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!"
