Radon System Repair Services
We’re a one-stop shop for anything radon. Have an existing radon system you suspect isn’t working or needs some attention? Haven’t checked up on your system in years? We’re happy to take a look.
Radon Fan Replacement
Radon fans typically have a 5 year warranty from their manufacturer. The average life we see for a radon fan in a properly designed system is 5-15 years. We keep all fans in stock and can service any radon system from any installer.
Sump Pit Capping
Every sump pit should be capped when a radon reduction system is installed. There are NO EXCEPTIONS to this rule! Too often, we come across radon systems with a wide open sump pit, no sump cover in sight. We install custom built on site sump covers unique to each job. A clean look that functions as well
Radon System Alarm Installation
Radon systems typically do not come with an alarm. There should be a manometer, or “U-Tube” with red or blue liquid installed on the suction pipe to indicate restriction or system failure. However, sometimes the contractor may not have installed one.
Audible alarms and manometers are available for install to indicate radon system function and alert of any failure.
Additionally, sump pump alarms can be added to a system with a sealed sump cap. It can be difficult to watch water levels with a radon mitigation system, so installing a water sensor offers peace of mind.
Radon Pipe Replacement
Whether the installing contractor simply went cheap and didn’t finish the job, or the weather had other plans for your system, a full exhaust system is important. All radon systems should exhaust the gas above the gutter line, or at least 20 feet above the ground. Systems that terminate below that line carry the potential for “re-entrainment,” or the gas re-entering the home. Additionally, the pipe must discharge 2 feet above any opening within 10 feet – such as a window or door.
We can complete a partial system or re-pipe a system – if needed – to ensure proper system performance and function.

Michigan Radon FAQ
What is radon and why is it dangerous?
Radon is a naturally occurring radioactive gas that comes from the breakdown of uranium in soil, rock, and water. It’s invisible, odorless, and tasteless—making it impossible to detect without specialized testing. Long-term exposure to high levels of radon is the second leading cause of lung cancer in the United States.
How do I know if my home has radon?
The only way to know if your home has radon is to test for it. Even if your neighbor’s home tested low, yours could still have elevated levels. At SM Radon Pro, we offer professional radon testing using continuous monitors for accurate results.
What level of radon is considered unsafe?
The EPA recommends taking action if your radon levels are 4.0 picocuries per liter (pCi/L) or higher. However, even levels between 2.0 and 4.0 pCi/L can pose some risk, especially with long-term exposure.
Is it expensive to fix my radon system?
Radon system repair costs depend on the extent of damage. Most radon system repairs are less than $500.
How long does it take to repair a radon mitigation system?
Many repairs can be made quickly. Replacing a radon fan takes less than one hour, while replacing a sump cap can take a few hours depending on complexity.
Is the radon mitigation system noisy or visible?
Our systems are designed to be as quiet and unobtrusive as possible. The fan is usually installed in an attic or outside the home, and piping is routed discreetly. We prioritize function and aesthetics.
How much does radon mitigation cost?
Pricing depends on the size of your home, foundation type, and radon levels. Most systems range from $900 to $1,500. We offer free estimates and transparent pricing with no hidden fees.
Do I need to retest my home after mitigation?
Yes. We always perform a post-mitigation test to confirm your system is working and that radon levels are reduced below the EPA guideline. We also recommend re-testing every 2 years or if major home renovations occur.
Are you certified and insured?
Absolutely. SM Radon Pro is NRPP-certified, NRSB-certified, AARST-certified fully insured, and follows all EPA and state guidelines for radon testing and mitigation.
