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..."

For 50 years and two generations, Clinton Electric Company, Inc., has been the premier electrical contractor in Maryland. Since 1969, we have taken great pride in providing excellent electrical service to over 50,000 loyal customers in the Greater Baltimore area. With over 80% of our business coming from repeat customers and referrals, we take that as a great vote of confidence in Clinton Electric!

"The technician was friendly and courteous. I understood that they needed to charge an inspection fee , but what seemed excessive and unfair was the categorization of diagnostic levels that raised the cost of the service call beyond what I considered a reasonable expense for the type of repair needed. For this reason, I cannot recommend this company. It would have been better to work with a company that charges an hourly rate. I will never use this company again- the fees they charge for the service rendered despite their politeness and friendliness are simply too costly. The determination that a pump servicing a fountain needed to be replaced cost me $500 plus their inspection fee. Outrageous!"

"I needed an outdoor outlet and receptacle placed on the opposite side of my yard, from the house, to run my pool and pool heater. Wolf Electric came out and added 2 GFCI breakers to my box, ran the wiring, drilled through the foundation, ran the conduit, put in a pole, receptacle and disconnect for me. Alex and Mike were helpful, professional, pleasant, knowledgeable, accommodating and timely. Even when I didn’t give them the right info upfront, due to my confusion on the new heater, they were quickly able figure out what I had and pivot to give me what I wanted and what I needed to have everything up to code. Great experience and I will definitely reach out for my next project. I highly recommend! "

"Do not use this company. They will rip you off. The contract was for eight 300W LED 40 ft pole lights, but I caught them redhanded installing 240W. Who does that? Then, they broke my lock and broke into my sprinkler room which I saw on my video which they admitted. Then, Kolb sued me for not paying the bill which I disputed due to lost tools as result of the break-in. Who does that breaking into a customer's sprinkler room and not informing that they did. I had to catch them on my video. Not only that it took over one year to the work proposed work. TOTAL FRAUD. I will be going to court...."

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