Recommended Customer Reviews

These guys are simply the best! Derek is SUPER responsive and a great guy. We had him redo most of our electrical and he was easy to work with, delivered great work at a very reasonable price. He also made recommendations on other things we could do to make the house/project better. Amazing.
Even better, we had a power outage and I called Derek because it was isolated to our house (as far as we could tell). Immediately the guys showed up and figured out it was an issue w/ the power lines and recommended we call PGE immediately....come to find out, there was an issue w/ the lines to the pole we couldn't see but impacted a few houses on the block.
Knowing there is an company like Delta around makes me know if I need anything they'll take care of me. I'd rate them a 6 if I could. Fantastic

Delta Electric just finished installing under the counter LED lights in my kitchen. What a great job Derreck and his two able electricians did! All were knowledgeable and careful of my cabinets full of dishes and condiments and even moved things around so I did not have to do much preparation before they arrived. I think the price was very competitive, however I have no idea since Delta was contracted via my usual contractor, Paul Carrillo, Construction. Thank you Derreck and the guys for brightening my day and my KITCHEN!!

Delta Electric installed recessed lights in my kitchen ceiling. They kept burning out and I learned they had installed the wrong kind of fixtures. The insulation in my attic was causing the fixtures to over-heat. I called within the month (one year warranty on this job) to report the problem. They set up a time to come over and fix the problem but never showed. I called back, set up another appointment, they never showed. After this, I couldn't even get them to answer the phone. They do not honor their warranties, so beware.
They did other minor work in the house and did a good job and the price was excellent. But beware of shoddy workmanship, and the warranty is a joke.

Delta Electric just completed replacing my breaker sub-panel, all my outlets, switches, and junction boxes, added GFI's and safety connectors for all my aluminum/copper wiring connections. They were courteous, on-time, and always advised me on their progress and plans.
Their bid was competitive, and they demonstrated clear knowledge about the best practices for safety in dealing with aluminum house wiring.
I highly recommend them and will use them again for any electrical work I need.

I recently used Delta Electric to upgrade the connections in my aluminum wired house to use copper connectors. I used the CPSC approved AlumiConn miniature lug connector. Delta Electric have done an outstanding job at a very reasonable price. They also upgraded the main electrical panel. They showed up on time, were very professional, and made sure I was very pleased and satisfied with the work.
They were very honest, and did not do unnecessary work just to inflate the bill. Michael always explained all the options available, before doing any work.
Derrick, Michael, Salvatore and Donna really strive for excellence. Its a family owned business, and they take pride in their work. I had a very pleasant experience working with Delta Electric

I love Delta Electric! over the years they've upgraded my main panel, installed dedicated circuits, and recess lighting/ all my friends are now using them.
Derrick is friendly, efficient, and great to work with.

OK. So I can't imagine having a better experience than the one I had with the guys at Delta Electric who replaced my electric panel.
A little backgound. The original panel from my 1968 house had failed and four different electricians told me the lines coming into the panel from PG&E were too short. New codes from PG&E require the meter be a minimum of 48 inches off the ground. The PG&E wires coming from the ground into my panel were supposedly too short to meet the new 48"" height requirement.
This meant I was not only going to have to pay an electrician to put a new panel in, but I was also going to have to pay PG&E to extend my wires (which would have cost an additional $4k).
Enter Delta Electric who managed to install the panel without PG&E extending the power lines. They did this with permits from both the City of San Jose and PG&E.
Oh. And the icing on top of the cake? They replaced the panel for $1,000 less than the next lowest quote. So if you add the expenses I saved by not having to extend the power lines, Delta Electric saved me about $5k.
Someone pinch me. :-)

When we moved to our new office, we needed electrician to wire our cubicles and add some circuits. Delta Electric worked with us to meet our budget. Derrick and his team came on time, finished the big job quickly and cleanly to our specifications. We highly recommend Delta Electric.

Everything started out OK... I called to make an appointment. Told them the story about how power went out in one of the rooms on my house and how I was using extension cords to power it. Got a same day appointment with a time window of 2-4 pm. Got a call at 2:22 that they were running behind and would be later. Told them fine and thanked them for the heads up. Was even told they would call and update me and keep me posted. 5:30 pm no call no answer no show. Called the next day and got voice mail and didn't get a return call. Thankfully I found another electrician on yelp BAY LIGHT ELECTRIC. They came out the same day and hooked it up. I won't ever consider using delta again.

I called Delta as our Garage door and Microwave both went out at the same time. Derrick and Michael came out, identified the problem and had it fixed in no time. They were easy to work with and tidied up after themselves.
They also recommended replacing our panel as its old and a safety hazard.
I will definitely be using Delta again when we decide to update our electrical panel.
