Radon Mitigation in Toledo, Ohio
Once a radon test comes back at 4.0 pCi/L or higher, the U.S. EPA recommends an active mitigation system. The standard approach in northwest Ohio is sub-slab depressurization — a sealed PVC pipe pulls soil gas out from beneath the basement slab and vents it above the roofline before it can enter the living space.
How a typical install works
- Site walk. The technician inspects the foundation, sumps, slab penetrations, and existing HVAC layout to size the system.
- Suction point. A core drill cuts a 4-inch hole through the slab. A small pit is excavated underneath to create a depressurization void.
- Pipe routing. Schedule-40 PVC is routed up through the conditioned envelope — typically a closet, mechanical chase, or framed soffit — to the attic or out an exterior wall.
- Fan. An inline radon fan is mounted in unconditioned space (attic or exterior wall). The fan runs continuously.
- Sealing. Visible cracks, the sump cover, and the slab-wall joint are sealed with polyurethane or radon-rated caulk.
- Manometer. A U-tube pressure gauge is installed on the visible riser so the homeowner can confirm the system is running.
- Post-mitigation test. A continuous monitor runs for 24 hours after startup; a confirmation test follows at 30 days. See post-mitigation testing.
System types
Most basement systems are sub-slab depressurization. Homes with a dirt or partial crawlspace need crawlspace mitigation — a sealed vapor barrier with a pipe under the membrane. Houses with both basement and crawlspace get a multi-suction system tied into a single fan.
Materials and warranty
Schedule-40 PVC, EPA-listed radon fans (Festa, RadonAway, AMG), and AARST-rated sealants are standard. Fans are warrantied by the manufacturer for five years. Workmanship is warrantied for one year. The system is designed to bring the home below 4.0 pCi/L; if the post-mitigation test still reads high, the install is adjusted at no additional cost.
Service area
Mitigation is performed across Toledo, all Toledo neighborhoods, Sylvania, Perrysburg, Maumee, Oregon, Holland, Ottawa Hills, Waterville, Whitehouse, Rossford, Northwood, and the surrounding Lucas County area. See locations.
FAQ
How long does a radon mitigation install take?
A standard sub-slab depressurization system on a single-family home in the Toledo area is completed in four to six hours. Crawlspace encapsulation systems run a full day. Multi-foundation homes can take two days.
How loud is a radon fan?
A correctly sized fan installed on an exterior wall or in the attic produces about the same sound level as a refrigerator at the closest interior wall. Inline silencers are available for finished basements where the system runs through living space.
What is the typical mitigation cost in Lucas County?
Most basement sub-slab systems run $1,200 to $2,000. Crawlspace systems typically run $1,800 to $3,500 depending on square footage and access. Final pricing depends on slab type, fan size, and the routing required to vent above the roofline.
Will mitigation work on a stone foundation?
Older homes in Old West End and similar Toledo neighborhoods often have stone or block foundations that leak air at the rim joist. Sealing the perimeter and using a higher-static-pressure fan is usually enough; severely deteriorated foundations may need a multi-suction system.
