"I couldn't have asked for a better experience. They were hired to replace the main electrical panel/breakers at my elderly mother's home. Roni, the electrician, was a wonderful communicator, and was very knowledgeable and thorough in completing the job and in putting her at ease. The price was very reasonable. I will be using Nasr Electric in my own home, as well as recommending them to all my friends and family in the DMV area."

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!"

"Green’s Electric was great! They quickly provided an accurate estimate for the work we needed done. We appreciate the attention to details on the professional appearance of the work as well as the reasonable pricing. The finished work looks better than we could have imagined. Green’s was able to schedule the work very quickly and was on time and finished within the original estimated timeframe. I’d recommend this company for quality, reasonably priced master certified electrical work. They were great!"

FAQs for electrical for home addition or remodel installation projects in Rockville, MD

Because installing coax outlets involves working around existing electrical wiring and confirming proper grounding, many homeowners prefer to hire a licensed electrician. A professional completes the work safely, secures the line behind the wall, and ensures the installation meets local code, which reduces the risk of damage or future repairs.

You still need a coaxial outlet for most cable-based internet services. The modem draws its signal from a cable line that terminates at a dedicated wall jack. Once the modem is online, your Wi-Fi router can broadcast the signal throughout the home, so the outlet’s location doesn’t affect wireless performance. If an existing jack is damaged or in an inconvenient spot, an electrician can move it or install a new one to maintain a strong, reliable connection.

Coaxial cable loses signal strength the farther it runs. A 50-foot length introduces noticeable loss, and a 100-foot stretch can drop the signal by roughly 30%. A weaker signal can result in a fuzzy picture or slower internet speeds. To maintain high performance, limit cable length whenever possible, select the correct cable grade, and route it efficiently. If your layout demands an exceptionally long run, an electrician can install an inline amplifier to boost the signal and maintain picture or data quality.
