- Bumps under the windows
- Stains/discoloration (brown or rust) on the ceilings and walls
- Delamination (bubbling or waves on the sidewalls)
- Squishy or soft carpet areas
- Damage, staining, or buckling inside cabinets
- Soft spots around the roof
- If water is entering through the windows, apply new flexible silicone window caulking. The flexible caulking withstands and holds up to the vibrations caused by a moving RV.
- To quickly patch up roof and exterior siding leaks, you can apply a permanent waterproof tape called Eternabond which can be purchased at RV supply stores. Apply Eternabond tape carefully because once the adhesive backing sticks to your RV, it will not come off.
- For rubber roofs, paint on a coat of rubber roof repair.
- If the leak is coming from the air conditioner, make sure the AC is mounted tightly. Up to four bolts are used to hold the AC unit to the RV and one could have come loose. Tighten all bolts.
- To repair damaged wood:
- Pull off loose pieces
- Smooth the remaining wood with 80-grit sand paper.
- Liberally spray or paint on a wood hardener or epoxy resin. The wood hardener or epoxy resin soaks into the wood, halts the growth of mold, and hardens the wood.
- After 24 hours, use a putty knife to apply wood putty to the hardened wood. Use enough putty to fill in any indents in the wood caused by the water damage.
- Wait four hours for the wood putty to dry and sand the area smooth, using sandpaper.
If the damage is more serious than expected, a professional repair job from an RV repair shop is your best bet. You can also surf the Internet, as there are many videos posted by RV enthusiasts and professionals who will give you step-by-step visual instructions to help guide you through the process of identifying and repairing water damage.
