How long will shutters last and what are the maintenance issues?

Similar to any good piece of joinery or well made piece of furniture, shutters will last a life time and more. They will not deteriorate like curtains and won't need to be taken down for periodic laundering. They will not harbour mites or smell of unpleasant odours. In fact the only maintenance will be a dusting from time to time, which is best done with the brush attachment on the end of a vacuum. Virtually maintenance free with longevity, which makes it a 'no brainer' when coupled with aesthetic and practical reasons.
