Radon is a radioactive gas that seeps into homes from the soil beneath them — and you can’t see it, smell it, or taste it. It’s also the second leading cause of lung cancer in the United States, according to the EPA, and many Michigan homes test above the recommended action level.
Total House Inspection places a continuous radon monitor in your home for 48 hours, then delivers a clear report by email — usually within hours of the test ending. If your levels come back elevated, we’ll walk you through what it means and what to do next.
Don’t wait until it’s too late to protect your loved ones from the serious risks of radon exposure. Contact Total House Inspection today to schedule your radon testing right away. Our friendly and knowledgeable team is here to guide you through the process and provide you with the peace of mind you deserve. Take the first step towards a healthier indoor environment with Total House Inspection and experience the better for yourself.
Radon comes from uranium breaking down in soil and rock, and it collects most in basements and lower levels — which makes it a real concern across Southeast Michigan, where basements are the norm rather than the exception. Newer, well-built homes aren’t exempt: radon enters through foundation cracks, sump pits, and gaps around pipes, regardless of a home’s age or condition.
The EPA recommends action at 4.0 pCi/L (picocuries per liter), with levels between 2.0–4.0 pCi/L also worth addressing. Testing is the only way to know where your home actually stands — visual inspection can’t tell you.
Our inspectors are InterNACHI Certified and hold CPI (Certified Professional Inspector) and Residential Property Inspector credentials, backed by continuous radon monitors that meet EPA measurement protocols. Radon testing can be scheduled on its own or bundled with a full home inspection — a common and recommended step whether you’re buying or selling.
An elevated result isn’t a crisis — it’s a fixable problem. Homes with high radon are typically brought below the action level with a mitigation system that vents the gas safely outside, usually installed by a qualified mitigation contractor. Your report will lay out your specific numbers and recommended next steps so you know exactly where things stand before you make any decisions.
See exactly what you’ll receive: professional radon test results, clearly measured radon levels, and a plain-language breakdown of what the readings mean for your home.
Radon testing is a small investment next to the cost of ignoring the problem, untreated high radon carries a real long-term health risk, and a mitigation system installed proactively is far simpler than dealing with a failed real estate transaction or a health scare down the road. For the peace of mind it provides, radon testing is well worth the cost.

Radon is a naturally occurring radioactive gas produced by the breakdown of uranium in soil, rock, and water. It's colorless, odorless, and tasteless, so it can't be detected without testing. Long-term exposure is the second leading cause of lung cancer in the United States, which is why testing your home is so important.
Radon seeps up from the soil and enters through cracks in the foundation, gaps around pipes, sump pits, crawl spaces, and openings in floors and walls. Because it comes from the ground, even newer, well-built homes in Michigan can have elevated levels.
Radon testing is $275 on its own, or $205 when bundled with a home inspection, a $70 savings. Contact us or schedule online for a quote specific to your home.

The U.S. EPA recommends taking action to reduce radon if levels are at or above 4.0 pCi/L (picocuries per liter). Levels between 2.0 and 4.0 pCi/L may also be worth mitigating. If your test comes back high, we'll explain your results and recommended next steps.
Yes. Many Michigan counties fall into elevated EPA radon zones, and a significant share of Michigan homes have radon above the EPA action level. Testing is the only way to know your home's actual level.
