"Mike and his team did an exceptional job. The work itself was an overhaul of an outdated General Pacific Panel and relocation of an out of code closet panel to the outside, mast/riser, etc. This also requires arc faults, GFIs, ground rods, etc. They explained each step, walked me through the ins and outs of where the wiring was going, where the ground rods were getting placed, what types of breakers were needed for code, and came in below budget. Hard to find folks that shoot you straight, take care of all the additional questions you have, and allow you to make small changes to statement of work all under budget (I.e. installed an additional outlet and hardwired a ring doorbell through masonry). Would recommend you check them out, especially if you need an old General Pacific panel replaced or 50s/60s electrical brought up to code."

"They showed up on a Tuesday, let me know what the problem was, fixed the problem that I had, and told me about future upgrades that I could wait on for now. They did this all in about an hour. They did a good job and had reasonable prices."

"Awesome company! Mike came to my home and gave me a very thorough quote for the work I needed, he was very personable and honest. He was able to schedule my panel upgrade for the next day. Quentin(sp) installed my panel, was very efficient and kind! Also installed two lights in my home, did all of this in about 4 hours! Definitely recommend and will use for future electrical work."

"The panel replacement went way smoother than I expected, especially since they had to move it from a closet to exterior wall. We just bought the house, and it's a bit old, so it had a lot of malfunctioning light fixtures and old wiring. W3 took care of everything! I was very impressed with how thorough they were, in their work and in explaining everything to me. I also appreciated how professional they were; not in a stuffy way- just showing up on time and cleaning up and such. Seems like the really enjoy their work and take pride in it. I highly recomend W3 Electric!"

"I had my whole house rewired. The job was done right and efficiently, and customer service was always great. I had no problem getting in touch with the company with any questions. The workers were wonderful; always helpful and didn’t mind me asking any questions. I heard no complaints; the weather was hot, but they got the job done in the estimated timeframe. I commend them."

"The tech, Bradley Cooper, who came to my house was just awesome, courteous, and patient. First he came out to do an estimate and presented an affordable solution that others had not considered such as going thru my attic to run the line to the back yard. There was a slight snafu once I decided to go with Baker Brothers for the electrical work. The person who took the order didn't catch I wanted them to come to install the new breaker circuit and didn't properly schedule enough time to do the work as it was an all day job. No worries, Bradley took care of the mix up and was back the next day to do the work. Despite us being indecisive on where we wanted things put and our lack of knowledge about what was needed to hook up the swim spa, Bradley patiently waited for us to make a decision and even called the place that sold us the swim spa to get help on where to place the wires for the swim spa. Once the work was done, Bradley and his assistant cleaned up after themselves. The assistant, a former AC man, even told us that it looked like our air conditioner overflow was full and we needed to get that looked at. Overall, it was a great experience working with Bradley & Baker Brothers. Will definitely use them again."

FAQs for electrical wiring or panel upgrade projects in Sunnyvale, TX

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.
