Radon Testing Timed for Real Estate Deals

Radon Services for Home Buyers and Sellers

When you are buying or selling a home, radon testing often becomes part of the inspection process. Colorado has some of the highest radon levels in the country, and most lenders and buyers expect testing before closing. If elevated levels are found, mitigation may be required to move forward with the transaction.

Master Mitigators provides radon testing with fast turnaround results that fit real estate timelines. We schedule tests during the inspection period, deliver reports suitable for lenders and buyers, and offer mitigation when levels exceed recommended limits. Our systems are designed for basements, slabs, and crawl spaces, and we work quickly to avoid delays in closing.

If you need radon testing scheduled before your Denver closing date, contact Master Mitigators to arrange an appointment.

What Happens During a Real Estate Radon Test

We coordinate testing around your inspection schedule, placing devices in the lowest occupied level of the home. The test runs for at least 48 hours with windows and exterior doors kept closed as much as possible. Once complete, we retrieve the device and process results within one to two business days, giving you time to review findings before contract deadlines.

If radon levels come back at or above 4.0 pCi/L, mitigation is typically negotiated between buyer and seller. We provide mitigation quotes quickly and can install systems within days of approval. After installation, indoor radon levels usually drop below 2.0 pCi/L. Post-mitigation testing confirms the system is working and satisfies lender and buyer documentation requirements.

We include detailed reports with every test, formatted for real estate professionals and underwriting review. The mitigation systems we install are permanent, transferable with the property, and require minimal upkeep. Buyers gain assurance that radon has been addressed, and sellers avoid last-minute complications that could delay or cancel closing.

Common Questions About Radon in Real Estate

Buyers and sellers often have specific concerns about radon testing and how it affects their transaction. Here are the questions we hear most during real estate deals.

How quickly can radon testing be completed?
Testing takes a minimum of 48 hours onsite, and results are typically available within one to two business days after we retrieve the device. This fits most inspection timelines without issue.
What if radon levels are high during a sale?
If levels are at or above 4.0 pCi/L, mitigation is usually negotiated. We provide quotes quickly and can install a system within days, allowing the transaction to proceed on schedule.
Can the seller stay in the home during mitigation?
Yes. Installation takes four to six hours and does not require anyone to leave. We work in basements, crawl spaces, and exterior areas with minimal disruption.
Who pays for radon mitigation in a real estate deal?

Payment is negotiated between buyer and seller. It is common for sellers to cover mitigation costs or offer a credit at closing if elevated radon is discovered.

Why is radon testing so common?

Denver is located in a high-radon zone due to uranium-rich soil and bedrock. Lenders and buyers routinely request testing because of the elevated risk throughout the region.

Master Mitigators works with buyers and sellers to deliver radon testing and mitigation that supports smooth, on-time closings. If you need testing scheduled during your transaction, reach out to coordinate timing and reporting.
