Electrical reviews in Long Beach, California

Excellent installation of the Tesla Wall Charger! I currently have a 6-50 outlet in one end of my garage. The crew extended the outlet to the front of the garage using emt conduit and hiding it as much as possible above my garage cabinets with professional results. It took a little over 2.5 hours to complete the job and in the end I was quite happy with the end product. Excellent communications from start to finish!

Excellent work! I am astonish to the utmost respect and professionalism that Mr. Jonathan Polanco and his colleague has provided to me when installing a new electrical outlet. They are very knowledgeable. They work very clean. Removed the small debris afterwards. I am very very satisfied. And, I highly recommend Mario Castillo Electric for any electrical services.

Totally recommend Mario Castillo Electric. We had a new panel and sub panel installed. They did great work and always kept in contact with us. They were friendly, very knowledgeable and professional. Everything passed inspection with no issues. These guys know what they are doing. Shout out to our techs, Rudy and Aaron!

Luciano was easy to work with when getting the quote. Salvador and Aaron were friendly, professional, and a pleasure to work with. Salvador took the time to ensure everything was placed where we wanted and even pointed out issues from previous work so we could better understand the situation. Despite being quoted about 2 days for the work, they stayed a little past their time to finish up same day. I plan on reaching out to Mario Castillo Electric for future projects.

Rudy and his crew were exceptional. They were knowledgeable and efficient. The job was completed as stated and the site was left very clean. I would highly recommend Mario Castillo Electric.

Here’s a draft for your review:

I recently had Geo, George and Edgar from Mario Castillo Electric upgrade my service panel and install an EV charger, and I couldn’t be happier with their work! From start to finish, they were professional, efficient, and clearly experts in their field.

The service panel upgrade was seamless, and they took the time to explain everything they were doing, which I really appreciated. They ensured everything was up to code and handled the process with precision and care. The EV charger installation was also flawless.Geo George and Edgar made sure it was placed in the most convenient location for my needs and even walked me through how to use it.

What stood out most was their attention to detail and commitment to doing the job right. They left the work area spotless, and their friendly, respectful demeanor made the entire experience enjoyable.

If you’re looking for top-notch electrical work, I highly recommend Mario Castillo Electric. George and Edgar are a fantastic team, and I wouldn’t hesitate to hire them again!

Used them to install a couple of outlets. I was very impressed. The office was very professional, and got back to me quickly with an estimate. The scheduling team were very accommodating and found a slot that worked for me. Rudy did the job and was right on time, and very professional. He did a super job on the installation, include crawling under my house, and finding a junction point. He extracted dust as he cut the holes in the wall, so there was not mess to Clean. Exceeded my expectations and I will be definitely using them again in the future.

These guys are terrific! Mario came out to diagnose and give an estimate on Tuesday. He recommended we replace our panel and was able to schedule us for Friday. William and Rudy came out to do the work. They were on time and got right to work. They worked all day, were quiet and competent. Lastly, they did a great job repairing the wall and left the space clean. Highly recommend!

We had a great experience with Mario Castillo Electric. They were quick to respond and had reasonable prices. I loved how they were easy to get a hold of and answered all of my questions. Everyone was very professional, friendly and helpful.

Xavier C. and Edgar D. did a great job installing our new outlets! They kept everything clean and tidy too!

I would definitely use this company again!

Rudy and Edgar installed our EVSE charger in our condo. They did an excellent job and the work passed inspection on the first time. Giovani had also come out initially to do the estimate and be there for the inspector. This company is top notch. They were able to squeeze our DCC-9 load management box in the meter dog shed even though there was very little room to work with from other electric companies taking up the majority of the available space. Great quality work and a competitive price. I’d recommend them to anyone that needs electrical work done!

I have used Mario Castillo Electric several times for jobs ranging from addressing electrical problems to hanging pendants lights. Their team has consistently done good work that is reasonably priced. Xavier was out recently to install pendant lights for us and he did a great job. He was professional, efficient and the lights look very nice.

Luciano installed a new ceiling fan with a drop rod from our vaulted ceiling, and it works beautifully. Luciano made several visits--at no extra cost to me--before I finally got all the right parts together for the new fan. I'm very satisfied. Thanks, Luciano!

It was a pleasure working with Mario Castillo Electric. I got a service panel upgrade, new subpanel and EVSE hardwire install. I had done a bunch of pre-planning, so had a solid vision for almost every aspect of the project, from electrical loads on the house to preferred wire runs in attic and crawl space (to avoid plumbing and a bunch of exposed conduit), even had a preference on panel models. I wanted a company willing and able to marry the vision with their expertise. Mario's crew knocked it out of the park. From their salesperson to office personnel to the electricians crawling around under the house, they all communicated, respected the vision, showed me where it needed improving and completed the project a day early and looking better than I had envisioned. I didn't see a single shortcut they took, in fact a couple times, they went out of their way to better conceal wires when it would have been easier and quicker not to. I think quality workmanship is cosmetically pleasing and this crew really impressed me with both.

I don’t impress easily, Mario Castello and his team were awesome . From the initial call to Paola to the final city inspection they were remarkable. Everything went smoothly and on time as was discussed. A special shout out to Bryan and Aron, my technicians. They came on time, assessed the work to be done and went right to it. My new electrical circuit panel was installed before dark along with the re-stucco. For reasonable rates, professionalism and a personable group of people I highly recommend.

Great service & communication; efficient. We were able to get a quote for an EV charger installation over the phone with a photo of our electrical panel and short video of distance from panel to installation site. Efficient in getting quote and work done. Job took about 3 hours. Very satisfied with work done and efficiency in process of getting a quote. Definitely recommend for any further electrical needs.

Yesterday we had to replace our old original panel. From the get go Luciano who came out was the first person from Mario Castillo Electric he alone was wonderful when he came out to see what needed to be done, First perception of him and the company he worked for was definitely an asset got the call from my brother and it was a go. Salvador S. & Edgar O worked their tail off, both were very polite, explained things in detail and just two outstanding workers. They went above and beyond. The company alone had phenomenal reviews and now I see why. Overall a great company and I would highly recommend them. Thank you again for the wonderful service.

My name is Manuel. I found this electric repair company (Mario Castillo Electric Inc.) from Yelp information. I e-mailed them and got response quickly from them. It sounds like very good with estimates and other services. I decided to hire them. They already understand that I am deaf customer. We did get along well to communicate each other. We used with Video phone thru sign language interpreter. I am happy with the staff. Also the electrician installed new two junction boxes well before I switched from old fluorescent light fixtures to new LED light fixtures myself. It is perfect match connection before my former electrician installed old fixture that is very poor installment. I frustrated with it. Mario Castillo Electric Inc is honest and good price business. I recommend if you need to hire the electrician, get this company.

Vic and Dan worked in my apartment today as well as a few other team members, And they were all amazing. Respectful, very friendly and cleaned up any mess. I’m so happy that they came and worked in my house today.

Had a great experience with Edgar and Daniel from Castillo Electric when installing an additional outlet in my bathroom. They were on time, worked quickly, left the area clean, and did a quality job. Would definitely recommend!

I recently had the pleasure of hiring Salvador and Gabriel from Mario Castillo Electric Company for several electrical jobs at my home, and I couldn't be happier with the service they provided. They installed a new GFCI plug under my sink, an outdoor outlet, and a couple of Ring floodlight cameras. They also troubleshot an issue with my Ring Chime.
​Salvador and Gabriel were meticulous, clean, and focused throughout the entire job. They completed everything efficiently and professionally, and I was impressed with the quality of their work. I highly recommend Mario Castillo Electric Company for any electrical needs!

I would like to give a big thank you to Daniel Casas for replacing my circuit breaker. Compared to some of the other units being worked on in my apartment, Daniel was fast, efficient. He kept the area around him clear of debris and such by having something below him, making cleanup a piece of cake and he cleaned up the wall nicely after replacing the breaker. When he was finished, he gave a great description about the breaker and all the changes and differences between the old and new one and labeled all of the fuses for easier use.
