Commercial Radon FAQ — Denver

What is commercial radon mitigation in Denver?
Commercial radon mitigation in Denver involves installing sub-slab depressurization systems, crawl space encapsulation, and ventilation upgrades in office buildings, warehouses, schools, retail spaces, and multi-family units. Commercial systems are scaled to the building's square footage and HVAC layout — they differ significantly from residential systems in design, permitting, and ongoing monitoring requirements.
How is commercial radon testing different from residential testing?
Commercial radon testing in Denver, CO typically follows EPA protocols for large buildings (EPA 402-K-93-001), which require multiple test devices per floor and longer measurement periods than home tests. Certified radon measurement professionals deploy long-term alpha track detectors or continuous electronic monitors across all occupied and sub-occupied zones.
Which Denver radon contractors handle commercial buildings?
Several radon contractors serving Denver hold NRPP or NRSB commercial certifications for large-structure mitigation and testing. Contact the specialists listed on this page to confirm commercial service availability, as some firms specialize exclusively in residential properties.
What radon level triggers mitigation in a commercial building?
OSHA and the EPA both recommend action at or above 4 pCi/L for occupied commercial and industrial spaces. Many Denver property managers choose to mitigate at 2–3 pCi/L to stay well below regulatory thresholds and reduce liability exposure. Schools and healthcare facilities often target sub-2 pCi/L levels.
How much does commercial radon mitigation cost in Denver?
Commercial radon mitigation systems in Denver typically range from $1,500 for small retail suites to $25,000+ for large industrial or multi-story buildings. Cost depends on slab area, number of sub-slab suction points, existing HVAC infrastructure, and post-mitigation verification testing.
