Recommended Customer Reviews

I found Dave on Yelp and was completely satisfied with his work. I was very nervous about finding and choosing an electrician, but Dave took the time to explain everything he was doing and that gave me a lot of confidence. He rewired the outlets in my garage, installed a ceiling work light, and installed a motion detector light outside. The work was first rate!

I cannot express how lucky we are to have Dave nearby!
We bought a home in San Leandro a few months ago and needed an electrician to ""ground"" our electricity (older home) before our cable company would install the TV and Internet we can't live without. We searched Yelp and found Dave and since then, we called upon Dave again this past week to update the wiring and lamp in our garage, plus install a motion-detector light. Everything looks and runs like a charm!
Dave is beyond professional. He:
a) has a personality (gave us a great tip on a restaurant to try...which we did! And it's delicious!)
b) does impeccable work and cleans the space when he is finished
c) sets himself apart by being fair and direct!
Example: We asked him to provide an estimate to install a ceiling fan -- he actually asked to look at where we wanted to place it before quoting a price. He checked out the crawl space, if we had enough support to hang it, etc. And in the end, he actually suggested NOT using an electrician for the job and instead considering an attic fan.
Without any hesitation, 5 stars.
We're already trying to find other projects we need help with! ... I think a timer for the porch light might be next!

I called Dave based on all the great Yelp reviews and I must agree with all others that he is very talented, honest, efficient, hardworking professional and such a delight to work with. He has completely sorted out all the mess of home-made sub panel that was done by the previous home owners and organized and upgraded wiring in the utility room, installed a new light fixture and cleaned up the space so well that I could not believe it was the same room when I saw the result. His rate was very reasonable and he didn't charge anything more than quoted amount even though the scope of the work turned out to be much more, so I have paid additional amount as my token of appreciation. I would highly recommend him to anyone and will definitely work with him on any future projects.

Dave was very professional and the job was completed perfectly. He gave us several valuable suggestions on the project, and even performed additional work at no charge to bring the house up to code. His rate was more than reasonable, and he finished the job quickly and cleaned up the work site completely. I would recommend him to anyone!

Without a doubt, Dave is one of the most professional electricians I have ever encountered. Dave gave us a reasonable and complete estimate for recessed lighting at our home in Pleasanton and explained in detail the process of getting the job done during the estimate process. Another company wanted to charge us $69 as a fee for an estimate.
He worked with us to arrange the job quickly and on our schedule and called us the night before to confirm his arrival. On the day of the job, he was right on time, well prepared with all his tools and materials, and did a very professional job that we are very happy with. He even went the extra mile and checked with us during the course of the job to ensure that we were happy with his layout of the lighting. Moreover, he was meticulously clean during the work and even tidied up his work area prior to leaving.
All in all, highly recommended - will definitely call Dave when an electrician is needed!

I'll keep it short, but sweet. Dave was punctual and delivers on what he says he will for the quoted price. He is also fast, no drama and leaves no mess behind. He understands how to work with what is there if it is functional and safe versus just tearing it all out, very critical in an older house. Alan

Dave did a fantastic job on our house for a minor wiring upgade. He was very prompt (showing up two saturdays in a row on the dot at 9am) and very knowledgeable as well. He was more than happy to walk me through all the work he was going to do and take my input for the location of two new outlets. He charged $300 for the installation of a 240v plug (exposed in the garage and with a short run of conduit) and another $150 to add a second 120v outlet. Overall we were very happy with this work, speed, demeaner, and attentiveness. I'd highly recommend him.

The best electrician ever! I called Dave at Blue Line Electric because I was experiencing intermittent power outages to my kitchen outlets. He came within 30 minutes to do a ""Trouble-Shooting"", for which he quoted a very reasonable flat fee and spent almost 2 hours testing various things in the house (including crawling up in the attic) on that first day.
Because the outages were intermittent, our trouble-shoot was a very challenging task, to say the least. Dave spent a lot of time I can't say enough how patient and diligent he was.
Dave came to the conclusion that it had to be a problem with PG&E's line coming from the power pole across the street. He refunded the trouble-shooting fee and wrote a detailed explanation of everything he did and what he believed was the problem so that I could explain everything to PG&E or another electrician if I needed to go that route.
PG&E finally came and replaced all of the connections on the power pole and I believe the problem is now fixed (fingers crossed!). Nearly one week and no power outages.
Bottom line: Dave is extremely honest, knowledgeable (took lots of time to answer questions and explain what he was doing) fair and personable! He treats his customers like family, going above and beyond to help you. Not something you see everyday!! Highly recommended for any electrical job. You won't be disappointed!

I searched on-line to find an electrician familiar with older homes. The Yelp reviews for Blue Line Electric (owner: David Zhu) were spot-on. David was prompt, courteous and knowledgeable. Also, his estimate was very reasonable, and he stands behind his work for a full year. David will prepare the estimate and do the work too!
I called David on the weekend and he came out right away on Monday. After the walk-through, David provided me with some recommendations on how to deal with the old-fashioned chain light switches in our closets (notorious for getting stuck or breaking), and what the problem might be with a set of indoor / outdoor switches and sockets.
He worked throughout the 3 1/2 hours, even with the wet conditions, and showed me the parts he had replaced and explained how they were contributing to the problem. He was thorough to the very end, leaving no trace of dust in the closets - another bonus.
I would highly recommend Blue Line Electric.

We couldn't be happier with the work performed by Dave from Blue Line Electric. We have a 100 year old home, some of the electric wiring is original, and various non-electrician homeowners have ""updated"" in creative ways.
We called him because the electricity in two bedrooms went out. My husband and father-in-law worked on troubleshooting the problem all weekend and couldn't figure it out, so we knew it was going to be tough. Dave quoted us a very reasonable price to come out and fix it, and said he wouldn't charge at all us if he couldn't fix it.
He came in 30 minutes (we were just happy to have someone answer their phone).
Dave worked for over 5 hours, without giving up, in hot (attic) and frustrating conditions. The entire time he was cheery and friendly.
He troubleshooted the problem and ended up fixing a loose connection in an electrical box, that was on a neutral side of the iine (making it very difficult to locate.)
We found him extremely knowledgeable. It was a pleasure to talk with him and have him in our home. Couldn't be happier. We ended up paying him more money than he charged us.
