"Overall; it went well until the first driving rain which allowed water into the system. Had asked them about the pipe allowing water in and how that would affect the fan. They told me they warrantied their work and to not worry. They also said a drain hose would not allow water to bother the fan. For two weeks my readings had dropped to below 2 which is half the national average for needing the remediation (called them and said thank you). Then the rain hit and it has sounded sickly ever since without a break. For the first couple months; it sounded like someone threw in ball bearings to that fan. But since has just sounded sickly. Also have a radon of around 20; which is very unsatisfactory. I called them and told them the meter measuring inches of water equalized and I'm calling to have them come over to fix it. I asked if they had put enough sealant around the pipes. They said yes; and I looked and could find no problems with penetrations in floor being bad. He never came back over. I called several weeks later and left a message. No call back. Called a third time and no call back. I called the state radiation protection supervisor and she tried to get a hold of them. First they said they had the flu and would get back to her. They never called me. My advice to anyone dealing with radiation mitigation; would be not to use these people. I would also suggest they not move to Western Pennsylvania for two reasons. One is the pollution like radon which is abundant. Unless you want your kids to have lung cancer and other problems. They will never mention it to you before you move here. Most never find out. My dog had lung cancer after a few years; I have lung problems after a few years... my neighbor died of lung cancer a few years ago... this is a real issue people. Also, the state does not have authority to do much in this state apparently. I've also noticed many discrepancies with the state in other area's but that is not what we are talking about today. Just choose wisely. I've not mitigated my radon; nor have I had any real recourse; which is normal in this state. As is the level of experience in Western Pa. As it relates to national levels. Oh, if you do get sick here in western pa; you will likely die from the hospitals and staff here; though Pittsburgh has some good doctors; the rest of western pa is like going back 50 years in time; though they do well hiding that fact on outcomes. So your radon journey will be bad form cradle to grave in Western Pa. I've lost my time and money messing with this mitigation service. Found that the drain was installed incorrectly and made a p-trap just below the fan. This is the source of the problem ( I believe). Will have to be done over. Perhaps by myself when it cools down."

Radon detection and reduction services FAQs

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.

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.

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.
