Last time the outside of our house was painted it was done by a professional painter and decorator. I deliberately won't say when it was done as I'm after opinion as to how long it should generally last before it needs re-doing.
Some of the paintwork has started to peel on a couple of windows and the back door needs completely sanding and repainting. Also the 3 wooden door thresholds which were painted with wood stain are all in a bad state. The painter came highly recommended to us by another trusted tradesman but we can't remember paint work needing to be done again so soon in the years we've been living here. So my question is, how often would you expect exterior woodwork to need painting? (The flaking paint is on 3 sides of the house so not all South/North facing).
