What Is Radon?

Radon is a silent invader. You can’t see it, smell it, or taste it, but it’s there—creeping up from the ground. This naturally occurring radioactive gas is the byproduct of decaying uranium found in soil, rock, and water. Harmless outdoors where it disperses into the atmosphere, radon becomes a threat when it seeps into homes. It sneaks in through cracks in foundations, gaps around pipes, even the tiniest holes.

Once inside, it accumulates in the air you breathe. And there lies the danger. Radon exposure isn’t a passing concern; it’s a slow, invisible hazard. Stay in a home with high radon levels for years, and you might never notice any symptoms—until it’s too late. Prolonged exposure can damage lung tissue, significantly increasing your risk of lung cancer. In fact, radon is the second leading cause of lung cancer in the U.S., right behind smoking.

The takeaway? Radon is a small word with a big impact. It’s worth understanding because ignoring it doesn’t make it disappear.

Why Radon Is a Concern in Kittery, ME

Kittery’s radon problem isn’t a fluke. It’s baked into the land itself. Maine’s rocky geology, rich in uranium deposits, is like a slow-leaking radon factory sitting beneath your house. Combine that with the region’s cold climate, where homes are sealed tight for warmth, and you’ve got a perfect storm for elevated radon levels.

Then there’s the way houses here are built. Many homes in Kittery have basements—ideal spaces for radon to collect as the gas seeps up from the ground through cracks, sump pumps, and other paths of least resistance. What’s worse, local testing consistently finds radon levels over the EPA’s action limit of 4 pCi/L, meaning many Kittery homes already pose a tangible health risk. The risks from long-term radon exposure, especially lung cancer, grow each year homeowners delay taking action.

In short: radon isn’t just a generic issue here; it’s a hyperlocal one that demands attention, starting with proper testing and mitigation.

Testing for Radon

Testing for radon is where awareness turns into action. At its core, it’s about figuring out if this invisible, health-threatening gas is lingering in your living space—and to what degree. The process is straightforward but critical, as radon can’t be identified without the proper tools.

  • Methods: Start simple. Short-term radon test kits—available online or at local hardware stores—are an easy entry point. These kits generally involve leaving a small device in the lowest livable area of your home for 2 to 7 days. Long-term radon testing, on the other hand, spans 90 days or more and provides a more accurate picture of year-round radon levels, especially in a place like Kittery, where seasonal changes can affect radon concentration. Both options are relatively affordable and easy to use.
  • Timing: Timing matters. Conduct your tests during colder months, when windows and doors stay closed for extended periods. This minimizes ventilation and naturally reflects the highest possible radon levels your home might experience. It’s a pragmatic approach that ensures no surprises down the line.
  • Professional Testing: If a DIY test suggests radon levels above the EPA action threshold (4 pCi/L), consulting a certified radon professional is a smart next step. Pros bring advanced equipment, experience, and sometimes the peace of mind that a $20 home kit can’t offer. Bonus: professional assessments can help you understand why your home might be particularly vulnerable and what mitigation approach would work best.

In short, testing is the first and most non-negotiable move in dealing with radon. Whether you’re using a quick kit from the local store or bringing in the big guns with a certified radon tester, procrastination isn’t an option when health is at stake.

Radon Mitigation Options

Sub-Slab Depressurization Systems

Sometimes, the simplest solutions are the most effective. Sub-slab depressurization is the heavyweight champion of radon mitigation. It works by drilling a hole into the concrete slab (usually in the basement), installing a pipe, and connecting it to a fan that vents radon gas outside before it can enter your home. The science is simple: it lowers the air pressure beneath your home’s foundation, stopping radon from sneaking in. For houses with basements or slab-on-grade foundations, this method is the backbone of radon control—both reliable and affordable. At an average cost of $1,200 to $2,500, it’s an investment that pays off with peace of mind.

Crawlspace Mitigation

If your Kittery home has a crawlspace, handling radon may look a little different. Crawlspace mitigations often revolve around two tools: vapor barriers and ventilation. A polyethylene vapor barrier is laid over the soil in the crawlspace to physically block radon from drifting upward, and this is combined with a ventilation system that directs accumulated radon gas out of your home. Since crawlspaces are a bit of a wildcard in residential construction, these solutions vary by house—but when done right, they shut the door on radon infiltration.

Sealing Entry Points

Sealing cracks sounds like something you’d see on a DIY weekend to-do list, and while it’s not hard to do, it’s far from a stand-alone fix. Small gaps around pipes, floor joints, or foundation cracks have a way of inviting radon in. Filling these spaces with concrete caulk or epoxy reduces the pathways radon can take. When paired with a depressurization or ventilation system, this method acts like locking the screen door after shutting the main one—a useful backup that fortifies your home’s defenses. Cheap, fast, and easy—it’s a no-brainer addition to any mitigation strategy.

Importance of Professional Mitigation

Radon mitigation isn’t a DIY project. The systems that reduce radon levels effectively—whether it’s sub-slab depressurization or crawlspace venting—require precision and expertise to work as intended. Certified mitigation specialists don’t just install pipes and fans; they design tailored solutions based on the structure of your home, ensuring that radon gas is captured and vented properly.

When done wrong, a mitigation system can fail entirely—or worse, give you a false sense of security while radon silently builds up again. A professional brings the tools and knowledge to measure initial radon levels, install a system compliant with Maine regulations, and retest after installation to confirm the mitigation is working.

Also, keep in mind that radon mitigation often isn’t a one-size-fits-all situation. A Kittery basement riddled with old cracks or a home perched on granite-heavy terrain might require creative approaches. That’s where pros thrive—diagnosing the specifics and ensuring your system holds up long-term. It’s an investment in peace of mind, and more importantly, in the air your family is breathing every day.

Monitoring and Maintenance

Mitigation systems aren’t a ‘set it and forget it’ solution. Regular testing is essential to ensure that radon levels remain below the EPA’s actionable threshold of 4 pCi/L. Even the most well-designed system can lose effectiveness over time due to wear, environmental shifts, or unnoticed damage. Home radon levels should be tested every two years at a minimum, and more frequently if there are significant changes to the home, such as renovations or foundation work.

System components like fans, pipes, and seals demand occasional attention. Fans—the workhorses of most mitigation systems—typically last between five to ten years, depending on quality and usage. When a fan fails, it can silently render the system ineffective, so it’s wise to replace it promptly. Pipes should also be inspected for cracks or leaks that could allow radon to seep back into the home.

For peace of mind, many homeowners opt for annual system checkups by certified radon specialists. A professional can identify and fix issues you might overlook, keeping the system running at peak efficiency. Maintenance shouldn’t be seen as optional—it’s the backbone of long-term radon reduction and, ultimately, your family’s safety.

Local Regulations and Resources

Maine takes radon seriously, and so should you. The state has established clear guidelines to help residents navigate the risks and responsibilities tied to this dangerous gas. If you’re buying or selling a home in Kittery—or anywhere in Maine—disclosure of radon test results is not optional; it’s the law. Sellers must provide buyers with documented radon levels during the property transaction process. If the home has exceeded the EPA’s action threshold of 4 pCi/L, expect mitigation to take center stage in negotiations.

On the resource front, Maine’s Division of Environmental and Community Health offers valuable information on certified radon professionals for both testing and mitigation. The state also coordinates financial assistance programs that may help cover mitigation costs for qualifying households. Additionally, the Environmental Protection Agency (EPA) provides online guides that explain radon risks and mitigation strategies in clear, actionable terms.

Ignoring regulations and resources isn’t just reckless—it’s a potential legal and health liability. Proactive testing and mitigation aren’t just compliance measures; they’re a long-term safeguard for your household’s well-being.

Protecting Your Family's Health

Radon isn’t something you see, smell, or feel — but it could be a silent threat lurking in your home. Knowing the risks isn’t enough; action is what truly makes the difference. If testing reveals elevated radon levels, it’s not a question of “if” but “when” to address the problem. Radon mitigation isn’t just a home improvement project; it’s a life-saving measure.

Start with reliable testing — the kind that leaves no doubt. From there, work with certified professionals who understand the specific challenges homes in Kittery might face. Whether it’s installing a sub-slab depressurization system or sealing up entry points, the goal is the same: reducing radon levels to protect the air your family breathes every single day.

Think of this as an investment in longevity. Routine maintenance and follow-up testing ensure your mitigation system keeps doing its job, year in and year out. Your home is your sanctuary, and every step you take to make it safer reinforces that. Protecting your family’s health doesn’t have to be complicated. It just takes vigilance, action, and a commitment to safety.
