Seems like in my area, if you don't do the job by the square foot, you don't get the job, then you gotta do it around $ 1.85/ sq. ft. then you MIGHT get the job. Don't seem to be an option if you want work where I live. I've done houses at $ 1.85 sq. ft., not hardly taking time to eat, shopping for the best deals on material, and still not hardly making a profit. Made maybe medium wages, but that's about all. And at least one of the building contractors I've done work for, won't let you include the garage in the square footage. I agree that sometimes and most of the time, the garage has more in it than a typical bedroom. Your electrical panel, garage door openers, most of the time my experience has been uneven dirt to work on because the garage has not been leveled yet for the concrete when I get in there, so I have to try to work off of a ten foot ladder on uneven dirt and try to run my homeruns, etc. Don't seem fair somehow, but seems that's the only way to get their work. I'd rather do old work and service changes most of the time. I don't really know how the contractors in my area make much money, unless they pay their help under $ 10/hr.
on some of the new houses. I guess I'm missing something somewhere. Anyway, my input
Hope it helps.. Steve
