Client Feedback
Szielenski Electric delivered flawless work on our office buildout. They were professional, on time, and the quality exceeded our expectations. Our entire team was impressed.
We've used several electrical contractors in San Diego and Szielenski is by far the best. They understood the unique demands of a restaurant build and executed without a hitch.
Award-winning work speaks for itself. Their control systems installation was complex and they handled every detail with expertise. I wouldn't use anyone else.
Had Szielenski install a Tesla Wall Connector and upgrade our panel. They pulled the permits, coordinated the inspection, and wrapped up in a single day. Couldn't ask for a smoother experience.
They did recessed lighting throughout our entire first floor. The layout looked great, the finish work was clean, and they left the house spotless. Highly recommend for any residential work.
Fast response, fair pricing, and the work was done right the first time. They wired our jacuzzi circuit with all the proper GFCI protection and had it ready for our backyard renovation deadline.
