"The whole process, from estimate to follow-up service, was superb. There was an issue with the installed timer. A simple request and the replacement was scheduled for replacement within a week at no charge. A request for an upgrade was also done quickly for a small charge. I highly recommend Martin!"

"Excellent! Haik and his crew had the unfortunate task of correcting an illegal job done by another electrician. Haik and his crew immediately came to work on our condo. They were courteous, punctual, and very professional. The work was inspected, as required by law, with no citations. As a last minute request, they also upgraded 3 of our outlets and replaced a light switch without changing the amount to our original contract. Their quote was competitive and I felt good working with an honest company. What Haik said they would do was promptly, efficiently, and correctly accomplished. A definite gold star and will not hesitate in calling him if any electrical work needs to be done."

"MJ services was a professional and reliable business. They upgraded my electrical panel to 200. He obtained permits from the city and everything easily passed during inspection. His prices were reasonable and he even installed my EV Tesla charger. Would recommend him to anyone."

"I got a few estimates to get more power out to my studio. Everyone quoted me about 4K to upgrade my panel and get dedicated line out to my studion. These guys were to only ones that looked for a better/more economical solution. I sent a pic of my panel and he remembered that I upgraded my kitchen a while back but noticed that my electric stove had it's own dedicated line. He asked me, did you convert to gas when you remodeled? I said yes and he said, great, we take the line that was dedicated to the stove and we use that. It saved me $1500 and it worked perfectly. I would absolutely hire again!"

"Alset Electric Company is ran by Eddie. Eddie is very professional, efficient and very detailed. In the month of June (2026), I had Eddie to install the RING..I chose the wire RING system with the cameras...Eddie and his crew was very efficient and cleaned the mess afterwards. I had Eddie to I install my address numbers thats lights up at night on my new stone wall for the house. Eddie did an excellent job. My neighbors are still paying me compliments. Here we are in July (2026), my dad asked Eddie to install new water sprinklers for the front yard and backyard. Eddie explained detailed what he done. Eddie is very affordable. If you want very good electrical work, Eddie is the one to call. I have used his services many times now and very satisfied. If you later have questions for any service he had done he will gladly talk to you and stop by if you ask him to."

"I needed to upgrade the electrical panel in my home and I didn't know who to trust. I did lots of research and found Accurate, and I am glad I did! They made the process super easy and put my mind at ease. In fact, I even had them install a Whole Home Fan at the same time. They sent me text messages when the tech was on his way with his photo and bio, so I knew who was coming to my home. Kenny was the lead with Q and Gabe helping. They were very patient and informative, answering my hundreds of questions. They kept me in the loop with all their findings and did a great job on both installs. Even the process of applying for financing was super easy! I am so happy with Accurate and plan on using them for all my home issues in the future!"

FAQs for electrical wiring or panel upgrade projects in Glendora, CA

Yes, a licensed electrician is essential for this project. Running an electrical service from the road to your house involves connecting to utility power lines, complying with national and local electrical codes, and safely handling high-voltage systems. 

Licensed professionals understand proper wire sizing, grounding requirements, and voltage drop calculations needed for safe installation. Most jurisdictions require permits and inspections that only certified professionals can obtain. The safety risks and potential for property damage make this project inappropriate for DIY attempts.

Overhead installations are less expensive than underground options. For a 1000-foot run, overhead service costs between $8,000 and $15,000, while underground service ranges from $10,000 to $25,000. 

Overhead lines require less labor and fewer materials since they don't need trenching or conduit. However, underground lines offer better protection from weather events and aesthetic benefits. Your decision should balance your budget constraints with long-term reliability and visual preferences.

You might need to upgrade your electrical panel depending on your power requirements. If your existing panel cannot handle the additional load from the extended service, upgrading to a 200-amp service (costing $750 to $2,000) may be necessary. 

A licensed electrician can evaluate your current system and determine if an upgrade is required. Factors include what you'll be powering at the end of the line, existing electrical demand, and whether voltage drop over the distance will affect performance.

Running electric service from the road to a house requires electrical permits from your local building department, costing between $500 and $2,000 depending on your location. You may also need excavation permits for trenching work if installing an underground service. Your utility company will have its own application process for connecting to its grid. A licensed electrical contractor can handle all the necessary permit applications as part of their service, ensuring your installation meets all local code requirements.
