How we got these numbers
National benchmark costs from RSMeans, Angi, Fixr, and HomeGuide are adjusted for Oregon using two federal datasets: the Bureau of Economic Analysis Regional Price Parity (RPP) index and the Bureau of Labor Statistics (BLS) Occupational Employment and Wage Statistics. Oregon's RPP is 1.0 (national baseline = 100) and its BLS labor adjustment factor is 1.10. Higher RPP means goods and services cost more relative to the national average; the BLS factor scales contractor labor rates to local wage levels. We blend these two adjustments, weighted 40% RPP, 60% BLS labor, to produce the ranges shown above.
adjusted_cost = national_benchmark × (0.4 × RPP/100 + 0.6 × bls_labor_adj)
RPP(Oregon) = 1.0 · BLS adj = 1.10

TOOLS TO RENT OR BUY
Hammer drill and core bit
To open the slab for suction
Build sequence
- 1
Test to confirm radon levels and locate the best suction point.
COMMON MISTAKE
Installing a system without testing first, or to the wrong target level.
- 2
Core a hole in the slab and excavate a small suction pit beneath it.
- 3
Run the vent pipe up through the house and out above the roofline.
COMMON MISTAKE
Terminating the exhaust too low or near a window lets radon re-enter.
- 4
Install the fan in an attic or exterior run, never in the living space.
COMMON MISTAKE
Mounting the fan below living areas can pressurize radon into the home.
- 5
Seal slab cracks and the sump, then re-test after the system runs.
