Aarmond is the man! He came out for a short, but thorough estimate and we came up with a plan together that ended up being simple, but effective.

Aarmond was great to work with. Professional, efficient and done on time. I highly recommend for radon services.
Couldn’t be happier with the work Aarmond did!! I chose Aarmond based on the other reviews here and they were spot on! IMO, it can be difficult to find people that take pride in their work, and when they do they typically do much higher quality work than those that don’t. Aarmond definitely takes pride in what he does!!

My New house had a passive radon system and the radon levels in the basement were very hight so Northern Colorado Radon came in to add the fan to make it active mitigation. After installing the fan, the pressure was low due to the existing passive system which was…

I would highly recommend Northern Colorado Radon. My New house had a passive radon system and the radon levels in the basement were very hight so Northern Colorado Radon came in to add the fan to make it active mitigation. After installing the fan, the pressure was low due to the existing passive system which was not set up correctly. The installer went over and above expectations to fix the issue with the existing setup to ensure proper operation. It has been working great ever since.

Wonderful company, the owner personally came and installed my system, he was very friendly and helpful. During the quoting process they were the only company to even ask if we've had a passive system already installed and helped me find it. Very afforable too. Radon levels are into a healthy range in 24 hours after adding the fan and sealing the sump.
Super nice dude, very knowledgable, great price, very transparent. Quality and efficient work. Found, explained, and corrected the deficiencies left behind by the builder in our passive system. Way better price than some of the other quotes I received for the same services from other local companies. Definitely worth the hire.
Aarmond was amazing! Super professional, efficient, and explained things wonderfully. He was flexible with his scheduling so we didn’t have to miss extra work days and after he finished he spent the time to answer all the questions that my wife and I had about the entire system. Would definitely recommend to anyone looking to get more information about radon systems.
Armand was awesome, Ive seen a fair amount of radon install now and this is honestly probably the cleanest one Ive ever seen, and it was a somewhat tricky job. Great communication, timely work, fair price and an awesome dude! Big time recommend
