*help* working 8-10 hours a house

Hey guys, I’m just starting to wash windows. Ive washed 2 houses so far and spent 8-10 ours on each, I’m wondering what I’m doing wrong. Most of that work is in window frame and sills.

I’m new so I don’t want to disappoint and feel like I’m “scamming” people so I put a lot of work into them. I don’t know what level of detail is expected. But I think I’m caring more than the client.

This was for 8 decent sized 2 pane windows and 3 double sliding glass doors. I’m also in Florida so lots of dirt and crannies in the frames/sills. These are upper-middle class homes that don’t get washed regularly

I’m sure my workflow will speed up a lot over time, but also can’t see how people do houses in 2-3 hours.

TLTR: I’m new, don’t want to short people on quality of work, how much do you make a dirty frame and sill look like new, vs do a decent job (quick rinse and wipe down). These homes aren’t washed regularly

Anyone whose experienced id really appreciate a pm to pick there brain, especially if they work in Florida. Thank you very much!
