"The very best experience! I have a so. With severe asthma and lately have not been able to control it. A friend mentioned having the house tested for mold and we set a company from home advisor who didn t show. I called around 4 more people 3 of which I felt like a number, to busy, very high quotes, and then I got Wilbur Hull. Explained what was going on and he had compassion and was able to come out for a test same day! When he got here he was thorough and I was willing to spend whatever to test all of the rooms. He was very thorough and explained after a free inspection that I could test but, it could and would be a waste of money if I had to treat when the results came in versus just treating anyway and skipping the fee of testing. It was a no brainer and a great feeling he went out of his way to save me money. I was skeptical on how it would kill everything but with research and his knowledge it really is a fantastic product offering more then just mold remediation. We treated the entire house for close to what other companies wanted just to test! His crew was above and beyond helpful moving things, explaining, and dealing with a paranoid mom. After they left the house smelled fantastic in areas once muggy (laundry room/mud room) and I could see positive changes in my son. About 10 days later cleaning I found apparent mold in a bench seat that would have been blocked/buried when they came initially. I called him to come back out admitting fault of it not being pointed out prior on my part to get a quote of hitting that spot I had blocked. He went above and beyond sent his crew who re-did it with a smile and asked about my son. A true family man, company, and crew. We will continue to use their service annually as precaution and will recommend them highly to everyone. We need more businesses like this!"

"Will (owner) was very prompt in responding to my questions. I decided to proceed directly to treatment (skip testing) due to a prior mold problem in basement. Because he had an opening in his schedule that week, I decided to take care of the treatment right away. His team was very polite and professional and answered all of my questions. It took only about an hour to treat my entire house. Very happy with the service I received."

"The company sent a packet with instructions to provide samples from two sites. We returned these in the Priority envelope provided. Within a few days we received an evaluation of the mold. It does not appear to be a serious problem. I would have graded this work higher if the company had provided general guidelines for remediating the problem. We were relieved to find the problem not serious, but would have appreciated more clarity, such as a simple page outlining safe and unsafe do-it-yourself procedures materials materials. (Suggestions I found online, such as whether to use vinegar, bleach, etc., were sometimes confusing, even contradictory.)"

"Office communicated. Had a signed contract with pricing for the install. I was able to pay via credit card very easily over the computer. Installer was professional and cleanliness up after himself. Owner called to verify my satisfaction with the work. Post radon test was below the allowed amount of radon. Highly recommend this company."

FAQs for mold & toxic material test projects in Harrisburg, PA

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.
