What Is Radon Mitigation?
Radon is a naturally occurring radioactive gas that seeps up from the soil and enters homes through the foundation. Radon mitigation is the process of reducing that gas inside your home. The most common method is a sub-slab depressurization system: a pipe runs from beneath the basement slab to a fan, which pulls the gas out and vents it above the roofline.
The EPA recommends fixing a home when the radon level is 4 pCi/L or higher. In Pennsylvania, anyone who mitigates radon for hire must be certified by the Department of Environmental Protection (DEP) under the Radon Certification Act and 25 Pa. Code Chapter 240. That is why certification is the first thing worth checking.
How Did We Evaluate the Best Radon Mitigation Companies in York, PA?
We compared published service information, certification records, and available customer feedback in research completed on October 23, 2026. For installation providers, we checked the DEP mitigation register; Radon Mitigation York is listed using its own published services and certification, since it publishes this guide. Sources included:
- PA DEP Radon Services Directory (opens in a new tab) (October 1, 2026 list)
- Official company websites
- Verified profiles on third-party platforms
- Public customer reviews, read for patterns rather than averaged
- Published pricing, estimate policy, and warranty terms
In addition, we looked at several factors that matter for York homeowners:
- Current DEP mitigation certification and the personnel listed under each installation firm
- York or York County coverage, based on the company’s own statements
- Radon mitigation as a core service, not testing alone
- Evidence of installation or repair work
- Clarity about estimates, warranties, and follow-up testing
The comparison is based on public information. Certification establishes authorization for the relevant radon work, while customer feedback offers context about individual experiences. Confirm current credentials, address coverage, and the proposed scope directly with the contractor before booking.

1. Radon Mitigation York
Located In
805 E Prospect St, York, PA 17403
A Quick Overview
Radon Mitigation York is a PA DEP-certified radon mitigation firm (DEP #3241) working out of an office on East Prospect Street in the City of York. Radon is its only trade: its own crew runs continuous-monitor radon tests, installs sub-slab and sump-based mitigation systems, replaces failed fans, and repairs existing systems, including ones other companies installed.
Each job starts with a look at the foundation, followed by a written, home-specific design and price. After installation, the system is labeled, the manometer reading is recorded, and a post-mitigation test confirms the new level. The site also publishes York County radon data by town, local cost figures, and a guide to checking any contractor’s DEP certification.
Because the office sits inside the city, it focuses on ZIP codes 17401 through 17404 and the neighborhoods bordering them, which keeps scheduling short for homeowners working around an inspection deadline.
Its Manta listing (opens in a new tab) is marked as claimed and owner verified. Public profiles on ProvenExpert (opens in a new tab) and Houzz (opens in a new tab) provide additional places to check the published business name, York contact details, and website before making an inquiry.

Homeowners inside the City of York and its bordering neighborhoods who want a local, radon-only contractor, especially after an elevated result or when an existing system has stopped holding the level down.

How Much Does Radon Mitigation Cost in York, PA?
DEP records summarized by Radon Mitigation York on October 21, 2026 put the York County median system cost at $1,150 across 749 systems installed from 2024 to 2026. About half of jobs (50.9%) fell between $935 and $1,320. The median for a standard sub-slab system was $1,175, and activating an existing passive pipe was $775.
These are county statistics, not quotes from the companies above. System design, foundation construction, the number of suction points, existing equipment, and installation complexity all move the price.
Key Facts That Show Why Radon Mitigation Matters
Now that you know the options, here are a few facts that show why acting on a high result is worth it.
EPA recommends fixing homes at 4 pCi/L or higher. That is the level at which the EPA advises action. Lower levels still carry some risk, so you may want to consider mitigation between 2 and 4 pCi/L.
EPA estimates radon causes about 21,000 lung cancer deaths a year in the United States. Radon is the leading cause of lung cancer among nonsmokers, which is why testing and fixing a high result is considered a health priority.
The median York County system cost was $1,150 from 2024 to 2026. (PA DEP records, summarized by Radon Mitigation York) A quote from your own contractor is the only price that applies to your home.
97.5% of York County systems tested below 4.0 pCi/L afterward. (PA DEP records, summarized by Radon Mitigation York) That suggests properly installed systems usually work, but a post-installation test is the only way to confirm yours does.
What to Look for When Hiring a Radon Mitigation Company
There are several things you should not skip when selecting a contractor for your home. Here is a quick overview.
- Certification: Ask for the firm and individual DEP numbers, then confirm them in the current DEP Radon Services Directory.
- Written Estimate: It should name the system type, suction points, fan model, pipe route, and discharge point.
- Foundation Fit: Slab, sump pit, block wall, and crawl space each call for a different design.
- Fan and Pipe Placement: The fan belongs outside living space, with exhaust above the roofline.
- Post-Mitigation Testing: Get in writing who tests, when (after the system has run at least 24 hours), and what happens if the result is still high.
- Warranty: Look for duration, fan coverage, labor coverage, and who pays for repairs.
- Availability: Confirm the crew will travel to your address and when it can start.
- References and Insurance: Ask for recent local references and proof of liability insurance before work begins.

For homeowners inside the City of York, Radon Mitigation York is a strong starting point: a PA DEP-certified firm based in the city whose own crew handles testing, installation, fan replacement, and repairs, with a post-mitigation test to confirm the result.

FAQs
Who offers certified radon mitigation services in York, PA?
Radon Mitigation York and Absolute Radon Mitigation are both PA DEP-certified firms with York offices. Companies in Gettysburg, Camp Hill, Mechanicsburg, Harrisburg, and Willow Street may also serve York homes. An office location is not a service area, so confirm travel for your address.
Do radon mitigation companies in Pennsylvania need DEP certification?
Yes. Pennsylvania’s Radon Certification Act and 25 Pa. Code Chapter 240 require DEP certification for anyone who tests or mitigates radon for hire. DEP runs the certification program, renews credentials on a set schedule, and posts the current list in its Radon Services Directory.
How much do radon mitigation companies charge in York County?
DEP records show a York County median of $1,150 for systems installed from 2024 to 2026, with about half of jobs between $935 and $1,320. Individual estimates vary with foundation type, the number of suction points, and pipe routing, so get written quotes for your own home.
Should I compare multiple radon mitigation estimates?
Yes, but compare scopes, not only totals. Check whether each quote names the system design, includes follow-up testing, and states warranty terms. A lower price that omits the retest or limits repairs may cost more later, so ask each company to explain what its number covers.
How do I verify a radon mitigation contractor’s certification?
Ask for the company’s firm number and the installer’s individual number. Look both up in DEP’s monthly directory, where mitigation firm employees carry 7000-series IDs, and ask to see the installer’s current DEP ID card or certificate. Status can change between monthly updates.
Do radon mitigation companies offer post-installation testing?
Many do, but arrangements differ. Confirm in the written quote who performs the test, when it happens after the fan has been running, and what the company does if the result is still elevated. Radon Mitigation York runs a post-mitigation test on every system it installs and puts the result in writing.
