Recommended Customer Reviews

I called Tom at Momentum for a small electrical job. He was able to accommodate my needs for a quick, same day job. He came out and gave me a free estimate and within an hour, someone was on site completing the job. The electricians that came out were friendly, knowledgeable, professional and efficient. I would highly recommend Momentum Electrical Contractors for their service and high quality work.

Tom and his team have been working with us at Rudy's for several years. They are very reliable, do quality work and are always professional. We highly reccomend Momentum Electrical.
Rudy's Can't Fail Cafe
Emeryville, CA

I am very impressed with Tom and his crew. They're responsive, reliable, and do top quality work.
Update: Tom came over on short notice in an emergency. I cannot recommend him any more highly.

The folks here are wonderful. They were prompt with their replies, their bids were clearly written out, the workers were efficient and friendly, and everyone was on-time. The electrical work was for a very old house, and they were able to fix the problem without any issues. I will most definitely use their services again!

Nightmare in every way.
CSLB report is in, it is available anyone asking.
Our simple remodel, which involved picture lighting being installed, water heater and basic outlets installed, adding some basic can lighting and under cabinet lighting. Nothing too complicated or odd.
Under the supervision of a foreman with a serious drug problem, who due to human kindness shall remain nameless, Momentum's team pulled existing wiring our of our walls, removed existing outlets without rhyme or reason, removed wall switches, phone lines and cable connections.
Although drywall and ceilings were removed FOR MONTHS, the wiring often wasn't installed until after the walls and ceiling went in. Almost every day we would walk into our home and find holes in the walls and ceilings as the various teams under various ""foremen"" tried to figure out what had happened before them.
Despite many reminders, they forgot to put in the wiring for the kitchen under- cabinet lighting - this necessitated putting the wiring and control panel under our house in a damp crawl space and the switch in the cabinet behind the garbage disposal. BUT, they put in the wrong wiring and removed the whole wiring and replaced it with...wait for it...a second batch of wrong wiring. Now we have lighting, but the wrong kind. (We didn't know this until the end.)
In the end, Thomas Gellis, the owner, sat in our parlor, told us he would finish the job without further charge ( due to our ""pain and suffering"" ...his words) and send an independent electrician from another company to hook up and explain the complicated new remote system and return when the house was finished to complete the installation.
He also agreed to reimburse us for an outside second opinion to assure that the work was safe and assist in deciphering what fixtures and outlets were connected where.
The programming guy Greg from DiLuzio Electric came for two days and was supposed to come back when the house was in order. We now have light switches taped with masking tape to our walls.
Mr. DiLuzio says that their technician Greg was on his own time with a side deal with Thomas, although he was in a DiLuzio van and wearing a DiLuzio uniform. and had made the arrangement with an outside supervisor who does consult work. ... Mr. DiLuzio appears to be covering his rear...I don't know any business that has a staff member schedule a side deal with an outside contractor for the same business and use company resources for two days...but everything around this is surreal. He threatened to sue us if we contacted him ( documentation available upon request.)
Every single aspect of the job ""fixed' by the last foreman, Douglas, was tagged as either code violation or substandard.( Documentation available upon request.)
After seven months of jerry-rigging the job together we heaved a sigh of relief and contacted Thomas to coordinate the independent coming back.
We needed him to sign a release of lien and looked forward to ending the nightmare. The lien was not legal.
It was then that he called and told us he was demanding more money and was going to put a lien on or home. We were stunned. He claimed he didn't remember what he said. He acknowledged that we had been misled by Nathan.
No amount of good faith on our part, patience and understanding was returned. In the end, he acted the victim. He only showed up when there was a problem or we called on him. He often contradicted his staff. He was aware of problems for months and over 100 emails were sent.
Anyone involved in issues regarding the Nathan, Douglas , Thomas and Momentum please contact us. We will share emails , documents,and photos and need the same.
We are shattered and broken by this nightmare.
Update: a week later- kitchen outlets found to be faulty.
Update: Two contractors suggested the reason the copper wire was removed from our walls was to sell the copper for money ...one mentioned ( without prompt) that ""drug addicts often do this."" We have no idea if this is the reason...but there was never a reason given.
Update: One month later and the kitchen outlets seem to be connected
to one another- against code and without dedicated circuits. Can't use the oven and dishwasher.
Update- faulty wiring eliminated power to all bedrooms. office, hall, outside lighting. Even the inspector from the Contractor's Board refused to trip the fuses when he saw how they were wired. We are making the CSLB report available to ANYONE who asks.
Any layman will be invited to tour our home and see the report and damages. All emails collaborating this review are available upon request.

Ran into a last minute need for electrical work during a network refresh at one of our client site's in Oakland. After making a few calls to our colleagues in Sacramento, none of them were able to come to the bay area on short notice. Made several calls to electrical contractors around Oakland on a Friday, Tom was the first one to call us back and made time to meet us at the site for a walk-through the following Monday.
They were quick in generating a proposal and scheduling time to come complete the job. We were very grateful to find Tom and the team at Momentum Electrical Contractors. They did an excellent job, everything works and looks great, and maintained top-notch communication throughout the entire process from start to finish.
We will definitely be calling them again if the need for electrical work arises in the bay area again.
Thank you Momentum!

We started working with Tom and his awesome team at Momentum when we moved into our house three years ago. We needed a complete rewiring. From the estimate, to scheduling, to completing the work, the Momentum team was timely, smart, reasonably priced, and just great to work with. Since then, we have needed to call back for a few small jobs, and for assistance after a major storm. Every time, Tom has worked to fit us into his team's very busy schedule, and every time, the work has hit the same high standards as the first big ticket job. The proof isn't always how well someone does the first job, but how willing they are to help out with a small job. On both scores, we are so glad we have an electrician we can count on!

Even though the check was already in the mail, he started the process of a lien after 2 weeks of receiving the bill. Work with them at your own risk.

Tom was very helpful and offered solutions.
He explained how gfci's work and also told me about the NEC so that I could look up current codes.
Thank you Tom!

Last week I had a circuit blow in my home. I thought I could get the power back but I could not.
SO I went through the yellow pages, calling a number of electricians, hoping I could get someone to come look at my situation. Everyone wanted to help but they were all very busy and unable to help.
Finally I called Momentum Electrical in Oakland and talked to Tom. Over the phone he gave me some suggestions to try but still no power.
Tom told me that Momentum was very busy as well, but after I pleaded with him Tom was very gracious and said that he had a crew not far from my home and he have them come by my house ASAP.
Well within an hour, Douglas from Momentum Electric showed up at my home.
He looked at the situation, made a few checks and found the problem.
Douglas explained to me what I had overlooked.
I am very pleased with the way Momentum Electric, functions.
Tom was very helpful on the phone and even more generous with his offering of crew time.
Douglas was the consummate professional. Courteous, knowledgeable and friendly.
I was helped out of a tough problem by these guys and I will use their service in the future when I upgrade the wiring in my home.
Thanks Momentum Electric
