Comprehensive Radon Services for New Construction
Building a new home is an opportunity to create a healthy and safe environment from the ground up. In areas with high radon potential, such as Colorado, it's crucial to consider Radon Gas a primary concern.




Radon Mitigation for New Construction
Our primary focus is on Radon Resistant New Construction (RRNC). We work with builders to incorporate radon-resistant features during the construction phase, which is a far more effective and affordable approach than retrofitting a finished home.
Our new construction mitigation services are built on a solid understanding of radon mitigation standards and safety standards, including those from the National Radon Proficiency Program. This process involves

Sub-Slab Depressurization
A soil gas collection plenum is installed beneath slabs and crawl space environments to create an easy path for soil gases to be collected.

Vapor Retarder
A layer of heavy duty vapor barrier is laid over the substrate and sealed to the foundation walls using polyurethane sealant when required.

Passive Radon System
A solid PVC vent pipe is installed, running from the collection layer up through the interior of the home and out above the roofline.

Sealing
All cracks, joints, and utility openings in the foundation are sealed with durable caulking to prevent radon entry.

Junction Box
In coordination with the contractor, an electrical junction box is pre-wired near the vent pipe, preparing the system for easy fan installation if needed.
By integrating these features from the start, we build a foundation of health and safety that will last the lifetime of the home, aligning with modern building codes and radon mitigation techniques.
Our New Construction Services

Radon Testing
Ensure your project meets safety standards with certified radon testing for job sites, multi-unit developments, and final inspections.


Radon Mitigation
We install custom passive or active mitigation systems during construction—code-compliant, discreet, and builder-approved.


Radon System
Closing on a new build? We professionally activate passive radon systems to ensure safe radon levels and compliance at handoff.

Radon System Activation
Even with RRNC in place, testing for radon after the home is built is a non-negotiable step. If a test shows elevated levels, we can immediately move to the next phase: radon system activation. This simple process involves:
- Installing a Vent Fan: A quiet, energy-efficient vent fan is installed into the existing PVC vent pipe.
- Adding a Monitor: A u-tube manometer is placed on the pipe to provide a visual indicator that the fan is operating correctly.
- Post-Activation Testing: A final test is conducted to confirm the radon removal is successful, and the levels are well below the EPA's recommended action level.
This transition from a passive to an active radon mitigation system is a straightforward and cost-effective way to ensure the home’s indoor air quality meets the highest standards.
Frequently Asked Questions
1. Why do I need to test for radon if my new home has a passive system?
A passive system doesn’t guarantee safe levels, and the only way to know if it’s working is to test. The effectiveness of a passive system can vary based on local radon zones and soil conditions.
2. How do new construction radon services differ from services for older homes?
New construction services are more efficient and affordable because the mitigation system’s core components are built into the home’s structure. In older homes, these features must be retrofitted.
3. Is it more expensive to add radon services during construction?
No, it is significantly more affordable. The cost of a passive system is minimal compared to the price of a full-scale mitigation system installed after construction, and it’s a great value-add for health-conscious home-buyers.

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.
