Lake life around Old Hickory, Percy Priest and Cheatham Lake puts constant stress on dock frames, boat lifts and gangways. Wave action, shifting water levels and everyday foot traffic loosen welds, crack aluminum and eat through steel supports over time. A mobile welder can repair most dock structures in place, without hauling a section off the water.
Common Dock Repairs We Handle
Cracked or bent aluminum dock frames and floating dock connectors, boat lift arms, cradles and support legs, gangway and walkway hinges, dock ladders, cleats and handrails, and brackets that have worked loose from repeated use.
Aluminum vs. Steel Dock Structures
Most floating docks and lift components are aluminum, chosen for its resistance to corrosion in fresh water — but it needs a different process and more careful prep than steel. Stationary gangways and larger support structures are often structural steel instead. Knowing which you have matters before any repair starts.
Why On-Site Repair Makes Sense
Draining a slip, craning out a lift, or trailering a dock section is expensive and slow. A mobile rig brings generator-powered welding equipment lakeside, so repairs happen right from the dock or a boat with minimal disruption to your water access.
What to Do
Don't wait on a cracked weld — wave action and winter ice only make it worse. A quick inspection can confirm whether it's a simple repair or something more involved, and a mobile welder can usually take care of it the same visit. Request a free quote and we'll come to you.
