"Jim Shuster was prompt, professional, extremely knowledgeable ... and very pleasant to work with! The initial response to my inquiry was quick, as was all subsequent communication. I was so impressed with the overall Radon Testing experience that I also contracted with Jim to perform an Air Quality Test and Mold Inspection at my residence. I do not think that I could have received a better reference for my job(s) than Premier Inspections Plus. Thank you."

"The drop down box would not let me select Radon Testing. Being that there is a high amount of radon in my area, even in my neighborhood, I had my house tested. They were very professional and explained what they were doing and what they were looking for. Plus they showed up when they said they would, and didn't give me a 6 hour window like some companies. I highly recommend."

"The Buyer's Inspector was extremely thorough. I have heard it said that he is the "pit bull" of home inspectors. He left radon detection equipment behind for over 50 hours. He offered additional water testing at my request. He has provided me with a itemization of all things good, marginal, bad, dangerous of every aspect of my house. He cross referenced these comments with pictures and suggestions. He seemed highly knowledgeable. It will be easy for electrician, plumbers, chimney sweeps, etc. to understand and locate the problem areas in the home. But beware when you schedule: My inspection lasted 6 hours!"

"I had a little issue in my attic and went searching on Angie's List for a contractor....I was notified by Nathan from ASD WATERWORKS. He came out here the next day and gave me a free estimate as to what needed to be done and how much it would cost...We agreed on a figure and set up an appointment to have it resolved... The technicians showed up and were very friendly and professional....They laid down floor covering so that they wouldn't track anything in on the floor and sealed off the room leading to the attic....The process was performed in a timely manner and they cleaned everything up behind themselves. Very impressive....I would highly recommend the company for any problem that you may have and also would use them again if necessary......Thanks ASD WATERWORKS."

If radon is present in your home, you can expect to pay around $1,000 for a radon mitigation system or between $780 and $1,250 in most cases. The exact price will depend on the severity of the radon leak, home size, and the protocol the radon specialist develops to remove radon from your home and keep it out. Your foundation type will also affect your radon mitigation system cost, as unfinished basements will cost about $4,600 to seal and ventilate, while crawl spaces without a foundation slab may need extra encapsulation, costing $1,500 to $15,000.
You can buy DIY radon test kits from a home improvement store and conduct radon testing, but these tests are often inaccurate. No matter the result, you should supplement DIY testing with professional radon detection and analysis. DIYers only have access to passive radon tests, which aren’t as reliable as active tests that professionals use. Plus, it’s very easy for DIYers to make mistakes during testing, leading to inaccurate results. If you’re moving into a new home, have concerns about radon, or are due for an updated test, hire a professional.
Radon testing costs depend on whether you hire a professional radon inspector or DIY test. You can expect to pay $150 to $800 to hire a local radon inspector, and home-testing kits range in price from $15 to $250 from home improvement stores. However, it’s best to trust a professional inspector with this task to ensure accurate results. Plus, if you have radon in your home, your testing company can develop a mitigation protocol to keep you and your family safe from the dangerous gas, so it’s well worth the money to hire a professional.
Yes, radon testing is absolutely necessary if you suspect the presence of this hazardous gas, and the Environmental Protection Agency (EPA) recommends testing for all homes in the country. Radon is a pervasive natural gas that can leak through your home’s foundation and seep into the living areas. Unfortunately, the gas is highly carcinogenic and is the second leading cause of lung cancer. Radon testing is crucial for keeping you and your family safe from harm, so hire a radon mitigation specialist to test your home if you suspect its presence in your home.
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.
