If a home inspector just handed you a radon result above 4.0 pCi/L, or a buyer's agent is asking for a radon test before your Dallas closing, you're in the right place. Radon Eliminator is Ohio's licensed radon mitigation company (Ohio Mitigation License RC202) installing permanent, code-compliant systems across Dallas, OH and the surrounding Harrison County area. We handle Radon Mitigation Dallas OH projects on real-estate timelines — testing in 48 hours, mitigation systems installed in a single day, and a post-mitigation re-test that documents your home is below the EPA action level.

Dallas sits in an Ohio region where elevated indoor radon is common. The EPA places much of Ohio in Zone 1 — the highest predicted radon zone — and homes here routinely test between 4.0 and 12.0 pCi/L. That's not a scare statistic; it's the baseline reality of building on Ohio's glacial till and limestone-rich bedrock. The good news: radon is a solvable problem with the right system and the right installer.

We work with four customer types every week: homeowners who tested high, buyers and sellers stuck mid-transaction, commercial and apartment owners legally responsible for safe air, and home inspectors who refer the work. Every project gets the same RC202-licensed installer, the same permanent system design, and the same transparent quote.

Most Dallas-area contractors won't tell you their license number. We lead with ours. Here's what separates Radon Eliminator from a generic handyman swapping fans:

• Ohio Mitigation License RC202 — verifiable, current, and required by Ohio law for any mitigation work. If a contractor can't give you a license number, walk away.
• Closing-deadline turnaround — short-term radon testing in 48 hours, mitigation system installation typically within 3–7 days of signed quote. We schedule around your closing, not our calendar.
• Permanent, code-compliant systems — sub-slab depressurization built to ANSI/AARST standards, sealed entry points, manometer, exterior discharge above the eave line, and a labeled electrical disconnect. No shortcut fan-swaps that fail a re-test.
• Multi-vertical proof — the same crew that mitigates Ohio schools, apartment complexes, and commercial buildings is the crew installing in your Dallas basement. If schools trust us with kids in classrooms, your home is straightforward.
• Transparent flat-rate pricing — most single-family Dallas homes fall between $1,295 and $1,895 installed. We quote in writing before any work begins. No surprise add-ons for sealing, electrical, or post-mitigation testing.
• Home inspector referral program — named pricing, dedicated scheduling line, and a Special Offer for the inspectors and agents who send work our way.

That's the difference between a permanent fix and a cheap repair you'll redo in two years.

We offer the full radon scope — testing, mitigation, and verification — for every property type in Dallas. No subcontractors, no handoffs.

Short-term continuous radon monitor placements for real-estate transactions, with EPA-aligned protocols and chain-of-custody documentation accepted by every Dallas-area lender, agent, and inspector. Hourly readings, tamper alerts, and a digital report delivered the day the monitor is retrieved.

The gold standard for Dallas homes with basements or slab foundations. We core through the slab, vent through PVC to a sealed exterior fan, and discharge above the roofline. Includes sealing of all visible slab penetrations and a U-tube manometer for ongoing performance verification.

Many older Dallas homes have partial crawlspaces. We install heavy-mil vapor barriers, sealed seams, and a sub-membrane depressurization fan that pulls radon-laden soil gas out before it enters the living space — often improving moisture and mold conditions as a bonus.

Ohio law requires schools and certain commercial properties to maintain safe radon levels. We design and install zoned mitigation systems for apartment buildings, retail centers, daycares, and schools across the Dallas region, including multi-point monitoring and reporting packages for property managers and compliance officers.

Every system we install is followed by a post-mitigation radon test, typically 24 hours after activation. You get a signed report showing the pre- and post-mitigation pCi/L levels — the document your buyer, lender, or inspector needs to clear the contingency and move to closing.

Here's exactly how a Dallas mitigation job runs from the call to the cleared contingency:

Call us with your test result, foundation type, and closing date. In most cases we can quote your mitigation system over the phone within 10 minutes. No house visit required for a standard residential quote — we've installed enough Dallas-area systems to know what your home needs.

On install day, our RC202 technician walks the basement, mechanical room, and exterior to choose the least visible pipe route. We take aesthetics seriously — most Dallas homeowners worry about an ugly white pipe on the front of the house. We route to side or rear elevations whenever the physics allow.

Core drill the slab, install schedule-40 PVC, seal slab penetrations, mount the radon fan outside (never in living space, per code), wire to a dedicated switched circuit, install the manometer, and label the system per ANSI/AARST standards. Typical install: 4–6 hours.

We deploy a continuous monitor for a minimum 24-hour post-mitigation test. Target: well below the EPA 4.0 pCi/L action level — most of our Dallas installs land between 0.4 and 1.5 pCi/L.

You receive the signed installation certificate, post-mitigation test report, system warranty, and operating instructions. This is the package your real-estate agent forwards to the buyer's side to close out the radon contingency.

Dallas, Ohio sits in Harrison County, in a part of eastern Ohio underlain by Pennsylvanian-age shales, sandstones, and coal seams. Uranium occurs naturally in these formations, and as it decays it produces radon gas that migrates upward through soil and into building foundations. It's not a question of whether your neighborhood has radon — it's a question of how much, and what's keeping it out of your living space.

We've installed and tested systems throughout Harrison County and the broader Tuscarawas, Carroll, and Jefferson County corridor. Older farmhouses around Dallas Township with stone foundations and dirt-floor crawlspaces almost always test high. Newer builds with poured concrete basements test better — but "better" still routinely means 5–8 pCi/L without mitigation. Homes on the ridgelines near Cadiz and along the Stillwater Creek drainage tend to test higher than homes in the valley bottoms.

This local knowledge matters when you're picking a contractor. A national chain quoting a Dallas job from a call center has no idea your soil is dense clay over fractured shale — which changes fan sizing and suction point design. We size systems based on what's actually under Ohio homes, not a generic chart.

We also know Ohio disclosure law. Sellers in Ohio must disclose known radon test results on the Residential Property Disclosure Form. A mitigated home with a current passing test is a clean disclosure. An unmitigated home with a known high result is a problem. We help sellers, buyers, and agents navigate that timeline cleanly.

Transparent pricing is how we win business. Here's what to expect for affordable Radon Mitigation Dallas projects:

• Standard residential mitigation (basement or slab): $1,295 – $1,895 installed, including post-mitigation test
• Crawlspace sub-membrane systems: $1,795 – $2,795 depending on square footage and accessibility
• Combination basement + crawlspace homes: $2,295 – $3,495
• Pre-listing or pre-purchase radon test: $145 – $195
• Commercial, school, and multi-family: custom quoted after site walk

Financing is available for qualified homeowners, and we offer dedicated pricing for real-estate transactions where the cost is being negotiated into the closing. Ask about our home inspector and Realtor referral program.
