Five Stars for Oakwood Electric & Generator:…read more I had a serious electrical issue where the source of the problem was complex. I knew I needed the "A" team.. I am extremely grateful to Arvy at Oakwood Electric & Generator as he got right to carefully and methodically sourcing the problem and that wasn't easy because although my interior electric had an unknown cause of a dead short from over 15 outlets, Arvy found the source of the problem on the exterior switch on the porch that had burned. (Clearly very serious!) He also checked many other outlets and made sure I was going to be ok after the repair. Clearly Arvy and Oakwood Electric are the "A" team and I am very grateful to the smart efficient work but also for caring for my safety. I highly recommend Arvy and the team at Oakwood Electric & Generator in Westmont . Thank you!

We recently purchased a house in the 'burbs and there was some electrical work to be looked into /…read moreremediated. After reading all the reviews about Oakwood, I decided to give them a try and I'm glad I did. They first came out and provided us an estimate of the costs - which was good b/c then I knew which ones I would book immediately vs wait on. I then was able to schedule them to come out a week or two later for the work. I had quite the laundry list of items and they were here about 8 hours (1 to 2 people). At the end of the day, it was a costly day, but to be honest - not as bad as I expected - given how much I had them do. They provided me a source of comfort knowing that my electrical needs were being taken care of in a professional and safe manner. I thought the workers were really nice and did a great job. I would recommend Oakwood to anyone and I would use them again.
