Radon Mitigation Proposal Template: Win Safer-Home Jobs Without Underpricing Diagnostics, Routing, Permits, and Post-Test Proof
A homeowner gets a radon test result back.
It says 6.8 pCi/L.
Now they want a price.
That sounds simple until you realize the job is not just "install a fan." A real radon mitigation proposal has to explain diagnostic testing, slab conditions, suction point placement, pipe routing, fan sizing, electrical work, permits, sealing limits, exterior appearance, and post-installation proof that the system actually reduced the reading.
If your proposal only says "radon system - $1,500," the homeowner compares you to the cheapest installer with PVC pipe and a fan in the truck.
Radon mitigation is a safety job, a diagnostic job, and a trust job. The customer is not buying plastic pipe. They are buying lower risk, a code-compliant system, a cleaner inspection report, and documented proof that the home is safer after you leave.
This guide gives you a complete radon mitigation proposal template, a 3-tier pricing structure, benchmark ranges, assumptions, exclusions, follow-up language, FAQ, and proposal wording that helps you protect margin without sounding like you are hiding behind technical jargon.
Why Radon Mitigation Proposals Lose
1. The diagnostic work is not valued. Pressure field extension testing, slab evaluation, crawl space review, and fan selection are real work. If the proposal does not explain them, the client assumes every contractor is installing the same system.
2. Pipe routing is treated like a detail. Interior route, exterior route, garage route, attic route, roof penetration, siding color, and visibility all affect labor and material cost.
3. Permits and electrical work are vague. Some jurisdictions require permits. Fans need proper power. If the proposal does not clarify who handles what, the customer assumes it is all included.
4. Post-test proof is missing. The client wants to know the system worked. A professional proposal should define the post-mitigation test method and timing.
5. There is only one price. One number forces the client into a lowest-bid comparison. Three options help them choose between compliant, quieter, cleaner, and better-documented outcomes.
What Every Radon Mitigation Proposal Needs
- Project summary with test result, property type, foundation type, and intended outcome
- Diagnostic scope covering visual inspection, suction point planning, pressure field testing when needed, and fan selection
- System design with pipe route, discharge location, fan location, and manometer placement
- Permits and electrical note so the client knows who is responsible for each regulated step
- Assumptions and exclusions for slab condition, hidden utilities, crawl spaces, finished areas, and cosmetic restoration
- Post-test proof with timing, test responsibility, and documentation language
- Three pricing options so the client can compare compliance, noise control, appearance, and follow-up support

Project Summary
Provide radon mitigation for a single-family home with basement foundation and recent radon test result of 6.8 pCi/L. Proposed work includes installation of an active sub-slab depressurization system designed to reduce indoor radon levels and provide visible system operation monitoring.
The final system design will be confirmed after on-site inspection of slab condition, utility locations, drain tile conditions, crawl space areas, and viable pipe routing options.
Scope of Work
| Phase | Included Work |
|---|---|
| Site assessment | Review radon result, inspect foundation type, identify suction point options, confirm routing path |
| Diagnostic planning | Evaluate slab penetrations, sump pit, crawl space, expansion joints, and pressure field conditions as needed |
| System installation | Core suction point, install PVC piping, mount radon fan, route discharge per applicable clearance requirements |
| Sealing | Seal accessible slab penetrations, sump lid gaps, cracks, and utility openings that materially affect system performance |
| Monitoring | Install U-tube manometer or visual indicator for system operation |
| Closeout | Label system, review operation basics, provide post-test instructions, and clean work area |
Pricing Options
| Option | Description | Price |
|---|---|---|
| Code-Compliant Standard System | Single suction point active system, exterior fan placement, standard PVC route, basic sealing, manometer, homeowner post-test guidance | $1,695 |
| Quiet Route + Proof Package | Standard system plus cleaner route planning, upgraded low-noise fan selection where appropriate, expanded accessible sealing, contractor-supplied post-test kit, and result review | $2,250 |
| Premium Low-Visibility System | Quiet Route package plus attic or garage route where feasible, weatherproof discharge detailing, expanded cosmetic planning, permit coordination allowance, and 12-month system check | $3,150 |
Recommended: Quiet Route + Proof Package. Best fit for homeowners who want the system to look clean, run quietly, and include documented confirmation after installation.
Timeline
| Step | Estimated Timing |
|---|---|
| Proposal approval and deposit | Day 0 |
| Permit submission, if required | 1-3 business days after approval |
| Installation scheduling | Typically 5-10 business days after approval or permit release |
| On-site installation | 1 working day for most standard systems |
| Post-mitigation radon test | Start after system has operated for at least 24 hours, commonly within 2-7 days |
| Result review and closeout | After test result is available |
Schedule may change based on permit timing, weather, electrical availability, hidden conditions, and route complexity.
Assumptions
- Pricing is based on one active sub-slab depressurization system for a standard residential foundation.
- Work area is accessible and free of stored items before installation.
- Standard concrete drilling conditions are present.
- Exterior route is available unless a premium interior, attic, or garage route is selected and confirmed feasible.
- Existing electrical service is adequate for fan connection by a qualified electrician where required.
- Accessible cracks and penetrations can be sealed without demolition or finish restoration.
- Post-test results depend on home conditions, foundation communication, weather, HVAC operation, and closed-house testing protocol.
Exclusions
Not included unless stated otherwise:
- Licensed electrical work, dedicated outlet installation, or panel work
- Permit fees above listed allowance
- Drywall, trim, flooring, siding, roofing, or paint restoration
- Concealed utility repair, plumbing rerouting, or drain tile repair
- Crawl space encapsulation or vapor barrier replacement unless listed in selected option
- Additional suction points required due to poor pressure field extension
- Radon in water testing or treatment
- Long-term continuous radon monitor rental unless listed separately
Post-Test Proof
After installation, the system should operate continuously for at least 24 hours before a short-term post-mitigation radon test is started. The test should follow closed-house conditions and be placed in the lowest lived-in level of the home.
For the Quiet Route + Proof Package and Premium Low-Visibility System, SafeAir Radon Solutions will provide a post-test kit, review the result, and provide a closeout summary for the homeowner's records.
If the post-test result remains at or above 4.0 pCi/L, we will review system operation and site conditions. Additional suction points, sealing, fan upgrades, or crawl space work may require a written change order if outside the approved scope.
Payment Terms
- 35% deposit due at proposal acceptance to reserve scheduling and materials
- 55% due upon substantial installation completion
- 10% due after post-test kit is delivered or closeout walkthrough is completed, whichever comes first
- Change orders must be approved in writing before additional billable work begins
Follow-Up Language
Thank you for the opportunity to provide this radon mitigation proposal. Based on the test result and foundation type, the priority is to install a system that reduces radon levels, runs reliably, and gives you proof after installation.
The Quiet Route + Proof Package is our recommended option because it balances cost, appearance, noise control, sealing, and post-test documentation. If you would like to move forward, reply with the selected option and we will confirm the installation date, access requirements, and any permit or electrical steps before work begins.

3-Tier Pricing Strategy for Radon Mitigation Contractors
Radon customers are usually worried, but they are also trying to understand why one bid is $1,200 and another is $3,000. Tiered pricing helps you separate a basic compliant system from a cleaner, quieter, better-documented installation.
| Tier | Best For | Typical Range |
|---|---|---|
| Basic / Code-Compliant Standard | Standard basement or slab-on-grade homes where a simple exterior route works | $1,200 - $1,900 |
| Standard / Quiet Route + Proof | Most homeowners who want better fan selection, cleaner routing, sealing, and post-test support | $1,900 - $2,700 |
| Premium / Low-Visibility System | Finished homes, HOA-sensitive exteriors, attic routes, garage routes, complex slabs, or stronger documentation needs | $2,700 - $4,500+ |
The middle option should be the package you would want installed in your own home: reliable, clean enough to be proud of, and documented after the work is done.
Radon Mitigation Pricing Benchmarks
| Service | Benchmark Range |
|---|---|
| Standard active sub-slab depressurization system | $1,200 - $2,000 |
| Multi-suction-point system | $2,000 - $3,500+ |
| Attic or garage route upgrade | $500 - $1,500+ |
| Crawl space vapor barrier and depressurization add-on | $1,500 - $5,000+ |
| Additional suction point after diagnostics | $350 - $900 each |
| Post-mitigation test kit and result review | $50 - $200 |
| Electrical outlet or fan power by electrician | separate line item |
Rule of thumb: if the proposal does not separate diagnostics, routing, sealing, fan selection, and proof, the homeowner assumes every radon system is the same pipe with a different sticker.
5 Mistakes Radon Contractors Make
1. Selling the fan instead of the result. The fan is a component. The client is buying lower radon levels and documentation that the system works.
2. Ignoring route difficulty. A short exterior route and a low-visibility attic route should not be priced like the same job.
3. Leaving electrical responsibility unclear. If the fan needs a new outlet, dedicated circuit, or licensed electrician, say that in the proposal.
4. Promising a number without conditions. A good system should reduce radon, but hidden slab conditions, crawl spaces, drain tile, and foundation communication affect results. Promise the process and follow-up, not magic.
5. Skipping the post-test conversation. Without post-test proof, the homeowner is left hoping the system worked. That is a weak closeout for a safety-driven job.
Radon Proposal FAQ
What radon level needs mitigation?
Many homeowners use 4.0 pCi/L as the action level for mitigation decisions. Some clients choose to mitigate lower results for peace of mind, especially when the home has finished basement living space, bedrooms, or long daily occupancy on the lowest level.
Can you guarantee the final radon number?
No contractor should promise an exact final number before installation and testing. A strong proposal should state the target outcome, explain the variables, and define the follow-up path if the first post-test result is still elevated.
Does the proposal include permits?
It should say exactly what is included. Some areas require permits or inspections for radon systems, exterior penetrations, electrical work, or roof routing. If permit fees are variable, include an allowance or list them as pass-through costs.
Who handles the electrical work?
Radon fans need safe power. If local rules require a licensed electrician, list electrical work as excluded or as a separate line item. Do not bury it in vague language.
When should the post-mitigation test happen?
The system should usually run for at least 24 hours before testing begins. Short-term tests commonly run 48 hours or longer, depending on the test device and instructions. The proposal should state who provides the test and who reviews the result.
What happens if the radon result is still high?
The contractor should inspect system operation, manometer reading, fan performance, route condition, and possible unsealed openings. If the approved scope was installed correctly but the home needs added suction points, crawl space work, or additional sealing, that should be handled by change order.
