Replace or Repair the Dock

Unfortunately, boat docks brave all sorts of elements during their lifespan: constant moisture, Florida's heated rays of the sun, and beating waves during our periods of harsh storms. Over time, especially without regular maintenance, the look and the resilience can deteriorate. Extensive deterioration leads to an unsafe structure.  


It can be obvious that a boat dock replacement is necessary. In one of our earlier blogs, you will find how to determine when your dock is ready for replacement


An Aging Dock and Signs of Structural Damage

As we covered, not all docks are made alike, and the dock materials will greatly influence the lifespan of your dock. But, the signs will be there.

  • Cracks and warps can be a sign of structural damage. Pending on where and how much will determine the ability to repair or replace. 
  • Foundation deterioration can be extremely dangerous. In most cases, it points to total dock replacement.
  • The severity of rust in metal docks will determine if the dock's foundation remains safe.
  • Extensive rotting wood is a sign to replace the decking. Your pilings may be fine. Again, be sure to check for cracks and how deep they sit in the ground. Ground deterioration may leave them weakened and unsafe to support the decking, especially adding the additional weight of people. 

Common Dock Repairs

With regular inspection, you will find the problems to fix and repair. On ImproveNet, you will also find a great deal of information to help you make the right decisions. Some you may be able to do yourself, and others you will need the help of a professional.
