What Philadelphia Is Saying
4.9 out of 5 stars · 200+ verified Google reviews
Lazo from Prime M&E installed our 20kW Generac after we lost power for 4 days during Hurricane Ida. Three weeks from quote to startup — permits included. During the next storm our power never flickered. Best home investment I've made.
I've used 3 different electricians in Wayne over the years. Prime M&E is in a different league. Upgraded our 150A panel to 200A, installed EV chargers in the garage, all in one day. Spotless, professional, and fairly priced.
Called Prime M&E at 11pm — burning smell from our panel. Lazo was at our Bryn Mawr house within 45 minutes. Found a failing breaker before it became a fire. I won't use anyone else for electrical work. Absolutely outstanding.
