Berk's Electrical and Lighting's employees were always courteous, clean, sure to come on time, and very good at explaining what I needed to do and why I needed it done. They knew their stuff. They helped me make decisions on things, telling me what would be best and what was the most economical way to do things. I needed a lot of rewiring and line dedication done. I also had a lot of hot wires that weren't even grounded. They really did do a lot for me!
