Radon Testing Near Me in De Graff, OH | Radon Eliminator

If you're searching for Radon Testing Near Me in De Graff, OH, you're almost certainly in one of three situations: an inspector's report came back hot mid-transaction, you read that Ohio has some of the highest radon levels in the country and want to know your number, or you own a commercial building, apartment complex, or school that has a legal duty to keep occupants safe. Radon Eliminator handles all three — under one Ohio Radon Mitigation License: RC202.

Logan County, including De Graff, sits inside EPA Radon Zone 1 — the highest-risk category, with predicted indoor screening levels above 4.0 pCi/L. That's not marketing fear; that's the U.S. EPA map. Homes along SR-235, near Indian Lake, and across the older housing stock north of CR-10 frequently test elevated because of the area's glacial till soils and limestone bedrock. We've seen it firsthand.

What sets us apart from the HVAC guy who "also does radon" or the national franchise reading from a script:

• Licensed Ohio radon specialists only — RC202, not a side gig.
• Closing-deadline scheduling — we won't blow up your deal. Tests placed within 24–48 hours, results returned promptly.
• Transparent flat pricing — published numbers, no "call for a quote" runaround.
• Multi-vertical experience — residential, commercial, schools, and multifamily apartment compliance work.
• Home inspector referral program with a defined Special Offer for De Graff-area inspectors.

Every property in De Graff needs a slightly different testing protocol depending on whether you're under contract, refinancing, leasing, or simply concerned. Here's exactly what we offer:

This is the test you need when you're under contract. We follow the EPA/AARST MAH (Multifamily and Single-Family Homes) protocol with continuous radon monitors (CRMs) — tamper-resistant, hour-by-hour readings, no mail-in charcoal kit guesswork. Devices are deployed in closed-house conditions in the lowest livable level, retrieved at 48 hours, and the signed report is delivered to buyer, seller, and agent in a format every Ohio title company accepts.

Not under contract? A 90-day alpha-track test gives a far more accurate annual-average pCi/L number, especially in De Graff where winter levels routinely spike 30–50% above summer readings due to closed windows and stack-effect pressure. Recommended for any family living in the home long-term.

Riverside Local Schools, daycare operators, and apartment owners in and around De Graff have specific legal exposure under ANSI/AARST MALB and MAMF protocols. We design device placement plans (one device per 2,000 sq ft of ground-contact floor area), provide chain-of-custody documentation, and deliver compliance-grade reports your insurer and attorney will actually accept.

If a mitigation system was just installed — by us or by someone else — Ohio code requires a follow-up test no sooner than 24 hours and no later than 30 days after activation. We do this work for other contractors and independent buyers who want an unbiased verification.

When your number comes back at or above 4.0 pCi/L, we design a permanent active soil depressurization (ASD) mitigation system built to ANSI/AARST SGM-SF standards. PVC sized to airflow, fan rated for Ohio winters, exterior discharge above the roof eave, and a U-tube manometer you can read in 5 seconds. Most De Graff homes are completed in a single day.

1. Schedule (same day or next day in De Graff). Call us with your closing date. We work backwards from it.
2. Device Placement. A licensed tech places a calibrated CRM in the lowest livable level, documents closed-house conditions, and instructs the occupant in writing.
3. 48-Hour Monitoring. The device logs hourly pCi/L, temperature, humidity, barometric pressure, and tilt/movement — making tampering obvious and results defensible.
4. Report & Recommendation. Within 24 hours of pickup, you receive a signed PDF report with the average pCi/L, hourly graph, and a clear recommendation. If mitigation is needed, we can have a crew on-site within days.

De Graff is a small village, but the housing stock is anything but uniform. Pre-1950 homes near S Main Street and the old B&O rail line frequently have stone or block foundations with open sump pits — classic radon entry points. Newer builds on the outskirts toward Quincy and Lewistown often have poured walls with passive radon stubs that were never connected. We've tested all of it.

We also routinely serve the surrounding Logan County communities: Bellefontaine, Quincy, West Liberty, Russells Point, Lakeview, and the Indian Lake corridor. If your agent is at the West Central Ohio Association of REALTORS® or your inspector is ASHI/InterNACHI certified, there's a good chance they already know our reports.

Local soil note: the glacial outwash and fractured limestone under much of western Logan County moves radon gas efficiently into basements. That's why De Graff homes often test in the 6–12 pCi/L range — well above the EPA's 4.0 action level but easily corrected with a properly designed system.

We're one of the few Ohio companies that publishes pricing because we believe the "call for a quote" game wastes everyone's time:

• Real Estate 48-Hour Test (single-family): typically $145–$195 depending on travel and home size.
• Long-Term Homeowner Test: starting around $95.
• Commercial / Multifamily / School Testing: custom-quoted by square footage and device count — typically the most affordable Radon Testing Near Me De Graff OH commercial option once you compare per-device pricing.
• Mitigation Systems: most De Graff single-family homes fall in the $1,195–$1,895 range with a transferable workmanship warranty.

Financing is available on mitigation work, and we honor a written estimate through your closing date.
