Whats your most profitable service?

We are primarily a window cleaning that also offers house washing, gutter cleaning, and roof cleaning. I guess I say we are primarily a window cleaning company because we did more window cleaning jobs than any other service this year. But as I sit and look at our crew hour times and what service was most profitable, window cleaning was at the bottom of the list. Gutter cleaning is by far our most profitable service. Im curious what your most profitable service is and what that looks like per crew hour for your company
