"Outstanding service! I could not understand why my downstairs closet was extremely cold upon entry. During my first conversation with Phillip, he conveyed concern and dedication regarding identification and remediation of the unusually cold air. During initial visit, Phillip noted portions of closet were approximately 15 degrees colder than adjoining rooms. After conducting internal and external inspections of the nearby areas, he identified potential source of cold air. A couple days later with outside temperatures in the 20s, Phillip exhaustively sealed external areas of concern. A few days later, he came again to determine temperature differential within the closet. It was now much more comfortable with temperature only a few degrees below neighboring rooms! Throughout the entire process, Phillip was very friendly and knowledgeable."

We are a family owned and operated business. We are an independent 3rd party mold testing and mold inspection company. Mold remediation protocol written by the IICRC (Institute of Inspection, Cleaning and Restoration Certification) states that remediation companies should not do their own testing and testing companies should not do remediation, it is a conflict of interest. Not all mold projects needs to be professionally remediated. Our goal is to not only let you know if you do have excessive mold but how did you get it and how can you prevent it in the future by providing honest and outstanding service through dedication, hard work, attention to detail, integrity, and always focusing on our clients' best interest at hand. We know that the secret to our success has and will continue to be our satisfied clients. We will go anywhere in Maryland. Some of our clients include Governor Hogan, The Maryland State General Assembly, Property mangement companies, Insurance companies etc.

"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.
