We are professional service providers that take pride in our work. We work hard to provide the best service possible with integrity and accountability. We would love to help you so give us a call today!

"I had a black mold problem at my home. The evaluator gave me a price before any work was done. The crew simply went above and beyond the call of duty in the remedial process. On a scale of 1 to 10, I would give them a 15! Every member of the crew was extremely hard working, from Wilbur down to his 14 year old grandson. I like dealing with small, local, business, and I consider myself most fortunate and blessed to have found Will Hull and crew. I would hope none of my friends develops a black mold situation, but f they did, I would immediately recommend Wilbur Hull Nano Cleaning , They only perform necessary remediation to safely treat the house, thus saving money for the customer. They treated the entire house, which was a pleasant surprise to me. Overall, Wilbur Hull Nano Cleaning was superb! Pricing was Fair & Reasonable."

Mold & toxic material tests FAQs

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.
