What a Lexington homeowner can safely DIY for radon system vent odor
A reasonably handy homeowner can inspect the exterior vent pipe for visible gaps, check that the fan is running, and look for loose fittings near the vent outlet. Radon gas itself is invisible, odorless, and tasteless, so any smell near the vent is not a reliable way to judge radon levels. Sealing a small exterior joint with appropriate caulk is a low-risk task.
What you should NOT do yourself on a radon system in Lexington
Cutting into vent piping, rewiring or replacing the fan, or altering system design is best left to a pro. Kentucky defines a mitigation contractor as a person certified by a proficiency program who performs radon work for compensation, and registered contractors carry at least $500,000 in general liability coverage. Mistakes can reduce the system's radon reduction performance.
How much radon system vent odor repairs cost in Lexington
EPA's consumer guide puts a typical fan replacement at about $200 to $350 including parts and labor. Adding a vent fan to an existing passive system runs about $300. A full mitigation system in the Lexington area averages between $1,200 and $3,000.
When to call a pro for radon system vent odor in Lexington
Call a pro if the odor persists after simple checks, the fan is silent or failing, the system was never tested after installation, or you want confirmation radon levels are actually reduced. Testing is the only reliable way to know if radon is present. Ask the pro for proof of Kentucky registration and NRPP or NRSB certification.
