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!"

We specialize in electrical services, repairs, installs, lighting, panel upgrades, ceiling fans, and more! We guarantee your satisfaction, and we won’t leave until the job is done right. We pride ourselves on the quality work we provide, while delivering great customer service! Check out all the services we offer below and call -or- click to schedule an estimate today!

"They did an excellent job of installing the new panel at a reasonable price. Also they had financing options that were same as cash. I was provided some options of circuit breakers and the price with the options. The differences in breaker were explained and the code requirements for my area was also explained and compared to other local code standards. I was able to customize the options a little bit based on my needs and I have more space in the panel if I have additional requirements. Going from a box from the 1960’s to a modern solution mad a lot of sense. The installation was smooth with only a short time without power. Throughout the process, I was well informed of the progress. My family was able to work remotely from home during most of the install without too much disruption. (Used cell phone for internet and laptops while power was off.) They even installed a monitoring system for me to track the electrical use of the house. Overall they did a great job and I am very satisfied."

"Upon inspection of electric panel Ryan found signs of damage, indicating need for repair or replacement. Since the panel is more than 15 years old, I opted for replacement. The surge protector will be included with the new panel, along with a year-long service maintenance plan - to be installed next week."

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