Radon Mitigation in Cheney, WA

Cheney is built where two landscapes meet: deep wind-blown loess to the north and flood-scoured basalt scabland to the south, with the rail line running roughly along the divide. State test data put the town's census tracts between about one in five and nearly two in five tests at or above the EPA action level, below the county average but far from rare.

How it works in Cheney

1. STEP 1
   Test

   A 48-hour continuous monitor in your lowest living level, under closed-house conditions. Report the same day it comes out.

2. STEP 2
   Look and quote

   We check the foundation, run a suction test and plan the pipe route for Cheney winters. You get a fixed price in writing.

3. STEP 3
   Install

   Most systems take one day: suction point, sealing, fan, manometer and the electrical permit.

4. STEP 4
   Re-test

   A post-mitigation test at least 24 hours after the fan starts shows the new number. The guarantee is below 4.0 pCi/L.

Radon mitigation cost in Cheney

Inside city limits a radon fan runs on power from the city-owned Cheney Light Department, which serves about 5,600 customers and charges a flat 7.45¢ per kWh in 2026. Homes outside town may be on Avista or Inland Power instead, depending on the address. South of the tracks, where basalt reaches the surface, a pressure-field test before the quote shows how far suction will carry.

A 20-watt fan costs about a third of that, a 90-watt fan half again as much.

Two kinds of ground under Cheney

Cheney straddles the edge of an Ice Age flood channel. North of town rise rolling hills of deep loess, wind-blown silt that the Missoula floods never reached. To the south the floods scoured the land into channeled scablands of exposed basalt, pine groves, ponds and wetlands. The railroad roughly follows the line between the two, and most of the town has historically been built on the farmland side.

In the low ground around Meadow Lake and along Minnie Creek, the floods stripped most of the silt and left gravel instead. Just outside town, at Turnbull National Wildlife Refuge, upland soil is only centimeters thick over the basalt. The U.S. Geological Survey notes that this basalt is generally low in uranium; across the region, most of the uranium sits in the flood, lake and wind-blown sediment on top, carried in from more uranium-rich rock in northeast Washington and north Idaho.

The state's test data put Cheney below the county, but not low. In the four census tracts within ZIP 99004, between 18.8% and 38.5% of reported tests came in at or above 4.0 pCi/L, against 47.0% for Spokane County. Even the lowest tract works out to nearly one test in five. Tract figures cannot sort out individual streets, let alone houses.
