First-floor area is a common proxy for sub-slab communication work.
Typical active schedule
0.4 weeks
Post-mitigation testing windows and weather can affect completion dates.
Notes
Suction field
Communication test
Multiple suction points may be needed when communication is poor.
Pathway
Perimeter water
Design must protect against flooding and maintain depressurization goals.
Barrier
Under-membrane
Often pairs with encapsulation and conditioning work.
Leakage
Short-circuiting
Large openings can bypass the suction field—sealup matters.
Routing
Flashing detail
Discharge height and location follow standards and local rules.
Proof
Retest window
Closed-building conditions affect test validity—plan with your mitigator.

The calculator applies illustrative base bands by mitigation approach and foundation type, scales with footprint, adds sealing and electrical allowances, and applies a regional labor multiplier. The total is split across fan and materials, installation labor, and permits or fees. Diagnostic testing, multiple suction points, and interior finish protection are not itemized separately.
Core ≈ system band × foundation factor × footprint+ sealing + electrical; × regionUse results for budgeting—confirm with a certified radon mitigator and local codes.
Suction point, pipe routing, and discharge termination must meet standards
