How Colorado Radon Experts Builds Its Cost Estimates and Cites Its Sources
This page documents the data sources, methodology, and limits behind every cost figure, mitigation recommendation, and state-rule citation on Colorado Radon Experts. Our pages are designed to answer one practical question: based on public data and your situation, what should you do next? The cost ranges shown are planning estimates derived from EPA radon-zone data, EIA electricity rates, manufacturer fan specifications, the CDPHE credentialed-contractor directory, and AARST-ANSI installation standards.
What Colorado Radon Experts Does (and Does Not Do)
Colorado Radon Experts is an advertising and lead-routing platform. We connect Colorado homeowners, real-estate professionals, and property managers with NRPP-certified and CDPHE-licensed radon mitigation specialists serving Colorado. The certified partner contractor performs all actual radon testing and mitigation work under their own state licensing, business name, and insurance.
What we do
- Publish Colorado-specific radon cost ranges grounded in public data
- Route qualified Colorado homeowner inquiries to certified partner contractors
- Cite EPA, CDPHE, ALA, AARST, and EIA primary sources
- Track Colorado SB 23-206 disclosure language and Colorado DORA radon licensing requirements
- Show source-level dates on cost data tables
- Accept corrections via the contact page
What we do NOT do
- We do not perform radon testing or mitigation work ourselves
- We are not a medical provider, law firm, or government agency
- We are not a certified radon laboratory
- We do not know the radon level inside a specific home unless tested under valid conditions
- We do not guarantee contractor pricing or availability — final quote is from the partner contractor on-site
- We do not replace the EPA test-then-mitigate decision flow
How We Calculate Colorado Radon Mitigation Install Cost Ranges
Colorado Radon Experts install cost ranges are planning estimates derived from three inputs: public cost references (EPA, American Lung Association 2024 healthcare-provider decision-support tool, AARST industry norms), regional labor-market adjustments for Colorado metros, and foundation-type cost differentials. Final pricing is set by the NRPP + CDPHE certified partner contractor after a free on-site assessment.
| Input | Value | Source |
|---|---|---|
| Active sub-slab depressurization (typical) | $800 – $2,200 | EPA + ALA 2024 + Colorado partner-contractor reported actuals |
| Crawl space sub-membrane | $1,500 – $3,500 | AARST-ANSI MAH-2023 standard |
| Block-wall depressurization | $2,000 – $4,000 | AARST-ANSI SGM-SF-2017 standard |
| Drain-tile depressurization | $1,500 – $3,500 | AARST industry norms |
| Passive system retrofit | $500 – $1,500 | EPA RRNC builder guidance |
| Colorado state typical median | $1,400 | Triangulation of CDPHE credentialed-contractor reported actuals + EPA/ALA national median |
How We Calculate Colorado Radon Mitigation Monthly Operating Cost
Colorado Radon Experts monthly operating cost estimates ($10–$14/month all-in for an active sub-slab depressurization system) come from three inputs: (1) fan power draw per published manufacturer specifications, (2) Colorado's 2025 EIA residential electricity rate of $0.135/kWh, and (3) amortized fan replacement + biennial re-testing. Detailed breakdown:
| Input | Value | Source |
|---|---|---|
| Fan power draw — RadonAway GP-301 | 65W continuous | RadonAway published spec |
| Fan power draw — Festa AMG | 80-100W | Festa published spec |
| Fan power draw — Fantech HP190 | 80W | Fantech published spec |
| Monthly kWh (65W typical fan) | ~47 kWh | Calculated: 65W × 24h × 30 days |
| Colorado residential electricity rate | $0.135/kWh | EIA 2025 state average (Colorado) |
| Monthly electricity cost | $6 – $8 | Calculated: 47 kWh × $0.135 = $6.35 |
| Fan replacement (amortized) | $3 – $5/mo | $250-$400 fan ÷ 60-96 months (5-8 yr typical lifespan) |
| Biennial re-testing (amortized) | ~$1/mo | EPA recommends every 2 years · $15-$30 short-term kit |
| Total monthly operating cost | $10 – $14 | Sum of components above |
| Annual operating cost | $120 – $170 | First 5-7 years; fan-replacement year adds $350-$600 one-time |
Primary Data Sources
Every cost figure, action-level claim, and Colorado state-rule citation on Colorado Radon Experts links back to one of these primary sources. Health and action-level claims are tied to EPA, WHO, NAS, or American Lung Association. State-specific rule citations link to the official Colorado state resource so users can verify current requirements.

The Limits of Our Cost Data
Colorado Radon Experts cost ranges are planning estimates, not contractor quotes. They are designed to reduce uncertainty before a Colorado homeowner buys a test kit, requests quotes, or negotiates a real-estate credit — not to replace the contractor's on-site assessment.
- We cannot know the radon level inside a specific Colorado home without a valid test under closed-house conditions. EPA zone data is regional risk context, not a home-specific result.
- We cannot replace an on-site contractor inspection. Final mitigation pricing depends on foundation type, basement layout, radon source location, accessibility for venting, and any cosmetic restoration needs — all of which require physical inspection.
- We cannot guarantee that Colorado state licensing or disclosure rules have not changed after our last source refresh. Always link to the official CDPHE resource (or call CDPHE at 303-692-3442) to verify current rules.
- We do not provide medical, legal, or engineering advice. For health questions, contact a qualified medical provider. For legal questions about Colorado SB 23-206 disclosure obligations, consult a Colorado real estate attorney.
- We do not guarantee Colorado partner contractor availability. Lead-routing depends on the partner contractor's current capacity in your service area.
Editorial Standards
- Primary-source attribution. Every health, action-level, electricity-rate, and Colorado state-rule claim links back to EPA, WHO, NAS, ALA, EIA, CDPHE, or AARST. We do not paraphrase data without source attribution.
- Source freshness dates. Cost tables and state-rule sections show source-level retrieval dates where applicable (rather than implying every page is reviewed daily).
- Operating-model disclosure. Colorado Radon Experts is a lead-routing affiliate connecting Colorado homeowners with certified mitigation specialists. We are not the mitigation contractor. This is disclosed on every page footer.
- Correction protocol. If a state link is stale, a rule summary is wrong, or a cost assumption looks off for a Colorado local market, send the source and county through our contact page and we will update.
- No fabricated authority. We do not claim certifications, partnerships, or memberships we do not hold. Partner-contractor credentials (NRPP, CDPHE) are verified independently before any lead routes to that contractor.
- No editorialized testimonials. Testimonials and reviews shown are sourced from real Colorado partner-contractor customers with verified identities. We do not write or paraphrase reviews.
Corrections, source updates, and methodology questions
