Heard a neighbor mention radon and wondered if it’s a real concern in Sagle? You’re not alone. Radon is invisible and odorless, which makes it easy to ignore, but it is also a known health risk if levels are elevated. The good news is that testing is simple and affordable, and if you find a problem, proven fixes exist.
In this guide, you’ll get clear steps to test for radon in Sagle, understand results, and plan smart next moves whether you’re selling, buying, or settling into a new home. Let’s dive in.
Radon basics in Sagle
Radon is a naturally occurring radioactive gas that comes from the soil. It can enter your home through cracks and openings in the foundation and build up indoors. Long-term exposure increases lung cancer risk.
Northern Idaho, including Bonner County, is an area where elevated radon levels are possible due to local geology. Levels can vary from home to home, even on the same street, and they can change with seasons and weather. Testing is the only way to know your home’s radon level.
The EPA’s reference action level is 4.0 pCi/L. If the long-term average is at or above that, mitigation is recommended. Many homeowners also choose to reduce levels below 4.0 pCi/L because any reduction lowers risk.
Your testing options
You have three straightforward paths: a quick DIY screen, a longer baseline test, or a professional test designed for real estate.
Short-term DIY tests
Short-term kits, like charcoal canisters or electret detectors, run 2 to 7 days. Some extend up to 90 days. They’re great for quick screening before you list or while you’re planning an offer. Typical cost ranges about 10 to 40 dollars, including lab analysis. Follow placement instructions carefully and test in the lowest level you use regularly.
Long-term tests for accuracy
Long-term tests (usually alpha-track detectors) run 90 days to 1 year and give the best picture of your annual average exposure. Choose this route if your short-term result is near the action level, or if you want a clear baseline for health and disclosure. DIY long-term kits typically cost about 20 to 60 dollars.
Professional testing for transactions
Certified professionals often use continuous radon monitors that record hourly data. This is common during inspection periods because the results are detailed and widely accepted in negotiations. Professional testing costs more than DIY kits but can be the most defensible option when timelines are tight and documentation matters.
Where to find tests around Sagle
- Idaho’s state radon program: resources, certified tester and mitigator lists, and sometimes low-cost kits.
- Local hardware stores: short-term kits are often available through regional chains and local shops.
- Accredited labs: reputable vendors offer short- and long-term kits with prepaid analysis.
- Certified local radon professionals: use state or national directories to find North Idaho testers who provide CRM reports suitable for real estate.
When to test
Timing matters, especially in a real estate context. Here’s a simple plan.
Sellers: test before listing
Testing ahead of time lets you disclose results and handle mitigation on your schedule. Start with a short-term test. If results are above 4.0 pCi/L, get a mitigation estimate and decide whether to install a system before listing or be prepared to negotiate. If results are 2 to 4 pCi/L, follow up with a long-term test for a more accurate annual average.
Buyers: test during the inspection period
Arrange a professional short-term test with a continuous monitor during your inspection window. If levels come back above 4.0 pCi/L, you can request mitigation, negotiate a price credit, or allow the seller time to remediate before closing. Clarify in the purchase agreement who pays for testing and who handles mitigation if needed.
New homeowners: confirm your baseline
If no recent test is available, run a long-term test as soon as you can, especially during the first heating season. Winter closed-house conditions often reveal the highest levels in North Idaho. If your results are elevated, plan mitigation promptly.
Reading your results
- At or above 4.0 pCi/L: plan to mitigate.
- Between about 2.0 and 4.0 pCi/L: retest with a long-term detector to determine the annual average.
- Below 2.0 pCi/L: levels are lower, but there is no established safe level. Consider periodic retesting, especially after renovations or weatherization changes.
Because short-term results can be influenced by weather or ventilation, long-term testing is the best measure of year-round exposure.
Mitigation basics for Sagle homes
Most homes can be fixed using well‑proven methods.
How mitigation works
For homes with slabs or basements, the most common approach is active soil depressurization. A contractor installs a pipe and inline fan to draw radon from beneath the slab and vent it above the roofline. For crawlspaces, options include encapsulation with a sealed membrane plus ventilation or crawlspace depressurization. Sealing cracks helps but is not enough on its own.
Professional mitigators perform diagnostic tests to design the right system for your home. After installation, follow-up testing confirms the system works.
What to expect on cost and performance
- Typical professional systems often cost about 800 to 2,500 dollars depending on the home and scope.
- Reductions of 50 to 99 percent are common when systems are properly designed and installed.
- Fans run continuously and can last for years. Budget for occasional maintenance or fan replacement over time.
Choosing a qualified pro
Look for certified mitigators through state resources or national programs. Ask for references, proof of certification, a written estimate, the diagnostic plan, and details for post-mitigation testing.
Simple next steps for Sagle
Use this quick checklist to move forward with confidence.
Sellers: pre-list plan
- Run a short-term test under normal closed-house conditions.
- If results are above 4.0 pCi/L, get mitigation estimates and decide whether to install a system before listing or prepare to negotiate.
- If results are 2 to 4 pCi/L, follow up with a long-term test for your annual baseline.
Buyers: inspection strategy
- Schedule a professional test with a continuous monitor during your contingency window.
- If results are above 4.0 pCi/L, negotiate mitigation, a price credit, or remediation timeline.
- Confirm in your purchase agreement who is responsible for testing and mitigation.
New homeowners: set your baseline
- Run a long-term test within your first heating season.
- If elevated, hire a certified mitigator and verify performance with a post-mitigation test.
Where to get help
- Idaho Department of Health and Welfare radon program: guidance, certified pro lists, and potential low-cost kit options.
- Bonner County public health resources for local referrals.

What test should I use when buying a home?
- During the inspection window, a certified professional using a continuous radon monitor provides detailed, defensible results for negotiations.
Are short-term DIY kits reliable?
- Yes for screening, especially before listing or early in due diligence, but follow instructions closely and confirm near-threshold results with a long-term test.
When should sellers in Sagle test?
- Test before listing to avoid last-minute renegotiation. If results are 2 to 4 pCi/L, follow with a long-term test; if at or above 4.0 pCi/L, plan mitigation or negotiate accordingly.
How much does radon mitigation cost?
- Professional systems commonly fall in the 800 to 2,500 dollar range, depending on home size, foundation, and local labor, with post-install testing to confirm performance.
What if my short-term test is between 2.0 and 4.0 pCi/L?
- Run a long-term test for 90 days or more to determine your annual average and decide on next steps.
Do I need to retest after mitigation?
- Yes. Post-mitigation testing verifies the system is working and meets your target levels.
