I launched this company in 1980 as a way to meet the needs of my expanding family, and I have never looked back. Seeing the rapid growth of San Jose, my wife and I knew this industry was the right choice, and we have been pleased ever since.

Recommended Customer Reviews

I don't write reviews very often, but I think it's important to let managers/business owners know when their employees stand out with exceptional customer service/performance. We're quite pleased with the process from start to finish...initial appt. with Derrick for an estimate (punctual, polite, and professional), receiving the quote in a timely manner (Thanks Donna), and exceptional workmanship with the electrical work and cleanup (thanks Michael and Salvador).
Thank you, Delta Electric, for a job well done!!!

The ceiling light fixture above our stairway suddenly dropped down due to a bent swag hook that had been bearing the weight of the fixture. It was the day before Thanksgiving and I was needing someone to repair. After calling multiple electricians, I spoke with Derrick at Delta Electric. Not sure why I did not reach out to him initially as we are neighbors, but thankfully, he agreed to come by. He wasn't available until early that evening, but I was impressed that he was even willing to come, seeing that it was the night before Thanksgiving. He, by far, is the most knowledgeable, professional, and courteous electrician I have had the pleasure to meet. Within an hour, he had accessed my attic in order to reattach the electric box, reattached my ceiling light fixture and installed a new swag hook. He is an incredible worker and we were so very thankful for his expertise. Five Star Service from Derrick at Delta Electric!

These guys are as good as it gets. I am very happy with the entire process of scheduling and the job performed. I needed help getting the team to make my home a smart home along with the installation of newer fans. They came in, single pole, installed 3-way and 4-way smart switches along with smart plugs. Derrick came along with Salvador and Michael and got the job quickly done, including installation of the dreaded neutral wire where required. There was nothing they could not do! Team was extremely professional, courteous and reasonably priced. I am extremely pleased with the job performed and will be using them for all my electrical needs in the future.

Delta's employees are more competent and knowledgeable than management. This seems like a situation where the electricians are employed to take advantage of managements license. They installed A new panel and circuit to support a hot tub. However, they failed to scope out the job correctly and were going put the circuit by the water outlet until one of the electricians caught it. They had to charge me more to move it but did not take ownership of the error so I had to split the cost. Also, management underestimated time required for installing low voltage backbone and hookup to existing LED's. Doubtful I would ever use them again.

This is a review that I never imagined I would be posting. We began with Delta 9 years ago when we bought our house. We did our homework, checked the reviews, the BBB, everything you can imagine. We have had them change lights, install ceiling fans, even upgrade an electrical box. That is when, unforturnately, 9 years later, our electrical nightmare began.
Three years ago, we asked Delta to change out an electrical box. Being a first time homeowner, we didn't know then the questions we should have asked. Delta disconnected the power (our first mistake), changed the box, and then reconnected the box (our second mistake). Delta told us they put in a temporary tie-in from the house to the pole (not allowed) and we were assured that PGE would be out to complete the work. Not so.
Three years later the temporary tie-in is still up. We have contacted Delta and talk to Donna several times about this, but nothing has been corrected. PGE has since told us that Delta was not authorized to disconnect and reconnect the PGE powerline, and that Delta never filed the proper paperwork with PGE to have it done correctly.
In August 2018 we had our roof done and the roofers were concerned about the safety of the ""temporary"" tie-in. We tried to reach out to Delta to get this issue resolved. Not only have they not responded to any phone messages or emails over the past 5 weeks (and there have been many), but the one time we finally got a hold of someone (it was Derrick), we were hung up on.
Due to the concern we have about the box and the amount of work they have done on the house, we will be taking our business elsewhere. And I strongly recommend that other people do so as well. Their professionalism only seems to extend to when things go right. And they do not follow the rules that PGE has laid out for safe electrical work. When things go wrong they do not stand behind their customers, leaving their customers to fend for themselves.

WOW! Amazing customer service! Thank you to both Michael and Salvador who came out and took care of the light fixture that needed repair. We were impressed by how they made sure to not damage the new linoleum that is in the kitchen. They went the extra mile to protect the linoleum and carpet as well. Extremely courteous, empathetic to our needs, and on time. We would recommend Delta Electric to everyone! THANK YOU!

Stay away from them - very rude and difficult to deal with. Would not do business with them again!

Delta Electric is the company we will use for all of our electrical needs from now on. I give them my HIGHEST recommendation. They are GREAT! Donna provided the fantastic customer service and actually got us on the calendar within a couple of days. Derick was scheduled to show up at 2pm. He called instead and informed me that he was stuck on 101 North because the road had flooded and CHP closed it. Said he would be late. Well they shuffled some things around because Michael and Salvador showed up just a little past 2. Michael was great he listened to our problems made a couple of suggestions based on experience. Then they went right to work. Wow! I thought they would have to come back with all of the items we needed and wanted done. They completed all of them that evening. We were very impressed with these guys and the expert professional work they did.

We had a very old breaker box that finally started having mechanical issues with the main circuit, leaving about a third of our house without power. I called Delta Electric on Friday and they said they could have someone out Monday to do a temporary repair and then they'd be able to replace the box itself in a couple of weeks.
Monday morning two very nice gentlemen showed up, took one look at our box, and said it wasn't even worth repairing and that our money would be better spent just swapping it out now. They quoted us a price that was lower than the averages we've seen for the same job, and then got to work. Later that day we had a huge new box, power back to the whole house, and they also fixed a couple outlets that had never worked since we moved in.
Quick, professional, and reasonably priced! I would highly recommend them and will be calling them again if we need more work done in the future.

Derrick is amazing. He came out and diagnosed, then fixed our issue in a matter of minutes, all with a great attitude. Great guy!
