Lords Radon, a Greeley contractor with a 4.9 rating from 64 reviews, frequently receives praise for punctual service, clear communication, and reasonable pricing for radon mitigation installations and inspections. Customers note that technicians are professional and thorough, often completing work ahead of schedule while maintaining a respectful demeanor. One low-star review criticized the company for recommending an expensive additional unit after an initial fan replacement failed to lower radon levels sufficiently.

He know exactly what to do and where to look. He is the one who installed the system way back when. He was friendly and enjoyable to have take care of the Radon system and give me the followup kit. He explained where to put the card and the kit he gave me explained the what and how and when to put the kit. I have it hanging from a ceiling light in my basement family room and the windows and doors are closed as instructed. Just waiting to get the results which will be what it should be.

Jay did excellent work installing the mitigation system at a very reasonable price. He cleaned up nicely after the work was completed. He is very courteous and professional at all times even though the layout of our home proved to be a challenge and he stuck by the quote he had provided. I will recommend Lords Radon to anyone that I know who owns or may be building a home. Best service guaranteed!

Both Jay and Jessy were professional and considerate in doing the assessment, providing an estimate, and completing the mitigation process. The price was reasonable and the work was done in a prompt manner. I appreciated the fact that Jay worked with me in this whole process, during the time I was involved in chemotherapy.
