California Energy Consultant Service is Sacramento’s Trusted Window Contractor

A message from Thomas Pursell, 

If you’re in search of windows, doors, Solar, Heating & Air or other energy-efficient enhancements, you’ve found the right destination.

I am pleased to share a significant announcement with all my loyal customers. After careful consideration and almost four decades of operating as Werner & Son, I have decided to take a step back and extend a well-deserved endorsement to a prominent local industry leader California Energy Consultant Service (CECS). Having competed with CECS in the past, I came to appreciate their integrity, honesty, and the value they bring to the industry. I am confident that you will experience the same level of satisfaction with their services. I have recently retired and relocated out of the area, marking my exit from personal involvement in the industry.

I am thrilled to say they offer the same range of products and services, along with other energy-efficient upgrades such as Reflective Metal Roofs and Insulated Siding Systems! In addition CECS is a participating contractor with SMUD and PG&E, excelling in securing valuable rebates for their customers.

Feel free to reach out with any questions you may have, and we’ll gladly provide you with a competitive quote for your upcoming home performance project!
