Radon mitigation · Florida

Does Florida regulate radon mitigation systems, and what do they cost?

Short answer

A radon mitigation system pulls soil gas from beneath the floor and vents it outside. The Florida statutes and DBPR pages in our sources carry no radon rule, so ask any company that cites one to show you the page. An installed system runs $875 to $1,975 per system, installed in our model, an estimate, not a quote.

The permit statute, applied to a fan and a vent pipe

DBPR's list of contractor classes has no radon category. Read the class on the license record of any company you call.

Section 553.79 requires a permit to repair or alter a building, with an exemption under $7,500 that excludes electrical, plumbing and structural work and flood hazard areas. A system includes a fan on a power supply, so ask the office whether it files that wiring as electrical work.

A mitigation system draws radon from under the floor through a pipe and fan and vents it outdoors, as in this sub-slab suction pipe.

Radon systems in Florida: our estimate and the wages behind it

An installed system is modeled at $875 to $1,975 per system, installed, from one national published range (1 counted) scaled by Florida's construction laborer wage ratio (0.87). It's an estimate, never a quote, and no Florida company price went into it.

Radon system trouble that shouldn't wait

Call right away
  • The system fan has stopped and a warning gauge or alarm shows it.
  • A vent pipe has cracked or come apart in the attic or crawl space.
  • A fan or its wiring is hot to the touch or smells of burning.
This can usually wait for a regular appointment
  • A fan that runs steadily with a gauge reading unchanged.
If you smell burning from the fan wiring or see smoke, switch off the breaker and call 911.

Before you hire for radon

  1. Ask which test result prompted the job and who ran the test.
  2. Ask where the vent will exit the house.
  3. Ask the building office whether the install needs a permit.

Permits for a radon system in Florida

Ask the building office about the fan wiring and the vent run at your address, because the $7,500 exemption doesn't cover electrical work.

DBPR has no foundation repair license category, so ask which state contractor license the company holds, look the number up on myfloridalicense.com and get its certificate of insurance before you sign anything.
