What Is Radon and Why Does It Matter?
Radon is a sneaky killer, born deep in the soil from the natural decay of uranium. It’s a gas—radioactive, odorless, tasteless, and invisible. That’s what makes it dangerous. You can’t see it filling the air inside your home. It seeps up through the ground, hitching a ride into your living space through cracks in your foundation, gaps around pipes, and even the tiniest pores in concrete. If your house has a basement, the odds are even higher that radon is finding an entry point.
Here’s the problem: radon doesn’t just show up and leave. It lingers, settling into the air you breathe daily. Over time—sometimes years of exposure—it can wreak havoc on your lungs. That’s because when you inhale radon, you’re also inhaling tiny radioactive particles. They embed themselves in your lung tissue, delivering consistent, low-dose radiation. This consistent exposure increases the risk of lung cancer. To put it bluntly, radon is the second leading cause of lung cancer in the U.S., right after smoking. And if you’re a smoker, your risk compounds exponentially.
For Atkinson homeowners, radon isn’t some abstract hazard—it’s present, it’s local, and it’s your responsibility to detect it. The gas doesn’t care about well-maintained floors or airtight windows. It’s coming in where it can, at levels that might be higher than the national average depending on where your house is built. That’s why testing and mitigation aren’t just good ideas; they’re essential steps in creating a safe home for your family. Don’t let radon hide in plain sight.
Radon in Atkinson, NH
Atkinson, NH, like much of New Hampshire, sits on granite-rich soil—a key player in elevated radon levels across the region. Granite contains trace amounts of uranium, which breaks down over time to release radon gas. This geological reality makes radon not just a hypothetical problem for homeowners in the area but a documented concern.
According to state data, radon levels in New Hampshire frequently exceed the EPA’s action level of 4.0 pCi/L (picocuries per liter), particularly in Rockingham County, where Atkinson is located. A 2016 survey found that roughly one-third of New Hampshire homes tested showed radon levels above this threshold. While radon can lurk at unsafe levels in any house regardless of age or design, certain factors in the Atkinson area—such as sandy soils that promote gas movement and older homes with unfinished basements—can make the problem worse.
Awareness is growing, but many Atkinson homeowners still remain in the dark about the radon risks hiding just beneath their foundations. Testing is the first line of defense, but if you live in Atkinson, there’s one hard truth: assuming your home is “safe” without testing is a gamble. And when it comes to radon, the stakes couldn’t be higher—your lungs depend on it.
Testing for Radon
Testing for radon in your home isn’t rocket science, but it does require some basic steps to get it right. First off, grab a radon test kit—it’s the easiest way to dip your toes into the process. There are two main types: short-term kits, which typically stay in your home for 2 to 7 days, and long-term kits, which measure radon levels over at least three months for a more accurate picture. Both are simple to use. You just follow the instructions, set it up in a frequently used room—think basement or living area—and let it sit. When the testing period ends, send the kit to the lab (most include prepaid shipping), and they’ll hit you back with the results.
If you’re the DIY type, short-term kits are a solid start, but they might not capture how radon levels fluctuate over time. Long-term tests? These are the gold standard for a clearer assessment. Still, if you’re leaning toward more precision or just want peace of mind, professional radon testing is the way to go. A certified specialist will handle the setup and analysis, giving you the most reliable data to act on.
The takeaway here: whether you go the DIY route or call in the pros, testing is step one. Don’t skip it. You need solid numbers before you can figure out your next move.
Effective Radon Mitigation Methods
When it comes to reducing radon levels in your home, the goal is straightforward: keep the gas from building up and ensure it’s safely vented outside. The most common and effective system for radon mitigation is sub-slab depressurization. This method involves installing a PVC pipe beneath the foundation slab to suck the radon out of the soil before it enters your home. A fan mounted either inside the pipe or outside the building helps to draw the gas up and away, releasing it harmlessly into the air above your roofline. It’s an elegant fix that works for most homes with basements, slabs-on-grade, or crawl spaces. Simple, effective, and proven.
For an added layer of protection—or in homes where serious air leaks are a factor—sealing foundation cracks can complement the main system. This doesn’t entirely stop radon from getting in, but it does reduce the pathways, making the depressurization system more efficient. Think of it as plugging leaks in a boat: less water means less bailing.
In some cases, improved ventilation systems in upper floors or crawl spaces can also assist in diluting indoor radon concentrations. This secondary approach might involve installing mechanical vents or air exchangers to encourage cleaner airflow through the home.
For those building new homes, consider passive radon-resistant techniques like placing a layer of gas-permeable material beneath the foundation, sealed under a plastic barrier. Passive systems lack a fan but can later be upgraded to active systems if necessary. Planning radon safety into the design stage is almost always cheaper than retrofitting later.
The takeaway? Mitigating radon boils down to a blend of redirecting, sealing, and ventilating. Whether your home needs a simple fix or a full-blown system, there’s a solution that fits.
Choosing a Qualified Radon Mitigation Professional
Finding the right professional to handle radon mitigation in your home isn’t a decision you should take lightly. Radon isn’t a DIY fix; it requires experience, proper training, and specialized equipment to address effectively. Start your search by looking for contractors who are specifically certified by recognized organizations like the National Radon Proficiency Program (NRPP) or the National Radon Safety Board (NRSB). These certifications ensure the contractor has undergone rigorous training and adheres to industry standards.
While certification is non-negotiable, it’s not the whole picture. Take the time to ask for references and check online reviews to gauge the reputation and reliability of the contractor. Prioritize candidates with a track record of success in your area—preferably someone who has worked on homes in Atkinson or the surrounding New Hampshire region. Local expertise matters when it comes to understanding unique geological factors that may influence radon mitigation.
Once you’ve shortlisted a few potential professionals, insist on written estimates that spell out the scope of their work. Beware of contractors offering one-size-fits-all solutions or suspiciously low bids. Effective radon mitigation often involves tailored strategies based on the design of your home, your initial radon levels, and other conditions, so a cookie-cutter approach won’t cut it.
Finally, don’t forget to ask about warranties and post-installation support to ensure the system is working as intended long-term. A reputable contractor won’t disappear after installation—they’ll remain a resource for follow-up testing, adjustments, or troubleshooting as needed. By doing your due diligence, you can secure a professional who not only reduces radon to safe levels but also provides the peace of mind you deserve.
Maintaining Your Radon Mitigation System
Installing a radon mitigation system isn’t a “set it and forget it” deal. To keep radon levels in your home consistently low, regular inspections and maintenance are non-negotiable. Radon fans, for example, have a lifespan of about 5 to 10 years. If your system’s fan burns out, the entire setup becomes about as effective as a broken umbrella in a storm. So, checking it periodically is crucial.
Start with a simple annual inspection: make sure the fan is running (you’ll usually hear a faint hum) and that the system’s visible parts—like vent pipes and seals—are intact. If you’re not into DIY checks, hire a trained professional to do it for you. While they’re at it, have them measure radon levels to ensure the system is still doing its job. Levels can fluctuate over time due to factors like earthquakes, erosion, or even new construction nearby that alters the soil.
Also, keep an eye out for any signs of wear and tear: condensation building up in pipes, new gaps in seals, or strange noises coming from the fan. Address these issues sooner rather than later, as small problems can snowball into expensive repairs. Think of maintaining your radon system like servicing your car: the more consistent you are, the lower your risk of ending up with a major problem.
Finally, if you’ve made upgrades to your home—such as finishing a basement or adding an addition—you’ll want to re-test your radon levels afterward. These changes can inadvertently open up new pathways for radon to enter, requiring tweaks to your mitigation setup. Consistent testing and proper maintenance aren’t just about keeping a machine running—they’re about ensuring peace of mind in your own home.
Taking Action for a Radon-Free Home
Radon isn’t just someone else’s problem—it could be in your home right now, silently putting your health at risk. The good news? You can do something about it. Start by testing. Grab a radon test kit or call a professional to get accurate results. If your levels come back elevated, don’t panic. Modern radon mitigation systems are designed to cut those numbers down fast and keep them low.
This isn’t one of those “let’s think about it next year” projects. Radon exposure is a long game, and every day counts. Whether you’re sealing cracks, installing a sub-slab depressurization system, or just committing to annual follow-ups, the key is moving forward. A radon-free home isn’t just safer—it’s peace of mind, delivered. Don’t leave it to chance. Take action. Today.

Atkinson radon mitigation — local context
Yes — Atkinson homes commonly need radon mitigation, because the granite bedrock that gives New Hampshire its nickname also releases radon. Atkinson sits in the southwestern corner of Rockingham County, drained west by tributaries of the Spicket River and east by tributaries of the Little River (per Atkinson town/USGS GNIS data), on Berwick Formation bedrock with nearby granite intrusions (USGS Mineral Resources). The EPA's Map of Radon Zones puts Rockingham County in Zone 2 (predicted average 2–4 pCi/L) — moderate, not the highest tier. Still, NH Dept. of Health & Human Services reports that of roughly 25,000 homes tested through its radon program, more than 30% exceeded the EPA action level of 4.0 pCi/L. For older Atkinson homes on granite, testing is the only way to know. Our radon mitigation service handles slabs and crawl spaces (sub-membrane depressurization for dirt/fieldstone). State radon cert RMS-113966. Radon mitigation runs $900–$6,000 (most jobs $1,950–$2,250); the $50 radon test is credited toward the job if you proceed.
What a recent customer said
"603 Basement Solutions was a great company to work with for radon mitigation for a home on a slab foundation. My first call was with Marisha who had patience to explain the process, like it wasn't their millionth time doing so… They did such a neat and tidy job, drilling the slab, installing the system very efficiently tucked behind a door, and filling a crack in the slab… Most importantly, our radon level dropped within 24 hours from 11.3 pCi/L to 0.48 pCi/L!" — Marjorie Mosquito (Google, 5★)
Frequently asked questions
What EPA radon zone is Atkinson, NH in?
Atkinson is in Rockingham County, which the EPA's Map of Radon Zones classifies as Zone 2 — a moderate zone with a predicted average indoor radon screening level between 2 and 4 pCi/L. That is below the highest tier (Zone 1, >4 pCi/L), which in New Hampshire applies only to Carroll County. A Zone 2 rating still means many Atkinson homes test at or above the EPA action level, so testing is the only reliable way to know your home's level.
Why do Atkinson homes have radon problems?
Radon in Atkinson comes from the uranium in New Hampshire's granite bedrock — Atkinson sits on the Berwick Formation with nearby granite intrusions, per USGS Mineral Resources. Statewide, NH Dept. of Health & Human Services reports that of roughly 25,000 homes tested through its radon program, more than 30% exceeded the EPA action level of 4.0 pCi/L. Older Atkinson homes with basements or fieldstone crawl spaces are especially worth testing.
How much does radon mitigation cost in Atkinson, and is the test free?
603 Basement Solutions charges $900–$6,000 for radon mitigation, with most jobs landing between $1,950 and $2,250. The radon test is $50 — not free — but that $50 is credited toward the job if you decide to proceed. We install sub-slab depressurization for slabs and basements, and sub-membrane depressurization for dirt or fieldstone crawl spaces. State radon cert RMS-113966.
