"Joe's Electric returned my care within minutes of me contacting them. I had a technician in my home in 1.5 hrs. Who quickly identified and fixed the problem within 35-45 minutes. They saved me from losing a whole day of work and it was worth the cost vs loss I would have incurred."

"Perfect and smooth journey, Jorge came pre instillation to check the electrical panel and where the the charger was going to be installed and after the review he text me the cost of parts and installation, after I received the charger he came on time and the job was completed. I was updated by text messages throughout the process. In the future if I need any electrical work I definitely use JK Flores Enterprise."

"Wilson Electric was great to work with, they promptly responded for my request for a quote and provided me an estimated price for the job as described. The day they arrived to do the work, they finished in about 2 hours and made sure we were happy with the job. I would use them again in the future."
