"Had an electrician out to give me an estimate on replacing my electrical panel. Decided against replacing it because that wouldn't have solved my issue. My house was built in the 60's so it needs all new wiring. I just had him show me which outlets were on each of the channels so that I could spread out my devices that needed a lot of power, specifically my space heaters."

"We had the privilege to work with Raymond for our panel upgrade / conversion and his team did a phenomenal job. The project was completed in a timely manner and he was able to address any issues that came up with the city. The pricing was very fair and he explained everything in detail while giving updates throughout the entire project. I would highly recommend working with excellence electric and the team for any electrical issues! Thank you again."

"Austin Van Sant knows his business. We had him take our solar panels off our roof as we had to have our roof repaired. Once that job was completed, Austin reinstalled our solar panels using a better footing installation that attaches to the rafters, thereby not having to cut any tiles (as the previous company Horizen Solar did, which caused roof leaks). He also applied a bird mesh to the bottom of the solar panels to prohibit birds from making nests. He is extremely knowledgeable, reliable, and conscientious. I highly recommend Austin Van Sant and his partner Louie. They work fast, are light footed, and are very congenial. We are very pleased with their performance."

"I was extremely satisfied with Verengo Solar. It has cut my electrical bill way, way, way down. I've worked with a lot of contractors and they were extremely professional. They put in a lot of panels and they're not on the roof, so they had all sorts of installation problems. They had to run the lines up a hill, through my backyard into the electrical panel on the house. It was a tough installation. My out of pocket electrical expenses has gone from $2,500 a month before I got the panels installed and $900 a month."

"The overall experience was good. Even though our roof is quirky and we have parts that are shaded, they were able to angle panels in different areas to get the maximum sun exposure. There was one glitch...the system wasn't working when we first turned it on upon approval from the electric company but once I contacted them they were quick to come out. The problem was a switch that hadn't pushed on properly and was an easy fix. We felt like they worked very hard to get the system in for us quickly and were polite and professional throughout the experience."

"Landmark construction and energy crew executed a whole kitchen renovation for us, including custom cabinets, new floors, new countertops, electrical (sub panel with lights and switches), recessed lighting covering, plumbing fixtures, took down wall to expand the kitchen area by merging it to the living room space. The cost included all the materials for cabinets and countertops, backsplash tiles, new floors and the appliances. We are thrilled with our new kitchen! Charlie, Nir and the workers did an excellent work and while the whole job was completed in less than a month. You could see how hard they worked in order to keep the work moving so it will be done in that time period that they originally promised us. On top of that, they worked hard to get things to our requirements (i.e. to stain the cabinets, complete the paint etc…). We all were pleasant and satisfied to have them work at our house and mainly with Charlie (project manager) that was approachable and supportive when we had requests or problems. I must mention that on few times, we were bothered with some of the workers when they didn’t show up when they should, or worked more hours on the electricity panel. Clearly enough, it’s normal that you must have to handle a lot of problems when you decide on going for this type of project. The final cost was the same as we agreed with them at first, although we were sure that it will be increased due to some additional things that we did during the work and that were not included in the first estimate/agreement. Overall, we would give LANDMARK CONSTRUCTION AND ENERGY CREW Construction a strong recommendation!"

"I was contacted within one hour of my service request and an appointment was set for 8:00 AM the next day. They arrived on time gave me an extremely reasonable estimate and proceeded to do the repairs and installations I needed done. The service man worked quickly and efficently, checking to make sure things were where I wanted them to be and cleaned up his work areas when he was finished. I have several other projects and will definitely use Western Electrical & Lighting Services again and recommend them to others."

"Everything worked out great.  He mostly did high, very hard windows like skylights and very high windows.  He did a thorough job of cleaning the screens and windows.  I will call him for help in the future.

FAQs for electrical wiring or panel upgrade projects in Cima, 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.
