"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."

Customers say: True professional

"Greenleaf Electric: very professional, assessed needs quickly. Installation of a ChargePoint home EV done after the local inspector required electrical upgrades for the main panel, changes to insure the house was up to code, including placement of a new mast. Other improvements done to bring my 1965 era home up to date. Greenleaf Electric is exceptional. Very pleased with the staff brought in to assist, the two inspectors from Frederick County, also Potomac Edison - all were professional. Also replaced security lights, installed Ring doorbell and cameras, installed new Carriage lights for the garage and front door. Just awesome! Thank you!"

"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."

"It was very easy to work with Joe to finalize a quote and get the job scheduled. Once onsite, Carlos and his colleague knew exactly what to do and how to run the new electric circuit across the house from the electrical panel to the garage. The installed the EV charger we had purchased separately exactly how we wanted it. Everything worked perfectly. They even went the extra mile to come back and patch the garage drywall where they had made a few holes to run the cable even though it was not included in the job initially. Overall very happy with both the price we paid and the quality of the work. Will hire again for any electrical work we'll need."

"Saul and Three Brothers services did a fantastic job upgrading our electrical panel. Saul explained everything throughout, agreed to do the work on a Saturday to accommodate our schedule, and was just generally very customer service oriented. We couldnâ t have asked for anything more. Highly recommend for electrical needs."

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