Yeh skipping frames, missing windows, usual stuff
A combination of things I think, number 1 is having my work in the best order it can be.
number 2. i tend not to knock on doors when i turn up just crack on.
3. I've stopped writing prices on slips just have a pocket full and post as I'm finishing.
4. Slowly picking up work all the time, dropping any jobs that take too long/awkward parking/access etc.
5. Rinsing less, I worked with a lad for a few month who was much more slap dash than me, but to my surprise the windows still turned out fine...so now i rinse less.
6. Technique, for example sills get one swipe instead of 3, frosted glass doesn't need a rinse, don't clean something that ls already clean for example if a door is really clean just spray some water on it lol, top frames don't need cleaning every time..
Can't think of owt else at the minute, I think my works becoming more compact as I keep adding work and dropping the work that is further away or lower priced or just a pita..I think that's the main one, don't rest on your laurels just because you are full...refine, refine, refine.
