Radon Quote Index
Public aggregate ranges, not private submissions.
The index groups quote submissions and lead-derived planning signals by county, state, foundation, and result band. Exact ZIPs, names, emails, phones, notes, IP addresses, and user agents stay out of the public export.

Why this matters
The model gets stronger when real quotes arrive.
Public radon data explains risk. Housing and cost inputs explain the estimate. Observed quotes tell us where real projects are above, below, or outside the model range.
01
County benchmark
ZIP routes the quote to the county so local cost ranges can learn from real projects without exposing a full address.
02
Foundation context
Basement, slab, crawl-space, sump sealing, and fan replacement are separated because they do not price the same.
03
Deal pressure
A failed inspection quote, a seller credit, and a planned homeowner install are different decisions. The ledger keeps that difference visible.
Shareable benchmark packet
The best signal is one real local quote.
Agents, inspectors, and homeowners can use this packet after a failed inspection or contractor call. No address is needed; the useful parts are ZIP, result band, foundation, status, price, and scope.
Failed inspection quote
4.0+ result, inspection deadline, quoted price, final price if installed, and whether the ask became repair or credit.
Seller credit signal
Credit amount, quote basis, foundation clue, and whether the deal used concession, escrow, repair, or price reduction.
Paid install quote
Final price, system scope, sump seal or fan replacement, slab or crawl-space complexity, and timeline.
Commercial or multifamily quote
Building type, result band, testing status, quote status, and any scope clue without business contact details.
Copy/paste request
If you received a radon quote, add the ZIP, reading, foundation type, quoted price, final price if paid, and whether it was a failed inspection, seller credit, or planned install. Remove names, phone numbers, exact addresses, and contractor contact details.
