How much does radon mitigation cost in Huntsville, Alabama?
The EPA says fixing a radon problem typically costs about the same as other common home repairs, such as painting the house or replacing a water heater. The exact price depends on your home. This page explains what changes the number and how to compare quotes. Tell us about your home and we will connect you with an independent contractor for a firm price.
What changes the price
- Foundation type. Slab, basement and crawlspace homes use different methods. See our crawlspace guide.
- Size and layout. Some homes need more than one suction point, especially where the foundation is divided into separate sections.
- Pipe route. Running the pipe inside the house versus outside the wall, and how far it has to go, affects labor and materials.
- Fan and electrical. The fan needs power, and the fan size depends on how easily air moves under the foundation.
- Sealing and extras. Sump pits, floor drains and large cracks may need sealing, and you may want a finished look on the pipe.
- Warning device. A gauge or alarm that shows the fan is running should be part of the system.
What about a dollar range?
An older EPA guide for home buyers and sellers gave a range of about $800 to $2,500 for a typical system. That figure is dated and prices have changed, so treat it only as a rough floor and do not rely on it. A written quote after the contractor looks at your home is the only reliable number.
How to compare quotes
- Get more than one estimate, as the EPA suggests.
- Ask for the inspection before the estimate, so the price reflects your actual home.
- Ask what is included: pipe, fan, warning device, sealing, electrical and a retest.
- Ask about certification (NRPP or NRSB), insurance and bonding, the written guarantee, and whether the warranty transfers if you sell.
The lowest price is not always the best one. See what is included before you choose.
Costs after installation
The fan runs all the time and uses some electricity. Fans commonly last five years or more, and warranties are rarely longer than five years. The EPA recommends retesting at least every two years. See the radon testing guide.
Radon cost questions
Is radon mitigation expensive?
The EPA says it typically costs about the same as other common home repairs. The price depends on your foundation, layout and pipe route.
Why do quotes differ so much?
Quotes can differ in what is included, how many suction points are used and how the pipe is routed. Ask each contractor to list what the price covers.
Is there a free estimate?
Many contractors give estimates at no charge, but policies vary. Ask before you schedule.
Does a crawlspace cost more?
It can, because sealing a membrane over the soil adds work. A contractor can price your crawlspace after an inspection.
Do I need to retest after the fix?
Yes. Test at least 24 hours after the fan is running, and retest every two years.
