You failed a radon test in Colorado Springs
An elevated result in Colorado Springs, Monument, Fountain, Manitou Springs, or Woodland Park is an expected outcome given the region’s geology. Confirm it, get certified bidders, and treat it as the fixable building condition it is.
Pikes Peak region homeowners often already know the granite is a source, so the questions here are practical: whether a crawlspace needs a membrane, whether a mountain property with a walkout is different, and who is qualified given that Colorado issues no state radon license. The answer to the last one is NRPP or NRSB certification.
What an elevated result actually means
Confirm in the same location under closed-building conditions. Chinook events and wide daily swings make short-term readings noisier here, so a confirming measurement earns its keep. If a sale is running — and with this much relocation traffic many are — confirm and quote in parallel to protect the inspection window. Colorado compels nothing at any concentration, so what an elevated result creates is a negotiation, and a written quote from a certified contractor is what makes it concrete. The heating season produces the strongest stack effect and the most conservative closed-house readings. The Front Range’s wide daily swings and chinook wind events move house pressure noticeably, which makes short-term results here noisier than in steadier climates — a real argument for confirming borderline numbers before spending.
Your next four steps
Four steps, in this order. Confirm the result — a second short-term test or a longer-term measurement, run under closed-building conditions. Get written quotes from independent businesses holding a current NRPP or NRSB mitigation certification. Decide who pays, which in Colorado is a negotiation and not a legal mandate. Then verify with a post-mitigation test after the system runs. Nothing about a single elevated reading forces you out of your house or out of a contract. Ask for the post-mitigation measurement after twenty-four hours of runtime, in the original detector location, in writing, with the contractor’s current NRPP or NRSB certification identified on the same page. Where a crawlspace membrane was installed, confirm the verification measurement was taken in the living space above it rather than in the crawl itself.
If the result landed inside a deal
Colorado requires sellers of residential real property to give buyers a radon warning statement and the state’s radon brochure before a sale, and the standard seller’s property disclosure addresses radon testing and mitigation. Colorado does not require a seller to test or to mitigate — the response to an elevated result is negotiated like any other inspection finding.

Failed Radon Test questions in Colorado Springs & the Pikes Peak Region
We are on a tight military relocation timeline. What is the fastest responsible path?
Run the confirming test and the quoting simultaneously rather than in sequence, and ask bidders for a written design based on a site visit rather than a phone estimate. Make mitigation and a post-mitigation verification test a condition of closing so the outcome is documented even if the work finishes after you take possession. That sequence protects both the timeline and the result.
Does an elevated result put a sale in Colorado Springs at risk?
A high-turnover market shaped by military and defense employment, with frequent relocations and buyers arriving from every part of the country. Colorado does not license radon professionals at the state level, and no Colorado statute compels mitigation. Radon is negotiated as an ordinary inspection item, and buyers new to the region are often surprised how routine that conversation is here.
Am I legally required to mitigate in Colorado?
No. A result at or above 4 pCi/L is an EPA action recommendation, not an automatic legal obligation in a Colorado sale. What state law generally governs is disclosure — telling a buyer what you know — not whether a system gets installed. Who pays, and whether the work happens before closing, is negotiated between buyer and seller.
