Radon mitigation quotes in Rochelle
Rochelle sits in southern Ogle County at a long-standing rail crossroads, a working city whose housing spans a century — older neighborhoods near the center, postwar expansion, and newer subdivisions built as logistics and agribusiness employment grew.
When a Rochelle test comes back at or above 4 pCi/L, the work goes to independent, IEMA-licensed mitigation contractors. We make the introduction; the licensed contractor does the work.
Rochelle and Ogle County
Rochelle routes through our Ogle County territory along with Byron, Oregon, Davis Junction, and Stillman Valley. Northern Illinois broadly falls in EPA’s Zone 1, which supports testing every home here rather than assuming a result in either direction.
If the result surfaced in a transaction
Rochelle’s market includes a meaningful share of rental and investor-held property alongside owner-occupied sales, and Illinois disclosure duties attach to all of it: known radon information travels with the sale. Buyers of formerly tenant-occupied homes should assume nothing was ever tested and order their own measurement during the inspection window.
Those duties are set in Illinois, not in Ogle County — Illinois radon disclosure rules has the statute and the agency behind it, and the Illinois home-sale playbook covers the part no statute decides: who pays.
The housing you’re mitigating
Older central Rochelle brings block and brick foundations, occasional stone, and additions layered over decades. Postwar blocks are ranch-dominated with partial or full basements. The newer subdivisions are conventional poured construction — the straightforward single-suction-point profile where quotes cluster tightly and installation finishes in a day.
Radon results do not stop at a municipal boundary, and neither do the contractors quoting here: the same Ogle County soil and the same building era run through Byron, which is why a reading in one of them is worth knowing about when you are interpreting yours.

Rochelle questions, answered straight
We are buying a rental property. Any different radon obligations?
The sale carries the same Illinois disclosure duty — known radon information must be shared. What changes practically is that rentals are less likely to have been tested at all, so order your own measurement rather than hoping for records. Keeping written test and mitigation documentation is simply good practice for any owner of rental property.
The house tested 4.1. Is that really different from 3.9?
Not biologically — radon risk is a continuous curve, and 4 pCi/L is where EPA plants its action flag for practical and policy reasons. What the number does change is the recommendation: at or above 4, the standing advice is to reduce it. Do not spend energy on the second decimal; decide from the band.
Can a licensed contractor installs a system ourselves to save money?
In Illinois, anyone performing mitigation services for others must hold an IEMA-OHS license, and even on your own home the design judgment is the product you are actually buying — where to pull, how much fan, what to seal. A poorly placed system can run for years while accomplishing very little, and only a verification test would tell you.
Our neighbour tested low. Does that tell us anything about our house?
Very little. Radon entry depends on what is directly beneath your foundation, how your slab is penetrated, and how your house moves air — soil permeability, cracks, sump openings, and stack effect all change house by house. Two Rochelle homes built by the same builder in the same year on the same street routinely land on opposite sides of 4 pCi/L. A neighbour's result is a reason to test, never a substitute for it.
What happens if the post-mitigation test still comes back above 4?
A reputable contractor treats that as unfinished work, not a closed job. The usual next steps are sub-slab diagnostics to find where suction is not reaching, then adding a second suction point, upsizing the fan, or sealing a pathway that was missed — a floor-wall joint, an untrapped drain, a crawl space under an addition. Before you sign anything in Rochelle, ask what the contractor does in this scenario and whether the follow-up work and the retest are included in the original price.
