"Working with Joel from start to finish was great! Very up front about the process, costs, and ensured he delivered on what I wanted and needed. Joel was extremely punctual with great communication which made my generator installation go very smooth. Pricing was extremely fair and I plan on using Smith electrical in the future for other projects. I would highly recommend Joel and his team!"
