The electrician who came to my house was very helpful! He even offered to wait while I went to Menard's to pick up a medallion to put over the canopy for the light fixture. He was very considerate & helpful. He also fixed the loose wires on my overhead garage door, so that when I close the door it stays closed. He also gave me a quote for a future project that I have. I look forward to working with your company again! Thank you for the great service!
