Radon Mitigation Old Washington OH | Licensed RC202 Pros

Radon Eliminator is a licensed Ohio radon contractor (Ohio Mitigation License RC202) operating across Guernsey County and the greater Old Washington area. We lead with our license number because most companies you'll call in this region won't. If a contractor cannot quote you their Ohio license on the first phone call, they should not be installing a permanent suction system on your home.

Old Washington sits in a region of southeastern Ohio where glacial till, fractured shale, and limestone geology create elevated radon potential. The EPA classifies most of Guernsey County as Zone 1 — the highest predicted indoor radon screening level. That's not a marketing claim; it's the federal map. Homes here routinely test above the 4.0 pCi/L EPA action level, and basement-finished older homes along Old National Road and the surrounding hollows are especially prone to soil-gas intrusion.

What separates our Radon Mitigation Old Washington OH service from a general handyman or out-of-state franchise:

• Ohio RC202 licensed mitigation — every system designed and installed under state-recognized credentials.
• Closing-Date Radon Service — real-estate-deadline jobs are productized, not treated as a nuisance. We schedule around your closing, not ours.
• Multi-vertical experience — single-family homes, commercial buildings, apartment complexes, and Ohio K-12 schools.
• Documented results — every install ends with a post-mitigation test you can hand to a buyer, lender, or school board.
• Clear, upfront pricing — no "we'll need to come look first to give a number" runaround.

Our scope of work covers the full radon lifecycle — from the first short-term test through final system verification. Every service below is performed by an RC202-licensed technician following EPA mitigation standards (ANSI/AARST SGM-SF, RMS-MF, and RMS-LB protocols, depending on building type).

The most common installation in Old Washington homes is an active soil depressurization (ASD) system — a sealed suction pipe drawing from beneath the slab or crawlspace, routed through an inline radon fan, and vented above the roofline. We size the fan (RP145, RP265, or commercial-grade) based on slab area, sub-slab communication test results, and your home's specific construction. Sump-pit retrofits, crawlspace membrane systems, and dual-suction configurations for additions are routine work for us.

Typical residential installs in the Old Washington area run $1,295–$2,200, depending on configuration, accessibility, and whether you need a sub-membrane crawlspace system. We provide a flat quote in writing before any work begins.

Few Ohio radon contractors will touch a multifamily building or a school. We do this work routinely. Property managers and school administrators have a legal duty under Ohio Administrative Code 3701-69 to address radon in occupied spaces, and our crews are equipped for large-footprint depressurization, multi-fan manifold systems, HVAC-integrated solutions, and tenant-occupied installs that minimize disruption. If you own an apartment complex, nursing facility, or commercial building in or near Old Washington, you are the call competitors aren't taking.

If your inspection report came back at 4.2, 7.8, or 19 pCi/L and you're staring at a closing date two weeks out, this is exactly the situation we built around. We deploy continuous radon monitors (CRMs) for 48-hour EPA-protocol testing, install the mitigation system on the next available window, and run a post-mitigation test that documents levels below 4.0 pCi/L — all timed to land before your contingency expires. Agents, lenders, and title companies receive a clean, signed report.

If you already have a system installed by a previous owner or another contractor, we'll inspect the U-tube manometer, verify fan operation, evaluate venting compliance, and run a confirmation test. Many "installed" systems we audit in the Old Washington area are non-compliant — improper termination, no labeling, sub-spec PVC, or a fan that's been dead for months without anyone noticing.

Here is exactly what happens when you hire us for Radon Mitigation in Old Washington, OH. No surprises, no scope creep, no last-minute upcharges.

1. Phone diagnosis & flat quote (same day). We ask about test results, square footage, foundation type (full basement, crawlspace, slab-on-grade), and your timeline. You get a flat price in writing — usually within an hour.
2. On-site evaluation & sub-slab communication test. Our technician inspects the foundation, identifies the optimal suction point, and performs a pressure-field extension test to confirm fan sizing.
3. System installation (typically one workday). Core drilling, sealed suction pit, schedule-40 PVC routing, properly sized RadonAway fan, exterior or interior venting above the eave per ANSI/AARST standards, U-tube manometer, and required system labels.
4. Post-mitigation EPA-protocol test. 48-hour continuous monitor placement after a 24-hour system run-in. Results are emailed as a signed PDF.
5. Documentation packet. You receive the install diagram, fan specs, warranty, post-test report, and — if it's a real-estate transaction — a buyer/lender-ready summary letter.

From signed quote to documented results under 4.0 pCi/L is typically 5 to 10 business days in Old Washington.

Old Washington is a historic village along Old National Road (US-40) in Guernsey County, with housing stock that ranges from 19th-century brick homes near Main Street to mid-century ranches and newer builds along SR-285. Radon behavior varies dramatically by foundation age and construction:

• Older homes near the historic district often have stone or rubble foundations with significant soil-gas pathways — these typically require careful sealing in addition to active suction.
• Mid-century basement homes off Cadiz Road and Leatherwood Road frequently have block walls and unsealed sump pits — common entry points we address with sealed sump lids and sub-slab suction.
• Newer construction in subdivisions toward Cambridge and Lore City may already have passive radon stubs roughed in — we convert these to active systems for a fraction of a full retrofit cost.

We also serve surrounding communities including Cambridge, Byesville, Lore City, Salesville, Senecaville, Quaker City, and the broader I-77 / I-70 corridor. Our trucks are in Guernsey County weekly, so scheduling is fast.

Ohio ranks among the highest radon-exposure states in the country, and southeastern Ohio's karst and shale geology is a driving reason. The Ohio Department of Health reports that roughly 1 in 2 Ohio homes tested shows radon levels at or above the EPA action threshold. In Guernsey County, that ratio runs even higher in homes with finished basements — which is exactly where families put bedrooms and playrooms.

One of the most common complaints we hear is: "I called three companies and none of them would give me a straight price." We will. Here is what affordable Radon Mitigation Old Washington homeowners can expect:

• Short-term radon test (48-hr CRM): $145–$195
• Standard residential mitigation system (single suction point): $1,295–$1,650
• Dual-suction or crawlspace membrane system: $1,800–$2,400
