Radon Fan Cost: Typical Prices, Ranges, and What Affects Price 2026

Typical buyers pay $350-$1,200 for a radon fan unit and $800-$2,500 total installed for a single-family home; the main cost drivers are fan capacity, installation complexity, and whether a new pipe and slab/soil work are needed. This article explains radon fan cost and the installation pricing readers will see on contractor quotes.

Item	Low	Average	High	Notes
Fan Only (basic inline)	$350	$600	$1,100	60-120 CFM; plastic housing
Typical Installed System	$800	$1,600	$2,500	Single-story slab, easy access
Complex Install (multi-level/soil)	$1,500	$3,000	$5,500	Basement + crawlspace + long runs
Permits & Testing	$50	$200	$700	Post-install test, local permit

Typical Radon Fan Prices for a Whole-House System

Buyers replacing only the fan typically pay $350-$1,100 for the unit; full system installs run $800-$2,500 for straightforward slab depressurization on a 1,200-2,000 sq ft single-family home. Average installed pricing assumes 60-100 CFM fan, one short vertical pipe run, and normal access to attic or exterior wall.

Assumptions: Midwest labor rates, standard PVC pipe, single-slab house.

Breakdown of a Radon Mitigation Quote

Materials	Labor	Equipment	Permits	Overhead
$75-$350 (pipe, fittings, sealant)	$300-$1,200 (3-10 hours)	$350-$1,100 (fan, vent cap)	$0-$300 (local)	$100-$500 (contractor markup)

Materials+Labor+Equipment typically compose the bulk of a quote; permits and overhead add the rest.

Site and Fan Specifications That Change the Final Quote

CFM rating, run length, and house type change price: 60-100 CFM fans fit most homes; 100-200 CFM for large houses or multi-level systems cost 25%-80% more for the unit and may double labor. Long horizontal runs (>30 linear ft), multiple suction points, or thick concrete slabs add $300-$2,000 to the total.

Examples: >30 lf run increases material+labor; >120 CFM fan adds cost and may require conduit.

Practical Ways To Lower Radon Fan Price on an Install

Choose a standard 60-100 CFM fan when testing shows it’s sufficient; prepare the work area and seal visible slab cracks before the crew arrives; get 3 quotes and schedule during slow seasons. Saving moves: prepare access, accept a simple exterior-mounted fan, and avoid decorative routing that requires drywall repair.

Tip: Bundling radon testing with mitigation may reduce testing fees.

How Prices Vary Across U.S. Regions and Market Types

Expect 10%-30% higher labor and overhead in urban Northeast and West Coast markets versus Midwest and South; remote/rural areas may add travel fees of $75-$300. Regional deltas: Midwest baseline, Northeast/West Coast +15%-30%, Rural +5%-20% for travel.

Assumptions: Comparable materials and identical system scope.

Installation Time, Crew Size, and Typical Labor Rates

Most installs take 2-8 hours for a single suction point; complex systems can take 1-3 days. Labor rates commonly run $75-$125 per hour; small crews (1-2 techs) handle standard installs, while large jobs use 3-4 crew members. Plan on 3-10 labor hours for typical installs and 10-24 hours for complex multi-point systems.

Assumptions: Licensed mitigation contractor, normal site access.

Common Add-Ons, Removal Fees, and Permit Costs That Affect Price

Item	Low	Average	High
Post-install radon test	$50	$150	$300
Electrical hookup / conduit	$75	$200	$600
Old fan removal & disposal	$0	$50	$200
Permit or inspection	$0	$75	$400

Include testing and local permit fees in budget planning, as they commonly add $100-$500 to a standard install.

Real-World Quote Examples With Specs and Totals

Example A: Basic replacement — 80 CFM inline fan, attic mount, 10 lf pipe, 3 labor hours: $350 fan + $300 labor + $75 materials = $725. Example B: Whole-house install — 100 CFM, exterior mounted, 40 lf runs, slab patching: $800 fan + $900 labor + $200 materials + $150 permits = $2,050.

Example C: Complex multi-point — basement and crawlspace suction, 150 CFM fan, 18 labor hours: $1,100 fan + $2,000 labor + $400 materials + $200 permits = $3,700.
