The two installers from Colorado RadonMitigation were there most of the day and the system seems very solid. I am happy that the fan used was not loud to be invasive to the surroundings.

CRM responded super fast to my inquiry and had a tech out here a couple days later who tested our radon levels. They were super high at 24+. CRM came back and installed the mitigation system in a professional manner and got my levels way down. They came back to test again and the level was still a little high at around 4 so they worked with us to figure out a plan, installed a bigger fan, and got my number down to 2! I have 4 kids in my home and feel like I can rest easier now. Thank you CRM!

They did a great job updating our 29 year old radonmitigation system, bringing it up to current standards. The work was neatly done, and they listened to my request for a slight modification to the system.

The team at Colorado RadonMitigation did a great job completing this project, especially given they had to work through some challenging surprises when drilling into the foundation. The team left the side clean, and they were super friendly to work with. Best yet, we saw an immediate reduction in our radon levels (to about 0.5 pCi/L) which gives us huge peace of mind.

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
We are competitively priced relative to the local area and industry as a whole nationally. We happily offer realtor, builder, Veteran and repeat customer discounts!
We provide free in-person assessments within the greater Denver area and along the Northern I-25 corridor. Mountain and Plains communities will require a small trip charge if an in-person assessment is necessary which will be credited back should you choose our services.
Standard sub-slab radon reduction systems where a sump pit can be retrofitted start at $1.2k with more complex systems that require more powerful fans and multiple suction points to achieve the lowest radon levels possible ranging upward to $1.8k+. Total crawlspace encapsulation and sub-membrane radon reduction systems typically start at $1.5k depending on the size of the crawlspace.
All of our systems come with a post-mitigation measurement included per AARST standards!
What is your typical process for working with a new customer?
We will discuss your requirements over the phone and schedule a convenient date and time to visit the property to do a full walk through (if necessary) and design the system with the property owner's or builder's input. We will be able to discuss any preferences and any (observable) challenges up front and how that may change the scope of work and pricing. We promise to be as upfront and transparent from the beginning which will be reflected in our follow up quote on the day of the assessment.
What education and/or training do you have that relates to your work?
Our team is fully certified through NRPP and licensed for radon measurement and mitigation through DORA. We are proud members of AARST and work to the highest national standards set by them.
