Radon mitigation quotes in Lombard
Lombard filled out in the postwar decades, and the Lilac Village’s streets still read that way: ranches, split-levels, and raised ranches on modest lots, most with basements or partial basements and a healthy population of sump pits. That housing profile turns out to matter for radon work — split-level foundations mix levels and slabs in ways that reward an experienced design, and sump pits often give contractors a ready-made pathway under the house.
If your test came back at or above 4 pCi/L, we route requests to independent, IEMA-licensed mitigation contractors covering Lombard, and check coverage before asking for your contact details. Free to you, no obligation, and every quote is the contractor’s own.
Lombard and DuPage County
Lombard sits in east-central DuPage County between Glen Ellyn and Villa Park; ZIP 60148 routes through our DuPage territory along with the neighboring communities homeowners here compare notes with — Villa Park, Addison, Glendale Heights, and Downers Grove.
If the result surfaced in a transaction
Lombard’s price points keep it busy with first-time buyers, and first-time buyers lean hard on their inspectors — radon tests are common even on modest transactions. Illinois requires sellers to disclose known radon information and provide the state pamphlet; what happens after an elevated result is negotiated. For sellers, a pre-listing test plus a quote in the drawer is cheap insurance against a mid-contract scramble.
Those duties are set in Illinois, not in DuPage 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
Split-levels and raised ranches complicate the simple mental model of “one slab, one pipe.” A Lombard split may have a basement section, a slab-on-grade family room, and a crawl under part of the footprint — and a good mitigation design addresses whichever zones communicate with the soil. Homes with drain tile and a sump often mitigate efficiently via a sealed sump-pit suction approach; contractors will tell you if your house is one of them.
If that describes your house, the next question is usually what the work costs and whether you need it at all. Our guide to what mitigation costs across Suburban Chicagoland sets out the local price drivers, and how mitigation is actually done in Suburban Chicagoland covers the system types that suit these foundations. If you have not yet confirmed the reading, start with the difference between testing and mitigation — they are separate jobs, often done by separately credentialed people.
Two general guides sit behind those local pages: how much radon mitigation costs — commonly quoted ranges by home type and the six factors that move a quote — and how a mitigation system works, which explains the suction point, pipe, fan and manometer a Lombard quote should itemise.
Neighbouring towns share DuPage’s geology and its housing eras more than they share a postcode, so a result two streets over in the next municipality is often more informative than one across the city. Radon across DuPage County covers what the county line does and does not change — and it changes less than people expect, because Illinois licenses radon work statewide rather than county by county.
Who is licensed to do this work near Lombard
Illinois does not leave this to guesswork, and neither should you. IEMA-OHS licenses radon mitigation professionals for the whole state and publishes the active list itself — no account, no fee, no intermediary. It is the same list a search engine returns above the review sites, and it is the only list of DuPage County mitigation supply that nobody paid to appear on.
- Search IEMA’s active licensee register — filter by licence type: mitigation and by service county or city to see who covers Lombard.

What a listing does and does not tell you
- It shows who currently holds an Illinois mitigation licence — not who is good, insured, available, or priced fairly.
- A licence covers a person or business, not a specific job. Confirm the licence you were quoted by is the one doing your work.
- Measurement and mitigation are separate Illinois licences. The list linked here is the mitigation list.
- Nobody on it has any relationship with Radon Connect. We do not place, rank, endorse, or receive anything from the businesses Illinois licenses.
So the register narrows the field; it does not pick for you. Ask every business you shortlist for its licence number and check it yourself — that habit is your protection, and how Illinois radon licensing works, and how to verify a number walks through it. When the quotes arrive, compare them on the eight lines that actually differ rather than the total at the bottom.
Prefer not to work the list yourself? Tell us the reading and the postcode and we will check coverage before asking for a single contact detail — start a request, and the confirmation tells you exactly what happened to it, including when the answer is that nobody covers you yet.
Deciding well in Lombard
- For a split-level, ask bidders which foundation zones they will treat and why; that is where designs diverge.
- A sealed sump lid with a suction point can be an efficient route — but the pit and drain tile layout determine it, not preference.
- Compare fan warranties and the included post-mitigation test, not just price.
A reading in the next town is often more informative than one across Lombard, because DuPage’s housing eras and soil do not stop at a municipal line — radon in Glen Ellyn and radon in Downers Grove cover the neighbouring picture, and what a system costs across Suburban Chicagoland sets out the price drivers before you start collecting numbers.

Lombard questions, answered straight
How does mitigation work on a split-level?
By treating the house as its zones. A typical design draws from beneath the basement slab and, where testing or diagnostics justify it, adds a second suction point under the slab-on-grade section or a membrane over any crawl area — often all on one fan. The right answer is house-specific, which is exactly why comparing two or three licensed designs is worthwhile.
We have a sump pit with drain tile. Does that help or hurt?
Usually it helps. Drain tile is a network of perforated pipe under and around the foundation; sealing the sump with an airtight lid and drawing suction from it can depressurize a wide area beneath the house efficiently. Your pump keeps working normally under the sealed lid. Whether it is the best route for your house is a design call the contractor makes on-site.
Is 3.1 pCi/L worth doing anything about?
That result sits in EPA’s “consider action” band between 2 and 4 pCi/L — no recommendation forces your hand, and no Illinois law does either. Households with heavily used basement space, young kids, or plans to finish the basement often act in that band; others retest long-term and decide from the average. Both are defensible.
Will a system change how the house looks from the street?
Exterior runs are usually routed on the rear or side elevation, painted to match, or avoided entirely by routing through the garage or an interior chase to the roof. If curb appeal matters to you, say so — routing options are quotable line items, and the Lilac Village has plenty of systems you have walked past without noticing.
