Radon Mitigation · Lincoln, Nebraska

High radon test result? Lincoln homes can be fixed.

Lincoln Radon Specialists helps homeowners in Lincoln, Waverly, Hickman, and the rest of Lancaster County with radon mitigation system installation, crawl space mitigation, radon testing, and system repair. Most homeowners reach out after a home radon test — often during a real estate transaction — comes back at or above 4.0 pCi/L. Call or fill out the quote form to talk through your reading and what a mitigation system for your home would involve.

You don't need to understand the fix before reaching out — a test result and your foundation type is plenty to start.

What your radon reading means

Results are measured in picocuries per liter (pCi/L).

04.0 — EPA action level8+

The EPA recommends fixing homes at or above 4.0 pCi/L and suggests considering it between 2.0 and 4.0. Roughly half of Nebraska homes tested come back at or above the action level — and a properly installed mitigation system typically brings levels well below it.

Radon services for Lincoln homes

Every home draws radon in a little differently, so the fix depends on what's under your floor. These are the four ways that gets handled.

Radon Mitigation System Installation

Sub-slab depressurization systems — the standard fix for most Lincoln basements and slab-on-grade homes. A suction point, pipe run, and fan sized and laid out to fit your foundation.

How installation works →

Crawl Space Radon Mitigation

Sub-membrane systems for homes with crawl spaces or mixed foundations, common in older Lincoln neighborhoods and on acreages outside town.

Crawl space details →

Radon Testing & Retesting

First-time tests, second opinions on a transaction result, and post-mitigation retests that confirm the system actually brought levels down.

Testing options →

System Repair & Fan Replacement

Fans that have stopped running, manometers reading zero, and systems installed by a previous owner that were never verified.

What happens after you call

Talk through your result

Share your test number, your foundation type, and whether there's a sump pit. That's all that's needed to start.

Get a quote

Some homes can be quoted from those details; others need a quick look at slab condition and routing options first.

System installed

Most standard installations are completed in a day: suction point, pipe run, fan, sealing, and a manometer so you can see it working.

Retest confirms it

A follow-up test verifies levels dropped below the action level — the number is the proof, not a promise.

Why Lincoln homes test high

Lancaster County sits in EPA Zone 1 — the highest radon-potential designation. The glacial soils under Lincoln release radon gas that gets pulled into homes through sump pits, floor cracks, and slab joints, and tight winter closed-house conditions concentrate it indoors. Older basements near downtown and in the Near South, newer walkouts in south Lincoln, and slab homes all draw it in differently — which is part of why mitigation systems aren't one-size-fits-all.

Newer Lincoln homes are often built with passive radon rough-in piping under Nebraska's radon-resistant new construction rules. Those systems frequently still test high until a fan is added — activating one is a smaller job than a full installation.

What affects the cost of radon mitigation

Most Lincoln mitigation systems fall in a fairly predictable range, but the specifics of your home decide where in that range you land: foundation type, whether a sump pit can serve as the suction point, how far the pipe has to run to a safe exhaust point, whether an attic or exterior route makes more sense, and how much sealing the slab needs. Homes with more than one foundation type sometimes need a second suction point. That's why quotes are discussed against your home's layout rather than promised instantly — a short conversation about your foundation usually narrows it quickly.

Common questions from Lincoln homeowners

My test came back just over 4.0 — do I really need to fix it?

The EPA recommends mitigating at or above 4.0 pCi/L, and considering it between 2.0 and 4.0. Radon levels also swing with seasons — a summer reading just over the line is often higher in winter, when the house is sealed up. If the result came from a real estate transaction test, the buyer's side usually expects mitigation. Call to talk through your specific number.

Can I get a quote if I only have the test number?

Yes. Your reading, your foundation type, and whether you have a sump pit are enough to start the conversation. Some homes can be quoted from that; others need a quick look first — either way, you don't need to figure anything else out beforehand.

Does Nebraska regulate radon work?

Yes — Nebraska licenses radon measurement and mitigation professionals through the Department of Health and Human Services, and mitigation systems are expected to follow recognized standards. It's one reason radon work in Lincoln shouldn't be treated as a DIY or general handyman job.

How long does installation take?

Most single-suction-point systems on a standard basement are installed in a day. Homes with combination foundations or long pipe runs can take longer — that gets covered when your quote is discussed.

My newer house has radon piping already. Why did it still test high?

Builders often install passive rough-in piping without a fan. Passive systems help, but in Zone 1 soil they frequently aren't enough on their own. Adding a fan to activate the existing piping is usually a smaller job than a full installation.

Is radon actually dangerous, or is this a real-estate formality?

Both, honestly. Radon is the second-leading cause of lung cancer in the United States according to the EPA, and it's also a standard checkpoint in Nebraska home sales. Whether you're fixing it for the sale or for the years you plan to live in the house, the fix is the same system.
