Repair work on the side of the lake that takes the weather rather than shelters from it.
Wind on this lake generally arrives from the west and southwest, which means the Lincoln County shoreline is on the receiving end rather than in the lee. A dock here absorbs more energy per season than an identically built structure across the water, and that difference compounds over the life of the hardware.
The damaging condition is not the occasional storm. It is the routine afternoon build-up that arrives most warm days and works the structure for hours at a time. Storms produce dramatic failures; afternoon chop produces the slow loosening that precedes them.
Fastener condition at the frame connections, movement at the pilings, float attachment, and the state of anything on the exposed face. On this shoreline the windward side of a dock is reliably in worse condition than the leeward side, and pricing the job from the sheltered side understates it.
On average, yes, and the difference shows up in hardware rather than timber. Fasteners, brackets and float attachments do more cycles here, so they reach the end of their service life sooner.
Repair, in most cases, provided the pilings and framing are sound. Replacement becomes the honest answer when the structure has been moving long enough that the connections no longer hold.
