Why London, OH Property Owners Choose Radon Eliminator for Commercial Radon Services

Ohio sits inside EPA Radon Zone 1 — the highest-risk zone in the country — and Madison County is no exception. Soil-gas readings across London routinely come back above the EPA action level of 4.0 pCi/L, and commercial buildings with slab-on-grade foundations, crawl spaces, or basement-level offices are especially vulnerable. When a property owner, school board, or apartment manager needs Commercial Radon Services London OH done right the first time, they call a licensed specialist — not an HVAC company that dabbles in radon on the side.

Radon Eliminator holds Ohio Mitigation License RC202, the credential the Ohio Department of Health requires for any contractor installing radon mitigation systems on commercial, residential, school, or multi-family properties in the state. That license is not a marketing badge — it is a legal prerequisite. We publish it on every estimate, every permit, and every system label we install.

  • RC202-licensed mitigation for commercial, school, and multi-family buildings
  • EPA-aligned testing protocols using continuous radon monitors and ANSI/AARST-compliant placement
  • Closing-deadline turnaround — testing in 48 hours, mitigation systems installed in days, not weeks
  • Transparent, written pricing — no "call for quote" runaround
  • Lifetime-grade workmanship backed by a written system warranty and post-mitigation verification testing

If you are a London property owner, real estate agent, home inspector, or facility manager looking for the best Commercial Radon Services London has available, the credential to ask for is RC202. We have it. Most don't.

Our Commercial Radon Services in London, OH

Commercial buildings are not oversized houses. They have larger footprints, multiple HVAC zones, sealed slabs, sump pits, elevator shafts, and code requirements that residential radon contractors are not equipped to handle. Our professional Commercial Radon Services London OH team designs each system around the building — not around a template.

Commercial Radon Testing (EPA-Aligned, ANSI/AARST MAH-2019 Protocol)

We deploy calibrated continuous radon monitors (CRMs) across the lowest occupied levels of your building following the ANSI/AARST MAH-2019 multifamily and large-building protocol. For schools and commercial properties, we follow ANSI/AARST MALB and the EPA's Radon Measurement in Schools guidance. Reports are delivered electronically, signed by a licensed Ohio professional, and structured for lender, buyer, attorney, and Ohio Department of Health acceptance.

Active Soil Depressurization (ASD) Mitigation Systems

ASD is the gold-standard mitigation method recognized by the EPA. We install commercial-grade radon fans (RadonAway GP, HP, and XR series), Schedule 40 PVC riser piping, sealed suction pits, and U-tube manometers with system labeling that meets ANSI/AARST CC-1000 commercial code. Every system is sized to the building's footprint, sub-slab communication test results, and projected radon load — not guessed at.

Apartment & Multi-Family Radon Mitigation

Ohio landlords and HOA boards have a duty-of-care obligation to provide habitable, safe rental units. We design building-wide mitigation systems for apartment complexes throughout London and Madison County, including ground-floor and garden-level units where radon concentrates fastest. We coordinate around tenant schedules and document everything for your liability file.

School & Daycare Radon Programs

Ohio public and private schools, daycares, and Head Start facilities are increasingly being asked to demonstrate radon compliance. We provide full-building testing programs, mitigation design, and re-testing on the cadence the EPA recommends (every 2 years and after any major HVAC change). Reports are formatted for school board review and state reporting.

Real Estate Transaction Radon Services

This is where deals live or die. If an inspection report just flagged elevated radon on a commercial property, office building, or investment home in London and you have 10–14 days to close, call us first. Our real estate division is built around closing timelines: 48-hour test results, mitigation system installation typically within 5–7 business days, and post-mitigation clearance testing the buyer's lender will accept. We won't blow up your closing.

Our Commercial Radon Process — From Call to Clearance

Here is exactly how a commercial radon project moves through our shop. No mystery, no surprises.

Step 1 — Site Assessment & Quote (Same-Day or Next-Day). A licensed RC202 professional reviews your building plans or visits the property. You receive a written, itemized quote — line items for testing, system design, fan model, piping, electrical, sealing, and post-mitigation verification. No hidden fees.

Step 2 — EPA-Aligned Radon Testing. Continuous radon monitors are placed per ANSI/AARST protocol and run for a minimum of 48 hours under closed-building conditions. Results are emailed in a signed PDF report.

Step 3 — System Design & Permitting. If mitigation is needed, we engineer the system around the building's sub-slab conditions, run a communication test, and pull any required permits with the City of London or Madison County.

Step 4 — Installation. Our crews install the active soil depressurization system — riser piping, commercial fan, exterior discharge above eaves and 10 feet from openings, system label, manometer, and electrical tie-in to a dedicated circuit per code.

Step 5 — Post-Mitigation Verification. A second EPA-protocol test confirms levels are below 4.0 pCi/L (and we aim for under 2.0 pCi/L). You receive a clearance report suitable for lenders, buyers, attorneys, and the Ohio Department of Health.

Local Expertise: Serving London, OH and Madison County

London sits about 25 miles southwest of Columbus along US-42 and I-70, and the geology underneath it — limestone bedrock, glacial till, and the silty clay loams typical of the Darby Plains — is exactly the kind of soil that produces elevated indoor radon. We have tested and mitigated buildings throughout downtown London near Main Street and the Madison County Courthouse, in the industrial corridor along State Route 38, and in neighborhoods around London City Schools, Lake Choctaw, and the historic district near Glade Run.

We also serve the surrounding communities — West Jefferson, Mount Sterling, South Solon, Plain City, and Somerford Township — and coordinate with commercial property managers in Columbus, Hilliard, and Grove City when their portfolios extend into Madison County.

How much does commercial radon services cost in London?

Mitigation systems for small commercial buildings range from $2,800 to $5,500. Larger commercial, multi-family, and school projects are quoted at roughly $0.40 to $1.10 per square foot of slab after a free on-site assessment.

What is the best commercial radon services company in London?

The right benchmark is Ohio license RC202, EPA-aligned testing protocols, and verifiable commercial experience across schools, apartments, and office buildings. Radon Eliminator meets all three. Ask any company you are considering to put their Ohio mitigation license number on their proposal — many can't, because they don't have one.

How do I choose a commercial radon services provider in London?

Verify three things: (1) Ohio Department of Health mitigation license (the RC-series number), (2) experience with ANSI/AARST CC-1000 commercial code and MAH-2019 multifamily protocols, and (3) written, fixed pricing with a post-mitigation verification test included. If a contractor can't produce all three on demand, keep looking.

What should I look for in commercial radon services?

Look for active soil depressurization (ASD) system design — not passive systems or sealing-only work — sub-slab communication testing before fan sizing, commercial-grade fans rated for continuous duty, code-compliant exterior discharge, a U-tube manometer with system labeling, and a clearance test report you can hand to a lender, buyer, or state inspector.

How long does commercial radon services take?

Testing requires a 48-hour minimum exposure under closed-building conditions, with results delivered same-day after pickup. Mitigation system installation on a typical commercial building takes 1–3 days. Post-mitigation verification adds another 48 hours. For real estate transactions, we routinely move from initial call to clearance report in 7–10 days.

Is commercial radon services worth the investment?

Yes — and not just for health reasons. Long-term radon exposure is the second-leading cause of lung cancer in the U.S. according to the EPA. For commercial owners, the liability math is also clear: documented mitigation protects you from tenant claims, supports property valuation during sale, satisfies lender requirements, and in many Ohio counties is becoming a de facto standard of care for schools, daycares, and multi-family housing.
