"We'd been worried about our aging electrical system and used Angi's to find a few companies to get estimates from. Omri came and gave us our free estimate. He was very thorough and took his time to explain everything to me and my grandmother. He let us know what the most vital upgrades were (replace and flip subpanel out of a closet, replace feeder wire from the main panel to the subpanel, and replace the outlets in the bathrooms with GFCI outlets). Omri sent us an estimate and because of his thoroughness and thoughtfulness we decided to go with CA Electrial Group 24/7. We were told it would take 2-3 days to get the permit from the city and that all of the work would be done in a day. When we received the quote, we accepted it (subpanel replacement and installation, feeder wire from main to sub panel, drywall repair, GFCI outlets, and pulling of the permit) and paid the $200 deposit) We were able to schedule the work to be done the following week. The day of, Ricky came & replaced the subpanel & worked with another worker to replace the feeder line. They both seemed very skilled and were very careful with their work. They took a lot of time to make sure that everything was done well and correctly and cleaned up everything. They had not been aware of the need to also replace the 3 GFCI outlets, as they do not have access to the quote. They replaced them nonetheless, though. Benito came in the next day to complete the drywall and stucco patch work and painting. They all did AMAZING work! The only areas of confusion came down to the city permits & timing of the job. Upon our initial meeting, we had been told that the work would all be completed in a single day & that the company would handle the permits. After all of the electrical work was completed on day one, we were informed that the drywall work could be scheduled whenever we wanted it. We spoke with Omri again about the original discussion about the job taking just a single day and he apologized and scheduled the drywall work for the next day. What we did not know, though, was this meant that we could no longer have the city come inspect the work in order to get the permit as all of the work had now been covered up. Before paying the bill my grandmother wanted to make sure that the city would be coming in to complete the inspection, as we had discussed both prior to the work being done and while the work was being done, but we were then informed that if we wanted a permit, we would not only need to pay an additional fee (city fees - not mentioned in the original discussion) & have to have the drywall cut out and replaced again. It may have been an issue of miscommunication, but it was a bit of a frustration and left my grandmother feeling a bit worried about being up to code and feeling a bit upset about the whole project. Omri did everything he could to make it right and to work around our schedule to get the inspection and new work done, so we do appreciate this, but wished this had all been made more clear from the getgo. Overall, the work they do is fantastic, but would highly suggest that you keep track of everything discussed as many details seem to fall through the cracks. * It should also be noted that the company changed the quote after the fact to include the new fee that had not been discussed in the original meeting and quote. The original quote we received on 7/9 had charged us $0 for pulling the permit, but we can no longer access this version of the quote as they changed it on 7/19 after my grandmother had requested a copy of the permit."

Hi my name is Trevor Smith and I am a California state certified Electrician. I have over 15 years experience in Residential, Commercial and Industrial electrical work. I have been trained by the union and I am a member of IBEW in good standing and am looking to help you with all your electrical needs: Troubleshooting fans, cans, spas, grow rooms etc no job to small. Same day call back Same day service I am willing to work with you on the price and I will do work for trade. Contact today for more information!
"Beware, Trevor is extremely incompetent and a complete rip off. All we needed was a simple 240 panel swap First he gave us a price to start in 3 days and a price to start in 5 days for 6k more. This was on a formal written quotation. We chose 3 days because it was an emergency. He ended up ordering the wrong panel and by the time the replacement was delivered, we were at 7 days. He still charged us the additional 6k. Next, the 2nd panel had a connections approximately 12" further than the original panel. Without quoting or even indicating that we would have to pay for this he replaced a few feet of 100 amp wire and added $4200 to the invoice! The best one is the $1500 he added to "determine which phase the stinger leg was was supposed to be on." He checked alright by process of elimination. He guessed wrong and caught my office on fire! What kind of person has the nerve to charge for that after setting your building on fire. We ended up withholding payment on the last 2 charges to get clarity from him about their legitimacy. He showed up at our business very hostile and started screaming about giving him his money and what he would do if I didn't. He had already been paid the 19k on the original estimate. He would not listen to anything or leave and ultimately I had to threaten to call the cops to get him out of there. This guy is a scam artist and a safety hazard. Save your wallet and your building and hire someone else."

Subcontracting services FAQs
One starting point to find a local home builder is to collect suggestions from friends and neighbors. However, it’s still wise to do some more research before you hire a builder. Read reviews to supplement any word-of-mouth recommendations. Check sources like Angi that have standards and criteria in place to screen the pros it lists can also help you find more reputable local home builders.

Qualified, licensed electricians will charge from $50 to $100 per hour. The cost to hire an electrician for emergency visits may range from $100 to $200 per hour because this urgent service usually takes place during off hours and may require an electrician to leave or reschedule jobs they’re currently working on. Scheduling work on holidays or during periods of high customer demand, like after a major storm, will also lead to higher rates or extra fees.
