Commercial Radon Services
Commercial Radon Mitigation in Denver & the Front Range
Schools, daycares, offices, and multifamily buildings across Colorado are required to manage radon—and larger footprints demand real engineering. We design and install ANSI/AARST-compliant commercial systems with documented, verified results and minimal disruption to your operations.
- Commercial standards compliant
- ANSI/AARST
- Guaranteed post-mitigation level
- 2.7 pCi/L
- Documented pre & post testing
- 100%
Built for Buildings
Radon Engineering at Commercial Scale
Radon is not just a residential problem. Colorado sits in EPA Zone 1—the highest radon-risk designation in the country—and commercial buildings sit on the same uranium-rich soil as the homes around them. Schools and childcare facilities face testing requirements, and commercial real estate transactions increasingly demand radon documentation.
A commercial building cannot be fixed with a residential system. Large slabs, compartmentalized foundations, multiple additions, and complex HVAC all change how radon moves through a structure. We perform sub-slab communication testing, design multi-point suction networks sized to your footprint, and integrate exhaust routing with your roofline and mechanical systems—then verify everything with documented post-mitigation testing.
Multi-Point Systems
Suction networks engineered from real sub-slab communication testing—not guesswork—so every zone of the building is depressurized.
Code Compliant
Every installation meets ANSI/AARST commercial standards and local building code, with documentation for your records.
Verified Results
Full pre- and post-mitigation testing with clear reporting you can hand to regulators, buyers, or your board.
Minimal Disruption
We phase work around your operations—including after-hours and weekend installation—so your building keeps running.
Schools, Offices & Public Buildings
Compliance Without the Headache
Colorado schools and childcare facilities are subject to radon testing requirements, and public and commercial buildings face growing disclosure expectations. We handle the full compliance picture—assessment, engineering, installation, and the documented verification testing that proves your building is protected.
- Radon assessments and diagnostics for buildings of any size
- Systems that integrate cleanly with existing mechanical rooms and HVAC
- Complete documentation packages for regulators, districts, and boards
- Ongoing monitoring options to keep levels verified year after year
Multifamily & Developments
From Single Buildings to Entire Sites
Multifamily properties multiply the radon challenge: many units, shared foundations, and residents who expect safe air. We scale from a single apartment building to full multi-building developments, with rough-in work during construction or retrofit systems for existing properties.
- Multi-building and phased-site radon mitigation planning
- Rooftop exhaust routing engineered for multi-story structures
- Unit-level and common-area testing with consolidated reporting
- Retrofit solutions that respect occupied units and quiet hours
From the Field
Real Projects, Real Results
Our Process
How Commercial Mitigation Works
A commercial project is an engineering exercise, not a one-size install. Here is exactly how we take your building from unknown risk to documented protection.
Assessment & Diagnostics
We walk the building, review plans, and run sub-slab communication testing to map how air actually moves beneath your foundation.
Engineered System Design
You receive a system design scaled to your footprint—suction point count, fan sizing, exhaust routing, and a firm quote with a compliance plan.
Install, Verify & Document
We install in phases around your operations, then deliver post-mitigation test results and a full documentation package proving levels below 2.7 pCi/L.
FAQ
Commercial Radon Questions
Have a question we haven't covered? Call us at (303) 990-4506 and we'll walk you through it.
Do commercial buildings in Colorado legally need radon mitigation?
Colorado requires licensed radon professionals for testing and mitigation, and schools and childcare facilities face specific testing requirements. Beyond regulation, commercial transactions and tenant expectations increasingly demand documented radon management. We keep you compliant with verified, documented results.
How is commercial radon mitigation different from residential?
Scale and engineering. Commercial buildings have larger, often compartmentalized slabs and complex HVAC that affects pressure relationships. Commercial systems typically use multiple suction points, larger fans, and rooftop exhaust—all designed to ANSI/AARST commercial standards rather than residential ones.
Will installation disrupt our business or school schedule?
No. We phase installation around your operations, including after-hours and weekend work. Most zones can be completed without closing any part of the building, and we coordinate directly with your facilities team.
How much does commercial radon mitigation cost?
It depends on building size, foundation layout, and how many suction points the diagnostics call for. After our free on-site assessment and communication testing, you receive a firm engineered quote—no estimates that balloon mid-project.
Do you provide documentation for compliance and transactions?
Yes. Every commercial project includes pre- and post-mitigation test data, system specifications, and compliance documentation suitable for school districts, regulators, lenders, and real estate transactions.
