Radon Mitigation Parma Heights OH | RC202 Licensed Pros

Ohio has one of the highest residential radon exposure rates in the United States, and Cuyahoga County — including Parma Heights, Parma, Seven Hills, and North Royalton — sits squarely in EPA Radon Zone 1. That means more than half of homes tested in this part of Northeast Ohio come back above the EPA action level of 4.0 pCi/L. If your inspection report came back high, you are not an outlier. You are typical for the zip code.

Radon Eliminator is a licensed Ohio radon mitigation contractor (Ohio Mitigation License RC202) serving Parma Heights with EPA-aligned testing and permanent, code-compliant sub-slab depressurization systems. We do not subcontract. We do not sell fans and walk away. We install a system, retest the home, and hand you a documented post-mitigation result under 4.0 pCi/L.

• Ohio License RC202 — stated upfront on every quote, every permit, every invoice.
• Closing-Date Radon Service — testing and mitigation timed to your purchase agreement, not our calendar.
• EPA-aligned protocols — ANSI/AARST standards for residential (SGM-SF) and multifamily/commercial (RMS-MF, RMS-LB) buildings.
• Multi-vertical experience — single-family homes, apartment complexes, schools, and commercial buildings in the Parma Heights area.
• Flat, written pricing — no day-of surprises, no "complications" upcharges after the crew arrives.

Our Parma Heights radon mitigation services cover every property type and every stage of the radon problem — from the first short-term test through final post-mitigation verification. Whether you are a homeowner on Pearl Road, a real-estate agent at a closing on Stumph Road, or a property manager responsible for an apartment building near Greenbrier Commons, we have the right protocol for your building.

The standard fix for elevated radon in a Parma Heights home is active sub-slab depressurization (ASD). We core through the basement slab, seal floor cracks and the sump (if present), run a sealed PVC vent stack to the roofline, and install a properly sized radon fan in an unconditioned space — attic or exterior — per ANSI/AARST SGM-SF. Most Parma Heights homes built between 1955 and 1985 (the ranches and split-levels common throughout the city) can be mitigated in a single day. Typical residential pricing runs $1,295 to $1,795 depending on slab construction, exterior aesthetics, and whether a passive stub already exists.

Multifamily buildings, schools, and commercial properties fall under different standards (ANSI/AARST RMS-MF for multifamily, RMS-LB for large buildings). These projects require sampling plans across multiple ground-contact units, engineered system design, and documentation that holds up to legal and insurance scrutiny. We handle apartment complexes, condominium associations, daycares, and commercial buildings across Parma Heights and the greater Cleveland area. If you own a building and a tenant or parent has asked about radon, call us before the lawyer does.

We perform short-term (48-hour) continuous radon monitor tests for real-estate transactions and long-term placements for homeowners who want a seasonal average. Continuous monitors log hourly readings, detect tampering, and produce a chain-of-custody report your buyer, lender, or attorney can rely on. Test results are typically delivered within 24 hours of pickup.

Every mitigation system we install is followed by a post-mitigation radon test — a non-negotiable step under EPA and ANSI/AARST protocols. Until that test reads below 4.0 pCi/L, the job is not finished. We document the reading, the system manometer reading, fan model, and warranty in a closeout package suitable for the buyer's file or the property's permanent records.

If your Parma Heights home already has a radon system but the manometer is flat, the fan is loud, or the post-mitigation test is still creeping above 4.0 pCi/L, we diagnose and upgrade. Common failures we see: undersized fans on multi-suction-point homes, unsealed sumps, fans installed in conditioned space (a code violation), and PVC discharges terminating below the eave instead of above the roofline.

Real-estate deadlines do not move. Our process is built around that reality.

We review your test report, the home's foundation type (slab, crawlspace, basement, or mixed — common in the older sections of Parma Heights off York Road), sump configuration, and HVAC. For commercial and multifamily, we build a sampling and design plan. You get a flat-rate written quote before any work begins.

We locate suction points to maximize sub-slab pressure field extension, choose a fan sized to your slab and soil permeability (RP145, RP265, or higher for porous gravel beds), and design the vent stack route to comply with ANSI/AARST discharge requirements — minimum 10 feet from operable windows, terminating above the eave.

A two-person licensed crew completes most Parma Heights residential installs in 4 to 6 hours. We core the slab, seal penetrations, install the fan, label the system per Ohio Department of Health requirements, and clean up. You can sleep in the house the same night.

We deploy a continuous radon monitor for a minimum 48-hour closed-house test, retrieve it, and issue a written report. If the reading is at or below 4.0 pCi/L — and on our installs it almost always lands well under 2.0 pCi/L — the system is verified. If not, we return at no additional cost to add a suction point or upsize the fan.

You receive the post-mitigation result, system schematic, manometer baseline, fan warranty (typically 5 years), and workmanship warranty. For real-estate transactions, this package goes straight to your agent or attorney for the closing file.

Parma Heights sits on the same glacial till and shale bedrock that drives elevated radon throughout Cuyahoga County. The post-war ranches and split-levels along Pearl Road, Olde York Road, North Church Drive, and the neighborhoods near Greenbrier Commons and Yorktown Lanes were built before radon was on anyone's radar — slab-on-grade or shallow basement construction with unsealed sumps and floor cracks that act as direct soil-gas pathways.

We have installed mitigation systems in homes near Greenbrier Park, in the apartment corridor along Pearl Road, in townhomes off Stumph Road, and in commercial properties near the Parma Heights / Parma border. We also serve neighboring Parma, Seven Hills, Brooklyn Heights, North Royalton, Strongsville, and Brook Park. Because we run the entire Cleveland metro from a local base, our trucks are usually within 20 minutes of any Parma Heights address.

One specific note for Parma Heights buyers: many homes here have finished basement bedrooms or rec rooms. That changes the risk calculation. EPA guidance treats a finished basement used as living space as a measurement zone — meaning the test belongs down there, not on the first floor, and the mitigation target applies to that occupied lowest level.

If you are a buyer, seller, agent, or attorney working a Parma Heights closing, here is what you need to know:

• Test turnaround: 48-hour test placement, results within 24 hours of pickup. Total: 3 days.
• Mitigation turnaround: Most installs scheduled within 5 business days of signed approval. Same-week installs are routine when the closing is tight.
• Post-mitigation retest: Add 3 days. Total radon resolution timeline from elevated result to documented clearance: under 14 days in most cases.
• Documentation: Closing-ready report with the RC202 license, fan warranty, and post-mitigation reading — what your title company and underwriter actually want.

We also run a home inspector partner program for Parma Heights and Northeast Ohio inspectors who refer radon testing and mitigation work. Ask us about referral pricing and co-branded reporting.
