Typical Installed Price For A Sub-Slab Radon System
Most U.S. single-family homes with concrete slabs require active sub-slab depressurization. Typical total price ranges are $800-$2,500; averages cluster at $1,200-$1,800 for standard 1,200–2,000 sq ft homes with one suction point.
Expect $150-$500 for the fan plus $300-$1,200 for labor and $100-$400 for materials on a basic sub-slab job. Assumptions: Midwest labor rates, single-level slab, normal access.
Line-Item Cost Breakdown For A Radon Quote
| Cost Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials (PVC, sealants, caps) | $100 | $200-$350 | $600 | Per piping run and seals |
| Labor | $250 | $500-$1,200 | $1,800 | Typical 4-12 hours |
| Equipment (fan) | $150 | $250-$400 | $600 | Inline radon-rated fan |
| Permits | $0 | $0-$150 | $300 | Local permit rules vary |
| Accessories (manometer, caps, vent stacks) | $50 | $75-$150 | $300 | Includes warning labels and mounts |
| Contingency | $50 | $100-$300 | $600 | Hidden issues, long runs |
The sum of these parts produces the quoted total; homeowners should compare each line, not only the bottom line.
How Foundation Type and Number Of Suction Points Drive Price
Foundation condition is the single biggest variable: poured slab, block foundation, and crawlspace all change scope. Adding suction points increases material and labor costs by $125-$350 each.
Examples: single suction point for a small slab $800-$1,200; 2–3 suction points for larger slabs or block foundations $1,400-$3,000.

Site Conditions That Raise A Quote: Access, Depth, And Floor Coverings
Limited access, finished basements, or thick floor coverings increase time and difficulty. If installers must cut and repair slab or remove hardwood, expect 15%-50% higher labor and repair charges.
Numeric thresholds: finished basement floor repair adds $300-$1,200; long horizontal runs over 20 linear ft add $100-$400.
Practical Ways To Reduce Radon System Price Before Quoting
Control scope: clear workspace, move furniture, and reveal concrete for easy access; choose standard fan locations that avoid costly roof penetrations. Get three written quotes and request itemized invoices.
Small savings: doing basic prep and choosing interior vent exits can cut labor by $75-$300 on many jobs.
Regional Price Differences And What To Expect In Major U.S. Markets
Prices vary by market: expect +10%–30% in high-cost metro areas and -5%–15% in low-cost rural areas. Example deltas: Northeast and West Coast are typically 15%-30% higher than Midwest averages.
Estimate adjustments: if Midwest avg $1,400, expect $1,600-$1,820 in higher-cost metros and $1,200-$1,330 in lower-cost regions.

Typical Job Time, Crew Size, And Minimum Charges
Most residential installs take 2–8 hours with a 1-2 person crew; complex jobs take 10–16 hours. Expect minimum service calls or small-job minimums of $300-$600 in many areas.
Hourly labor rates usually range $75-$125 per hour per tech; long weekday or emergency calls may incur higher rates.
Three Real-World Quote Examples With Specs and Totals
| Example | Specs | Labor Hours | Per-Unit Rates | Total |
|---|---|---|---|---|
| Basic Slab Home | 1 suction, 1 fan, short vent | 4 | Fan $250, Labor $75/hr | $850-$1,050 |
| Finished Basement, 2-Point System | 2 suction, patching, exterior vent | 8 | Fan $325, Labor $90/hr | $1,650-$2,200 |
| Block Foundation, Multiple Runs | 3 suction, long horizontal runs | 12 | Fan $400, Labor $100/hr | $2,400-$3,500 |
These examples show how fan choice, labor hours, and sealing/repair combine to produce the final quoted price.
