I have a client that needs a lot of tree work done. I met my tree subcontractor over there today, walked the property and went over the scope of work. My tree subcontractor gave me his quote which I marked up only 10% because she is an existing client. I submitted the estimate to my client. Her response was to ask if the tree company was a sub of mine? I said yes and that I only use them for tree work. She then stated that she would have to think about it because the cost of a subcontractor balloons the price and she believes that a subcontractor mark up is unethical? I let hear know that subcontractor mark up is an industry standard and what is covers. I let her know that a typical mark up could be 15% - 20%+. She then wanted to know if she could deal with my subcontractor directly. I would like to know some options on how you would deal with this. I am not new to subcontracting and have yet to have this happen.
