My house was damaged by a fire which destroyed wires and more. The guys from Swiftec were absolutely amazing!! The set me up with temp equipment and new wiring until my house can be repaired and got power restored to my house within a couple days!

Absolutely wonderful. Tech came out the same day and did much more than originally planned. He was kind, courteous and respectful. He put on shoe covers so not to track mud all over the house, explained what needed to be done and the charge for the repair clearly. We had lost all power to the back of the house and within an hour he had it fixed and even changed out several plugin while he was there. I am so very grateful!! Thank You!!Posted on Google
