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!"

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.

Radon Detection and Reduction questions, answered by experts

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

To determine whether you have radon in your home, you must run a test. Radon gas has no odor or color, so you won’t notice a concentration of radon. You could purchase a DIY test at a local hardware store, but it may not deliver completely trustworthy results. The best way to test and receive accurate results is to hire a local radon detection specialist.

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.

In most states, radon testing companies don’t need to be licensed or certified by the state, but the companies that analyze the test results and develop radon mitigation protocols do. You should choose a radon testing company that suits your needs, but before hiring a mitigation specialist, check our state licensing tool to make sure the company is properly certified.
