Coastal wind is the main reason fences fail here before they would inland: panels loosen, posts lean, and gravel boards rot at ground level faster than the rest of the fence. Most call-outs are for one of those three problems rather than a full fence replacement, so a single leaning post or a couple of blown panels can usually be fixed without touching the rest of the run.
Concrete postcrete is used for replacement posts rather than just packing soil back around them, since a post set in soil alone tends to lean again within a season on an exposed plot. Gates get the same attention: hinges re-hung square, latches adjusted so they actually catch, rather than just tightening whatever screw looks loosest.
Small structures like sheds, pergolas and raised beds are also handled, either repairing an existing one or building from a kit. A single fence panel replacement including post work typically runs from £90, with a full quote given after seeing the fence line and ground condition.
