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.
