Radon Mitigation Norwood OH | Licensed RC202 Pros

If your Norwood home tested above 4.0 pCi/L, you have a defined problem with a defined solution. Radon Eliminator is Ohio's licensed radon mitigation contractor (Ohio Mitigation License RC202) installing EPA-aligned sub-slab depressurization systems across Hamilton County. We don't sell fans. We sell a documented number under the EPA action level, a clean install, and a system that will still be working in twenty years.

Norwood sits on the same Cincinnati Arch limestone and glacial till that drives elevated radon readings throughout southwest Ohio. The Ohio Department of Health classifies all of Hamilton County as Zone 1 — the highest radon potential. Homes built into the hillsides around Floral Park, Norwood Heights, and along Montgomery Road frequently test in the 4–10 pCi/L range, and basement-bedroom homes near Surrey Square and Linden Grove often run higher.

Radon Mitigation Norwood OH is what we do every day. Most jobs are installed in 4–6 hours. Post-mitigation testing confirms results in 48 hours. If you're under a real-estate contract, we work to your closing date — not ours.

Most local radon shops bury their license number, dodge real-estate deadlines, and won't quote a price over the phone. We do the opposite.

• Ohio Mitigation License RC202 — stated upfront, on every contract, on every system label. You can verify it with the Ohio Department of Health before we show up.
• Closing-Date Radon Service — productized for buyers, sellers, and Realtors. We schedule installation and post-mitigation testing around your contingency deadline, not our route convenience.
• Guaranteed below 4.0 pCi/L — in writing. If post-mitigation testing comes back high, we modify the system at no charge until it's compliant.
• Multi-vertical experience — single-family homes, condo associations, apartment complexes, commercial buildings, and Ohio schools. We're one of the few Ohio contractors who handle larger properties under ANSI/AARST CC-1000 and MAH-2019 protocols.
• Clear, published pricing — no "we'll have to come out and look." Most Norwood single-family installations fall between $1,295 and $1,850. We tell you that before we drive over.
• Home-inspector partner program — discounted testing rates and prioritized scheduling for inspectors who refer Norwood clients.

We offer the full scope of testing, installation, and verification services Norwood property owners need to resolve a radon issue once — correctly and on the record.

Active sub-slab depressurization (ASD) is the gold-standard solution for Norwood homes with basements, slabs, or crawlspaces. Our crews core a suction point through the slab, seal floor cracks and sump pits, run schedule-40 PVC vent piping to a designated discharge point above the eave line, and install a properly sized radon fan (RP145, RP265, or HP2200 depending on soil tightness). Every system includes a U-tube manometer, exterior labeling, and a system description placard per ANSI/AARST SGM-SF-2017.

Multifamily buildings, office buildings, and Ohio K–12 schools fall under ANSI/AARST CC-1000 (large buildings) and MAH-2019 (multifamily). These standards require diagnostic testing, communication testing under the slab, and properly engineered manifold systems — not a single fan strapped to a downspout. We're one of the few Norwood-area contractors licensed and equipped to design and install these systems for Norwood City Schools facilities, apartment complexes along Montgomery Road, and commercial properties in the Linden Pointe district.

EPA-aligned short-term testing (48-hour continuous radon monitors) and long-term testing for due-diligence cases. Real-estate testing is performed under closed-house conditions with tamper-resistant CRMs that log hourly readings — defensible if a buyer or attorney questions the result. Results delivered same-day after pickup.

Every installation includes a post-mitigation test 24–48 hours after activation to confirm the system has driven the level below 4.0 pCi/L. You receive a signed report with the pre- and post-mitigation values, system specifications, and the RC202 license number — exactly what title companies, lenders, and buyers' agents need at the closing table.

If you bought a Norwood home with an older mitigation system and the manometer reads zero, the fan is humming louder than it should, or the system is venting at grade instead of above the eave, we'll diagnose it. Common upgrades include fan replacement, sealing missed entry points, adding a second suction point in additions, and bringing exterior discharge into code compliance.

Predictable steps, predictable timeline. Here is exactly what happens when you hire Radon Eliminator for radon mitigation in Norwood.

1. Phone consultation & quote (same day). Share your test result, foundation type, and timeline. We provide a firm written quote — typically within an hour. No on-site sales visit required for standard installations.
2. Pre-installation diagnostic. On arrival, our RC202-licensed technician inspects the foundation, identifies the optimal suction point, and performs communication testing on tight-soil homes to confirm system design.
3. Installation (4–6 hours). Suction point cored, slab penetrations sealed, PVC vent stack routed (interior or exterior depending on home design), fan installed at code-compliant location, manometer mounted, electrical tied in by a licensed electrician where required.
4. Activation & post-mitigation testing. System energized, exterior discharge verified above the eave and 10 feet from any opening. A continuous radon monitor is placed 24–48 hours later to confirm the result.
5. Documentation delivered. Signed post-mitigation report, system warranty (5 years parts, lifetime workmanship), and RC202 documentation — emailed to you, your agent, and the title company on request.

Norwood is a fully landlocked city surrounded by Cincinnati, built largely between 1890 and 1955 on the limestone-and-shale geology of the Cincinnati Arch. That geology is the reason Hamilton County is an EPA Zone 1 radon area. Older homes throughout Norwood — the brick four-squares along Floral Avenue, the bungalows around Williams Avenue, the converted multifamily properties near Surrey Square Mall, and the newer infill construction off Smith Road — all share the same underlying radon source.

We've installed mitigation systems across every Norwood neighborhood: Norwood Heights, South Norwood, the Park Avenue corridor, the streets backing up to Xavier University, and the commercial buildings along the Norwood Lateral. We know how the older stone foundations behave (you need more sealing), how the 1960s slab-on-grade homes near Sherman Avenue respond (typically a single suction point handles it), and how the post-2000 construction in the Linden Pointe area is plumbed.

We also serve every surrounding community — Oakley, Pleasant Ridge, Hyde Park, Mariemont, Madisonville, Kennedy Heights, Amberley Village, and Silverton — usually with same-week scheduling. When real-estate timelines are tight in the Cincinnati metro, Norwood agents call us because we show up when we said we would.

Straight answers on cost, because nobody should have to call three companies to get a price.
