York Radon Help helps homeowners understand radon results, learn how mitigation works, evaluate costs and contractor qualifications, and request help when they are ready to speak with a participating independent provider.

Pennsylvania provides radon testing, mitigation, and certification resources through the Pennsylvania Department of Environmental Protection (PA DEP), while the U.S. Environmental Protection Agency (EPA) provides national guidance on testing and reducing radon in homes.

If you already have a radon result—or you are trying to decide whether testing or mitigation should come next—start by understanding what the number means.

Understand Your Result

Understand Your Radon Result Before You Decide What Comes Next

Radon is measured in picocuries per liter of air (pCi/L).

EPA recommends taking action to fix a home when the radon level is 4 pCi/L or higher. EPA also notes that radon levels below 4 pCi/L still carry some risk and that homeowners may consider reducing levels between 2 and 4 pCi/L.

The number itself is only part of the picture.

It also helps to understand:

where the test was placed;
how long the test ran;
what type of test was used; and
whether the test conditions were appropriate.

A map, ZIP code, county statistic, or neighboring home's result cannot tell you the radon level inside your particular home. Testing is the way to determine the radon level in the home.

Connected Stages

Radon Testing and Mitigation Are Two Connected Stages

Testing tells you about the radon level in the home.

Mitigation is the process used to reduce elevated indoor radon.

Understanding which stage you are in can help you avoid jumping ahead—or paying for work before you understand the result you are acting on.

Stage One

Radon Testing

Radon testing can involve short-term or longer-term measurements depending on the situation.

EPA guidance generally places testing in the lowest level of the home that could be used regularly, with appropriate testing conditions followed so the result is meaningful.

Professional testing may be useful when you need an independent measurement, are working through a real-estate transaction, need help following appropriate testing procedures, or want additional confidence in a result before making a mitigation decision.

Stage Two

Radon Mitigation

When mitigation is appropriate, the goal is to reduce the amount of radon entering and accumulating inside the home.

There is no single system configuration that is right for every property. The appropriate approach depends on the home's design and other site-specific factors.

Many common mitigation approaches use a combination of suction, vent piping, and a fan to move radon-containing soil gas away from the occupied space and discharge it outdoors.

Follow-up testing is an important part of determining whether the installed system is reducing radon as intended.

How It Works

Three Steps to Radon Mitigation Help

Understand the Result

Start with the information you already have.

Look at:

the measured radon level;
where the test was placed;
when it was performed;
how long it ran; and
the testing method used.

If the result or testing conditions are unclear, the next useful step may be additional testing or professional guidance rather than immediately choosing a mitigation system.

Evaluate Mitigation Options

A provider evaluating mitigation may consider factors such as:

foundation configuration;
accessible areas beneath the home;
potential suction strategy;
vent-pipe routing;
fan placement;
crawlspace conditions where applicable; and
how the home will be tested after installation.

The goal is not to select a system from a generic diagram. It is to understand why a proposed design makes sense for the particular home.

Connect With a Participating Provider

When you request help through YorkRadonHelp.com, HomePros Team reviews and manages the request.

HomePros Team may contact you for clarification and may connect or refer you to a participating independent provider when appropriate.

HomePros Team does not perform radon testing or mitigation.

Participating independent providers determine their own evaluations, recommendations, system designs, pricing, availability, contract terms, warranties, and contracted work.

System Anatomy

How an Active Soil Depressurization System Works

One of the most common approaches to reducing radon uses pressure differences to draw radon-containing soil gas from beneath the home and vent it outdoors before it can accumulate inside.

A typical active system may involve several recognizable components.

Fig. 01

01
Suction Point
A suction point provides a location where the system draws soil gas from beneath the home.
The number and placement of suction points depend on the property and proposed system design.
02
Vent Pipe
The vent pipe carries the collected soil gas away from the area beneath the home.
Its route depends on the property's layout and the system design.
03
Fan
An active system uses a fan to maintain the pressure needed to draw soil gas into the system.
04
Discharge Point
The system releases the collected soil gas outdoors through its designed discharge location.
05
System Indicator
A system indicator helps show whether the system is operating as designed.
It should not be confused with a radon test: system operation and measured indoor radon levels are different questions.

The exact design should be determined for the individual property rather than copied from a generic system diagram.

How does radon mitigation work?

Many homes can be addressed with systems that use suction, vent piping, and a fan to redirect radon-containing soil gas outdoors. EPA guidance emphasizes that the appropriate mitigation method depends on the home's design and other factors.

Cost

There Is No Single Fixed Price for Radon Mitigation

The cost of a radon mitigation system depends on the property and the work required.

Important cost factors can include:

PA DEP · January 2026 Guidance

$800–$1,200

Statewide typical range · Permanent system

PA DEP's January 2026 guidance states that permanent radon mitigation systems in Pennsylvania typically cost approximately $800–$1,200.

That is statewide guidance, not a York-specific quote, guaranteed price, or statement that every home will fall within that range.

A written proposal for a specific property is more useful than treating a statewide figure as a fixed local price.

How much does radon mitigation cost in Pennsylvania?

PA DEP's January 2026 guidance places a typical permanent mitigation system at approximately $800–$1,200 statewide.

The actual cost for a particular home can differ based on system design, foundation conditions, routing, electrical work, crawlspace requirements, and other project-specific factors.

Verify the Contractor

Verify the Contractor Before You Commit

Pennsylvania provides homeowners with an important verification tool: PA DEP operates a radon certification program and maintains an official directory for radon testing and mitigation services.

Pennsylvania generally requires certification for people or firms providing radon testing, mitigation, or laboratory services to others, subject to applicable exemptions.

Certification is an important verification step—but it should not be the only question you ask.

Before agreeing to work, consider checking:

whether the appropriate PA DEP certification is current;
who will perform any testing;
what work is included in the written scope;
why the proposed system design was selected;
whether post-mitigation testing is included or clearly addressed;
what warranty or service terms apply; and
how the written estimate compares with other proposals.

A contractor's certification does not eliminate the need to understand the proposed work.

Local Context

York and Pennsylvania Radon Context

Radon is not something you can reliably evaluate from the age, appearance, neighborhood, or location of a home alone.

York and York County include homes with basements, slabs, crawlspaces, and mixed foundations. Foundation configuration can affect how a mitigation system is designed, but the appropriate approach should be determined for the individual property—not from a map, a neighbor's result, or a regional average.

Pennsylvania DEP describes radon as a significant issue in the Commonwealth and estimates that approximately 40% of homes tested in Pennsylvania have radon levels above EPA's 4 pCi/L action guideline.

That is a Pennsylvania statewide statistic. It should not be interpreted to mean that 40% of York homes—or any particular York neighborhood or ZIP code—will test above 4 pCi/L.

PA DEP also maintains resources for:

radon testing;
mitigation;
professional certification;
provider verification;
monitoring; and
homeowner education.

These resources are useful for understanding Pennsylvania's broader radon context, but they do not replace testing an individual property.

Testing is the way to know the radon level in a particular home.

Post-Mitigation Testing

Should I Retest After Radon Mitigation?

Yes—post-mitigation testing is an important part of confirming the result after a system is installed.

A system that appears to be operating is not itself proof of the indoor radon concentration.

PA DEP homeowner guidance calls for follow-up testing after mitigation. Your provider should explain the post-installation testing process, including when testing will occur and who will perform it.

Ask about this before approving the scope so you understand whether testing is included or separately arranged.
