Boat Dock Repair on Old Hickory Lake, TN
A dock on Old Hickory Lake works harder than it looks. This is a Cumberland River reservoir, not a still pond, so there is a steady through-current pulling on the anchor lines even on a calm day. Add the weekend wake traffic off Nashville and the fast level swings that come with a flood-control lake, and every float, cable, and weld gets exercised. Boat dock repair is the work of finding what has loosened, cracked, or filled with water, and setting it right before a small failure pulls the next one down with it.
Old Hickory Dock & Lift repairs floating docks across the lake: float replacement, cable and auger anchor resets, decking, frame welds, hardware, bumpers, ladders, and storm damage. We do it from the water so your dock holds its permitted position, and we quote the repair against the cost of a rebuild so you never pay to patch a dock that has reached the end of its frame.
Floats That Have Filled With Water
A corner riding low, a walkway that dips underfoot, or a dock that leans to one side almost always means a float has taken on water. The older docks on this lake ran bare foam billets that crack along the skin and wick water in until they lose lift. Tennessee practice now calls for encapsulated flotation, so a failed bare billet gets swapped for a sealed polyethylene float rather than nursed along. We pull the dead floats, check the ones carrying the extra load, and bring the deck back to level. A low dock is not just cosmetic: it drags hardware under and rots the frame from the waterline up.
Cables, Augers, and the Anchors Onshore
Docks here float and are tied to the bank with steel cables run to auger anchors, and in the shallower coves to pole or pipe anchors driven into the bottom. The connections are where the trouble starts. A stretched cable, a rusted eye, a shackle corroded through, or an auger that pulled during a high-water event all let the dock wander and snatch at its lines. We reset and re-tension the full anchoring layout, replace worn parts with hot-dip galvanized or stainless, and set the dock so it rides level through current, wake, and a rising pool.
Decking, Hardware, and the Parts Underfoot
Deck boards cup, gray, and back their screws out after years of sun and wet feet. Bumpers flatten, ladders bend, cleats work loose, and canopy frames corrode at the joints. These are the fixes that make a dock feel safe again, and most of them are same-visit work. We replace failed boards with material matched to your dock, upgrade fasteners to coated or stainless, and swap the tired hardware that turns a good dock into a worn one.
Welds, Frames, and Storm Damage
Steel-frame docks crack at the welds where the lake flexes them hardest, usually at gangway hinges and well corners, and a straight-line wind or a careless barge can fold a whole section. We re-weld cracked joints, straighten or replace bent members, and rebuild storm-hit sections. When a frame is rusting through in more than one place, we say so plainly, because there is a point where repair dollars are better spent on a rebuild.
What It Costs
Most single-system repairs run $1,200 to $1,800: a float or two, an anchor reset, a run of decking, a weld. Larger storm jobs and multi-float swaps are quoted per dock once we see the water. Every estimate is free and written down before anyone starts, and it tells you straight whether a repair or a section rebuild is the better money.

How much does boat dock repair cost on Old Hickory Lake?
A single-system repair usually lands between $1,200 and $1,800. That is the range for the everyday calls: a float or two that soaked through, an anchor cable that went slack, a run of deck boards, a cracked weld, or a bent guide post. When the fix list grows past three or four separate systems, rebuilding that section often beats chasing each failure, and the written estimate says so rather than billing you the long way.
Do I need a Corps of Engineers permit to repair my dock?
Routine like-for-like repair of an existing permitted dock generally does not trigger a new permit. Changing the size, adding a slip or a lift, or moving the dock does, because the Army Corps of Engineers administers Old Hickory Lake and its shoreline. We confirm your permit standing before we quote anything that changes the footprint, so the work stays inside the Corps Shoreline Management Plan.
Why did my dock shift after the lake came up?
Old Hickory is a Corps flood-control reservoir, so upstream releases can raise the level several feet in a short window. A fast rise loads the anchor cables and can drag an auger that was set too shallow. Most post-flood calls are an anchor reset and a re-tension, not a rebuild. We check every cable, eye, and anchor, reset what moved, and tension the system for the next rise.
Can you repair the dock in the water?
Most of it, yes. Floats, decking, hardware, bumpers, ladders, and anchor lines are all worked from a barge or off the dock itself. A pull is only needed for heavy frame re-welding or relocating the dock. Because the Corps manages shoreline access, we stage the work to keep your dock on its permitted spot rather than hauling it out.
How fast can you get to a repair?
It swings with the season. Spring and early summer fill the calendar fast. A float that is going down or a dock that has broken loose jumps the line, because a drifting dock damages itself and the docks beside it with every hour. Call, describe what you see, and we will give you an honest place in the queue.
