Radon System Cost, Value & Comparisons
Short Answer (Up Front — No Teasing)
You likely just searched something along the lines of, “what does radon mitigation cost” so lets get that answered right away before getting into the ‘meat and potatoes’. In Pennsylvania, most professionally designed radon mitigation systems typically cost between $1,200 and $2,500, depending on the home’s construction, radon levels, and system complexity. Some homes may fall below or above that range, but this is where the majority land.
The key thing to understand is that radon mitigation is not a one-size-fits-all service, and price alone should never be the deciding factor.
Why Homeowners Ask This Question So Often
We hear this question almost every day—and for good reason. How much does radon mitigation cost is likely the first thing that comes to mind once you’ve learned that your radon levels are elevated.
Homeowners are often:
- Buying or selling a home
- Receiving a radon test result for the first time
- Comparing multiple mitigation quotes
- Seeing wildly different prices online
Unfortunately, many radon mitigation websites avoid talking about cost altogether, which creates confusion and mistrust. Our goal here is to explain what actually affects price so you can make an informed decision.
The Honest Truth About Radon Mitigation Cost
Radon mitigation pricing isn’t arbitrary. It’s based on:
- The age of your home which is a predictor if sub-slab gravel exists
- How many potential radon sources exist and can they be treated with a single system.
- Are the initial radon levels extremely high
- Are there finished areas to avoid exposed piping
- How difficult is a crawl space to access & work in
A properly designed system must:
- Reduce radon reliably regardless of season
- Minimize total operating cost by not wasting conditioned air
- Be durable, quiet, and visually appropriate for the structure
- Meet Pennsylvania DEP guidelines
Cheaper systems often skip design considerations. More expensive systems usually reflect added complexity—not upselling.
What Factors Affect the Cost of Radon Mitigation?
Here are the main variables that influence price:
1. Foundation Type
- Basement
- Slab-on-grade
- Crawlspace
- Exposed soil/gravel? Vapor barrier installation can add $4-6 per sqft
- Superior Walls pre-cast foundation
- Combination foundations i.e. additions
Each requires a different mitigation approach.
2. Initial Radon Levels
Higher radon levels may require:
- Identifying & treating radon sources beyond just the basement slab
- Designing a system for higher airflow requirements where more permeable geology exists
- Advanced diagnostics to evaluate system performance if post-mitigation results are still elevated after the initial radon system installation
3. Home Size & Layout
Larger or multi-level homes may need:
- Multiple suction points
- Longer piping runs
- Larger fans
- More complex airflow management
4. System Design Complexity
Design considerations include:
- Pipe routing aesthetics
- Electrical access
- Exterior fan & discharge location
- Noise and vibration control
5. Local Codes & Best Practices
Professional systems are designed to meet:
- Pennsylvania DEP Radon Mitigation Standards
- Building & electrical code requirements
- Some municipalities require a building permit and/or electrical permit
Compliance and quality matter.
Pros and Limitations of Radon Mitigation
Pros
- Highly effective when properly designed
- Permanent solution
- Improves indoor air quality
- Adds confidence during resale
Limitations
- Not a “plug-and-play” install
- Results depend on proper design
- Some visual impact (which can usually be minimized)
Not all radon systems are equal—well-designed systems consistently achieve excellent results.
DIY vs Professional Radon Mitigation: Cost Comparison
DIY Systems
Lower upfront cost, but:
- Often underperform
- Rarely meet standards
- Can create new airflow issues
- May complicate real estate transactions
Professional Systems
Higher upfront investment, but:
- Engineered for the home
- Tested for performance
- Designed to last
- Supported by experience and accountability
For most homeowners, professional mitigation is the safer long-term choice.
Is Radon Mitigation Worth the Cost?
For homes with elevated radon levels, mitigation is generally considered a high-value investment because it:
- Reduces a known health risk
- Protects long-term occupancy
- Prevents future real estate complications
That said, not every home needs mitigation. Testing and proper interpretation always come first.
Why We Don’t Design Systems Just to “Get below 4.0”
The EPA & PA DEP action level of 4.0 pCi/L was established as a practical guideline, not a safe threshold. There is no known safe level of radon exposure.
At Integra Environmental, our goal is to design systems that achieve levels as low as reasonably achievable, not just barely compliant.
Results matter.
What We Recommend Homeowners Do Next
- Test your home using an appropriate method
- Request a FREE Radon test kit
- Purchase a homeowner digital radon monitor. We recommend the Ecosense brand (5% referral discount applied at checkout)
- Review the results with a qualified professional
- Ask questions about design—not just price
- Make a decision based on long-term system performance
No pressure. Just good information.
