Our professional test in York is $150 to $250, which is separate from [radon mitigation system pricing](/radon-mitigation-cost/). A kit is fine for a first check. A professional test is the usual choice for home sales, because it uses calibrated equipment and a certified tester. ## How much does a radon test cost? There are two main paths, and the price gap between them is mostly about who does the work and how the result will be used. **Home test kits.** The PA DEP says an easy-to-use home test kit costs about $20 to $30 at hardware and home improvement stores. Some kits include the lab fee and return postage. Others charge the lab fee separately, so read the box. HomeGuide lists DIY kits at about $10 to $30. **Professional radon tests.** National cost guides put professional testing at roughly $125 to $400 (HomeGuide) and up to $150 to $700 (Angi), depending on the device, the building size and how fast you need results. Our price is $150 to $250 for a standard home test in York. In Pennsylvania, anyone who tests radon for someone else must be certified by the PA DEP. That rule is part of what you are paying for with a professional test. ## What a professional test includes A professional test costs more because it covers more than the device. Here is what you should expect: - **Placement.** The tester sets the device in the lowest lived-in level, away from drafts, windows, sumps and exterior walls. - **Calibrated equipment.** Most professional tests use a continuous radon monitor that records hourly readings. - **Tamper checks.** Many monitors log movement, temperature and humidity, which matters in a home sale. - **Retrieval and report.** You get a written report with the average result and the hourly data. - **Closed-house guidance.** The tester explains how to keep windows and doors closed during the test period. A home kit relies on you to place it correctly, follow the timing, and mail it to the lab on time. Mistakes in any of those steps can make the result less useful. ## Which test do you need? The right test depends on why you are testing. ### For your own peace of mind A short-term home kit is a fine first step. If the result is 4.0 pCi/L or higher, EPA recommends a follow-up test. If both results are high, or the average is at or above the EPA action level of 4.0 pCi/L, plan to fix the home. EPA also says to consider fixing between 2 and 4 pCi/L. ### For a home sale Buyers and sellers in York usually use a professional test. The timeline is tight, the result goes into the deal, and both sides want a certified tester. If the result is high, the next question is mitigation cost and timing. Our page on [radon testing in York, PA](/services/radon-testing/) explains how we schedule around inspection contingencies. ### After a mitigation system goes in EPA guidance is to run a post-mitigation test no sooner than 24 hours after the system starts and within 30 days. Our clearance test is included with every system we install, so you do not pay for it separately. ### For an older system If you have an existing system, test every couple of years and after major renovations. A rising number often points to a worn fan. Our guide to [radon fan replacement cost](/radon-guide/radon-fan-replacement-cost/) explains what that repair usually involves. ## Hidden costs to watch for Some test prices look low but leave things out. Check for these extra charges: - Lab fees that are not included in the kit price - Return shipping - Rush fees for results inside a closing window - Trip charges for a second visit - A separate charge for a written report The PA DEP also offers some free test kits in limited cases, such as a free confirmation kit when a screening test shows very high levels, and coupons given to parents of newborns. Check the [PA DEP radon in the home page](https://www.pa.gov/agencies/dep/programs-and-services/radiation-protection/radon-division/radon-in-the-home) for current details. ## Why York homes should test York County is in [EPA Radon Zone 1](https://www.epa.gov/radon/epa-map-radon-zones-and-supplemental-information), the group of counties with the highest radon potential. Radon has no smell, no color and no immediate symptoms. A test is the only way to know your level. EPA estimates radon causes about 21,000 lung cancer deaths a year in the U.S., and it is the leading cause among non-smokers. A neighbor's result does not tell you yours. Two houses on the same street can test very differently because of soil, foundation and how the house is built. ## Key takeaways - Home kits cost about $20 to $30, sometimes plus lab fees, according to PA DEP. - Professional tests cost more but use calibrated monitors and a DEP-certified tester. Our price is $150 to $250. - Use a professional test for home sales. - Retest after a mitigation system goes in. We include that clearance test with every install. ## Frequently Asked Questions ### Is a home radon kit accurate? A home kit can be accurate if you follow the directions exactly. Place it in the right spot, keep closed-house conditions, and mail it on time. Errors in those steps are the most common cause of bad results. ### Do I need to test again after mitigation? Yes. A post-mitigation test confirms the system works. After that, testing every couple of years is a good habit. ## Next step If your test came back high, the next question is what a fix will cost.
