Crawl Space Radon Mitigation and Encapsulation
Protecting your home from the ground up.
As a leading Colorado radon company, we understand that your crawl space can be a major entry point for radon gas, moisture, and pests. Our crawl space encapsulation and crawl space radon mitigation services provide a holistic solution to these problems, creating a healthier and safer living environment for your family. We are experts in both residential and new construction projects, providing a permanent seal against dangerous soil gases and moisture.
Why Crawl Space Encapsulation is Crucial
Radon gas infiltrates homes from the ground, with crawl spaces being a common entry point due to exposed dirt. Simply put, if you have a dirt-floor crawl space, you are at a higher risk for elevated radon levels. But radon is not the only problem. The open ground in your crawl space can also lead to serious moisture issues, which can cause mold growth, structural damage, and poor indoor air quality. By properly sealing your crawl space, you address all of these concerns at once.
Our Services for Crawl Space Radon Mitigation
Our expert team installs a complete vapor barrier system designed to seal and stabilize your crawl space environment. Each system is engineered for your home’s specific layout, ensuring effective radon reduction and long-term durability. Beyond mitigating radon, encapsulation adds measurable value, helping regulate temperature, lower energy costs, and create a cleaner, more comfortable home. With professional installation and high-quality materials, Better Colorado Radon delivers results that last.
Complete Crawl Space Protection Starts Here
Our vapor barrier systems are engineered for lasting performance—reducing radon levels, preventing moisture damage, and improving energy efficiency.
For Existing Homes
We begin by thoroughly cleaning and preparing your crawl space. We then install a heavy-duty, reinforced polyethylene liner that creates an airtight seal over the entire dirt floor and foundation walls. This professional-grade liner acts as a barrier, preventing radon gas and moisture from entering your home. If necessary, we can also install a depressurization system under the liner to actively draw out any lingering gas, making it a comprehensive crawl space radon mitigation solution.
For New Construction
Integrating a vapor barrier and crawl space encapsulation system during new construction is a proactive and highly effective strategy. By including this from the start, we help builders create homes that are healthier from day one. Our professional installation reduces on-site time for other trades and ensures the system is built into the home’s framing, providing a seamless and long-lasting solution that protects future homeowners.
The Benefits of a Sealed Crawl Space
Encapsulating your crawl space offers much more than just radon protection. It’s an investment in your home’s long-term health and value.
Improved Indoor Air Quality
A sealed crawl space prevents soil gases, mold spores, dust, and other particulate from circulating into your living spaces.
Energy Efficiency
A properly sealed crawl space acts as an insulation barrier, reducing drafts and lowering your heating and cooling costs.
Moisture Control
By preventing ground moisture from entering, you significantly reduce the risk of mold growth and structural damage to your home’s foundation and floor joists.
Pest Prevention
An encapsulated crawl space is no longer a hospitable environment for insects and rodents.

Happy Customers
Kelly DonahueTrustindex verifies that the original source of the review is Google. I feel so blessed that Better Colorado Radon, owner Ryan Osborne, came to my house and submitted a quote to install the radon system and reline my crawl space. I had (3) other companies submit quotes, all wanted to go through my closest and adapt the fan on the exterior of my home. Also, none of these companies felt that the plastic in my crawl space needed to be replaced? Ryan surveyed my property and explained the best possible resolution for my home. He recommended we reline the crawl space and install the unit in the garage. Once his team arrived I knew this project was going to be seamless. Very professional, attention to detail, informative and just a pleasure to have around. I now feel an incredible amount of "peace" in the air I breathe in my home. Because I know the job was done right. Thank you so very much! Aminta LuceroTrustindex verifies that the original source of the review is Google. We were in a tough spot with a radon system that another company just couldn’t figure out—right before closing on a home sale. Thankfully, Ryan and his team stepped in and completely saved the day. Not only did they diagnose and fix the issue quickly, but Ryan was incredibly communicative throughout the entire process. His response time was seriously impressive, and he made a stressful situation so much easier to manage. I highly recommend this company to anyone needing radon services. Professional, reliable, and truly above and beyond! Kailee AckermanTrustindex verifies that the original source of the review is Google. Better Colorado Radon has been a pleasure to work with. They were actually recommended to me by another large prominent radon company in the Denver area to assist with a smaller project I encountered with a client's real estate transaction. Better Colorado Radon was so responsive, did quality work, and charged a very fair price that I ended up hiring them for a full system install on my personal property. They will be my go-to radon mitigation company from now on. Eric LoveridgeTrustindex verifies that the original source of the review is Google. I had to replace our sump pump that was combined with our radon mitigation system in a sealed floor cavity in our basement. For a reasonable price, Ryan from Better Colorado Radon came out and replaced the pump and resealed everything, and even put a new cover on it to replace the old wood cover. If you have a sealed system, don't mess with replacing it yourself, give Better CO a call. Johnny DoeTrustindex verifies that the original source of the review is Google. Radon readings in my basement ranged from 4 pCi/L in the summer to about 9 pCi/L in the winter. My OCD finally got the better of me, and I began looking for a good outfit to mitigate. I got a few quotes and then found Better Colorado Radon thanks to Google. Always fun, right? I liked what I read and requested an estimate. Ryan got back to me within 24 hours (a good start) and we arranged for him to come and take a look. Came out right away. Impressed me immediately (not easy to do...) with his knowledge and I believed that he'd do a good job. He came out yesterday and I must say that his work, attention to detail and craftmanship exceeded my expectations. I was quite simply blown away with the results. I've attached some before and after pictures of the work. You can see why. I had the same work done on a previous house, and while the results were good, I could tell that they did the minimum needed. Ryan did the opposite. He even noticed some slab dirt around the basement tub drain, and went to Home Depot to get some sealant. That is professionalism at its finest and another great example of his making things as best that he can. Reading were 9.4 pCi/L yesterday. Just over 24 hours later? 3.8 pCi/L and dropping!! (Yes, I have a digital meter...) So, if you are looking for radon mitigation, look no further. Call Better Colorado Radon. You won't be disappointed. On the contrary, you'll be thrilled. Great work, Ryan!!! Mark W. 7/29/25 update. Reading is now 1.18 pCi/L and has been since a week after installation. THAT is amazing. If that's what you are looking for, give Ryan a call. Kyle bradleyTrustindex verifies that the original source of the review is Google. Prompted, efficient and friendly service. Tyler MartinTrustindex verifies that the original source of the review is Google. Teddy was very professional and knowledgeable. He ensured the system was effectively installed without being aesthetically intrusive. The job was completed well within their estimated window and was the best price in town! Cannot recommend Better Colorado Radon enough! Christian DuceyTrustindex verifies that the original source of the review is Google. Great company. Great work. They are on time and professional.
