How to Repair RV Window Leaks

How to Repair RV Window Leaks
Whenever it rains or you wash your recreational vehicle (RV), it is wise to inspect the window seals to make sure water isn't coming in or getting trapped in the walls. It isn't enough to wipe up or mop the water that accumulates. Untreated window leaks can lead to mold and dry rot inside your RV's walls, and the cost to repair this damage can run in the thousands of dollars. It doesn't take much time or money to shore up these leaks and keep your RV dry.


Difficulty: Moderate

Things You’ll Need:
  • Caulk
  • Caulking gun
  • Rubber gloves
  • Razor blade
  • Window cleaner
  • Masking tape
  • Screwdriver
Step 1
Insert a razor blade behind the caulk on the window pull it along the window until the caulk comes off in a piece big enough to grab and pull. You should be able to pull off the rest of the caulk in a couple of pieces.
Step 2
Clean the outline of the window you will be caulking with a window cleaner to remove dust and sediment.
Step 3
Use masking tape to cover the areas you do not want caulked, about 1/8 of an inch from the edge. If you have experience with caulking and are confident in your aim, you do not need to do this.
Step 4
Cut the caulk container as close to the tip as possible to create the smallest bead. Use a nail or small screwdriver to break the container's inner seal.
Step 5
Move the caulking gun along the perimeter of the window, as deep into the crevice as you can go. Wear a rubber glove and use your finger to smooth the caulk and wipe away any excess.
Step 6
Allow caulk to set for 24 hours before removing the masking tape or letting water come into contact with the caulk.
