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!"
