About Us

Knowledgeable Home Inspector Experts

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

Someone that can provide radon gas, well water, and termite testing.  A thorough inspection you expect and a report you can rely on to make a confident decision quickly. 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.

As an Indiana-licensed Certified Professional Inspector® trained by InterNACHI—the International Association of Certified Home Inspectors—and with 20 years’ experience as a general contractor.  Let my experience help spot problems with materials, installation, and workmanship that other inspectors might miss.

I understand first-hand how stressful a real estate transaction can be. My experience as a former licensed loan officer gives me the knowledge needed to help you close transactions faster. So, whether you’re buying or building a new home, or selling the one you’re in, let OnTheMark LLC give you the peace of mind you deserve so that you can make the right choice for your family’s future.
