"I found Wire works through Angies list. And I am so glad I did, I am picky on who I hire and I was very happy from the first phone. My mother had a can light that was malfunctioning. The Electrician that came out was very quick to find the problem and recommend how to solve the issue. Once I had the new light and gave them a call, they came right out within a couple days and installed the new light. I would absolutly hire them again."

"Very respectful, on time, and did the work professionally. Will definitely keep their card on the fridge :) We installed an external receptacle for our portable generator and a mechanical interlock for safety to prevent back feeding to the grid"

"The professionalism of Josh, the project manager and all of the workers was top notch: they were competent, experienced and explained each phase of the electrical project. We now have a new load center installed, as well as a generator interlock system. All of the work was completed in one day, as promised. Josh made sure that my husband and I were fully informed about how to connect our new generator."
