"When I started working real-estate for family and friends in the Eastern part of Wisconsin, a dear friend and referral partner realtor, of mine, recommended Criterion Home Inspectors. I met Scott and was immediately impressed. I had outstanding inspectors back in South Central Wisconsin that had set the bar for HIGH expectations. Scott hit that bar and I've never looked back. Anytime my other inspectors are on vacation, I always give Scott for the opportunity to come over to do the inspection because I know he is going to have integrity, be straightforward, doesn't the report to cover his butt, not an alarmist, and definitely NOT a 'dollar' store inspector. He explains things in layman's terms to the buyers,(and sellers for pre sale inspections) answers all their questions. And if he doesn't know something, he says so and that he will find out, and DOES. Just a great guy and resource for new buyers and seasoned realtors. We highly recommend Scott!!"

"Nick was very responsive - he had great ideas about how to do things and shared all the information with us up front. He was prompt, punctual, thorough, cleaned up spotlessly, and made sure we were satisfied with the work he did. He was a pleasure to work with, and we will definitely call on him in the future."

"We were very pleased with the work done wrapping our old rotted windows and installing new gutters. Effort was taken to match existing trim and siding. Our only complaint was that we had to wait quite a while for the work to be done, but we are very happy with the finished product."

"This was a large and multi-layered repair process. The Paul Davis team was excellent to work with. Each one of their contractors was efficient and so easy to work with. They know their business and conduct themselves professionally and with great courtesy. I am delighted that the repairs are completed and I am grateful that this professional group did the work."

"The project went very well! Mike is terrific. The crew came as scheduled. Explained what they would be doing and did a nice job.The first part of the project involved trenching the basement floor along the three walls. This was the dusty and loudest part of the work since they use electric jack hammers. Make sure you cover everything. They did a great job cleaning up the area they worked in but you will still have dust. We had a minor problem and came to a mutual agreement for solution. Nice people to work with, great job!"

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