Keith Vigil clearly explained details of the project to me, Sandra in the office was always there to field my questions, the demo and siding crew were hard working and pleasant under the guidance of Edwin's daily presence, and Oswald faithfully and capably handled any finishing touches to the project. This is a five-star company with devoted and talented employees!"

"Drennen fixed a faulty radon system in our home. They took a look at what was going on and were very straight forward and honest in their approach. Every employee from the office manager to the installers exhumed care and professionalism at every step. They were extremely pleasant and kind. It was very evident that they cared about their customers and doing the job right. They also installed a radon mitigation system for my elderly father and the first thing he said when I talked to him was how nice the installers were and what a great job they had done. Both of these experiences demonstrate an integrity and honest care that is hard to find these days in any profession. I am truly grateful for Drennen and will recommend them to everyone without reservation."
