Ada sits in Hardin County, part of the Ohio radon belt the EPA maps as Zone 1 — the highest predicted indoor radon screening level in the country. That isn't marketing language; it's the Ohio Department of Health's own data. Roughly 1 in 3 Ohio homes tests above the EPA action level of 4.0 pCi/L, and homes built on the glacial till and limestone bedrock common around Ada, Kenton, Lima, and Findlay are especially prone to elevated readings.

If you just received a real-estate inspection report flagging high radon, or you're a property owner who pulled a do-it-yourself test and saw a number you didn't expect, you're in the right place. Radon Eliminator provides Radon Mitigation Radon Testing In Ada OH with a single goal: deliver a documented, defensible reading under 4.0 pCi/L on a permanent, code-compliant system — without blowing up your closing date.

We're licensed by the Ohio Department of Health under Mitigation License RC202. That number appears on every contract, every permit, and every post-mitigation test report we issue. Most competitors bury their license. We lead with it because that's the document that makes your result defensible to a buyer, a lender, a school board, or an insurance carrier.

When you search for the best Radon Mitigation Radon Testing In Ada, you'll find a short list of contractors and a long list of handymen. Here's what separates us — and why real-estate agents from Ada to Lima keep our number on file.

• Closing-Date Radon Service. We productize real-estate-deadline jobs. Tell us your closing date and we work backwards: pre-test, system design, install, post-mitigation test, and documentation — sequenced to hit the date.
• EPA-aligned testing protocols. Continuous radon monitors (CRMs) and AARST-NRPP measurement standards. No mail-in charcoal canister guesswork on transactional jobs.
• Multi-vertical depth. Single-family homes, apartment complexes, commercial buildings, and Ohio public and private schools. Most local shops can't handle a 24-unit apartment building or a K-8 school. We can.

We offer a complete scope of professional Radon Mitigation Radon Testing In Ada OH — designed around how Ohio properties actually fail, and how Ohio buyers, sellers, and inspectors actually buy.

Continuous radon monitor placed under EPA closed-house conditions for a minimum 48-hour test. You receive a tamper-evident, time-stamped report suitable for the purchase agreement. Most Ada-area tests are scheduled within 24–72 hours of your call.

The gold-standard mitigation method for the slab-on-grade and basement foundations common in Ada and surrounding Hardin County. We core the slab, install sealed PVC piping, run it to an exterior or attic-routed radon fan, and terminate above the roofline per AARST-CCAH standards. Properly designed, ASD systems routinely take a 12–20 pCi/L reading down to under 2.0 pCi/L.

Many older Ada-area farmhouses and ranch homes have dirt or partial crawlspaces. We install a sealed 12–20 mil vapor barrier with a depressurization mat and tie it into the mitigation system. This solves radon and moisture together.

Ohio law and ODH guidance hold commercial property owners, school districts, and apartment owners responsible for occupant exposure. We design multi-point mitigation systems for large slabs, conduct building-wide testing programs, and provide the documentation auditors and boards require. If you manage property near Ohio Northern University, an apartment complex on County Road, or a K–12 building in the Ada Exempted Village Schools area, this is the service line you need.

Every install includes a post-mitigation CRM test, a system labeling package, a homeowner operations sheet, and a transferable warranty. This is the paperwork that protects the sale — and protects the buyer for years after.

Here is exactly how our Radon Mitigation services Radon Testing In Ada OH run from first call to final report.

1. Phone consultation and written quote. Tell us the foundation type, square footage, and — if applicable — your closing date. We quote standard residential systems on the call.
2. Pre-mitigation diagnostics or initial test. If no recent test exists, we deploy a continuous radon monitor for 48 hours under closed-house conditions.
3. System design. Suction point location, pipe routing, fan sizing, and discharge point are designed to AARST-CCAH standards by an RC202-licensed technician — not subcontracted to a general handyman.
4. Installation. Most single-family systems install in 4–8 hours. We protect floors, vacuum the work area, and walk you through the system before we leave.
5. Post-mitigation test and documentation. A CRM is left on site for the required confirmation period. You receive the final report, system labels, and warranty within days — in time for closing.

Ada is a small Ohio village with big radon variability. Homes near the Ohio Northern University campus, along North Main Street, and out along State Route 235 sit on different soil profiles than homes closer to the Scioto Marsh or out toward Alger and Mount Victory. We've tested and mitigated across all of them.

We also work the wider Hardin County market — Kenton, Forest, Dunkirk, Dola, McGuffey — plus the I-75 corridor down through Lima and up toward Findlay. If you're searching for affordable Radon Mitigation Radon Testing In Ada or Radon Mitigation near me from a property in any of these communities, you're inside our standard service area.

One Ada-specific note: the older brick and block foundations on homes built between 1900 and 1960 around the village core often have multiple slab pours and rubble fill underneath. That changes suction-point strategy. A generic out-of-county installer who treats every basement the same is exactly how you end up with a system that hums along at 6.0 pCi/L and a buyer who walks. We design around what's actually under your slab.

Most single-family Radon Mitigation Radon Testing In Ada near me projects fall into a predictable range. Standard active sub-slab depressurization systems for a typical Ada home are quoted in writing on the initial call. Crawlspace encapsulation, multi-suction-point systems, and commercial scopes are quoted after a site visit. Testing-only services are flat-rate.

Typical timeline for a real-estate transaction:

• Day 0: You call. Written quote issued.
• Day 1–3: Pre-test deployed (if needed).
• Day 4–7: Mitigation system installed.
• Day 8–10: Post-mitigation CRM test.
• Day 11: Final documentation delivered to you, your agent, and the buyer's agent.

That's roughly a two-week round trip — built specifically for Ohio purchase-agreement timelines.
