The most popular radon test kits in the U.S. available at unbeatable prices! Made by the world’s largest producer of radon test kits. Rated #1 by a leading consumer product testing group. There are no hidden charges – no $20.00 Test Fees or a $15.00 Report Fee! Free shipping both ways! If you are lucky and your radon level comes out below 2 pCi/L, it has just cost you the nominal price of the kit and you have saved $15.00 or more.
You can even get one air test kit for free! State programs providing free radon testing kits to homeowners have all but disappeared. We can help a bit. If your radon level is higher and you decide within two months to buy RadonSeal Penetrating Concrete Sealer to seal your basement against radon and moisture, the cost of the test kit is on us. Just send us the Refund Coupon or phone us and we will issue a $14.95 rebate to your card. Limit – one free short-term kit per customer!
The short-term air test kits provide quick results. But since radon levels fluctuate wildly, long-term test kits will give you much more accurate results. If you have well water, test the radon level in the water too because it can release lots of radon gas into the indoor air.

Free shipping by First Class mail in the US. Sorry, no shipping to New Jersey.
You will have the option to select shipping by Priority Mail or mail to Canada.
Everything is included!
- FREE shipping by First Class mail throughout the US.
- FREE return mailer for air test kits with postage (the US only).
- FREE laboratory analysis (save $15 to $25).

There are NO HIDDEN CHARGES for testing, test reports, shipping, or otherwise. Compare that to radon kits sold in big-box stores: $9.97 per kit plus an extra $25 for testing, or $12.97 per kit plus an extra $10 for rush processing within 10 days which is “recommended” for valid results. (The half-life of radon is 3.8 days – after 10 days the results are not accurate.)
How to get a radon test kit for free!
You can get an automatic $14.95 rebate if you purchase at least one 5-gal. pail of RadonSeal Deep-Penetrating Concrete Sealer within two months after purchasing the radon test kit(s). RadonSeal seals concrete basement floors and walls permanently against radon gas infiltration, water seepage, and water vapor. Compared to a fan-based radon mitigation system, sealing your basement with RadonSeal will save you over $1,000 on installation and operation. And it does more – it also seals against water and preserves the concrete.
If you purchase both on the same day, the rebate is issued automatically within a day. Or you can send us the Refund Coupon or email us as a reminder. Limit – one free kit per customer!
The fastest turn-around time!
- Time is of the essence in the real estate business. Our test kits are shipped out by First Class mail the same or next business day. For faster delivery of the test kits to you in the U.S., you can choose the Priority Mail option at $6.10 per kit.
- To speed things up, you can return the test kits to the test laboratory by Priority Mail or by courier. This is strongly recommended for Canadian customers. Every day of delay in returning the kit to the lab reduces the accuracy of the test results.
- “Same day” results: The kits are normally processed the same day as they arrive in the test laboratory. The certified test report is posted online and mailed by e-mail and first-class mail the same day.
Depending on your shipping options, you may get the results in one or two weeks after your order. Receiving the test results back in 3 or 4 weeks is common for other radon test kits.
Are short-term test kits worth it?
Radon levels fluctuate wildly and a short-term test is just a snapshot. Some argue that short-term test kits are worthless. Since radon levels fluctuate depending on weather and season, long-term test kits provide much more reliable results. Find out more at short-term vs long-term radon test kits and what a homeowner should do.
When using short-term radon test kits, EPA recommends two side-by-side test kits for each location for the most reliable results.
Radon gas causes lung cancer
Radon is an invisible radioactive gas produced by most rocks and soils. It is a single-atom gas whose atoms easily penetrate through openings in foundations, pores in concrete, drywall, paints or surface sealers, and even most plastics. Basements have the highest concentrations.
Radon gas is a very potent carcinogen and children are particularly susceptible. Among non-smokers, radon is the leading cause of lung cancer which is the #1 killer among all cancers.
Radon testing of all homes
Elevated radon levels have been found in every state. EPA recommends radon testing of all homes. Radon testing is essential before putting a house on the market to allow time for installing radon mitigation and before buying a house or before finishing the basement.
If you have a private well, test the radon level in your water with the radon-in-water test kit. Showering, cooking, dishwashers, and washing machines release radon gas into the air. As a rule of thumb, each 10,000 pCi/L in water contributes 1 pCi/L to indoor air.
Repeat the radon test every year or two!
Concrete becomes more porous over time, joints or cracks open up, and underground flows of radon shift. Whether or not you have a radon mitigation system, your radon level might increase dramatically. Radon test results are considered invalid after two years. EPA recommends that homeowners repeat the radon test regularly.
Test the radon level in your home about once a year! Radon test kits are inexpensive and your family’s health is at stake.
There is no “safe” radon level!
EPA’s recommendations to homeowners:
- If your radon level is 4 pCi/L or higher, fix your home.
- If your radon level is 2 pCi/L or higher, consider fixing your home.
However, EPA warns that there is no “safe” radon level! The Radon Act has set the target radon level in homes much lower at 0.4 pCi/L.
If you just settle for 4 pCi/L, your home will be more radioactive than 94% of U.S. homes. The lung cancer risk to each member of the family is equivalent to smoking 8-10 cigarettes a day.
The vast majority of radon-induced lung cancers occur in homes with radon concentrations below the 4 pCi/L “Action Level.”
Your radon mitigation options
Reduce radon in your home to a “reasonably achievable minimum”! You can get a fan-based radon mitigation system, which exhausts the heavy radon gas above your roof.
Or you can avoid the noisy radon fan and unsightly piping by sealing the basement against radon with the RadonSeal radon mitigation method. It saves lots of money on installation and operation and it does not depend on the reliability of equipment or the power grid.
