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."

‘Due Diligence, llc’ is a veteran owned/operated professional home inspection company. While not all home inspectors bring the same level of experience to the table, our sole inspector, with over 25 yrs remodeling and 15 yrs forensic failure analysis, brings more than most. We pride ourselves in providing unbiased, thorough inspections and take the time necessary to insure our clients have a full understanding of any/all concerns identified.

"As a local Realtor, I've worked with many inspectors. But since working with Jeffrey, he is now my #1 go-to Inspector on my speed dial! I can confidently refer him to my Clients, knowing they will be getting the best of the best! While working with Jeffrey, I've been blown away by his attention to detail, how knowledgable he is & how he's able to explain even complex issues in layman's terms - for anyone to understand! His inspection report is the most organized home-owners guide, that I'm confident you will reference the whole time you live in your home! With the level of service you receive... you'll be shocked with how affordable his rates are! There are inspectors out there charging a lot more, and you get a lot less than what Jeffrey will do for you! Hire Jeffrey... you won't be disappointed!"

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

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

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.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

Services test for allergens, mold, VOCs, and carbon monoxide levels to ensure a healthy indoor environment.
