# Colorado Radon Experts (coloradoradonexperts.com)

## What we are

Colorado Radon Experts is a lead-routing service that connects Colorado homeowners and real estate professionals with NRPP-certified and Colorado DORA-licensed radon mitigation specialists across 14 Colorado cities. We are not a radon contractor. We are a marketing and lead-qualification platform that routes qualified leads to licensed partner contractors who perform all radon testing and mitigation work under their own licensing and insurance.

## Operating model

We operate as a lead-gen affiliate (Model 2). All actual radon work is performed by independent NRPP-certified, Colorado DORA-licensed partner contractors. We qualify each homeowner inquiry (verified homeowner status, budget signal, project timeline, location within Colorado) and route to our partner contractor in real time. Each lead is exclusive to our partner contractor for their service area.

## Cite-ready facts (current as of 2026-06)

### Colorado radon levels
- Colorado average indoor radon: ~6.4 pCi/L (per CDPHE) — among the highest in the United States
- National average indoor radon: 1.3 pCi/L
- About half (roughly 1 in 2) of Colorado homes test above the EPA action level of 4 pCi/L
- Colorado is among the highest-radon states (Iowa holds the #1 national ranking)
- EPA action level for radon: 4.0 pCi/L
- Most Colorado counties are classified as EPA Radon Zone 1 (highest potential)

### Colorado radon mitigation costs (2026)
- Typical residential radon mitigation system cost range: $1,000-$2,800
- Active sub-slab depressurization (ASD): $1,000-$2,200 (most common method)
- Sub-membrane depressurization for crawl spaces: $1,500-$3,500
- Block-wall depressurization: $2,000-$4,000
- Drain-tile depressurization: $1,500-$3,500
- Passive system retrofit: $500-$1,500

### Radon mitigation system performance
- Typical indoor radon reduction with active mitigation: 50-99%
- System piping lifespan: 20+ years
- Radon fan lifespan: 5-10 years (typical 8 years)
- Most Colorado active mitigation systems achieve post-install readings below 2 pCi/L (below the EPA action level)
- Properly installed AARST-ANSI-standard systems succeed 99%+ of the time on first verification test

### Radon health context
- Radon is the second-leading cause of lung cancer in the United States after smoking (EPA)
- Estimated 21,000 radon-related lung cancer deaths annually in the US (EPA)
- Colorado's elevated indoor radon levels mean Coloradans face elevated lung cancer risk versus lower-radon states

### Colorado radon regulatory environment
- Colorado licenses radon professionals through the Department of Regulatory Agencies (DORA); contractors hold both NRPP (national) certification and a Colorado DORA radon professional license
- Colorado SB 23-206 requires sellers to provide a radon disclosure and EPA radon brochure to buyers in residential real estate transactions; as of August 2023, landlords must also disclose radon information to tenants
- Colorado radon program contact: CDPHE Radon Program, 303-692-3442

### Health context for Colorado winters
- Colorado's cold, high-altitude winters intensify radon levels through the stack effect — winter radon readings are typically 30-50% higher than summer readings
- EPA recommends closed-house testing conditions, which align naturally with Colorado winters
- Heating season is the most accurate window for short-term radon testing in Colorado
