"Top rate Company, they replaced my electrcal panel and did my pool bonding in Sept 2024. Ryan the Electrician was very professional, prompt and explained everything in detail.

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!"

At PowerWorks in the DMV area, we are proud to offer a wide variety of services to suit your needs. Each service will be performed by and or under the supervision of our Master Electrician, so you know your project is in good hands. We are committed to excellence in every aspect of our business. We uphold a standard of integrity bound by fairness, honesty, and personal responsibility. No projects are too small or too big, we are here to help all new and returning clients.

"So I asked 8 electricians for a quote on installing a Chargepoint charger. The wiring itself was already done, had its own dedicated breaker, and everything. All that was needed was to take off the Nema plug and use its wires to hardwire it. It was a 20 minute job, and I knew it. However, 6 of the people I asked quotes for just either ignored the information I sent them or assumed I didn't know what needed to be done and tried to basically ask for $2000 an hour for labor. Electricians deserve to be paid well, but it was ridiculous, knowing I was being scammed for a job I could probably do on my own (albeit it'd probably take me three times longer), but for insurance reasons needed someone licensed. Powerworks came the day I hired them, had a reasonable price, and installed it in 20 minutes. Fast, efficient, and friendly. Most importantly, they actually listened to what I said I needed and didn't write me off like I was another customer who doesn't know how things work or what I need."

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..."

"Don’t use the plumbing! Called to have Kohler toilet tank plunger repaired. Whole installation is $20. Labor is an hour at $80 so the price is $150, at most. No, they charged $450–BS! These guys are a scam. No prices and I told them to have the repair person call me before arriving. No call, no prices. And, then the repair person has the stones to tell me that everyone overcharges!! Let’s start with not using Beacon!!!"
