Window installation needed

Murfreesboro TN

Description

Serious/ experienced only - I had a double set window rot out, and need help ordering/installing new windows. It is on a brick faced exterior wall, for which i can't figure out how to calculate window size with the angled sill. I did keep the old sill from the original window set. I am available to help as an assistant for install - it just turned into too big a job for me by myself. I have notes on measurements of what i think it should be, but need help. the image shows the brick around the windows, the windows shown have already been pulled out. Must be self insured for liability.
