"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."

"My experience with Patrick can be summarized as thorough, detailed, and honest from start to finish. From my first phone call with him, it was clear that Patrick truly had my best interest at heart. He explained the entire inspection process, including how long we would be at the home and what he would and would not review during the inspection. Patrick even took the time to pull up the property online while we were on the phone to advise me on his concerns and some additional services to consider before buying the home; no other inspector we called put forth this effort. Upon arriving at the home, Patrick quickly set up shop. On the kitchen counter, he immediately laid out his tools, radon detector, and the snacks he was kind enough to bring for us. From there, we systematically began inspecting each room of the home with Patrick narrating his thoughts aloud. He explained his concerns and safety issues, and he provided many recommendations on fixing and maintaining the home in the future. As a first time homebuyer, Patrick was patient with answering all the questions I had in a clear, understandable manner that left me feeling confident in my ability to care for the home in the future. After the 6-hour inspection, Patrick quickly sent me a 16-page report, all photos he took during our visit, and all city permits on file for the home for me to review. I highly recommend Patrick if you need a building inspector."

"This is my 2nd home mitigating radon through SWAT. Very, very good!"
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.
