I am guessing his bid did not include the electrical, that is why the homeowner obtained with the local franchise electro guy. Why I lowered my price, hmmm, not sure??, I dont think he benefited from it, I think he has done a ton of work for these people (really big house) I was just curious about my price? I had less than $60 in parts, 42 miles round trip, Iwas there a little less than 3.5 hours not including travel time.
