I am doing an estimate for work in a home. I am going to paint a bunch of 8 pane over 8 pane windows. They are in pretty good shape, not much prep work , no putty is needed, a tiny bit of scraping and oil base priming to raw wood wood . I am doing both interior of the windows and exterior of the windows. The bulk of work I am performing is to paint these windows, Usually I get jobs that you to paint whole rooms and if I am off on my window paint time estimate it won't kill me. This job is all windows so I want to get it right and not get killed on labor time. I am an experienced painter and do good work. Can Any body give me a clue on how to estimate this job? Also, All work is on the first floor so NO 2cd story work.

Also I forgot to mention I will do my spot priming and I intend to do two finish coats. I would sure appreciate some help on this one

I would paint something identical to one of the panes at home, then multiply. Then add some time for problems you can't foresee. Do not be tempted to assume that the work will go faster once you hit your stride or similar.:) I think you are right to be careful about estimating this job.

I used to paint houses and I am a self employed contractor in another field, so that's why I am answering this question. I'm sure you'll get different answers, but this is one approach to your problem.

Good luck!
