# RV Fiberglass and Delamination Repair in Chino

> OCRV Center repairs cracked fiberglass caps, bubbled sidewall delamination, and impact damage on motorhomes, fifth wheels, and campers across Chino. Delamination repair generally runs from $1,500 to $20,000 depending on how far the moisture spread.

Delamination starts quietly. A pinhole in a seam lets water wick between the fiberglass skin and the luan and foam behind it, the bond lets go, and the wall starts to bubble and wave. The fix is to find every soft area, remove the failed core, rebond fresh laminate, and refinish.

## Signs your RV has delamination

Owners often notice one symptom and assume it is cosmetic, but delamination is moisture spreading from a failed seal. Catching it early keeps the repair to a contained section at our Yorba Linda shop, not a full wall.

- Wavy or rippled look across the sidewall in raking light
- Soft or spongy spots when you press on the panel
- Bubbling or lifting around windows, seams, and the cap
- Cracks that keep returning after a surface patch

## How we repair fiberglass and delamination

We map the affected area, often larger than it looks, then remove the skin, replace the wet core, and rebond with the right resin and pressure. Once the structure is solid we fill, fair, and refinish so the panel reads flat. On caps we can repair cracks and impact holes or replace the entire cap when the damage is beyond repair.

- Moisture mapping to find the full wet area
- Vacuum or clamp rebonding with marine-grade resin
- Wet luan and foam core replacement

## Frequently asked questions

### What causes RV delamination and can it be stopped?

It is almost always water intrusion through a failed seam, window seal, or roof edge. Once the bond fails it spreads, so the real fix is to repair the laminate and then seal the source. We do both, because a cosmetic patch over a live leak will just bubble again.

### How much does fiberglass delamination repair cost?

It depends on how far the moisture traveled. A small contained area can be a few thousand dollars, while a full sidewall with structural core damage can reach $20,000 or more. We open and inspect the area first so the estimate reflects the real extent, not a guess.

### Is a bubbled sidewall worth putting off?

Not for long. The trapped moisture keeps breaking the bond and softening the core, so a small bubble this season can become a structural repair the next. We replace the wet core and seal the entry point.
