SERVICE OVERVIEW
Crawl space radon sealing is one of the most effective ways to stop radon gas from entering your home through below-ground foundation areas. Your crawl space is often where radon enters first, and sealing it properly can dramatically reduce radon levels throughout your entire house.
In Central PA, where radon naturally occurs in our soil and bedrock, crawl space sealing is a smart investment for homeowners who want real protection. PA Radon Pros specializes in professional crawl space sealing that works fast and lasts for years.
WHY THIS SERVICE MATTERS
Radon is a colorless, odorless radioactive gas that seeps up from the ground into homes and buildings. Crawl spaces with exposed soil or cracks are direct pathways for radon to enter your living spaces. Long-term radon exposure is linked to serious health risks, including lung cancer.
Central PA’s geology makes radon a real concern for many homes. The sooner you seal your crawl space, the sooner you reduce your family’s exposure and improve your home’s air quality.
Professional crawl space sealing gives you peace of mind and protects your family’s health. It also increases your home’s value and resale appeal—especially important if you’re planning to sell in the near future.
OUR SIMPLE, PROVEN PROCESS
Step 1 — Assessment / Inspection: We examine your crawl space for radon entry points, soil cracks, and moisture issues. Our certified team identifies the best sealing approach for your specific situation.
Step 2 — Service Design or Planning: We explain our findings and recommend a custom sealing plan tailored to your crawl space. We’re transparent about costs and timelines so you know exactly what to expect.
Step 3 — Professional Service Delivery: Our trained technicians seal cracks, cover exposed soil, and install vapor barriers using EPA-approved materials and methods. Every job is done with precision and care.
Step 4 — Verification / Final Check: We test to confirm that radon levels have dropped and that your sealing is effective. You receive documentation and clear results.
Step 5 — Long-Term Value or Maintenance: We provide guidance on maintaining your crawl space and recommend follow-up testing to ensure your system continues protecting your home.

Get A Free QuoteHow long does the sealing process take?
Most crawl space sealing jobs are completed in one to three days, depending on the complexity of your crawl space. We’ll give you a clear timeline during your assessment so you know exactly when we’ll be working.
How often do I need to reseal my crawl space?
A properly installed seal lasts for years with minimal maintenance. We recommend follow-up radon testing every two to three years to ensure your system is still working effectively. We’ll help you track this schedule.
Will sealing my crawl space increase my home's value?
Yes. Addressing radon makes your home more attractive to buyers and inspectors, especially if you’re planning to sell soon. A sealed crawl space backed by test results gives buyers confidence in your home’s safety and air quality.
Is radon really that serious of a health concern?
Yes. Radon is a colorless, odorless radioactive gas, and long-term exposure is linked to serious health risks including lung cancer. It’s the second leading cause of lung cancer after smoking, which is why sealing your crawl space is important for your family’s health.
Do I need to have radon tested before calling you?
It’s helpful if you’ve already tested and know your radon levels, but not required. If you haven’t tested yet, we can recommend testing as part of our assessment. High radon levels above 2.0 pCi/L indicate you need mitigation.
What happens after my crawl space is sealed?
We provide guidance on maintaining your crawl space and recommend follow-up radon testing in the future to ensure your sealing continues to protect your home. You’ll have peace of mind knowing your family is protected.
Why should I choose PA Radon Pros over other companies?

What if I'm buying a home and need radon mitigation before closing?
We understand the time pressure in real estate transactions. Let us know your closing timeline, and we’ll work to schedule your inspection and sealing quickly so you can meet your purchase contingency requirements.
How do I know the sealing actually worked?
We test your radon levels after sealing is complete to verify the reduction. You’ll receive clear documentation showing the before and after results so you can see the real impact of our work.
Do I need to prepare anything before the work begins?
No special preparation is required. Just make sure we have clear access to your crawl space. If you have items stored down there, let us know and we can work around them or you can clear a path.
How soon can you come out to inspect my crawl space?
We work to schedule inspections quickly so you can get answers fast. Call us or fill out our contact form, and we’ll find an appointment that works for your schedule.
Is crawl space radon sealing safe?
Yes, completely safe. We use EPA-approved materials and methods that are proven to reduce radon safely and effectively. Our certified technicians follow strict safety standards, and the sealing process poses no risk to you or your family.
How much does crawl space radon sealing cost?
The cost depends on your crawl space size, the number of entry points, and the sealing approach needed. We provide a custom quote after inspecting your home, and we always explain costs upfront with no surprises. We offer competitive pricing and flexible options to fit your budget.
