What Our Customers Say
Straight Answers. Clean Work.
“Marcus came out within an hour when our panel started buzzing. Diagnosed a loose neutral, fixed it for half what the last guy quoted me. Honest people.”
“Installed our EV charger and walked us through everything. Pulled the permit, came back for inspection day. Old-school service.”
“We bought a 1920s rowhome with knob-and-tube. Keystone did the rewire over two weeks, kept the dust contained, didn't trash our ceilings. Worth every penny.”
