System repairs and upgrades
What we service
Fans wear out, joints loosen, and radon can creep up after remodels or foundation changes. We troubleshoot and repair existing mitigation systems across Central Illinois with clear diagnostics and code-minded fixes, especially in service corridors through McLean, Champaign, and Peoria counties.
From manometer readings and noise complaints to full fan swaps and discharge corrections, we verify the suction field before we recommend parts—so upgrades fix the problem, not just the symptom.
How we approach repairs & upgrades
Six pillars—from diagnosis to verification—so your system performs after we leave.
-
System review & symptoms
Manometer behavior, fan age and noise, visible stack condition, and any history of tests or remodels—so we are not guessing which layer of the system failed.
-
Fan & electrical service
Replacement with correct sizing for static pressure and flow, secure mounting, weather sealing, labeling, and safe disconnect practices where the existing install needs attention.
-
Pipe, joints & discharge
Leaks at couplings, unsupported runs, condensation trouble, and discharge height or location issues—corrected so soil gas exits above the roofline and away from openings.
-
Sealing & suction field
Short circuits through slab gaps, sumps, or crawlspace edges addressed when they undermine depressurization—coordinated with any new encapsulation or finish work.
-
Upgrades & layout changes
Basement finishes, additions, or rerouted stacks that need a revised path—planned alongside new or extended mitigation when a repair alone is not enough.
-
Verification & next steps
What changed, what to watch on the gauge, and how post-repair radon testing fits your timeline or real estate needs—plus documentation you can share with buyers or inspectors.
Ready when you are
Share your foundation type, timeline, and any test result you already have. No radon reading yet? That is okay—we can still walk you through options, including how to get a reliable reading before mitigation. Prefer reading first? See the radon FAQ.
