"This job was done quickly and correctly. I used him in the past with running stove upgraded wire to the electrical box. I was very happy with that project, so I used Vital Electric again and will use him in the future! Pricing is very reasonable."

"I hired greenleaf electrical for my ev charger / electrical panel upgrade project. Gill was very friendly and willing to answer any and all questions I had. He told me the work would take about two days to complete the project and what was about right. Additionally, he was accomodating to a last minute change I requested for the location of the EV charger plug."

"It was very easy to work with Joe to finalize a quote and get the job scheduled. Once onsite, Carlos and his colleague knew exactly what to do and how to run the new electric circuit across the house from the electrical panel to the garage. The installed the EV charger we had purchased separately exactly how we wanted it. Everything worked perfectly. They even went the extra mile to come back and patch the garage drywall where they had made a few holes to run the cable even though it was not included in the job initially. Overall very happy with both the price we paid and the quality of the work. Will hire again for any electrical work we'll need."

"How did it go? Not well. I finally just bought the required ladder at 200 USD and did not pursue Kolb Electric further. I should have just bought the ladder in the first place. Live and learn."
