Why We Do Not List Prices
Radon systems range from a straightforward single suction point in a basement slab to multiple suction points, sealed crawl spaces and complex layouts. A number published without seeing the house would be a guess, so we leave pricing to the independent companies that inspect your property.
What Changes the Scope of a Job
Foundation type
Basement slab, slab on grade, crawl space and block walls each need different approaches, and a house may combine several.
Your radon level
A higher starting level may call for a stronger fan or additional suction points.
Sub-slab conditions
Gravel or soil under the slab that moves air easily is simpler than dense, clay-heavy or compacted material that limits how far suction reaches.
House layout
Additions, split levels and multiple foundation sections can each need their own suction point.
Pipe route
A pipe through an interior closet is different from an exterior run. Finished spaces, tight ceilings and finished basements change the work.
Fan location and vent exit
Attic, garage or exterior fan locations and where the pipe exits the roof or wall affect materials and labor.
Sealing needs
Sump pits, cracks, floor drains, control joints and block walls all need sealing, and some homes have more entry points than others.
Crawl space liner
A crawl space may need a sealed liner and drainage attention in addition to suction.
Finish work
Painting, boxing in a pipe, or running it inside a wall for appearance changes the scope.
How to Compare Proposals
Make sure each proposal covers the same ground:
- Credential. Is the installer credentialed in Iowa for radon mitigation?
- Diagnosis. Did the company inspect the house and explain where suction will go and why?
- System description. Number of suction points, fan type, pipe route, vent location and monitoring gauge.
- Sealing. What will be sealed, including the sump pit.
- Performance. What level does the company expect to reach and how will it be confirmed?
- Follow-up test. Is a post-installation test included and who performs it?
- Warranty. What does it cover, for how long and are fans included?
- Electrical and finish. Who handles any wiring and what finish work is included?
Things That Do Not Belong in a Radon Quote
- A guarantee of exactly zero radon
- A promise that the system never needs maintenance
- Pressure to buy an add-on that is not tied to a measured problem
- A refusal to share credentials or proof of insurance
Ongoing Costs to Ask About
A radon fan runs continuously and uses a small amount of electricity. Fans eventually wear out, and a company should tell you the fan's warranty and the typical service life. Retesting after renovations and at regular intervals is part of owning a system. Ask about all of these before you decide.
Special Situations That Change a Job
Some houses simply take more planning. A finished basement hides the slab and walls, so the company may need to find a pipe route through closets, utility rooms or the garage. A house with additions may have several foundation sections that each need their own suction point. A crawl space may need a sealed liner. A basement with a sump pit that connects to drain tile around the footing can often use the pit as a suction point once it has an airtight cover.
- Tell the company about any finished or planned remodeling, because walls and floors can change where a pipe goes.
- Mention additions, split levels, walkout basements and attached garages. Each can behave differently.
- Point out the sump pit, floor drains and any visible cracks, since these are known radon entry points.
- Say if you plan to sell soon, since documentation of the system and a post-installation test can matter to buyers.
Follow-Up Testing and Records
A radon system is not finished until a test shows it is working. Ask whether the proposal includes a post-installation test, who performs it and how soon after installation it happens. Keep the test result, the installer's paperwork and the warranty together with your house records. If you retest later and the number has climbed, the installer's records make it easier to diagnose.
Retesting after renovations or changes to the house is sensible, since sealing, new heating or ventilation, or foundation work can change how radon moves. Our radon testing page explains how to retest properly.
Common Questions
Why do radon mitigation proposals differ so much?
Houses differ in foundation type, layout and radon level, so proposals may describe different systems. Compare the number of suction points, the pipe route, the sealing and the warranty side by side.
Should I get more than one proposal?
Comparing at least two proposals is common practice. Make sure each company has seen the same house and written down what it will do.
Does a radon system need maintenance?
Fans run continuously and eventually wear out, and you should check the gauge and retest periodically. Ask the company about the fan warranty and expected service life.
