"Tony Plesh was very knowledgeable concerning generator installation. It was very comfortable talking to him. He answered all our questions clearly."

He went above and beyond and was nothing short of amazing. His company has handled other projects for us and is the only Electricians we trust with our home."

"We hired Ken of North Crest LLC to upgrade our electrical panel and install a new outlet. In the process, he discovered that we still had some dangerous old knob-and-tube wiring. So he checked and replaced multiple outlets, rewired a ceiling fan, and installed 2 replacement light fixtures. Thank you so much, Ken, for making our old house safer! We plan to hire Ken again to upgrade our kitchen and bathroom. Would gladly recommend him to anyone!"

"Neil showed up on time. Give me an estimate. Performance to work flawlessly. I was very happy with his professionalism. He took the time to instruct me on how to work my generator with the new transfer switch. Very highly recommended. He also installed an outlet on the outside of our house."

"This went fine.  I got their name from someone who used them for the same job.  They are personable and efficient.  I think they are also a family business.  In addition to the generator which I never really got to use, they recommend servicing yearly for about $150.  I did not want to be without power for many days as we were in the northeast several years ago.  I also did not want to handle a portable generator and the gas.  If I had any complaint at all, it was that it was difficult to reach them to do small jobs.  I would use them again and felt comfortable having them in my home.

"They did a perfect job! Would hire again!"
