If you’ve discovered radon lurking in your Iowa home, you’re not alone. This invisible, odorless gas is a big deal here—Iowa has some of the highest radon levels in the country, with the Iowa Department of Health and Human Services estimating that 7 out of 10 homes exceed safe levels. Installing a radon mitigation system is the smartest way to protect your family, but how much will it set you back in the Hawkeye State? And what’s the difference between an internal system venting through the roof versus an external one exiting through the wall? At Adios Radon, we’re here to help you figure that out. Let’s break down the costs and options.
What’s the Average Cost in Iowa?
In Iowa, the cost of a radon mitigation system typically ranges from $1,800 to $2,500, with most homeowners landing around $2,000. That’s a bit higher than the national average of $800 to $2,000, and there’s a reason for it—Iowa’s radon problem is intense, and homes here often need robust solutions. Factors like your home’s size, foundation type, and your radon levels play a role in the final price. At Adios Radon, we’ve seen it all, and we tailor every job to your specific needs.

Internal Systems: Venting Through the Roof
Imagine a pipe starting under your foundation, weaving up through your home—maybe tucked in a closet or along a wall—and popping out through the roof. A fan pulls the radon up and vents it out above your living space. That’s an internal mitigation system, and it’s a common pick for Iowa homeowners who want a discreet setup.
In Iowa, expect to pay between $2,300 and $2,800 for this option with Adios Radon. Why the premium? Routing a pipe through your house and penetrating the roof takes extra labor and materials—think weatherproof flashing and longer pipe runs. Newer homes with passive radon systems already in place will see much lower costs, since we can “activate” what’s already there. The upside? No pipes cluttering up your exterior, and the fan’s hum is often less noticeable indoors. The downside? Installation is trickier, and therefore more expensive. Still, it’s a sleek solution for keeping radon at bay.
External Systems: Out Through the Wall
Now picture this: a pipe starts under your foundation and shoots straight out through an exterior wall near ground level, with a fan venting the radon outside. That’s an external system—simple, efficient, and a little easier on the wallet. In Iowa, Adios Radon typically installs these for $1,800 to $2,200.
The savings come from less piping and a quicker setup—no need to navigate multiple floors or cut through a roof. If your home’s layout allows it, this can b done in a day. Maintenance is a snap too; the fan’s right there at ground level. But there’s a catch—you’ll see that pipe and fan outside, which might not thrill everyone. And if it’s near a window or patio, you might catch a faint hum. For many Iowans, though, the lower cost and simplicity make it a winner.
Internal vs. External: Iowa’s Cost Breakdown
So, how do these stack up in Iowa? Here’s the quick scoop:
The choice often hinges on your budget and how much you care about that
exterior vibe. In Iowa’s radon-heavy zones—like Iowa City, Des Moines, or
Cedar Rapids—both get the job done, and Adios Radon customizes either to
fit your home.
