"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."

"Second time we've worked with Joyland on a full roof replacement - couldn't be more pleased! The process was handled professionally and with great communication. Ross began with an in-depth meeting to REALLY listen to what we wanted evaluated and our time constraints. He did a great job answering ALL our questions, examining our roof from the inside as well so there would be no surprises. He even identified chimney work for us to be aware of to get repaired. We had no idea it needed work. A crew was on site within DAYS to start and 2.5 days later, our new roof was COMPLETE. The workers were great and left the property spotless at the end of each day. Conrad - project manager - stayed 100% on top of the daily progress, keeping us informed at all times, even with some rain issues to work around. Taylor in the office was very efficient with all billing and contacts. Another roofer wanted over 75% paid BEFORE any work was done - Joyland had very reasonable terms! MANY THANKS - great job!"

"Greg , the owner has horrible customer service, they don’t stand behind their work. I had a leak and called him on November 30 of 2022, one of his guys came out told us they will be back to fix the window. Never heard from them again. On September 26, 2023 I called them because they didn’t do anything. Of course they’re not taking any blame, when I called him out on it, he hung up on me. I would not recommend this company. The owner is very angry and combative."

"The company installed a radon mitigation system in my house, reducing the level from 300 to .4. They obviously did superb work, and did it promptly at reasonable cost (much lower than the statewide company I got a quote from). Then afterward they provided outstanding customer service by promptly responding to my request to replace the original powerful fan with a quieter fan. Tuan obviously cared about my satisfaction as a customer. My experience is that this company is extremely competent, professional and trustworthy, and I give them my highest recommendation."

"Install done in 2023 and parts was under warranty. 2 years later it breaks and the company wants to charge to fix it. Product under warranty mean no charge to home owner. Not a reliable company. "

FAQs for radon gas testing projects in Mount Joy, PA

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
