"We recently completed a major home remodel, including updating old wiring, adding new wiring for a 3,000 sf addition, and upgrading our panels. Mr. Kennison and his team were outstanding! He was incredibly informative, always responsive, respectful, and completely honest throughout the entire process. He took time to explain everything clearly and made a huge project feel manageable. The quality of work was flawless, and even inspectors commented on how well everything was done. His team showed up on time, worked efficiently, and treated our home with great care. Mr. Kennison holds himself to the highest standards, and it shows. If I could give more than five stars, I would! This company is the absolute best — trustworthy, skilled, and a pleasure to work with. I recommend them 100% for any electrical project, big or small. Thank you, Mr. Kennison, for such an amazing experience!"

"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."

"We had a complete rewire of the house, and we got a fair price. They completed the job, but missed several issues that the city inspector caught. They didn't replace some wires and tried to hide unfinished or incorrect work. For that I took away 2 stars. Ok but you have to watch their work."

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