Radon Mitigation Cost in Virginia (Roanoke Area)
What does radon mitigation cost in Virginia? The Virginia Department of Health (VDH) publishes typical ranges, and EPA explains what pushes a price up or down. Here's what those official sources say, so you can judge the quotes you get for a Roanoke-area home.
About these numbers: they're the ranges VDH publishes, not our prices and not a quote. We don't set prices. VDH doesn't date these figures, and costs change, so use them as a reference point and get written quotes from certified mitigators.
Typical radon mitigation cost in Virginia
| Item | VDH's published range | Source |
|---|---|---|
| Typical sub-slab depressurization system | $800–$1,200 | VDH Testing & Mitigation |
| Crawlspaces, or homes with several sections that need mitigating | $2,000 or more | VDH Testing & Mitigation |
| Professionally installed radon reduction system (overall) | Typically $800–$2,500 | VDH FAQ |
| Professional radon test | Usually $100–$200, depending on the device | VDH Testing & Mitigation |
| Do-it-yourself test kit | Short-term $10–$15; long-term $25–$35 | VDH FAQ |
EPA doesn't publish a dollar figure. It says most homes can be fixed for about the same cost as other common home repairs, and that your cost depends on the size and design of your home and which reduction methods are needed (EPA). VDH has also offered a limited supply of short-term test kits for a $4 shipping fee; check the VDH radon page for current availability.
The action level: when mitigation is worth paying for
EPA recommends fixing your home if a long-term test, or the average of two short-term tests, shows 4 pCi/L or higher, and says to consider fixing between 2 and 4 pCi/L. VDH says most homes can be brought down to 2 pCi/L or below. Roanoke city, Roanoke County, Salem and Botetourt County are all EPA Zone 1; see radon levels in Roanoke for the local test data.
What drives the price
VDH says the cost depends on how your home was built and how big the radon problem is. EPA adds home size, design and the methods needed. For a specific house, quotes usually turn on:
- Foundation type. A single basement or slab is the simplest case. Crawlspace homes usually get a sealed plastic membrane with suction under it, which EPA calls the most effective approach for crawlspaces. VDH's range for crawlspaces and multi-section homes starts at $2,000.
- What's under the slab. EPA notes sub-slab suction works best when air moves easily through the material under the slab. Tighter soil can mean more suction points.
- Pipe and fan route. EPA's guidance keeps the fan out of living space and vents the exhaust above the roof, so an interior route to the attic and an exterior route up the wall price differently.
- Sump pits and drain tile, which can serve as suction points but need an airtight cover.
- Your starting level. Very high readings can need a stronger fan or extra suction points.
- Sealing, electrical work and permits. EPA tells homeowners to ask for the total cost including all taxes and permit fees.
Running costs after installation
- Electricity: EPA says fan systems run continuously and slightly increase your electric bill, and most systems cause some loss of heated or cooled air.
- Fan replacement: EPA notes fans may last five years or more (manufacturer warranties tend not to exceed five years) and then may need repair or replacement. Ask for an estimate up front.
- Retesting: EPA recommends a test within 30 days of installation and again at least every two years. A DIY kit costs what's listed above.
Getting a fair quote
- Get estimates from more than one qualified mitigator, as EPA recommends.
- Confirm NRPP or NRSB certification (required by Va. Code § 32.1-229.01) and a Virginia contractor license with the RMC specialty on DPOR License Lookup.
- Ask for a written contract with the total price, the method and number of suction points, where the pipe and fan go, what's guaranteed, and whether a post-mitigation test is included.
- Compare what you get for the money: EPA notes a cheaper system can cost more to operate and maintain.
