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."

Most people get frustrated when trying to communicate with a contractor. At Joyland Roofing, we set a new standard for roofers by corresponding quickly and often from start to finish. You’ll be provided with a clear roof analysis and estimate so you’re confident in our solution. Residential & Commercial roof replacements & repairs. Shingles, metal, rubber. Skylights, sun tunnels, gutters, windows, siding, chimney repairs. Serving Lancaster, Dauphin, Lebanon, Berks, York, Chester, Cumberland, and Montgomery Counties. We are certified by leading roof material manufacturers: GAF MasterElite, MuleHide, and Roofing Products International. We can offer industry-leading warranties and guarantees, & your roof will be installed using manufacturer recommended practices!

"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!"

Radon Reduction Service. 2015 Super Service Award. Serving the South Central PA region since 1991. We have installed over 10,000 efficient, quality and nice looking radon reduction systems in the area.

"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."

Radon Detection and Reduction questions, answered by experts

Radon testing costs around $450 on average, but you could pay between $150 and $800 for testing, depending on a few factors. The size of your house is one of the most significant cost factors, as your radon professional will have to set up additional tests for homes with larger footprints. The type of test can also have an impact on the cost. Finally, some radon testing companies will include a recommended protocol for radon mitigation, while others might charge $50 to $100 extra.

Costs for radon detection services typically range from $150 to $250, depending on the testing method and whether a professional assessment is required.

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.

Since radon typically comes out of the soil, it is most commonly found in the lower levels of a home. In houses with basements, that's a common location for radon. Homes built directly on the ground may have radon on the ground floors. Radon can be found on the upper floors of the home, but often in lower concentrations than in lower levels.
