Last time my house was painted (around 15yrs ago) it cost about 5k, including the scaffold. The exterior really needs repainting again now. What do you think about me doing it myself? I'm reasonably handy, though I'm aware I might get repetitive strain. It's a large 4 bed with loft conversion so I'd need a scaffold with 3 levels. I also wonder what's the best method to apply the paint? I don't want to use a sprayer. And I wonder will I get good coverage from two coats, or might the bad bits need 3?
