I have worked with Polyphase Electric for the past fifteen years. Polyphase has worked on many large UES renovations and the clients have always been impressed with their level of attention to detail and skill.

We recently enlisted the services of Polyphase Electric to help us facilitate all aspects of the electrical upgrades, changes, additions and installation for our 2015 Kips Bay Decorator Show House space. We were beyond impressed with the company. From start to completion they were unbelievably professional, timely & efficient. Every electrician we experienced personally was always pleasant & accommodating. Their ability to provide onsite solutions to site conditions and surprises was invaluable. We will definitely use them for our next project in New York.
