"We had our radon fan replaced by Radon Bros in January 2025. From the beginning, the new fan was noticeably louder than the previous one. At that time, the technician advised us that the increased noise was due to the fan being stronger than our prior unit. Over time, the fan became increasingly louder and ultimately stopped working in early December 2025. When a technician returned to replace the fan, we were informed that the fan originally installed was defective and that Radon Bros had stopped using that manufacturer due to known issues. Despite this, we were charged a $99 labor fee for the replacement. We do not understand why we were responsible for this charge when the failure was due to a defective fan that your company was already aware of and no longer installs. We felt we had no choice but to pay the $99 in order to have our radon mitigation system restored and functioning properly."

"This is an UPDATED REVIEW. My original review was posted on 10/16/2020 with a F rating. After that, the company got in contact with my wife and I to offer the opportunity to correct our previous bad experience, they even offered a 10% discount off of the original price quoted. We accepted, made payment and services was performed on 11/19/2020. Christian and James both showed up, James personally apologized for the prior hiccups and assured we’d be satisfied. The Mold Remediation was done on 11/19 and Christian returned the next morning for some additional stain removal. We are satisfied with the service given and are even looking to rehire them to some work they recommended."

"Upon submitting the request for quotes on mold remediation I was contacted by Dave within hours to 1 day. I had a consultation scheduled with Dave within the week. I can not attest to the testing services of All Mold & Basement Services as I had the testing done prior to submitting the quote requests. Dave was very professional and forward with his process. While their process is very similar to others on this site, they go the extra mile and use a dry ice blasting technique to remove and eradicate the mold from all services and even between the joists and flooring which other companies could not guarantee would be done. Because of this process they weren't the lowest quoted price but the end result was the wood looked BRAND NEW. Both my wife and I were astonished. There were some delays in getting started and finished however this was not due to the company but adverse weather. With close to 1,600 sqft needing work and in meeting the agreed upon deadlines some areas appeared to had been missed and were brought up with Dave. He personnaly came out with one member of his crew and the necessary treatment materials and immediately took care of the questionable spots. I can't speak highly enough of Dave and his folks and I would highly recommend this company if you have need of mold remediation work."

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.
