Nielsen Electric
Company Overview
As the oldest contractor in Alameda, Nielsen Electric, Inc. began as a solo venture by Tom Nielsen during the challenging times of the Great Depression.
The business transitioned to Tom's son, Eric A. Nielsen, and his wife, Diana Traini Nielsen, in the 1950s.
The legacy continued as Eric and Diana's children, Eric Jr. and Sidney, embraced the family trade during their teenage years and still contribute to the business today.
Currently, Diana Nielsen Henneman, their granddaughter, works alongside her grandmother in the office.
At Nielsen Electric, Inc., we are experts in all kinds of electrical systems, especially those found in the historic homes of the East Bay.

The person working for Eric missed one knob and tube and installed the electrical using a white wire as return without labeling. He also used a salvage breaker box, and didn't clean up. If we could sue, we would've but it is awhile back. Eric himself is a very good electrician but his worker was bad and unreliable. (He even Stole food from us) I want to make the distinction that Sid, Eric's brother has fixed some of the goofs. But the company we hired later for another project ""cleaned up"" the breaker panel. All in all we spent a fortune paying people to re-do their work which was also pricey.

I had an appointment with these folks, I live in Alameda where this business is located, actually just round the corner so not much travel time for them.
No one showed, I called, no live person, an answering machine, left nice messages ( benefit of the doubt,) no replies, nothing.
We all get bothered by wasting an afternoon on service companies that don't show, however most call with an excuse or an apology. Not Nielsen Electric :(
This company has been in business for a long time, but I believe the ownership split and this is what's left.

I have used Nielsen Electric several times for a home we own in Alameda. He has always been very responsive, easy to reach and accommodating. And, he is a very knowledgeable electrician, and knows what he is doing. I have even called him on a Sunday morning, and he was at the home before noon, and fixed the electrical problem! His prices are reasonable, and for a recent, simple, over-the-phone walkthrough fix, he wouldn't charge even me. A real pleasure to do business with.

Power problem in one of the units, some outlets and lights quit working. Found that power only coming out of one side of main breaker, pulled it and found connections corroded and burned. Put it back, now no power.
It's Sunday, (Memorial day weekend), called Nielsen electric and Eric came and took a look. He went back to his place and found the pieces to replace in the power box. To make a long story short he fixed the connections, installed a new breaker and got all of the power working and it was still light out.
Thanks Eric for the reasonably priced fast and completed Sunday service.
Nielsen Electric was the only same day response of all the electricians that I called.
Nielsen Electric saved the day!

They came promptly and did a great job. We will call Sid the next time we have an
electric problem. We have rentals and it is nice to know who to call.

6 months after Eric solved another electrical problem for me, the power went out in another apartment. I called Eric and he came out in a couple of hours. The problem was caused by a leak that corroded a connection and circuit breaker. He fixed it in the rain and told me to caulk the hinge above the breaker door. Eric saved the day again. He is good at troubleshooting problems and his rates are very reasonable.

I was looking for an electrical contractor and chose Nielsen Electric because I wanted a company that was in Alameda which is where we live. Nielsen Electric's website, was very impressive, a family owned business that goes back 75 years, passed down through the family, all born and raised in Alameda. I called and made an appointment on Friday, 1/8 for an estimate. Eric Nielsen showed up right on time, seemed like a nice enough guy. We had a home inspection report, which made things easier for Eric to see where the problems were. My husband who also grew up in Alameda and knew the family name, walked around with Eric discussing the repairs needed and everything seemed fine. Eric was supposed to get back to me on Monday 1/11 with a proposal, today is 1/19. I have made several calls to the number he lists on his website, no answer, no recorded greeting. I have sent several emails with no reply. The family history on the website is true, however, Sidney ""Sid"" Eric's brother, does not work with Neilsen Electric in Alameda any longer, even though it appears that he does. I did a little research and was able to locate Sid Nielsen, S.J.N. Electric in San Leandro. I gave him a call, he said that he would ""make it right for me"" He is coming out tomorrow...Look for my Yelp review for S.J.N. Electric in San Leandro, I'll let you know how it worked out.

I see some have had similar experiences... Nov of last year, i contacted them via their website's ""contact us"" feature. They simply never contacted me. On 10/21/15, exact same thing. Put in a request for a quote, not a response, email, text message etc.....
People may say ""pick up the phone and call them..."" I say ""NO"". I don't like the phone, and, if they didn't want to offer electronic communication, they should not make it available to the consumer. If they aren't interested in the work, simply say so.... Thx

I called Saturday morning around 10:30am and left a message. I received a call back from Sid within 30 minutes. He walked me through some trouble-shooting on the phone and suggested I call the power company -- turns out, it was on the power company side and it was completely resolved within three hours.
He was kind and generous with his time and knowledge. If I have future electrical needs Sid will be the first one I call.

We recently had Ron return to do some electrical work in a bathroom and to install a new light fixture in our patio. He was thorough, knowledgable and a very agreeable person. We've used Nielsen Electric many times over the years and highly recommend this Alameda company.
