“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
