Radon mitigation quotes in Algonquin
Algonquin grew from a Fox River crossing into a Randall Road corridor boomtown, and its housing tells that story in two chapters: the older river-valley streets near downtown, and the broad 1990s–2000s subdivisions and townhome communities that climbed the hill west of the river. Radon shows up in both chapters — and in townhomes it arrives with an extra question about shared walls and associations that this page takes seriously.
We introduce Algonquin homeowners to up to three independent, IEMA-licensed radon mitigation contractors for free quotes. The introduction costs nothing and obligates nothing; contracts are directly between you and the contractor.
Algonquin and McHenry County
Algonquin straddles the McHenry–Kane county line, with the village core in McHenry County and southern sections reaching into Kane. We route all of ZIP 60102 through our McHenry territory; Illinois’ statewide IEMA-OHS licensing makes the line irrelevant to which contractors can quote you.
If the result surfaced in a transaction
Corridor subdivisions turn over on the family-move cycle, and radon testing is standard inspection fare. Illinois treats results as disclosure items — shared, then negotiated. Townhome transactions add one wrinkle: mitigation on an attached unit is still normally a per-unit system, but exterior routing may touch association rules, so surfacing HOA requirements during the negotiation (not after) keeps closings smooth.

The housing you’re mitigating
West-side Algonquin is late-vintage suburban construction: poured foundations, full basements, attached garages — the tidy single-point install profile. Townhome and duplex communities cluster along the corridor; end units and interior units alike sit on their own slabs and are mitigated individually, with routing planned around association aesthetics. The older river-district homes bring the usual pre-war variables: block foundations, additions, and designs that reward experience.
Deciding well in Algonquin
- Townhome owners: confirm association exterior standards early and tell bidders, so routing is quoted correctly the first time.
- End unit or interior unit, the slab under you is yours — test it rather than inferring from a neighbor’s result.
- Older river-district homes deserve bidders who can talk specifically about pre-war foundations.

Algonquin questions, answered straight
Our townhome tested at 4.8. Does the association fix this or do we?
Read your declarations, but in most Illinois townhome associations the interior environment — and usually the system serving a single unit — is the owner’s responsibility, while the association governs what may be attached to exterior surfaces. In practice: you hire the licensed contractor, and the association approves the routing. Contractors who work attached housing handle that paperwork routinely.
The unit next door tested low. Doesn’t our shared wall mean we should match?
No — attached units regularly test differently. Each unit sits on its own slab section with its own cracks, penetrations, and pressure behavior, and the shared wall says nothing about what rises from the soil below your specific footprint. Test your unit; treat your unit’s number as the only one that is yours.
Which county are we in, and does the split matter for hiring?
Algonquin spans McHenry and Kane counties, and it matters not at all for radon: licensing is statewide through IEMA-OHS, and we route the whole village through one territory so every Algonquin request follows the same path. Save the county question for the assessor’s office.
What should we expect to pay?
We publish a detailed cost guide rather than quoting from a city page, because Algonquin spans simple single-slab installs and multi-zone older homes. Broadly, straightforward suburban systems in this region are commonly quoted in the low four figures, with complexity — extra suction points, difficult routing, older foundations — moving the number up. Free quotes from two or three licensed bidders will bracket your house quickly.
