State-of-the-Art Radon Mitigation – RadonSeal
RadonSeal Deep-Penetrating Concrete Sealer penetrates deep inside concrete, reacts with chemicals harmful to the concrete, expands into even microscopic pores, and hardens into a non-reactive, insoluble mineral. The result is a denser concrete that is permanently sealed against water seepage, water vapor, and radon gas. Unlike concrete paints, RadonSeal does not color the concrete and leaves no film that could peel.
This is the most advanced radon mitigation method, yet affordable and user-friendly. The resulting radon reduction is not limited by the size of mechanical equipment, the permeability of soil, or fluctuating moisture in the soil. Unlike mechanical mitigation methods, it does not depend on the reliability of hardware or the power grid. The seal cannot deteriorate over time and is permanent!
Quick and Easy Do-It-Yourself Application
RadonSeal is sprayed on bare, unpainted concrete by a common garden sprayer. The application is much faster than painting and safe. There are no noxious fumes. RadonSeal is an environment-friendly, water-based sealer – nonflammable, non-toxic, with zero VOCs. It works indoors and outdoors, on poured concrete or concrete blocks, basement floors and walls, foundation slabs, and crawlspace floors.
Afterwards, you have to seal or caulk all openings, gaps, or cracks as required by all radon mitigation methods.
Big Savings to Homeowners
Compared to fan-suction radon mitigation systems, RadonSeal saves you hundreds of dollars on the initial cost and continues to deliver savings every year:
| Typical Savings on Radon Mitigation | |||
|---|---|---|---|
| Method | Fan-Based Mitigation | RadonSeal Mitigation | Est’d Savings |
| Method | Fan-Based Mitigation | RadonSeal Mitigation | Est’d Savings |
| Installation Cost | EPA: $ 1,200 | avg. $ 550 | $ 650 |
| Energy Losses, Electricity Cost | $ 225-500/year | $ 0/year | $ 360/year |
| Operating Expenses over 10 years | avg. $ 3,600 | $ 0 | $ 3,600 |
| 10-Year Savings to the Homeowner | $ 4,250 | ||
In addition, you will have to regularly replace the fan, which is usually guaranteed for up to 3 years (US EPA).

Save $100’s on Installation!
EPA: “The average house costs about $1,200 for a contractor to fix, although this can range from about $800 to about $2,500, depending on the characteristics of the house and the method used.”
RadonSeal can save you hundreds of dollars – the typical cost is only $400-$700.
Operating Costs of Radon Mitigation Systems
EPA: “Systems that use fans are more effective in reducing radon levels; however, they will increase your electric bill. Remember, the fan should never be turned off; it must run continuously for the system to work correctly. A warning device must be installed to alert you if the system stops working properly.”
RadonSeal has ZERO operating costs.
Save $100’s in Energy Losses
EPA: “Most types of radon reduction systems cause some loss of heated or air conditioned air, which could increase your utility bills. How much your utility bills will be affected depends on the climate you live in, what kind of reduction system you select, and how your house is built.”
Energy losses in conditioned air are much higher than the cost of electricity. There are ZERO energy losses with RadonSeal.
If you already have a fan-based radon mitigation system, RadonSeal will reduce its energy losses by stopping the suction of treated air through the slab into the radon fan.
Maintenance Costs of Radon Mitigation Systems
EPA: “Radon reduction systems need occasional maintenance. Warning device should be checked on a regular basis to make sure the system is working correctly. Fans may need to be repaired or replaced (manufacturer warranties usually do to exceed three years). Replacing a fan will cost around $250. Testing radon level at least every two years will confirm that the fan is still performing well. The filters in an Heat Recovery Ventilation system require periodic cleaning and should be changed twice a year, and the ventilator should be checked annually by a professional to make sure the air flow remains properly balanced.”
RadonSeal has ZERO maintenance costs. Re-application is not needed. The seal is permanent.
RadonSeal Delivers More than Radon Mitigation
At a cost comparable to painting the concrete, RadonSeal delivers much more than radon remediation:
- waterproofs concrete, stop wicking of water,
- damp-proofs concrete against water vapor transmission causing damp basements,
- neutralizes alkalis, reduces efflorescence (“white powder”),
- prevents molds, mildew, and musty odors,
- strengthens concrete, reduces cracking, spalling, and dusting,
- protects paints, tile adhesive, or carpeting against alkalis from the concrete,
- deep-cleans, purges dirt, and seals the concrete against spills.
Reduce Radon to a Practical Minimum!
There is no “safe” radon level! (EPA) Radon gas decays into minute radioactive particles, which get trapped in our lungs. It is the leading cause of lung cancer deaths among non-smokers and the second leading cause among smokers. (The Surgeon General) Radon in homes causes about 21,000 lung cancer deaths in the U.S. each year.
The danger is proportional to radon concentration: Reducing the radon level in home by 50% (or 90%) lowers the cancer risk to the family by 50% (or 90%). Radon mitigation is particularly important for families with children. Whatever your current radon level, reduce it to a minimum. Provide a healthy home for your family!
