Checked and repaired passage lights that were not working and installed four dimmer switches David, the technician called when he was 15 minutes out and arrived punctually. The work was carried out very efficiently and professionally. He explained what he was doing and gave me a few hints to save on power usage as well. Great organization and I will be using them again 

Business response:

Thanks for the great review. We look forward to your next project !

Rewired six switches that operated four ceiling light fixtures on two different levels of the house and one ceiling fan. A prior electrician had reconfigured the switches that controlled four light fixtures on two levels, when he installed a ceiling fan in the hallway upstairs. Unfortunately, the new configuration required walking through the hallway, in the dark, to get to the single switch that turned on the ceiling light fixtures while the fan could be turned on and off using the wall switches at both ends of the hallway ... read more

Business response:

Thanks for the great review. This was a complicated project due to a previous "electrician" attempting to rewire multiple switches and lighting fixtures. He made a real mess of the wiring, but our techs figured it out and provided the exact solution that was requested. We look forward to your next project !

I purchased a deal through Angie's List to have a ceiling fan put in a new location. After purchasing the deal, I informed the company that I also wanted lighting put up in a location that already had lighting. The company informed me that this would be okay at an additional cost. The contractor arrived on time and completed the first job. He did an excellent job and made sure the room was cleaned after he finished. He then did the second job. Again, he did an excellent job and ensured that the area was cleaned when he finis... read more

We had two light fixtures in the upstairs hallway that needed to be replaced. The technician, Todd, was punctual and personable. Knew exactly what to do and how o do it and made short work of the job. My father always emphasized the importance of cleaning up your tools and the job site when finished with your work, and I was very impressed when Todd did just that as part of his normal routine. It says a lot about the pride he takes in his work. I'll definitely request that he return for all future projects. Well done! 

Business response:

Thanks for the great review. All of our techs are highly-experienced and take great pride in their work. They also have excellent communication skills which is a key component to any successful project.

We had three smoke alarms replaced with combination smoke/carbon monoxide alarms. The technician was on time and courteous. He replaced the alarms and explained the instructions for the alarms. 

Business response:

Thanks for the great review and allowing us to make your home safer by installing Combination Smoke & Carbon Monoxide Detectors. Not only are they required by law in MD, but they are inexpensive and effective life-safety devices. They also need to be replaced every 8-10 years.

Replaced bathroom light switch; confirmed it was just switch and not a bigger issue such as a short. Also helped disable wired doorbell. Very well. Provider told me how to check/resolve this issue myself next time and only spend $.69 and not $100. Also made great recommendation about which wireless doorbell to use. I had basically disabled old system myself but he confirmed I had and also helped me find transformer box so we could confirm total disablization. 

Business response:

Thanks for the great review. Our entire staff is committed to superior customer service and we will do whatever we can to save our clients money whenever possible.

I needed to replace a GFI Outlet / Switch in my bathroom. My initial appointment was between 10-2 pm. By 1 pm, I had not heard from the technician, so I gave them a call. Turns out he was held up at his previous job, but they were able to get to me later in the afternoon. Technician was very kind. He was prompt and did the job within about 20 minutes. 

Business response:

Thanks for the great review. We appreciate when our clients take time to provide valuable feedback on AL which helps others in the community make informed decisions
