Steve is the sole proprietor of True Check and is available seven days a week for your service. I accept check, cash and credit cards for payment. Book an appointment through Angie's List and receive 10% off. And $ 25 dollars for referrals that turn into jobs.

"Steve is thorough and gave us an excellent, detailed inspection on a home in Colorado Springs. He saved us a ton of money by locating serious issues with that home, and we have hired him for another inspection on a different home. He is very knowledgeable, nice, and easy to work with. We will not be able to be present for the second inspection, but I'm confident in his work and recommendations. We had inspection, sewer scope, and radon."

Radon Detection and Reduction questions, answered by experts

Yes, if high levels are detected, professionals can provide solutions for radon reduction.

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. 

A radon test has no effect on humans—only the radon in the air does. The test does not redistribute the radon that is already present so yes, it’s safe to be around the testing kit even if it isn’t safe to be in the room itself. The test absorbs and measures the radon, but doesn't absorb enough of it to make the room any safer.

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

Costs depend on property size, test types, and additional services like mold sampling.
