If I could give ten stars, I would! APEX Radon made the entire process smooth from start to finish. John was great during the initial assessment, and Cheth went above and beyond with the installation. Cheth was professional, organized, and easy to talk to. His communication before, during, and after the job was excellent. He explained how everything worked in simple terms and helped me feel comfortable and confident about the system moving forward. That peace of mind meant just as much as the work itself. They estimated a few hours for the installation, and Cheth finished even sooner than expected. He truly underpromised and overdelivered! I’m grateful for the care, efficiency, and outstanding service I received. Highly recommend Cheth, John, and the APEX Radon team to anyone looking for a great radon mitigation experience!

I have used APEX Radon in 2 houses. They are prompt, knowledeable, fast, and professional. They did not give a a hard sell or try to add on stuff. They gave a free written quote. I recommend them!

I'm appreciative. 4.5 out of 5 only because it cost me a lot. To be fair, they were competitive with the other bidders.

Apex Radon has completed several installations for our agents at Brokers Guild Real Estate, as well as for my rental and investment properties. I also trusted them for my primary residence. Their pricing has consistently been impressive, with honest recommendations and no upselling.
