Cello Electric

Cello Electric takes on electrical jobs around Concord, California. They run panel replacements, swap out old knob and tube wiring for code compliant lines, add GFCI outlets in bathrooms, handle grounding fixes on existing outlets and install Nema 14-50 outlets for vehicle chargers where the wiring is already in place. Matt shows up for most of the estimates and lines up the crew, while Kevin and Byron handle a share of the wiring and outlet work once the job starts.

Homeowners call them for panel upgrades that had been delayed, full runs of new wiring to clear out remaining knob and tube sections, bathroom GFCI outlets meant for bidet seats and quick charger outlet hookups on pre-wired spots. In some cases the crew finishes the panel and wiring jobs in a short window after the bid, pulls permits without extra delays and leaves the site clean. Other calls involve simple outlet additions or grounding that run into scheduling problems or higher than expected costs for the time actually spent on site.

They answer requests with quotes over the phone or through video checks on existing wiring, then book appointments during normal daytime hours. Response can be fast when Matt confirms the details, though some customers report missed visits even after multiple confirmations and no follow up calls. Pricing shows up as flat quotes for each outlet or panel section, and the work stays inside the Concord area without mention of farther travel.

Reviews give them a Google rating of 4.7 from 95 reviews and a DIRT Score of 4.4. Common notes cover quick wiring and panel jobs by Matt, Kevin and Byron alongside complaints about no-shows, costs on short tasks and occasional quality issues after the crew leaves. DIRT Score 4.4 from N reviews on Finds.

“Electric Heroes were great ! Matt came out right away , gave us a good bid for a new updated panel and was able to fit us in quickly. Matt and his crew were reliable, got the permits quickly and a job that we had put off way too long was finished quickly . Matt was a good communicator and a lovely person . Highly recommend! We have already given his name to a friend who also had a good experience.”

“Kevin and Byron did a great job replacing some remaining knob / tube wiring left over with code compliant wiring. They were quick. Highly Recommend.”

“I just needed some grounding work to be done for a few outlets. Scheduled for an estimate multiple times but no one came home at the scheduled time! I got hold of someone named Matt and he gave his assistant details again, talked to her to confirm on an appointment yet no one came home after confirming multiple times from my end. I haven't even got a return call or message about this.”

“I hired Electric Heroes (EH) to put up two GFCI outlets, one in each of my two toilets, so that we can use a toilet bidet seat. I had sent out a request on Yelp, and many companies with good reviews felt that a heating bidet would require a dedicated line and so they would not install one in a condo. Electric heroes and only one or two others responded. Only EH gave me a free virtual estimate of $760 for the job, $380 for each toilet. The estimate did not include the patch up job that would be required; I could hire a handyman myself to do that later. Little did I know that it would be a real horror! (See attached photos) I finally hired EH. They did come on the scheduled day, took about half an hour to tell me what they would do, and also verified using a meter that the bidet would not require a dedicated line. Anyway, he said that he would require to make about 8 holes in one toilet and 6 in the other and that there is no other way to do this job. Well, he was a real nice guy and I agreed. After he was done, we were rather shocked to see the large number of gaping holes. Well, since this is the only way it can be done, I paid them and then hired a handyman again through Yelp to help close the holes. He arrived and told me (he does electrician jobs too) that EH had really made a mess and spoiled the wall. They had drilled a hole at every slat point so that they could in turn drill a hole through that slat to pass a wire. He said that he had drill bits up to six feet long so that with just three and two holes (respectively), he could have finished a job. He also showed me a video where he created only five holes to pass a wire from one end of a living room to another via a roof. He also said that for $760, he would have even patched the holes and painted the wall, not just done the electric work. Anyway. I had to pay $540 to do the patch work and painting. So the total cost of the job came to $1300, $650 per outlet!”

“I put up a request in yelp for car charger Nema1450 outlet installation which was already pre-wired. Electric heros sent me a quote, called my and checked the pre wiring through a video call and finally scheduled an appointment. They said it would cost $350, which I thought was too expensive. But since the reviews were good, and didn't want to take risk with installing myself, I took the offer. They arrived on time and installed quickly. It was a 5-10 min job and charged me $350. I also asked if it was a industrial grade outlet and he said yes. Now it's been a year, and recently noticed that the charging has stopped. I was also not able to unplug the connector. I tried to unscrew and noticed that the outlet has melted. The outlet does'nt look like it was industrial grade and it was some cheap $15 leviton outlet. I regret getting it installed with electric heros. Charging $350 for a 10 min job, I atleast expected a quality product being used. This is so disappointing, and would not recommend Electric heros who wants quality and peace of mind.”
