When Should You Test Your Home for Radon?

Before Buying or Selling a Home
Radon testing is a standard part of a thorough home inspection and often plays a role in Radon in Real Estate transactions.


After Renovations
Major home renovations can change air flow and foundation integrity, impacting radon levels.


Every 2–5 Years
Even if your home previously tested low, shifting soil or changes to air conditioning systems can alter readings.


If You Live in a High-Risk Area
Certain radon zones have naturally higher levels due to local geology.

FAQ: Residential Radon Testing
1. How long does a short-term radon test take?
A short-term radon test typically takes 2–7 days and provides an initial indication of your home’s radon levels.
2. What’s the difference between short-term and long-term tests?
Short-term kits offer quick results, while long-term radon tests measure levels over 90+ days, giving a more accurate year-round average.
3. Do I need to test for radon if my home has a mitigation system?
Yes. Even with a radon mitigation system, regular testing ensures it’s working effectively.
4. Can radon enter through my water supply?
In some areas, radon in water can contribute to indoor radon levels, especially if you use well water. Water testing kits can detect this risk.
5. Who regulates radon testing?
The Environmental Protection Agency and local Environmental Health Divisions provide guidelines for testing and mitigation, but homeowners are responsible for initiating tests.

What Our Clients Say?
David Hall2025-07-15Trustindex verifies that the original source of the review is Google. Very easy to work with, and very professional. John2025-06-27Trustindex verifies that the original source of the review is Google. Kent and the folks at ColoRadon are awesome!! I have an old house (1920) that posed a few mitigation challenges. The ColoRadon guys were able to expertly solve for those challenges, and successfully mitigate the radon in our home, sweet home! Barbara Harris2025-06-10Trustindex verifies that the original source of the review is Google. Kent and his employee Kevin are exceptional. They listened to our concerns and devised a plan that would work for us. Our radon measured 40.0 - 41.0 which was unbelievable to me but that was the results of our mail in test. After Kent installed the mitigation system our test came back at 2.9. I cannot even tell you how happy this made me. Thanks to Kent and his thinking outside the box he made a system that worked! Kent also installed a radon mitigation system in another one of my homes two years ago and it's working fabulously. I highly recommend ColoRadon. Barbara Harris Christopher S2025-05-19Trustindex verifies that the original source of the review is Google. We were in the middle of moving in our new house and Kent with Colorado Randon made everything so simple, it seemed like so many other things kept going sideways and anything that had to do with his tasks got done amazingly! Thanks for being on time with all of your services and even going out of the way to serve us in our Radon needs. I appreciate everyone I talked to and worked on our system, professional, and top quality services with great pricing! I absolutely will recommend Kent and this company to everyone. Natayle Brown2023-06-14Trustindex verifies that the original source of the review is Google. We’ve worked with Kent several times, always a pleasure! He’s tested for radon and installed radon mitigation systems for us a few times. We won’t go anywhere else - highly recommend! Emily Olinger2023-04-24Trustindex verifies that the original source of the review is Google. Kent is wonderful! He responded to my request for service super quick and was at our house the following day for a consultation. He was knowledgeable and professional. He answered all of our questions and provided us with a quote on the spot. He installed our mitigation system in a timely fashion and left our space cleaner than he found it. I highly recommend ColoRadon for your radon mitigation needs! Thank you Kent! :) LORI PUDLINER2023-01-22Trustindex verifies that the original source of the review is Google. Kent did an amazing job. He did a great job communicating when he was going to be late. He was professional, courteous and cleaned up after himself. He was very thorough in explaining the process and the test after the installation. Michele Razzari2022-11-29Trustindex verifies that the original source of the review is Google. We were referred to Kent thru our realtor when we moved to Colorado. Kent was awesome to deal with while we still lived out of state. He checked in when we arrived to complete a 2nd test after our radon mitigation installation. He was awesome to work with and easy to get ahold of! Dan Pahlau2022-08-19Trustindex verifies that the original source of the review is Google. Kent has worked on my home in other capacities in the past, but with ColoRadon, he removed a pigeon infestation and added netting around my solar panels on a roof that I was not equipped to deal with. He was responsive in scheduling, as always, did great work, cleaned up the huge mess it made and came in under budget. Can’t recommend him more if you need handyman work or radon work done! (He did radon mitigation, mold mitigation, and roof repair on my last home). Alison Goin2022-02-20Trustindex verifies that the original source of the review is Google. Great service, Kent is there when he says he will be, performs the work needed efficiently - cleans up after. Stays in contact thru the entire process. Highly recommended! He genuinely cares about resolving any radon issues.
