"Kenneth and Juwan from AMEW electrical did a fantastic job installing a NEMA 14-50 Wall Connector for my Tesla. They were quick to respond, had great communication prior to the visit, were early and had one of the better prices for the project involved. Along with being one of the top rated on the Tesla website for electricians in the area. During the visit, Kenneth explained to me what was going on, even when I was quiet, he would ask me if I had any questions what he was doing. Even curious electrical questions I had like how do you know where to move around as to not get electrocuted or if you're drilling a hole, making sure you know not do hit a wire. He was great in answering any question I had. Both were super personable during my interactions with them. I was able to charge the Tesla immediately after they completed the work. They even cleaned up all the dust and debris from the installation. 5 out of 5 will definitely hire them again and use them for any electrical work I need to do around the house. I can't recommend them enough."

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 responded to the request immediately, had great availability and showed up promptly. I had a strange issue where I had 2 circuits crossed that was causing issues with my HVAC unit and lighting (likely caused from my own DIY efforts). He offered a fair rate and was able to quickly troubleshoot and resolve the issue. I would recommend them for any small or large projects because of his transparency, skill level and professionalism. Green Light will go into my "Rolodex" for any future electrical issues..."

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

Electrical wiring can last between 50 and 70 years if properly installed and maintained. However, factors like moisture damage and overloading outlets can shorten this lifespan. To extend your wiring's life, unplug electronics when not in use, avoid overloading outlets, and schedule regular electrical inspections every five to ten years.

If your house was built in the 1960s and hasn't been rewired, it likely needs it. Older homes may have outdated wiring like knob-and-tube, which poses fire risks due to flammable insulation. Rewiring ensures safety and may also require updating your circuit panel, outlets, switches, and fixtures. Contact a local electrician to help with your rewiring needs.

Yes, rewiring your house is worth it, especially if your wiring is outdated. It improves safety by reducing fire risks and can increase your property's value. However, you may not need a full rewire. A home inspector can tell you if a partial rewire will bring your home up to code.

Yes, you can sometimes rewire a house without removing walls. Electricians might access wiring through attics, basements, or crawl spaces, or make small holes to run new wires. However, this isn't always possible, and in some cases, removing sections of walls is necessary to ensure the wiring is installed safely and meets code.

A house should typically be rewired every 25 years to maintain safety. Over time, wiring deteriorates, increasing fire risks. Regular electrical inspections every five to ten years help assess the need for rewiring. Staying proactive with maintenance ensures a safe, efficient electrical system and prevents potential hazards before they become serious issues.
