  A home is the biggest purchase you’ll ever make, so it’s important to have a fantastic home inspector.

As your Chicagoland home inspector, let's make sure you understand the home inspection cost and value of a home inspection and radon testing for radon gas.  I am very competitively priced and will include radon testing in your basement at time of inspection for as little as $100.

Although radon is a naturally occurring gas in our environment, it is also the second leading cause of lung cancer deaths in the U.S., according to the Surgeon General. Nearly one out of every 15 homes is estimated to have elevated radon levels.

The Surgeon General and the Environmental Protection Agency recommend testing all houses. Millions of Americans have already had their homes tested for radon, and you should, too. I promise fast turnaround time on laboratory results.

The Facts About Radon Gas - It's Deadly.
