"My technician Brian was fantastic! He was very knowledgeable and shared that knowledge in a very easy to understand manner. He offered me suggestions for my concerns without trying to offer me products or services that were not needed. We had them upgrade our electrical panel to allow our generator to power our home. Brian not only showed us the process, he helped me to put my generator together and get started. A true professional and we will be calling him back out to install our EV Charger when the time comes. Highly recommend!!"

"First time residential customer here. I had a fantastic experience with Mr. Electric of Houston Midtown, specifically with electricians Franklin and Zack. Franklin was very professional, polite and knowledgeable, he evaluated my situation, advising me of my options and a competitive quote. We agreed and he got right to work with Zack the following Monday. Franklin and Zack were both very polite, professional, meticulous and clearly they take pride in their work. Since there were several new light fixtures being installed, they both communicated clearly and timely to make sure that the fixtures, switches get installed in the preferred locations. Wiring and overall fixtures alignment was perfect. Breaker box is also now up to code with surge protector and grounding wire which was missing. The job was done with such care and expertise that the benefits truly outweigh the cost. It's a worthwhile investment for the betterment and safety of my home. I highly recommend their services! I will definitely use them as my electric company from now on."

"Outstanding service. We had a breaker box replaced, including all the rewiring associated and a new ground. Also had electrical fixed that goes to the dryer. They made an appointment for the next working day, were on time, and did an excellent job. Everything was carefully explained to us. Nice people and very professional. We would hire again."

"I had an electrical outlet installed on my brick fireplace so I could hang my TV up. I was quoted from another company $600 and would have the outlet box exposed from the brick. I used Enoch and it done for $150. Plug looks great! I'll use Enoch anytime I need electric work done."

"Oscar and his crew just got finished re-wiring our entire house, and they did a fantastic job. Their work passed inspection without a hitch, and we couldn t be happier. The entire crew was professional, working together as a team, and were also friendly and extremely polite. They showed up every morning when they said they would, worked hard all day long, and cleaned up after themselves every afternoon before they left. And they went out of their way to make it easy on us, setting up area lights with extension cords so we were never completely without electricity. We ll definitely call Right Pro if we ever need more electrical help!"

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