Radon mitigation pricing in the Quad Cities is driven by the foundation, not the radon number. A single-suction-point system on an accessible basement sits at the bottom of the range; stone or block foundations common in older Davenport neighborhoods, crawlspaces needing a sealed membrane, or a second suction point push toward the top. Iowa's deep frost line matters too — exterior pipe runs have to be detailed against freeze-thaw, and an attic-routed system costs more in labor but hides the pipe and protects it from Iowa winters. Every quote should be written, should name the number of suction points, and should include the post-mitigation retest.

What moves the price

The quote is mostly a function of four things: foundation type (open basement vs crawlspace vs slab-on-grade), number of suction points the soil communication test says you need, pipe routing (interior/attic runs cost more labor than an exterior run but are protected and invisible), and fan sizing. The radon level itself barely moves the price — a 20 pCi/L house and a 6 pCi/L house usually get the same system.

Two rules protect you regardless of price: get the quote in writing with the suction-point count named, and make sure it includes the post-mitigation retest. A cheap system that was never re-tested is not a bargain — it is an unverified one.

Davenport Radon Mitigation Cost — FAQ

Why do quotes for the same house differ so much?

Usually one contractor is bidding a single suction point and another is bidding two, or one is routing through the attic and the other down the exterior wall. Ask each bidder to name the suction-point count and route — the quotes usually reconcile once you compare like for like.

Is a more expensive system better?

Not inherently. The right system is the one matched to your foundation's soil communication — an oversized fan wastes electricity and can pull conditioned air; an undersized one never gets the house below the action level. Judge quotes on the diagnostic work behind them, not the sticker.

Does homeowners insurance or any program cover it?

Standard homeowners policies treat radon mitigation as a home improvement, not a covered loss. Some assistance has existed at times through state or county health programs — worth one call to the Scott County health department before paying out of pocket.

What does running the system cost per year?

The fan draws roughly what a low-wattage light bulb does — typically a few dollars a month in electricity, plus eventual fan replacement every five to ten years. There is no filter, refill, or service contract.
