spring when the roof is replaced. Thanks to Anderson Home Inspection my Refi proceeded without further issues and I'm on my way to a new roof and new windows. I have many friends that have used Donn's services and never hesitate to recommend him to anyone."

"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."

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