Existing radon system not performing? Manometer looks wrong? We inspect, diagnose, and repair underperforming radon mitigation systems across the Denver metro — often the same day.
Many Denver homes have radon mitigation systems installed in the 1990s and 2000s — some performing well, others quietly failing. Fan motors wear out, suction points get clogged with slab movement, and pipe connections loosen over years of thermal cycling. The manometer on the system is your first indicator something is wrong: if the fluid levels look equal, the fan has likely failed.
Signs your system may need attention: manometer fluid levels are equal (no pressure differential — fan is not drawing), fan is audibly louder than normal (bearing wear), a recent re-test came back elevated despite having an existing system, or you're preparing to sell and want documentation that the system is functional.
An inspection from 5280 Radon includes: visual check of all accessible pipe and connections, manometer reading and interpretation, fan performance assessment (suction test at the suction point), and a written report with findings and recommendations. If repair is needed, we quote it on the spot.
System inspection is right for you if you're buying or selling a home with an existing radon system and want to verify it's functional, your most recent radon test showed elevated levels despite having a system, your manometer doesn't look right and you're not sure if the system is working, or it's been more than 5 years since anyone looked at the system and you want peace of mind.
We start with a visual inspection of all accessible components: pipe condition, fan mounting, exhaust outlet, and manometer. We perform a suction test at the suction point to measure actual negative pressure being achieved. We compare this to expected performance for the fan model and sub-slab conditions.
Common repairs: fan replacement (most common — fans last 15–25 years, older systems often just need a new fan), suction point cleaning or addition (if soil migration has blocked the original point), pipe extension or re-routing (if exhaust placement is problematic), and manometer replacement (simple and inexpensive).
Inspection: [INSPECTION PRICE]. Fan replacement: [FAN REPLACEMENT PRICE]. Additional suction point: adds to base install cost. See full pricing page for reference ranges.
