How do I go about charging a customer for a project like building a deck or hanging a screen door? Let's say materials for a deck cost $1200, then I usually charge $1200 for labor, making the estimate $2400. Am I over charging that way or leaving money on the table? or how much should I be making per hour as a residential carpenter with 20 years experience. Your help is greatly appreciated. I feel as though Iam being taken advantage of by working for $15/hr as an skilled carpenter but I have nothing to reference it by. Thank you in advance for your insight and knowledge, Sincere!y, Anthony
