I have a wartime house that i will be rewiring and was wondering how you guys would go about pricing the job.Its your basic lath and plaster construction the service is new and the basement already wired.The first and second floor is knob & tube.I work mostly Industrial but have done a few of these jobs, however it was for family and I worked for free.Should I charge T&M or by the drop?And how much per drop if I do it that way.Happy New Year
