"Project was upgrading service from 100 to 200 amps, installing new panel, new meter, grounding, and a new drop from the street. I gathered a number of quotes, and by far felt the most comfortable with Mr. Hyman. Plus the price for the job was in line with my expectations. The work was completed quickly and professionally. I'd definitely recommended using them."

"I hired greenleaf electrical for my ev charger / electrical panel upgrade project. Gill was very friendly and willing to answer any and all questions I had. He told me the work would take about two days to complete the project and what was about right. Additionally, he was accomodating to a last minute change I requested for the location of the EV charger plug."

"not just professional efficient! Unbelievably fair priced literally less than half of what a major competitor on this site quoted using my own parts and my own wire! Just because there are any energy list doesn’t mean some people won’t try and rip you off and fools will pay it. Mr. NAGY is a professional and very ethical. I’d recommend hiring him again and again!"

"Dominic was great. He arrived right on time and started tracing a hard-to-find short. For over four hours he checked socket after socket, switch after switch, ultimately crawling through spaces I didn't know existed. He found the problem, a rodent-chewed wire that was a likely fire hazard. He corrected the problem with new junction boxes and updated the outdoor sockets. He demonstrated a level of knowledge, professionalism and determination that puts him at the top of my list of go-to electricians. I'll be asking him back soon to take care of some outdoor lights that need upgrading. I hope he won't be bored!"

"Ludwing did an amazing job! He installed a new light fixture in my home and what I appreciated the most was that he explained the connection to the wiring and how things work. This was very helpful because he corrected a job from a handyman who installed a light fixture that could have destroyed my home. He is a master of his craft. Not only will I use him for future projects but have also shared his contact with friends needing electronic assistance."

"Felix came to my home to install 3 low profile electrical outlets underneath my dry bar cabinets this morning. I have under cabinet outlets under my kitchen cabinets, so I wanted them in the dry bar area also. Felix was punctual and professional. He did a great job in installing my stainless steel outlets. Felix did some upgrades to my other electrical outlets in my basement area also. I had taken estimates from other electricians, but Three Brothers Services, LLC offered the most affordable prices for my project. I would definitely recommend this electrical service to friends and family."

"On June 10, I had a company to install security equipment in my home. In doing so, the installer drilled through a wire and I did not have electricity in several outlets due to the damage. Since the company did not have an electrician on staff and was unable to refer me to anyone, I turned to Angie’s List for help in finding someone to correct the problem. I called Hands on Electric on June 11 and spoke to the owner, Kevin Williams. I explained my problem to Mr. Williams and he gave me a window of time in which he would be able to come out. Not only was he able to come out the same day that I called, but Mr. Williams was able to come much earlier than expected. Once he arrived he was able to trouble shoot and diagnose the problem. Mr. Williams was very, very friendly, professional and honest. He was able to answer my husband’s questions and explained what he was doing as he made the repairs. My husband was very happy about that and we were both impressed by the years of experience Mr. Williams had for his age. I have been looking for an electrician for a while now and have decided that I will be using Hands on Electric for all of my future projects. I was very pleased with the work that was done by Mr. Williams and will recommend him to my friends and family when they need of electrical services."

FAQs for electrical wiring or panel upgrade projects in Bethesda, MD

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.
