Recommended Customer Reviews
Vicki W.These guys did a great job. I was having blow outs on certain circuits. They came in rewired my bath separate from my bedroom. They also dug into my electric panel, correcting wiring and cleaning corroded leads. They were professional and fast. I've had no trouble since their visit.
Josh G.The electrician showed up on time and installed 3 ceiling lights. The work was reasonable quality and he explained in advance that patching and painting weren't included, so all in all a good job.
When you ask them to come back and fix something,
if they are going to be no-shows,
it would be nice if someone would call and let you know,
instead of having you wait around all day for nothing.
Called Casillas Electric when my regular electrician was on vacation. Was having problems blowing GFI units indicating a power overload or short somewhere in the system. I scheduled an appointment with Joe and he came out promptly and diagnosed the problem. He said, ""a refrigerator should be on its own circuit and not on a GFI switch"". He set up a new circuit in my panel for my outside refrigerator which solved the overload problem. I later discovered that there was arcing in my electrical panel so I had to replace 2 circuit switches which has completely resolved the issue. I would use J Casillas again if I needed him.
At the time the service was done, I paid about $1300 for refurbishing of the subpanel in my home which I was assured was the source of the problem. I was quite satisfied with the work and the worker and all seemed to be well. I then recommended Casillas to my son for an electric problem in a convenience outlet in his home., The recommended repair was the same as mine: refurbish a subpanel for $1300. This seemed too much of a coincidence. A second opinion from another electric company concluded that the subpanel was just fine as is. The repair to the outlet was done for $200 by the second company. All of which led me to question did I pay for something I didn't need.
the service was very good, but $600 to replace 6 inches of copper pipe in less than an hour is pretty expensive.
We were very pleased With the workmanship and the cleanliness of the crew. They installed my electric car charger and I plan to use them for future jobs.
On time arrival, good workmanship, cleaned up afterward, reasonable price. Ticks all the boxes
Michael R.J, Casillas and his crew did an excellent job installing my electric car charging station at my home. I highly recommend them.
Olivia B.Would totally recommend!!! I had 14 recessed lights installed in my house and the lighting looks gorgeous!! Super modern and makes it look bigger. These guys were totally professional and the price is super reasonable. We plan to call them later for more lighting because they did an excellent job and also did a few other electrical things around the house that needed to be done. Our house looks great thank you guys!!
