Radon is a silent killer. It's a colorless, odorless radioactive gas which naturally occurs in the ground below us, and gets pulled into our homes, schools and businesses. Why should you worry about something you can't see or smell? Radon is the second-leading cause of lung cancer in the United States, with the US Surgeon General and the EPA estimating 20,000 Americans die every year due to radon exposure. Lifetime Radon Solutions is proud to be a locally owned and operated business that has been in operation since 1993! With years of experience and unmatched expertise we can help with any and all of your Radon testing and abatement needs. Get in touch today!

"Greg was absolutely great----arrived early, incredibly professional, and found several things I suspect a lot of other competitors would have missed which were very much appreciated. The inspection went fast, but nothing was missed. This guy obviously knows his stuff, and we've already recommended him to a neighbor considering selling and buying a new house too. Again, great guy, highly professional and knowledgeable, and reasonably priced. A+++ Scott Hoffman"

Radon Detection and Reduction questions, answered by experts

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

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

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.

It is possible to test for radon yourself using DIY radon test kits, but these at-home test kits should never be a replacement for professional radon testing. DIY test kits can provide some information about radon exposure in your house, but your indoor temperature and humidity can affect the results, as can improper usage of the test kit. You could save yourself some money by hiring a radon professional to begin with, and when it comes to your family’s safety, hiring an experienced professional to do the testing is usually the best option.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.
