Who thinks that contractors raise the price on the system? I would like to know what the labor is costing me.
I usually don't install equipment bought through somewhere else, but the very few times I have, I bid the complete job, then subtract for the wholesale cost of my equipment and add X amount of dollars for dealing with a brand that I'm less familiar with. Got to make atleast the same profit for the same amount of work. The H/O usually spends more, not to mention warranty issues.
