Hired 3 Guys Electric and Insulation to install a 240V EV charging outlet in my garage and replace my electrical box. Pricing was fair and quoted upfront with no surprises. The work was clean and very professional. The new panel looks great and everything’s up to code. Easy to communicate with, and they did exactly what they said they would. Would hire again and recommend!

Details: Replacement • Circuit breaker panel with switches • Outdoors • No, I would like the pro to buy the circuit breaker or fuse box • House

3 Guys Electrical & Installation did an excellent job installing my EV charger at home. Very professional, neat, and detail-oriented work. He also handled and secured the city permit, which made the entire process stress-free. Highly recommend him for EV charger installations and electrical work.
