2.3k+ Very well. Guillermo promptly returned our phone call. Came to inspect the one detector we were concerned about. We discussed options of updating all 3 of our hardwired smoke detectors since new products add features. He gave us estimate, and when we said yes, he immediately went out and...
Electrical Connections LLCI have worked twice with J & G and they have done a great job both times. They are very responsive, give fair quotes, come when they say they will come, and do very professional work. A couple of months after installing the smoke detectors, they started going off for no reason. I called J...
J & G Electric Co IncThey have good customer service. There was one installer here doing the work and everything went well. The alarm is a really high performing system.

Dependable Electrical Service & RepairThe electrician showed up on time and got straight to work. Installed a smoke detector and a light that I had already purchased. He was very professional and got the work done quickly and cleaned up after himself leaving no mess. Great service.
Hawkins Electric Service IncIt was okay. There were things that they didn't go beyond. He told me that there was some problems with my panel box that prompted me to get further inspection.

"They did an excellent job of installing the new panel at a reasonable price. Also they had financing options that were same as cash. I was provided some options of circuit breakers and the price with the options. The differences in breaker were explained and the code requirements for my area was also explained and compared to other local code standards. I was able to customize the options a little bit based on my needs and I have more space in the panel if I have additional requirements. Going from a box from the 1960’s to a modern solution mad a lot of sense. The installation was smooth with only a short time without power. Throughout the process, I was well informed of the progress. My family was able to work remotely from home during most of the install without too much disruption. (Used cell phone for internet and laptops while power was off.) They even installed a monitoring system for me to track the electrical use of the house. Overall they did a great job and I am very satisfied."

"Don’t use the plumbing! Called to have Kohler toilet tank plunger repaired. Whole installation is $20. Labor is an hour at $80 so the price is $150, at most. No, they charged $450–BS! These guys are a scam. No prices and I told them to have the repair person call me before arriving. No call, no prices. And, then the repair person has the stones to tell me that everyone overcharges!! Let’s start with not using Beacon!!!"
