Understanding Radon Risks in Newark & Licking County

Radon gas is a colorless, odorless radioactive gas produced by the natural breakdown of uranium in Central Ohio soil and rock. Because you cannot see, smell, or taste it, many Newark residents remain unaware of the dangers lurking in their basements.

Much of Licking County, including ZIP codes like 43055, 43056, and 43058, is mapped by the EPA as having elevated radon potential. Research indicates that nearly 75 percent of homes in this region exhibit high levels of radon—far exceeding the national average where roughly 1 in 15 homes tests high.

The health implications are serious. Exposure to radon is a leading cause of lung cancer, second only to smoking, and is responsible for an estimated 21,000 deaths per year. Long-term exposure to levels at or above 4.0 pCi/L significantly increases lung cancer risk, especially for smokers or former smokers. The combination of smoking and radon exposure can multiply cancer risk by a factor of ten.

Radon can seep into Newark homes through multiple pathways:

  • Cracks in basement floors and foundation walls
  • Gaps around plumbing penetrations and drains
  • Crawl spaces with exposed soil
  • Sump pits and floor drains
  • Porous block walls and openings in the foundation

Many of the historic buildings in Newark, Ohio, are particularly susceptible to radon entry due to their age and construction methods, making radon mitigation especially important for preserving both health and heritage.

Common Radon Levels and Standards in Central Ohio

The EPA action level of 4.0 pCi/L represents the threshold at which mitigation is strongly recommended—though it’s important to understand that no truly safe level of radon exists, as risk increases linearly with concentration. The primary goal of radon mitigation in Newark, Ohio is to lower radon levels below the EPA action level of 4.0 pCi/L, ensuring a safer indoor environment for your family.

Key thresholds for Newark homeowners:

Radon Level (pCi/L) Recommendation
Under 2.0 Generally considered low risk
2.0 – 3.9 Consider mitigation, especially with risk factors
4.0 and above Mitigation strongly recommended by EPA

Many Newark homes tested by local agencies and home inspectors routinely measure above 4.0 pCi/L without a radon mitigation system in place. Dor-Mar recommends repeat or continuous monitoring after any major basement renovation or foundation work, as construction can alter how radon enters your home.

Radon Testing for Newark, Ohio Homes

Testing is the only way to determine your home’s radon level. The EPA recommends testing for all Newark residences, including new builds—modern, energy-efficient construction can actually trap more radon indoors due to tighter building envelopes. Homeowners are encouraged to learn more about the health risks of radon exposure and the importance of regular radon testing to protect their families.

Types of tests we offer:

  • Short-term tests (2–7 days): Provide quick assessments using charcoal canisters or alpha-track detectors, ideal for real estate transactions or initial screening
  • Long-term tests (90+ days): Deliver a more precise yearly average, accounting for seasonal fluctuations—radon measurement often peaks in winter when homes are sealed tighter

We place EPA-approved test devices in the lowest livable level (often Newark basements or first floors) and follow strict handling protocols in accordance with state of Ohio regulations and guidelines to ensure accurate results. Dor-Mar provides clear, written results in pCi/L with simple interpretation and next-step recommendations.

Key situations when you should test:

  • Buying or selling a Newark home
  • Finishing a basement or adding living space below grade
  • After mitigation installation to verify system effectiveness
  • Every 2–3 years as a routine health checkup
  • Following major foundation repairs or renovation

Professional vs. DIY Radon Testing

Newark residents can choose between low-cost DIY kits and professional radon testing, and each approach has its place.

DIY test kits from hardware stores can serve as useful screening tools. However, they require careful placement according to instructions, proper timing, and mailing to a certified lab—errors in any step can compromise results.

Benefits of Dor-Mar’s professional testing:

  • Correct device placement by trained technicians
  • Chain-of-custody documentation for real estate and legal purposes
  • Calibrated, professional-grade equipment
  • Quicker, more reliable lab reporting
  • Expert interpretation of results

Our team can integrate radon testing with other home comfort services during the same visit. If you’re scheduling an HVAC tune-up or indoor air quality inspection, we can add radon testing efficiently—saving you time and ensuring comprehensive protection for your Newark home.

How Radon Mitigation Works in Newark Homes

Most Newark homes use active sub-slab depressurization systems to safely vent radon outside before it accumulates in living spaces. This is the most effective method available, capable of achieving reductions up to 99 percent when properly designed. It is important that a licensed radon mitigation contractor installs the system to ensure safety and effectiveness.

The process in simple terms:

  1. We create a suction point by drilling through the basement slab or installing a collection point in the crawl space
  2. PVC piping connects this suction point to a specialized radon fan
  3. The fan draws radon-laden air from beneath your foundation
  4. Radon is vented safely above the roofline where it disperses harmlessly
  5. The contractor should also seal all cracks and openings in the foundation floor and walls as part of the mitigation process

Systems run continuously, using modest electricity—typically 90–120 watts, similar to a bathroom fan. Monthly operating costs stay under $5 in most cases. When installed correctly, these systems are quiet and unobtrusive.

Sealing cracks and penetrations supports the system’s effectiveness, but sealing alone is not sufficient to solve high radon levels. Research shows that sealing without active depressurization typically reduces radon by only 10–50 percent and fails over time as new cracks form.

Mitigation Approaches for Common Newark Home Types

Newark features a mix of older 19th and 20th century homes alongside newer subdivisions, and each requires a tailored design approach.

Full basements: Sub-slab depressurization with one or more suction points works effectively for most basements. Piping can be routed through the basement, rim joist, or outside wall depending on layout and homeowner preferences. Multiple suction points may be needed for larger footprints or complex foundation configurations. For example, in a Newark home with a finished basement, installing a sub-slab depressurization system reduced radon levels from 8.5 pCi/L to below 2.0 pCi/L within days, demonstrating the effectiveness of proper mitigation.

Slab-on-grade homes: We install an external suction point near the slab perimeter, with exterior piping and fan placement that maintains curb appeal. Careful routing along corners and behind landscaping keeps the system discreet.

Crawl spaces: The approach involves sealing exposed soil with heavy-duty plastic sheeting (vapor barrier) and installing a sub-membrane depressurization system. This method addresses both radon and vapor intrusion concerns while improving overall crawl space conditions.

Dor-Mar evaluates structural features, existing sump pumps, finished basement areas, and aesthetic considerations to choose the most effective and discreet layout for your property.

Step 4: System Startup We verify proper vacuum under the slab using a manometer, label all system components, and explain operation and what to monitor. You’ll know how to confirm your system is working correctly.

Step 5: Post-Mitigation Test We arrange a follow-up radon test (usually after 24–72 hours of continuous system operation) to confirm levels have dropped below the EPA guideline. This verification test documents the system’s effectiveness for your records and any future real estate transactions.

Appearance, Noise, and Maintenance Considerations

Many homeowners worry about how a radon system will look on their property. Rest assured that systems can be installed neatly and discreetly on Newark homes.

What to expect:

  • Fan locations: Typically mounted on an exterior wall, in the attic, or in an attached garage
  • Piping aesthetics: PVC color and routing can be chosen to blend with siding, trim, or foundation materials
  • Noise levels: Radon fans produce a low hum similar to a bathroom exhaust fan—barely noticeable during normal activities
  • Maintenance: Minimal requirements; visually check the system’s warning indicator or manometer periodically. Homeowners should also watch their system’s indicators and radon levels regularly to ensure continued safety.

Call Dor-Mar if readings change significantly or if you notice unusual fan noise. Periodic checkups help ensure long-term system performance.

Frequently Asked Questions about Radon Mitigation in Newark, Ohio

How common are high radon levels in Newark and Licking County?

Many homes in Licking County, including Newark, test at or above the EPA action level of 4.0 pCi/L due to local geology and soil composition. Research suggests approximately 75 percent of homes in this region have elevated levels—significantly higher than the national average.

Even houses next door to each other can have very different radon levels because of variations in foundation construction, soil conditions, and home ventilation. That’s why every Newark home needs individual testing regardless of what neighbors have found.

Newer construction isn’t automatically safer. In fact, tight, energy-efficient homes can sometimes trap more radon indoors due to reduced air exchange with the outdoors.

Will a radon system hurt my home’s appearance or resale value?

Professionally installed systems are designed to be as discreet as possible. Technicians route piping along corners, behind downspouts, or through less visible areas when feasible. Pipe colors can be matched to siding or trim.

Having a documented, effective radon mitigation system is often seen as a selling point in Central Ohio real estate transactions. Buyers appreciate knowing the home has been tested and protected.

We recommend keeping all test results, system diagrams, and warranty paperwork. This documentation demonstrates due diligence to future buyers and satisfies home inspections requirements during sales.

How long does a radon mitigation system last?

PVC piping can last for decades with no maintenance required. Radon fans typically have a service life of 10–15 years under continuous operation, though some last longer depending on the model and conditions.

Newark homeowners should listen for changes in fan noise and check system indicators periodically. If the fan fails or readings increase, call Dor-Mar for service. Fan replacement doesn’t require redoing the entire system—we can swap the fan while keeping existing piping intact.

Can I run my radon fan only part-time to save electricity?

Radon fans are designed for 24/7 continuous operation and draw relatively low power—typically under $5 monthly. Running a fan intermittently defeats the system’s purpose.

Shutting the fan off allows radon levels to rise quickly back above the EPA guideline, especially in Newark’s higher-radon soils. Within hours of turning off a system, indoor levels can return to pre-mitigation concentrations.

Continuous operation with occasional retesting (every 2–3 years) confirms that your system maintains low levels over time. If you’re considering improving your home’s heating system, learn more about whether you should replace your standard furnace with a new high-efficiency unit.

Does my homeowners insurance or warranty cover radon mitigation?

Most standard homeowners policies do not automatically cover radon mitigation as a claim—radon is typically considered a pre-existing environmental condition rather than sudden damage. However, coverage varies by insurer, so it’s worth checking your policy.

Some home warranty programs may offer discounts or partial coverage for indoor air quality improvements. Ask your insurance agent and warranty provider about available benefits.

Dor-Mar provides detailed estimates and documentation that can support financing applications, negotiation during home sales, or reimbursement claims where coverage exists.
