Our house is due for re-siding. We currently have white aluminum siding and, though we love the idea of replacing it with hardiplank, we are not sure it is worth the expense if we aren't staying in the house beyond five years. Also trying to decide whether to keep the classic white or change it to a grey. Our neighbourhood is full of 1950s homes, many of which are grey, white or brick. Would appreciate any and all advice for replacement siding and colour.
