Radon Mitigation & Testing in Shorewood
Shorewood's subdivisions went up fast — nearly 38% of the village's homes were built between 2000 and 2009 alone — and almost all of them landed in the gap between radon being understood and Illinois requiring builders to do anything about it.
A village built inside the radon code gap
The median Shorewood home dates to 2001, and 37.9% of the village's housing went up between 2000 and 2009 — the heart of the boom that filled in the DuPage River corridor west of Joliet. Illinois didn't require radon-resistant construction in new homes until June 1, 2013. Run those dates together and the conclusion is blunt: nearly all of Shorewood was built by crews who knew radon existed and weren't yet required to defend against it. Full basements, tight modern envelopes, no vent pipe. That combination is precisely what an active sub-slab system was designed for. It's a young housing stock for a place with old roots: Shorewood was settled in 1830 and incorporated as a village in 1957, and most of the homes we work with here are decades younger than the village charter.
Owners, not renters — which makes the math easy
Shorewood is about as owner-occupied as a town gets: 95.5% of its roughly 6,600 occupied homes, with a median household income around $122,000. If you own the basement you breathe in every night, a one-time install in the $1,200–$1,700 range that permanently drops a radioactive exposure is among the best health-per-dollar spends available on the house. And newer construction is the cheap end of mitigation: one clean suction point, an unfinished utility corner to route through, done in a day with a permit from the Village of Shorewood Building Department.
Test first — the river doesn't decide, the soil does
Neighbors along the DuPage River sometimes assume the riverside ground drains radon away, or concentrates it. Neither is reliable: radon rides on the glacial soil under the subdivision, and readings jump house to house even on one cul-de-sac. Will County's official Zone 2 "moderate" label predicts 2–4 pCi/L, while the American Lung Association's analysis of Illinois Emergency Management Agency testing data shows over 40% of tested Illinois homes at or above 4.0. An $8 county kit or a licensed 48-hour test settles your house's number for less than dinner out.
The same boom-era math plays out around the rest of Will County — we cover Crest Hill, Lockport, and Plainfield with the same licensed approach.

My Shorewood house was built in 2005 — doesn't that mean it already has radon protection?
No. Illinois didn't require passive radon-resistant construction in new homes until June 1, 2013, and the median Shorewood home dates to 2001 — with 37.9% of the village built in the 2000s alone. That means most Shorewood houses, including yours, went up with full basements and tight, modern envelopes but no vent pipe, no seal, nothing built in. It's an assumption worth testing rather than trusting: we run an $8 county kit or a licensed 48-hour test to find out where your house actually lands.
Does living along the DuPage River change my radon risk?
Not in any way that helps or hurts you. Radon comes from uranium traces in the glacial soil under the whole subdivision, not from surface water, so a house three blocks from the DuPage River can test completely differently than the one next door to it. Will County's Zone 2 label predicts a "moderate" 2–4 pCi/L, but state data shows over 40% of tested Illinois homes at or above the 4.0 action level. The only way to know your number is to test your house, not your street.
I own my Shorewood home outright — is a system really worth $1,200–$1,700?
For a village that's 95.5% owner-occupied, yes — you're the one breathing that basement air every night, not a landlord weighing it against rent. A newer Shorewood house is also the cheapest kind to fix: one suction point, an unfinished utility corner to route through, done in a day. Spread over the years you'll own the house, a one-time install that permanently cuts a radioactive exposure is one of the better health-per-dollar repairs available, and it's a number buyers will ask about eventually anyway.
How long does a radon system install actually take in a typical Shorewood two-story?
One day, in most cases. Shorewood's 2000s-era slabs are the straightforward version of this job — a single suction point, PVC routed through an unfinished basement corner or garage, and a fan mounted where you won't hear it. We handle the Village of Shorewood Building Department permit as part of the quote, and the job wraps with a post-install test confirming the number actually dropped before we call it done.
