Radon Mitigation
NRPP-certified mitigation and trade coordination for Michigan properties. Sandison evaluates the complete system, explains the evidence, and coordinates plumbing, mechanical, or electrical requirements when they overlap.
The short answer
Start with the complete system and the evidence
Radon mitigation starts with the test record and the home's foundation, then uses a system designed for those conditions. Sandison evaluates suction locations, pipe and fan placement, electrical supply, and the follow-up testing needed to check performance.
What Sandison evaluates
A practical path from testing to the right mitigation system
- Clear diagnostic process
- Licensed multi-trade coordination
- Repair and replacement options
- Residential and commercial support

What should a radon mitigation system look like?
Sandison walks through a professional radon mitigation installation in a Michigan home, connecting the visible pipe and fan to testing, foundation conditions, system routing, electrical coordination, and post-installation verification.
- How the foundation and test results inform the system design
- What to look for in suction piping, the fan, manometer, and discharge route
- Why sealing, electrical coordination, labeling, and service access matter
- Why a post-mitigation test—not appearance alone—verifies performance
Important: The video shows real workmanship and system components, but it cannot diagnose another home. Foundation conditions, testing, system design, and post-mitigation measurement remain property-specific.

Common questions
What property owners ask
Can I tell whether a home has a radon problem by looking at it?
Radon cannot be identified by smell or appearance. A properly conducted test provides the information needed to evaluate mitigation.
Why might similar houses need different radon systems?
Slab sections, crawl spaces, additions, sumps, and how air moves beneath the foundation affect system design. Those conditions determine the appropriate suction points and routing.
How do I know whether mitigation has lowered the radon level?
An appropriate post-mitigation radon test checks the result. The fan and operating indicator are useful parts of system monitoring, but their appearance alone does not establish the radon level.
