- Visible mold spots
Start by inspecting both inside and outside the window frame carefully. Look for cracked or brittle rubber seals (gaskets), gaps in sealant beads, or loose rivets. comparing window brands like Dometic, Seitz, and Polyvision use high-quality seals, but over time, even the best materials can degrade due to UV exposure, temperature changes, and vibration.
Step 1: Perform a Controlled Water Test
A simple, effective way to find leaks is to spray water over your campervan window while someone watches inside for moisture. Use a hose or spray bottle, and follow this pattern:
| Spray Pattern | Purpose |
|---|---|
| Bottom to top | Checks seal and drainage areas |
| Around corners | Tests frame junctions |

- Moisture meters to detect wet spots behind panels
- Infrared thermography cameras to find hidden damp areas
These tools help avoid unnecessary repairs by targeting the exact problem.
Understanding Campervan Window Seal Failure
The most common leak culprit is worn-out seals. Rubber gaskets and sealants like butyl tape or polyurethane break down over time. Here’s what to look for:
- Cracks, gaps, or brittle sections in seals
- Loose or missing sealant beads
Temporary Fixes You Can Try
- Apply self-amalgamating silicone tape over small cracks
- Use an exterior-grade silicone sealant as a quick patch

Permanent Repair: Step-by-Step
- Remove old sealant and rubber seals carefully — Use plastic scrapers to avoid damaging your window frame.
- Clean the bonding surfaces thoroughly with isopropyl alcohol or a dedicated cleaner.
