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!

"They were prompt, polite and did quality work."

An examination of a real estate property's condition, usually performed in connection with the property's sale. A qualified home inspector can assess the condition of a property's roof, foundation, heating and cooling systems, plumbing, electrical work, water and sewage, and some fire and safety issues. In addition, the home inspector will look for evidence of insect, water or fire damage or any other issue that may affect the value of the property.

"The inspection was very thorough."

Radon Detection and Reduction questions, answered by experts

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

Mold, VOCs, radon, carbon monoxide, and particulate matter are typically measured.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

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. 

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