Gage did an awesome job installing a custom radonmitigation system in our home. Great communication, timely, took great care and expertise in installation, and for the right value. He treated our home like his own. Thanks Gage!

I hired Custom Radon Solutions to fix what a previous company didn’t do properly during my house radonmitigation. Gabe came on the day that worked best for me. He communicated well about when he was coming. He checked for additional details that might not have been done correctly, beyond what I knew. He listened to what I said needed to be done because of the high winds I experienced last winter. He problem-solved even beyond the original problem and the space he had to work with. The project turned out to be complicated. His manner was courteous and warm. I’m very happy with the end product and would recommend him to anyone. His price was very reasonable.

I contacted Custom Radon Solutions on Memorial Day, never expecting to receive a call until the next day. Gage called me immediately and told me all about their RadonMitigation services. I live high up in the mountains and was concerned they would not come that far, but he assured me they do. When the technician, Jesse, arrived, he explained everything he would be doing. Jesse was AWESOME! So kind and so efficient. Before he left, Jesse explained very thoroughly how to do the follow up home test kit. What a great company! I highly recommend them if you have any radonmitigation needs. Thanks Jesse and Gage!

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
Pricing can be provided over the phone or made during a free in person consultation. This is left to the customers preference. We do offer price matching against bids from other certified, licensed and insured contractors, and we do offer discounts for first responders and veterans.
What is your typical process for working with a new customer?
Our team will immediately make contact with you via text message, usually just minutes after receiving your intake form. If you do not respond, we will call you the next day. From there, we decide your preference for being quoted (over the phone or in person. Both are free. In person recommended.) From there, a formal quote is sent to your email and we will wait to hear from you about scheduling, price matching or any requested adjustments to the quote.
What education and/or training do you have that relates to your work?
We are fully AARST and ANSI compliant, certified under the NRPP (National Radon Proficiency Program) and licensed as radon mitigation specialists in the state of Colorado. Continuing education credits are completed every 2 years.
