I will do what the customer requests,..after all, I'm setting the price,..so it doesn't matter to me.
That said, I have seen times when someone asks to do "Just this much",..But,..they end up going with the rest. Sometimes I think they're maybe feeling you out.
*Realtors and their customers are some that will routinely get partial work done,..the curb appeal part.
First job I did for Remax was one of their agents,..I didn't know,..I did one side of the roof,..since then I've done numerous jobs for Remax and their customers. If I would've turned it down I would have lost ALOT of work.
Yea, don't turn work away,..simply because it's income and it keeps things moving. Secondly, that customer may lead to other work.
