Quick phone response. After calling they did come out and the electricians were there waiting for us. They replaced the fuse box and outside service and brought it to code. They cleaned up behind themselves too. The work was done quickly and we felt we were only being charged for work that was needed- no hidden extras and no unnecessary repairs or replacements. Thanks!

Kozen T.

I called STS Electric for an emergency electrical situation at my home. In my experience, I could not have done better. STS management, technicians, and office personnel are extremely knowledgeable, skilled, and thorough. I highly recommend STS for all and especially emergency electrical issues.

Had STS Electrical come out to do a 200amp panel upgrade & multiple EV charging runs to my garage with charging station installations. They handled all the permitting, the installation looks great and passed village inspection with flying colors. The price was very fair and the workmanship was excellent. Would highly recommend Alex and his crew for any of your future projects or electrical needs.

Being first time EV owners, we had quite a bit to learn about the process of getting an EV charger installed in our home garage. Ana was very responsive and arranged for a same day in person consult. Our project manager, Sam, was both friendly and extremely knowledgeable, we appreciated that he took his time with us as we had many questions. After we decided to proceed, they scheduled us within the same week. Our electrician Francisco did great work and finished the project in one day. He even performed the drywall himself. Highly recommend this company!

⁠Sam is extremely knowledgeable, efficient, and hardworking. We have used his company multiple times now --- to install a new bathroom exhaust fan, to replace faulty breakers, to install all of our smoke detectors, and to reinstall a rewired light fixture and each time they've done great work at a fair price.

My STS electrician experience was fantastic, I had them come in to do a few different projects and they were great. I love how the communication (for me, from Ana) is clear, kind, and concentrated on my needs; I love how the guys who came (for me, Francisco and Juan) were talented, kind, listened to my concerns, and just plain got the job done! I'm getting these guys back to do more work, but for now I'll say: You're in good hands.

I couldn’t have had a better experience not only were they thorough they found so many urgent issues that needed to get repaired without breaking the bank.

STS Electric has been a life savior for me! Their electricians are attentive, friendly, and dedicated, always going above and beyond to address the customers needs. I called on a Monday, and was able to get 2 - 3 electricians on the job on Tuesday, the very next day and scheduled throughout the week.

They've done all my rewiring for me, and they do the job in a timely manner. When they work, they put plastic everywhere to make sure my belongings stay clean and not so dusty.

The supervising electrician, Sam, has been absolutely wonderful. He explains everything step by step to me in laymans terms that I can easily understand. Ana who schedules and deals with the finances is super nice and dedicated as well! And the electricians Francisco and José were also very communicative about what work they were going to do and ensured that all my outlets, switches, and new fixtures were located exactly where I wanted them to be with electrical code compliance in mind.

STS Electric is the type of business I know I can rely on in a pinch. Just a really great team with high quality workmanship. I highly recommend this company!

Response from the owner:Thank you so much for your kind words and for taking the time to share your experience! We're thrilled to hear that our team was able to provide you with the service you needed and that you found our work to be timely and considerate of your home. We always strive to go above and beyond for our customers, and it means the world to us to know our efforts are appreciated.

Super happy with the work done by STS Electric. I called first thing in the morning and they were able to be here by noon. I blew a circuit in the middle of the night and smelt burning. They were able to quickly identify the issue, separate circuits and run new wiring making me once again feel safe and secure in my home. Highly recommend!!!
