Colorado Springs Radon Pros

Radon Came Back High During Your Colorado Springs Closing

The inspection radon test on your Colorado Springs or El Paso County home came back at or above 4 pCi/L, and now there is a contract deadline attached to it. First, breathe: this is one of the most common and most solvable things that happens in a Colorado closing. El Paso County Public Health reports over 40 percent of county homes tested from 2005 to 2023 exceeded the EPA action level, so contractors, agents, and sellers here handle this every week. This page walks the buyer, seller, or agent through what happens next and connects you with an independent, Colorado-licensed radon professional who works on contract deadlines.

Four moves, in order

Read your contract deadlines first

Colorado sales run on the Commission-approved Contract to Buy and Sell, which sets an inspection objection deadline and an inspection resolution deadline. The exact dates are in your contract, so your agent is the first call, not a web article.

Negotiate who pays

A result at or above 4 pCi/L is a normal thing to raise inside the objection window. Buyers commonly ask the seller to pay for mitigation, credit it at closing, or fund an escrow holdback so the work finishes on schedule.

Schedule the fix inside the window

Most single-family mitigation systems install in one visit. Licensed contractors who work transactions can often fit the install, or an escrow arrangement for it, inside the resolution deadline so closing holds.

Document with a retest

A post-mitigation retest gives a written, lower number that travels with the deal file and satisfies the disclosure record Colorado now attaches to every residential sale.

The deadline is in your contract, not in a statute

Colorado residential sales use the Commission-approved Contract to Buy and Sell Real Estate. It sets an inspection objection deadline, the date by which a buyer must raise inspection issues like radon, and an inspection resolution deadline, the date by which the parties must agree on how to handle them. Those dates were negotiated into your specific contract, so the single most useful thing you can do the day a high result lands is ask your agent for both. The Colorado Division of Real Estate updated its Commission-approved forms to carry radon language after Senate Bill 23-206, detailed in its broker practice advisory. This page summarizes contract mechanics in plain language and is not legal advice.

How the fix fits inside the window

  1. 1

    Your request reaches a licensed contractor who works real estate deadlines and confirms scheduling the same business day where possible.

  2. 2

    A licensed measurement professional sets a continuous monitor for 48 hours under closed-house conditions and delivers a written, time-stamped report.

  3. 3

    If the result is at or above 4 pCi/L, a written mitigation quote follows fast, so the parties negotiate with a real number instead of a guess.

  4. 4

    The install is scheduled inside the resolution window, or an escrow holdback is arranged so closing proceeds and the work finishes right after.

  5. 5

    A post-mitigation retest documents the reduced level, and the paperwork travels with the deal file for the disclosure record.

Speed is not a reason to skip the license check

A deadline tempts everyone to hire the first available name. It takes under a minute to confirm that name holds the Colorado license the state has required for radon work since July 1, 2022, through DORA. Our license verification guide shows the two lookups, and the real estate radon page covers the wider transaction picture, including selling and military PCS moves.

Coverage and next steps

Deadline radon requests cover all of El Paso County and Teller County. For what a system involves, see radon mitigation; for the state-published price ranges, see the cost guide; and for the county numbers behind all of this, see radon levels in El Paso County.

Verify Your Contractor's Colorado Radon License

Since July 1, 2022, Colorado law has required anyone performing radon measurement or radon mitigation services for hire to hold a state license through the Department of Regulatory Agencies' Division of Professions and Occupations. The requirement was created by House Bill 21-1195. Before you sign anything, check the license and ask these three questions. A licensed contractor will welcome all of them.

  1. 1 May I see your current Colorado radon license number?
  2. 2 Is the person doing the work the licensed individual?
  3. 3 Will you retest after installation to confirm the reading dropped?

Radon During Closing Questions

My radon test came back high during closing. Will the deal fall through?

Usually not. Radon mitigation is a routine, well-understood fix, and an elevated result is common here: El Paso County Public Health reports over 40 percent of county homes tested from 2005 to 2023 exceeded the EPA action level of 4 pCi/L. The parties typically negotiate who pays, a licensed contractor installs a system before closing or through an escrow arrangement, and a retest documents the reduced level.

How long do I have to respond to a high radon result?

Your window is set by your specific contract, not by a fixed statewide number. Colorado sales use the Commission-approved Contract to Buy and Sell Real Estate, which carries an inspection objection deadline and an inspection resolution deadline. Ask your agent for those two dates the day your result comes in, because everything else keys off them.

Can I make the seller pay for mitigation?

Nothing is automatic, but radon is a standard item to raise inside the objection window. Sellers frequently agree to pay for the system, offer a closing credit, or fund an escrow holdback, because the alternative is putting the same disclosed result in front of the next buyer. Under Senate Bill 23-206, effective August 7, 2023, the seller already has to disclose known radon results, so a documented fix is often in everyone’s interest.

Can mitigation actually happen before closing?

Often yes. Transaction testing typically uses a continuous monitor over 48 hours, and most single-family systems install in a single visit. When the calendar is tight, the parties can agree to an escrow holdback so the closing proceeds and the install and retest finish just after. The contractor you are matched with confirms real dates in writing so your agent can align them with the contract deadlines.

Is a high radon result a health emergency I should move out over?

No. Radon is a long-term, cumulative risk, not an acute one: the EPA describes it as the leading cause of lung cancer among people who have never smoked, based on years of exposure. That is a reason to fix the home, not to panic during a closing. Handle it as a repair item on the timeline your contract already gives you.

What if I already closed and only tested afterward?

You still hold every option except the seller negotiation. Test to confirm the level, and if it is at or above 4 pCi/L, a licensed contractor installs a mitigation system and retests. It is a one-time fix on your own schedule now. Typical cost ranges published by the state are on our cost guide.
