London, OH's Trusted Radon Mitigation Authority
Photo by AI Generated (Grok Imagine)If your London home tested above 4.0 pCi/L, you have a problem with a known, engineered solution — and you don't have to panic. Radon Eliminator delivers Radon Mitigation London OH property owners can rely on, backed by Ohio Mitigation License RC202 and an EPA-aligned testing and installation process used in homes, schools, and commercial buildings across Madison County.
Madison County sits inside Ohio's elevated radon zone. Soil and bedrock conditions across London — from neighborhoods near Choctaw Lake to older homes along South Main Street and newer builds off State Route 142 — push indoor radon concentrations above EPA action levels far more often than most homeowners realize. We've seen 6.8, 9.1, even 14+ pCi/L readings in homes that look completely ordinary from the curb.
The fix is permanent. A properly designed sub-slab depressurization system, installed to ANSI/AARST standards by a licensed Ohio mitigation pro, reliably drops indoor radon below 2.0 pCi/L and keeps it there. That's what we do — and we do it on a real-estate timeline when closings depend on it.
Call (800) 555-1234 for same-week scheduling in London and surrounding Madison County communities.
Why Choose Radon Eliminator for Radon Mitigation in London
London buyers, sellers, and agents call us because we remove the three things that usually go wrong with radon mitigation: unclear pricing, slow scheduling, and ugly, non-compliant installs.
- Ohio RC202 licensed. Every system is designed and installed under our active Ohio Department of Health mitigation license — not subcontracted, not handed off.
- Closing-deadline turnaround. When a London real-estate contract is on the line, we schedule testing and installation around your closing date, not our convenience. Same-week installs are standard.
- Transparent flat pricing. Most residential systems in London fall between $1,295 and $1,895 installed. You get the number before we show up — not after.
- Code-compliant, permanent systems. We build to ANSI/AARST SGM-SF-2017 standards with sealed sumps, manometers, exterior or interior routing options, and quiet inline fans — not a fan slapped on a pipe.
- Re-test included. Every install includes a post-mitigation radon test so the buyer, seller, and lender have documented proof the system works.
- Aesthetic placement. We route discharge pipes to minimize curb-side visibility. Front-facing PVC on a brick colonial is not our work.
If schools and apartment owners across Ohio trust us with their radon liability, your London basement is straightforward.
Our Radon Mitigation Services in London, OH

EPA-Aligned Radon Testing (48-Hour Results)
Continuous radon monitors deployed for the EPA-recommended 48-hour minimum with chain-of-custody documentation acceptable to lenders, real-estate brokerages, and Ohio disclosure requirements. Ideal for pre-listing screening or buyer due diligence in London.
Residential Sub-Slab Depressurization Systems
The gold-standard solution for London homes with basements, crawl spaces, or slab-on-grade construction. We core through the slab, seal entry points, install a dedicated radon fan rated for your home's footprint, and discharge above the roofline per code. Most installs complete in 4–6 hours.
Crawl Space Encapsulation & Membrane Systems
For older London homes with dirt or partial crawl spaces, we install reinforced vapor barriers, seal the perimeter, and tie the crawl into an active depressurization system. This is the only reliable fix for radon in pier-and-beam construction.
Commercial, Apartment & School Mitigation
Multi-unit and commercial buildings require engineered systems with multiple suction points, monitored fans, and documented compliance. We handle apartment complexes, dental offices, daycare facilities, and school buildings throughout central Ohio with ODH-compliant reporting.
Real-Estate Transaction Services
Test results in hand. Closing in 10 days. We design a workflow that fits: rapid quote, same-week install, post-mitigation re-test, and documentation forwarded directly to your title company or lender. Agents and inspectors get a single point of contact.
Our Radon Mitigation Process
Every London project follows the same disciplined four-step process. No surprises, no scope creep.
- Diagnostic Site Visit. We inspect your foundation type, sump configuration, slab condition, and HVAC layout. We identify the optimal suction point and discharge route — and confirm pricing before any work begins.
- System Design. Fan sizing is calculated against your home's square footage and substrate permeability. We don't oversize (loud, expensive) or undersize (fails re-test). We design to hit below 2.0 pCi/L.
- Installation. A licensed crew completes most London single-family installs in one day. Sealed sumps, manometer mounted, fan installed above the conditioned envelope, electrical to NEC standards.
- Post-Mitigation Re-Test. 24 hours after activation we deploy a continuous monitor for the EPA-required 48-hour post-test. You receive a written report showing pre- and post-mitigation pCi/L levels.
Local Expertise: Serving London and Madison County
London's housing stock is unusually diverse for a town its size — 1890s farmhouses near the courthouse on West High Street, mid-century ranches in the older grid neighborhoods, and newer developments stretching toward West Jefferson and Mount Sterling. Each construction era has its own radon entry profile, and we mitigate all of them.
We regularly work London ZIP code 43140 and surrounding communities including West Jefferson, Mount Sterling, South Solon, Plain City, and Lafayette. Our crews know the soil conditions around Deer Creek, the limestone bedrock that defines much of Madison County, and the specific permitting nuances of working inside London city limits versus unincorporated Madison County.
We also partner with London-area home inspectors and Madison County real-estate offices through our inspector referral program. If your inspector flagged radon above 4.0 pCi/L on a property near Choctaw Lake, off US-42, or anywhere in the London school district, we can usually quote within 24 hours and install within the week.
For context: the EPA recommends action at 4.0 pCi/L. Ohio's average indoor radon level is roughly 4 to 6 pCi/L — already above the action threshold. London-area readings frequently land in the 5–10 pCi/L range. A reading of 5.2 isn't a rounding error. It's a real exposure level that justifies a permanent mitigation system.
Pricing & What to Expect
Most London homeowners pay between $1,295 and $1,895 for a complete residential radon mitigation system, including post-mitigation re-test. Variables that affect price:
- Foundation type (basement, crawl, slab, or mixed)
- Suction point count (most homes need one; some need two)
- Interior vs. exterior pipe routing
- Crawl space membrane square footage, if applicable
Commercial and multi-unit pricing is quoted per building after a site walk. Financing is available for qualified buyers, and we work directly with title companies when mitigation is being credited at closing.
Compare that to the alternative: a deal that falls through, a buyer demanding a $5,000 credit, or a cheap fan-swap that fails re-test two weeks later. Affordable radon mitigation in London means doing it right the first time.
Frequently Asked Questions About Radon Mitigation in London
How much does radon mitigation cost in London?
Most single-family radon mitigation systems in London, OH cost between $1,295 and $1,895 installed, including the post-mitigation re-test. Pricing depends on foundation type, suction point count, and pipe routing. We quote a firm flat price before any work begins — no hourly billing, no surprise add-ons.
What is the best radon mitigation company in London?
Look for three things: an active Ohio mitigation license (ours is RC202), installation to ANSI/AARST standards, and a written post-mitigation re-test. Radon Eliminator meets all three and publishes our license number openly — many competitors don't.
How do I choose a radon mitigation provider in London?
Verify the Ohio license, ask for a flat written price, confirm the system will be code-compliant with a manometer and proper roofline discharge, and require a post-mitigation re-test as part of the quote. If a contractor won't put those in writing, keep calling.
What should I look for in radon mitigation services?
RC202 Ohio licensing, ANSI/AARST design standards, sealed sump covers, U-tube manometer for fan monitoring, exterior or aesthetic pipe routing, fan warranty (typically 5 years), system warranty, and EPA-aligned post-mitigation testing. All standard on our installs.
How long does radon mitigation take?
Most London residential installs take 4 to 6 hours of on-site work. From your call to a finished, re-tested system, the typical timeline is 5 to 10 business days. When a real-estate closing requires faster turnaround, we routinely complete the full cycle in under one week.
Is radon mitigation worth the investment?
Yes — and the math is straightforward. Radon is the second leading cause of lung cancer per the EPA and Surgeon General. A $1,500 mitigation system permanently removes that exposure. In a real-estate transaction, mitigation protects the deal and the appraised value. For commercial and rental property owners, it removes a documented liability.
