“This is a great company. From the first phone call, which was answered the same day, to a quick appointment for an estimate, to completion of the job was less than two weeks. Dennis and his crew showed up on time and were very professional and extremely respectful while in my home. The workmen were very efficient in completing the job, they are very knowledgeable and did not waste time, I don’t think they even took a break, except for lunch. I highly recommend Aspen Radon if you are looking for a reputable company to do your mitigation.”

“Extremely knowledgeable and professional. The owner is vastly experienced and oversees all jobs personally. We did compare to another and we’re happy to pay a tiny premium to have had the best.”

“Outstanding work and excellent results. Dennis was great to work with – he gave me good advice on radon and testing even before I contracted with him for the job. He and his crew were very responsive, showed up exactly when they said they would, and worked hard all day to get my system installed. All workers were polite and respectful of my property, they were very efficient and took care to make the external components as unobtrusive as possible. My pre-mitigation test results were around 7.5, and the post-mitigation test showed 0.3, which is at or below what is found in the outside air in my area, so the system seems to be working very well. Several of my neighbors have used Aspen for their radon mitigation, and all of them are very satisfied with the results. Prices are competitive with like businesses in the area.”Review By: William Lidh – Zip Code: 80904 Submitted: 05/01/2020

“We recently had Aspen Radon install a radon mitigation system at our home. Dennis was a pleasure to work with and submitted a bid to perform all work and materials to complete our job. It is not to often you find a company that is honest and you have no problems with the employees working in your home. I highly recommend Aspen Radon for your abatement needs and evaluation. Cheers to Dennis and his crew. No wonder the company has been around so many years. Kim H.
