Radon Mitigation Alexandria OH | Licensed RC202 Pros

Ohio has one of the highest average indoor radon levels in the United States, and Licking County sits squarely inside the EPA's Zone 1 — the highest-risk designation. If your Alexandria home tested above 4.0 pCi/L, you are not overreacting. You are reading the number the EPA, the Ohio Department of Health, and the U.S. Surgeon General all agree on.

Radon Eliminator is a licensed Ohio radon mitigation contractor (Ohio License RC202) serving Alexandria, Granville, Johnstown, Pataskala, and the wider Licking and Franklin County corridor. We design and install permanent, code-compliant sub-slab depressurization systems, then verify the result with a post-mitigation test. The deliverable is simple: a number under 4.0 pCi/L, in writing, signed by a licensed pro.

We are not a general contractor who also installs fans. Radon mitigation is what we do — for single-family homes off Northridge Road, century farmhouses on Refugee Road, new builds in the Granville school district, and commercial buildings along SR-37. Call (888) 527-7298 or request a quote and we will tell you the price, the timeline, and the guaranteed post-mitigation target before we hang up.

Most Alexandria homeowners calling us are in one of three situations: a real-estate inspection just flagged elevated radon and closing is in two weeks, a long-term test came back high and there are kids sleeping in the basement, or a commercial property manager just received a tenant complaint. Each one needs a different response — and a generic handyman cannot give it to you.

• Ohio License RC202 — we lead with it. Most competitors bury their license number or do not have one. Ohio law requires a licensed mitigation specialist for any installed system. Ask anyone you call for their RC number before you hire them.
• Closing-Date Radon Service — a productized track for real-estate transactions. We schedule around your closing date, not our calendar. Diagnostic visit, install, and post-mitigation test sequenced to fit a 10–14 day window when needed.
• Guaranteed result, not just a fan on the wall — every system is followed by a post-mitigation test. If the number is not below 4.0 pCi/L, we modify the system at no charge until it is.
• Multi-vertical experience — residential, commercial, schools, and apartment complexes. We understand ASD design for slab-on-grade ranches as well as sub-membrane systems for crawlspaces common in older Alexandria farmhouses.
• Clear pricing on the first call — most Alexandria systems fall between $1,200 and $2,200 installed, depending on foundation type, suction-point count, and exterior routing. We tell you before we show up.
• Home-inspector partner program — published referral pricing for licensed Ohio home inspectors who need a reliable mitigation partner for clients.

Radon mitigation is not one service — it is a sequence of services that has to be built around your foundation, your test result, and your timeline. Here is what we deliver in Alexandria.

The core service. We design an Active Soil Depressurization (ASD) system specific to your foundation — basement, slab-on-grade, crawlspace, or mixed. Suction points are core-drilled through the slab, sealed, and tied into a sealed PVC stack routed to a radon fan above the roofline. All installs follow ANSI/AARST RMS-SF standards and Ohio mitigation code. Includes manometer, labeling, electrical, and exterior aesthetics that respect the curb appeal of homes in neighborhoods like Williamsburg, Northridge, and the Granville Township corridor.

48-hour continuous radon monitor (CRM) testing using calibrated EPA-aligned devices, not charcoal canisters mailed to a lab. CRM tests give you hourly data, tamper detection, and a defensible report your buyer's agent will accept. Standard turnaround in Alexandria is 48 hours on-site plus same-day report delivery.

For apartment complexes, daycares, schools, and commercial buildings, we follow ANSI/AARST MAMF (multifamily) and CCAH (schools/large buildings) protocols. This includes building diagnostics, multi-zone testing per the AARST/EPA grid method, and engineered mitigation designs that account for HVAC interaction. Property managers in the SR-161 and I-70 corridors call us specifically because most local radon shops only handle single-family work.

EPA protocol requires a follow-up test 24 hours to 30 days after activation. We perform this in-house, document the result, and provide a sealed report for your records, your buyer, or your lender. If the number is not under 4.0 pCi/L, we adjust the system at no additional cost.

Many Alexandria homes have legacy mitigation systems installed 10–20 years ago with undersized fans, improper routing, or failed seals. We inspect, diagnose, and upgrade existing systems — often for a fraction of a full install — and re-test to confirm performance.

Every Alexandria project follows the same four-step process. No surprises, no upsells in the driveway.

1. Phone diagnostic & quote (same day). We ask about your foundation, your test result, and your deadline. You get a fixed-price quote on the call, not after a $200 site visit.
2. On-site assessment & system design. A licensed RC202 technician walks the basement or crawlspace, identifies the best suction-point location, and confirms exterior routing. Typically 30–45 minutes.
3. Installation (one day). Most Alexandria single-family installs are completed in 4–8 hours. Includes core drilling, PVC routing, fan mounting, electrical connection by a licensed electrician where required, manometer, and all sealing.
4. Post-mitigation test & documented report. 48-hour CRM test, signed report, and system warranty paperwork delivered to you, your agent, or your lender.

Alexandria sits on the western edge of Licking County in a band of glacial till and underlying limestone bedrock that is a known radon producer. The EPA classifies all of Licking County — including Alexandria, Granville, Johnstown, Pataskala, Newark, and Heath — as Zone 1, meaning predicted average indoor radon levels above 4.0 pCi/L. Ohio Department of Health data shows roughly 1 in 3 Ohio homes tested above the action level, and Licking County's rate trends higher than the state average.

Local construction patterns make it worse. Many homes around Alexandria and the Northridge Local Schools district are built on full basements with sump pits — a direct soil-gas pathway. Newer slab-on-grade builds in subdivisions off Johnstown-Alexandria Road have less basement volume but tighter envelopes, which concentrates radon that does enter. Older farmhouses on Refugee, Beech, and Dutch Lane Roads often have stone foundations or partial crawlspaces that require sub-membrane mitigation. We have installed systems in all of these configurations.

We also serve the broader region, including Granville (Denison University rentals), Johnstown, Pataskala, New Albany, Westerville, and into Columbus. If you are searching for Radon Mitigation near me or Radon Mitigation Alexandria near me, we are typically on-site within 2–5 business days, faster for real-estate deadlines.

Straight numbers, because no one else will give them to you:

• Standard basement system (single suction point, exterior fan): $1,200–$1,650
• Slab-on-grade or finished basement (interior routing, attic fan): $1,500–$2,000
• Crawlspace sub-membrane system: $1,800–$2,800
• Mixed foundation or multi-suction systems: Quoted on-site
• Pre-closing 48-hour CRM test: $145–$195
• Post-mitigation verification test: Included with installation

Financing is available for qualifying homeowners. Every system includes a workmanship warranty and a 5-year fan warranty. When people ask for the best Radon Mitigation Alexandria or affordable Radon Mitigation Alexandria option, the honest answer is the one installed by a licensed pro the first time — because a cheap system that does not get you under 4.0 pCi/L is the most expensive system you will ever buy.
