Best Commercial Building Contractors in San Jose CA

Pfeiffer Electric is a class act company! For many years have been using their services and they always deliver. The best thing about Pfeiffer Electric is their people. Every technician is knowledgeable, dedicated, hard working, honest and cares! Where do we find that nowadays...
We operate an institution with several buildings and many pieces of critical equipment. Pfeiffer Electric has always been there for us; whether it's installing and outlet, test panels, install new service, drawings and calculations or provide with complete site power backup and working through the night, you can count on them. Thanks!

I called Delta Electric thanks to a recommendation from a friend. They responded very quickly, and located a fault that had developed in some original, '50s-vintage wiring in our home. They installed new wiring to replace the failed line that same day and for a very fair price. Derek and Devon were professional, efficient and did a great job cleaning up when they were done. I hope I don't need electricians again anytime soon, but when I do, I'll call Delta Electric.

Avant was one of the best electrical contractors I've ever dealt with. Brian installed a fixed generator to automatically provide power to our house during power outages. He was extremely responsive and was really great communicating during the entire multi-week project. Very professional, thorough, and diligent. I'd use Avant Electric again for any new projects.

Worked for this electrical contractor on their VMWare project...average at best. I have certainly worked for better, more organized contractors...other than efficient management, they also seemed to be having growing pains in that they did not have adequate amounts of functioning tools for their employees to use, cutting into production, requiring crews to share tools which other, better, contractors have plenty of. Would work for them again though if the opportunity presented itself.

Incredibly professional and they do quality work! I’ll definitely be contacting them for our next project.
