California Energy Consultant Service

I can't say enough good things about CECS. Had windows and sliding door installed by them 4 years ago. Since then I had a couple of issues that needed to be addressed. Both times they responded to our needs rapidly and without hesitation. Outstanding customer service! I highly recommend them for your window and door needs!

Had a great experience with CECS. Lance was great to work with in deciding what I needed for my house. The guys that came out to install were fast, efficient, clean, and nice. I will definitely work with them again if I ever need anything else done.

I had never heard of this company until I sought out window replacement companies via Yelp. They were rated high so I chose them among 3 others to get a quote. They won me over by their competitive price and their willing to work with me throughout the process. In fact, they were the only company willing/able to complete the install of our windows within a very tight deadline (by year end). I would definitely recommend CECS to anyone in this region.

I was shopping for a new front door and by chance found this company. Very glad we did as we were able to get a high quality beautiful front door for a great price. Highly recommend using them for home improvement services. You'll be glad you did!

You can also see my review on Yelp. I am so pleased with my new windows. What a difference. The entire experience was so pleasant and so professional from beginning to end. The installers worked so efficiently and harmoniously together I hardly knew they were here. They cleaned up afterwards too (which I can tell you doesn't happen often anymore). I highly recommend this organization. Love my windows.

I wish I could give a 10 star experience. Not only do they do fabulous work and installs but they go above and beyond the call of construction (per say). Office staff and sales reps are very friendly and helpful throughout the whole process. Took the time to explain everything in terms that I could understand! Thank you CECS!

All the work was done as promised and on schedule. New windows, new insulation, and ducts sealed. The workmen were hardworking, conscientious and polite. The office staff communicated regularly by phone and email. The company applies for the SMUD and PG&E rebates so I didn’t have to. I am very happy with the work.

Highly recommend California Energy Consultants. Everyone from Gary to the installers to the office staff has gone above and beyond. Price was 30% lower than other bids. Even the city inspector who came out complimented the installation and asked for Gary’s card.

Company was very professional from beginning to end. One of my windows came in wrong and they addressed the issue immediately by reordering the proper design. I would highly recommend them and plan to use them again in the future. Thanks!

"California Energy Consultant far exceeded our expectations The siding was done by "Artists", true master craftsmen. The new roof was completed within 3 or 4 days and they put finishing touches on, on a Sunday! The house is so airtight now, over a 30% improvement of when we started. The windows and doors are beautiful, and what a pleasure it is to have screens. We have a brand new house to come home to!"
