Delamination Repair in Fountain Valley, California
What this work involves
Delamination is a water problem that presents as a cosmetic one. Water enters at a failed seal, tracks between the skin and the luan substrate, and breaks the adhesive bond. By the time the sidewall visibly bubbles, the debonded area is typically two to four times larger than what you can see.
How we approach it
- Tap testing and moisture meter mapping on every panel before quoting, so the number reflects the real area.
- The water entry point is found and corrected, otherwise the repair fails again in a season.
- Vacuum bagging rather than screw-and-clamp, which is why these repairs hold flat.
- Substrate is verified sound; rotted luan gets replaced rather than bonded to.
What sends people here
- Bubbling or waviness visible in low angle light
- A hollow sound when tapping across the wall
- Soft spot under hand pressure
- Staining or a musty smell inside the adjacent cabinet
Questions
Questions about delamination repair
How do you repair delamination on an RV?
Map the debonded area by tap testing, drill small injection ports, inject structural adhesive, then pull the skin flat with vacuum bagging while it cures. Ports are then filled and the surface refinished. The critical step people skip is finding and fixing where the water came in.
How much does delamination repair cost on a fifth wheel?
A contained area on one panel runs $1,500 to $4,000. A full sidewall runs $8,000 to $20,000. The spread is entirely about area and whether the substrate underneath survived.
