The Radon Bros LLC is committed to excellence in every aspect of our business. We uphold a standard of integrity bound by fairness, honesty, and personal responsibility.

Above all, we are watchful of our customers' interests and make their concerns the basis of our business.

"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. "

When you have mold, making the correct decisions right away is critical. Whether it is mold in your home, school, place of work, or apartment there are many factors to consider. Are you going to be involved in a mold lawsuit? Will you be seeking property damages? Is anyone sick from mold exposure? Will you be seeking medical damages? Will you need expert witnesses? If so, what kind? Do you just want to test to be sure your environment is safe? Do you need post mold remediation testing to ensure a good job was done? These and other factors are questions which need to be answered before any environmental testing starts. It is important to know what your goals are and why your testing. Different goals require different environmental tests, i.e. medical damages and property damages require different environmental tests to prove your case in court. Tests that a common, or inexperienced, mold inspector would not typically use or know to use.

"The mold testing is fine. The mold remediation company is very sketchy. Just buy some air purifiers."

Buying a home can be exciting, momentous, and meaningful. However, it can also be stressful - especially if you're not sure how to gauge the physical condition of a house. That's where the experts at Enviroquest come in. While you focus on the home's style, size, layout, price, and neighborhood, we can take care of evaluating its major systems - like the plumbing, heating, and electrical. Then, we'll provide you with a written report to help you make the best buying decision possible. Making sure you have all the information before you make such a significant decision simply makes sense, and in some cases is the law. Count on Enviroquest to give you the unbiased, professional opinion you need, when you need it.

"Brent was so great to work with! He was straight forward and communicative, going into detail where he needed to, and turned out an incredibly thorough report that my wife and I plan to use as reference for many years to come. I can’t recommend Enviroquest enough to conduct your home inspection."

FAQs for mold & toxic material test projects in Mount Joy, 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.
