We recently had two lighted medicine cabinets installed in our bathroom by Low Current Systems and couldnt be happier with the experience. From the very first call they were friendly and responsive, scheduling the job quickly and they showed up exactly when they promised.Once on site, they worked cleanly and efficiently. They took the time to verify the wall structure and electrical wiring before proceeding, ensured everything was level and ran the wiring neatly inside the wall (no exposed cords or messy conduit). The lights on the cabinets were wired up cleanly and work flawlessly.Communication was excellent throughout: they explained what they were doing at each step, showed me the wiring and switches before closing things up, and double-checked that I was satisfied with the positioning and brightness. They even cleaned up their work area before leaving no debris or dust left behind.Overall professional, courteous, detail-oriented, and fair in price. I highly recommend them.

Denis got our landline back and running. Our line was completely damaged and there were crackling noises in the background. The line would completely go out as well. I contacted Denis and in 1 day he was able to come and repair the line. Once he fixed it, the phone sounded clear. He made sure to explain what was wrong and asked if we had any questions. He really cared to make sure we felt confident in everything. He was honest about pricing and he did the job in a perfect amount of time. I highly recommend his services!

We hired Denis because of another review about his honesty. We rolled the dice on this one since we were scared to always have someone be dishonest with us and try to make a quick buck. THIS WAS NOT DENIS! HE IS THE MOST HONEST GENUINE ELECTRICIAN EVER!!! We never did an electrical check on this house since we bought it 11 years ago. He did a full evaluation of our home and provided us a list of 25 things that could be done. He mapped out the fixes and changes. It took him 3 full days to get done. He even told us to remove a few things from our quote because they needed a simple cover that was bought online instead of charging us an extra $$$. SERIOUSLY THE BEST, MOST HUMBLE, MOST HONEST ELECTRICIAN EVER!!! THANK YOU DENIS!!!!!
