Frequently Asked Questions
What is radon?
Radon is a naturally occurring radioactive gas that forms when uranium breaks down in soil and rock. It can enter homes through foundation cracks, sump pits,crawl spaces, and other openings. Because radon is colorless, odorless, and tasteless, testing is the only way to know if your home has elevated levels.
Why is radon dangerous?
Long-term exposure to elevated radon levels increases the risk of lung cancer. In fact, radon is the second leading cause of lung cancer in the United Statesand the leading cause among non-smokers.
Is radon common in Michigan?
Yes. Michigan has many areas with elevated radon levels due to the natural geology of the region. Homes throughout Southeast Michigan, including Oakland County, Macomb County, Wayne County, Livingston County, and Washtenaw County, can experience high radon levels.
Can you see or smell radon?
No. Radon is invisible and odorless. You cannot detect radon without proper testing equipment.
How does radon enter a home?
Radon typically enters through:
- Foundation cracks
- Sump pump pits
- Crawl spaces
- Floor drains
- Utility penetrations
- Gaps around pipes
- Concrete joints
Even tightly sealed or newly built homes can have elevated radon levels.
Can newer homes have radon problems?
Yes. Both new and older homes can have high radon levels. Modern homes are often built more airtight, which can actually trap radon inside more easily.
Can homes without basements have radon?
Absolutely. Homes built on slabs or crawl spaces can still have elevated radon levels and should be tested.
How do I know if my home has radon?
Testing is the only way to know. Professional radon testing provides accurate measurements of radon levels inside your home.
What radon level is considered dangerous?
The EPA recommends taking action if radon levels are 4.0 pCi/L or higher. However, there is no completely safe level of radon exposure, and lower levels can still carry some risk.
How is radon testing performed?
A certified radon professional places specialized testing equipment in the lowest livable area of the home. The test measures radon concentrations over a specific period of time.
How long does a radon test take?
Most professional short-term radon tests take between 48 and 96 hours.
How effective are radon mitigation systems?
Professionally installed mitigation systems can often reduce radon levels by up to 99%.
How often should a home be tested for radon?
Homes should generally be retested every two to five years, or anytime major renovations, additions, or foundation changes occur.
Should I test for radon when buying a home?
Yes. Radon testing is strongly recommended during real estate transactions to help protect buyers and ensure healthy indoor air quality.
What happens if my home tests high for radon?
If elevated radon levels are found, a radon mitigation system can typically reduce radon to safe levels quickly and effectively.
What is a radon mitigation system?
A radon mitigation system is designed to reduce radon gas levels inside a home. The system safely vents radon gas from beneath the foundation to the exterior of the home.
How does a radon mitigation system work?
Most systems use a process called sub-slab depressurization. A specialized fan creates suction beneath the home’s foundation and redirects radon gas safely above the roofline before it enters the living space.
How much does radon mitigation cost in Michigan?
Costs vary depending on the size and design of the home, foundation type, and system complexity. Most residential radon mitigation systems typically range from approximately $1,200 to $2,500.
How long does radon mitigation installation take?
Most radon mitigation systems can be installed in one day.
Will a radon mitigation system damage my home?
No. Professional systems are designed to be minimally invasive while maintaining the appearance and integrity of your home.
Will the radon fan be noisy?
Modern radon fans are designed to operate quietly. In most homes, the fan noise is minimal and often barely noticeable.
Does radon mitigation increase electric bills?
Radon fans use very little electricity. Most homeowners see only a small increase in energy usage.
Can a radon mitigation system be installed in a finished basement?
Yes. Professional mitigation systems can often be installed in finished basements while minimizing visual impact.
Do radon systems require maintenance?
Radon systems require very little maintenance. Periodic inspections and monitoring are recommended to ensure the system continues operating properly.
How long do radon fans last?
Most radon fans last approximately 5 to 10 years depending on usage and environmental conditions.
What happens if the radon fan stops working?
If the fan stops working, radon levels may begin rising again. A professional inspection and fan replacement can restore proper system performance.
Can radon come back after mitigation?
Radon levels can increase again if a mitigation system stops functioning properly. Routine monitoring helps ensure continued protection.
Does radon mitigation improve home value?
A professionally installed mitigation system can help reassure buyers and may improve marketability during a home sale.
Who pays for radon mitigation during a home sale?
This is negotiable between buyers and sellers. In many transactions, sellers agree to install mitigation systems to help complete the sale.
How quickly can radon mitigation be completed before closing?
Many systems can be installed within a few days, helping keep real estate transactions on schedule.
Are your radon technicians certified?
Professional radon contractors should maintain industry certifications and follow EPA and state guidelines for testing and mitigation.
What certifications should a radon contractor have?
Look for certifications from organizations such as:
- NRPP (National Radon Proficiency Program)
- NRSB (National Radon Safety Board)
Do you offer crawl space radon mitigation?
Yes. Crawl space mitigation systems are available and can effectively reduce radon levels in homes with crawl space foundations.
Can you install radon systems in new construction homes?
Yes. Radon-resistant new construction systems can help reduce radon risk in newly built homes.
