  • The good news is that you can fix the small patches and prevent them from spreading further. However, if the spread is too large, you must change the entire portion. Hence, it is essential to identify the rot’s extent.

Remove the rotting wood

  • Next, you must remove the rotting wood to start the process. This is a crucial step that needs patience and accuracy. Use a sharp object like a screwdriver or a chisel to remove the rotting wood. You can also use a knife or any other similar tool. Remember to be cautious while working with sharp objects and wear safety gear.
  • Try not to damage the surrounding area, but remove all the decayed wood until you find solid and healthy wood. You might need a cutter if you cannot access the rotting area.
  • In some cases, the rotten wood can be disproportionate. In that case, you must cut out a piece of healthy wood to simplify the replacement process. Cut out the wood in squares or rectangles since they are easy to work with.

Treat the remaining wood

  • The next step is to treat the remaining wood to prevent it from rotting further. You must use a preservative that enters the wood fibers and strengthens the remaining structure. You can also use a wood hardener for this purpose.
  • There are plenty of options available online when it comes to wood hardeners and wood preservatives. These products arrive at an affordable price, and they come along with the manufacturer’s instructions. Ensure to follow the instructions provided by the manufacturer.
  • Apply the wood hardener or preservative generously and ensure it is soaked into the remaining wood.

Replace the damaged wood

  • Next, you must cut a piece of new wood based on the rotting wood you removed. Get the same type of wood and cut it to the appropriate measurements. Ensure that the new wood is rot-resistant and matches the dimensions of the pieces that you removed.
  • The replacements must fit perfectly in the vacant space.
  • Next, you must secure the wood with the help of screws or adhesive. While some caravan owners use nails, it is advised to avoid nails and use screws or adhesive. Nails can split the wood and cause further damage.
  • An easy and effective tip is to use adhesive and screws together. This will secure the wood properly and make it easy to work while placing screws.

Seal the wood

  • Once you have replaced the damaged wood, it’s time to seal the wood. The easiest way is to apply waterproof sealant or paint to protect the repaired areas. Waterproof sealant is one of the best options to consider. You can also use both and give the new wood a decent paint job.
  • Apply enough sealant or paint to ensure they are good enough to prevent moisture and future wood rot. Choose a sealant or paint that is built for outdoor use. This will provide better protection and will extend the lifespan of the wood.
  • Give the wood a couple of extra coats to add more protection and ensure that you provide enough time for it to dry. Follow the manufacturer’s instructions when applying the sealant and paint.  

Inspect the surrounding area

  • Next, inspect the surrounding areas to check for any signs of wood rot. Be sure to inspect the areas thoroughly since wood rot can be hidden. Make sure to address these issues, if any, to prevent further damage.
  • Regular maintenance is the key to preventing wood rot in a caravan. Ensure the caravan is maintained regularly by checking for moisture leaks and other related damages. 
  • Work on the issue immediately to get rid of the wood rot. Be sure to check the areas around the windows and doors to minimize the risk of water seeping through the wood.
