I need to have about 30 metres of fencing replaced. One fencer is really keen on Jacksons fencing and their 25 year guarantee looks great. However it's all timber - posts, gravel boards.
I had thought of going with concrete posts and gravel boards for longevity. The existing fence has timber posts and gravel boards and has lasted twenty years (with some concrete spurs on the posts a few years back).
Everyone seems to be going for concrete - is this an environmental and aesthetic disaster? Are some posts (eg Jacksons) genuinely almost as good as concrete, but look nicer as wooden?
Which would you choose?
