I am so impressed with the excellent and prompt service we received from Evan Bateman at Citadel. He was very informative, knowlegeable, supportive, and patient with the many questions we had. In addition he was not pushy, which I experienced with other companies. I will definatley call them again when are ready for solar.

Just a quick note to tell you how much I enjoyed working with you and your crew. You made this whole experience very painless for me and kept me well informed and up to date on all aspects. Also the crew headed by Juan were so easy to have around the house and were considerate of my needs and they worked under extreme circumstances for most of the time they were here.

Citadel delivered! Everyone in the company was pleasant, professional, and upbeat. Having a project coordinator really aided with communication. No project requiring this level of coordination is problem free, but when there was a problem, it was handled well and in a timely manner. Megan was with us every step of the way. She definitely gets 5 Stars!

“We at DeNova Homes are proud to have developed such a strong working relationship on both Roofing and Solar for our projects with Citadel! We were honored to be Citadel’s first customer when they started in business. Competition and service in our industry is essential and Citadel from its inception has been a first-in-class with price, quality, and service! I am so pleased with Citadel I have even had them perform Solar and Roofing on my personal properties and office in addition to the majority of all our subdivisions throughout California.”
