Radon Testing in Central Pennsylvania
Testing is the first step in the radon story, and it is the only way to know whether your home needs anything done at all. Central PA Radon Pros connects homeowners in Dauphin, Cumberland, Lancaster, and York counties with independent, licensed contractors who are certified by the Pennsylvania DEP to measure indoor radon. The reading you get back tells you exactly where you stand against the EPA action level. Quotes are free and come with no obligation.
Why testing matters here
You cannot see, smell, or taste radon, so a measurement is the only signal you get. In this region that signal matters more than most places: the EPA places Dauphin, Cumberland, Lancaster, and York counties in Zone 1, its highest radon potential category, and the Pennsylvania DEP estimates about 40 percent of homes statewide test above the action level. A test turns that background risk into a number you can act on.
Types of radon test
Short-term tests (2 to 90 days)
Charcoal canisters and continuous radon monitors give you a reading in a matter of days. They are the quickest way to find out whether your home is above the action level, and they are the standard choice when a home sale is on a clock.
Long-term tests (more than 90 days)
Alpha-track and electret detectors sit in the home for months and report a year-round average. Because radon levels swing with the seasons, a long-term result is the truest picture of what your household actually breathes.
Continuous radon monitors
The professional-grade instruments a certified tester brings to a real estate measurement. They log radon hour by hour and flag interference, which is why they are common when a reading has to hold up in a transaction.
When to test or retest
- You have never tested, or your last test was more than two years ago
- You just installed a mitigation system and need to confirm the level dropped
- You finished a renovation, foundation repair, or a change to how the home is heated
- You are buying or selling a home and need a documented reading
The EPA recommends retesting every two years even after a home has been cleared once, because levels shift over time. If a reading comes back at or above the action level, the next move is a radon mitigation system.
What moves the cost of a test
Testing is the least expensive step in the process, and the price turns on a few choices rather than a flat rate:
- Short-term versus long-term measurement
- A do-it-yourself test kit versus a certified professional placement
- Whether the reading is for your own information or for a real estate transaction
- The number of levels or units that need separate measurement
A certified contractor gives you a free quote for the measurement your situation calls for. If the test is tied to a home sale, see radon for real estate transactions for how the timing works.
Verify Your Contractor's PA DEP Certification
Under Pennsylvania's Radon Certification Act of 1987, anyone who performs radon testing, mitigation, or laboratory analysis for hire must be certified by the Department of Environmental Protection. Certification is the state's baseline for who may do this work, so confirm it yourself before you sign anything. Every contractor you are matched with through this site is asked to hold current DEP certification, and you can check any name against the official state records below.
Three questions to ask before you hire
- May I see your current DEP certification number?
- Is the person doing the work the certified individual?
- Will you retest after installation to confirm the reading dropped?

What it costs, and what happens after you send the form
- What does it cost?
- The DEP fact sheet puts a residential mitigation system at about $800 to $1,200, but that is not this page's number. Testing is the least expensive step, and a commercial or school building is priced by its own size and layout, so the certified professional who looks at the property is the honest source of that figure. Either way it is a range to plan against, not a quote and not our price.
- How fast will someone get back to me?
- Calls and form submissions reach Compass Camper LLC directly. We read the request and pass it to an independent DEP-certified local radon professional, usually within about an hour during the day. They then contact you to look at the property and give you a free written quote on their own schedule.
- What work is covered?
- Radon mitigation, testing, radon at a home sale, and commercial and school radon.
Only the independent DEP-certified contractor you are matched with can price your actual property. Compass Camper LLC does not perform radon work and does not quote it.
Radon Testing Questions
What radon level means my home needs action?
The EPA recommends fixing your home when the radon level reaches 4 picocuries per liter (pCi/L) and suggests considering action between 2 and 4 pCi/L. The EPA also reports that radon is the leading cause of lung cancer among people who have never smoked, so a reading near the action level is worth taking seriously.
How long does a radon test take in Central Pennsylvania?
A short-term test runs from 2 to 90 days, and many are read in about 2 to 7 days. A long-term test stays in place for more than 90 days to capture a year-round average. The contractor you are matched with recommends the right length for your situation, especially if you are working against a settlement date.
Do I need a certified tester, or can I use a home kit?
A home test kit can tell you whether you have a problem. For a real estate transaction, or any reading you need to be defensible, Pennsylvania requires anyone who tests for hire to be certified by the DEP under the Radon Certification Act. A certified tester follows closed-building protocols and uses tamper-resistant monitors so the result holds up.
How should the home be set up during a short-term test?
Keep windows and exterior doors closed for 12 hours before the test and for its full duration, and run the home normally otherwise. The device belongs on the lowest level you regularly use, away from drafts, exterior walls, and high humidity. A certified tester handles this placement for you.
What happens if my test comes back high?
An elevated result does not mean anything is wrong with your home, only that soil gas is collecting inside. The next step is a mitigation system, which vents that gas before it enters your living space. You can read how those systems work on our radon mitigation page and request a free quote from a certified contractor.
