When you call GLEC, you get a master electrician providing you the highest quality work at a fraction of the cost. You are losing out big time when calling a large electrical company! They will send an unqualified employee, and you will pay the overhead for them to learn on your property. We at Green Light Electrical Contractors strive to maintain our reputation as a high quality, very service oriented company with our main focus being customer satisfaction.

"Ryan was on time and a great worker, couldn't recommend him and his company enough!"

"I recently hired Hewitt Electrical for a full electrical wiring and panel upgrade at my property, and I?m extremely satisfied with the results. From the initial consultation to the final inspection, their team demonstrated professionalism, expertise, and a strong attention to detail. They began by assessing my outdated electrical panel and explaining why an upgrade was necessary to meet current safety standards. The quote they provided was clear, fair, and competitive. Scheduling was smooth, and they consistently arrived on time and ready to work. The team replaced the old panel with a modern 200-amp system, updated key circuits, and ensured everything was properly grounded and clearly labeled. They worked efficiently, kept the site tidy, and minimized disruption throughout the process. What impressed me most was their commitment to safety and code compliance. They communicated every step, answered all my questions, and made sure the work passed final inspection without any issues"

FAQs for electrical for home addition or remodel installation projects in Oxon Hill, 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.
