California Energy Consultant Service

I just had my roof replaced by California Energy Consultant Service, and it was an A+ experience from start to finish! This company truly does everything right. Gary was our initial contact and handled the quote. His expertise was immediately obvious; he walked us through every detail of the project and offered great suggestions to help us get the most value out of the job. Everything he discussed lined up perfectly with my own research and actually exceeded local building codes. Once we signed on, Jamie took over as our behind-the-scenes coordinator, and she was amazing. She kept us informed well in advance of every phase, including coordinating the necessary inspections. Whenever I had a question, she answered it quickly and with a super friendly attitude. The crew, Oscar and John, were awesome as well. They kept me updated on their daily progress and always let me know what time to expect them the next day. Their workmanship was meticulous, and the finished roof looks fantastic. We actually used CECS about 10 years ago to replace all of our windows and doors, and they were outstanding back then, too. It is great to see a company maintain such high standards over a decade. They have my absolute highest recommendation!

I had an outstanding experience with California Energy Consultant Service from start to finish. I want to give a special shout‑out to Sales Consultant Gary Lee, who was meticulous, patient, and incredibly down‑to‑earth. I trusted him right away. He took the time to walk me through every detail and provided an excellent quote that made me feel confident moving forward. I had 18 windows installed, and the installation team was just as impressive. Rodger and Igor worked extremely hard during the first two days — focused, skilled, and respectful of my home. On the third day, Oscar and John joined to complete the project, and their craftsmanship and professionalism were equally top‑notch. The entire crew was punctual, detail‑oriented, and left everything clean at the end of each day. My new windows look beautiful, operate smoothly, and have already made a noticeable difference. I highly recommend CECS for anyone considering window replacement. Exceptional people, exceptional work.

I just had all the windows in my house replaced by California Energy Consultant Service. This job included 2 sliding glass doors and the modification of a garden window to a single pane window. I am so happy with my new windows! Felipe sold the job and provided compelling evidence that the new windows would help lower my energy bills. Tony performed the final measurements and provided me with options which helped lower the cost. He also kept in touch with me so I knew the status of my install. Alonso and Omar, the installers, were wonderful to work with. They installed the windows with great care and were even able to save my kitchen granite where the garden window was. They were punctual, professional, and left my house as clean as they found it. I would highly recommend California Energy Consultant Service.
