RV Slide-Out Seals Leaking
Signs of worn slide-out seals, how leaks form, and why seal replacement matters.
Wiper Seal Check
The rubber wiper should flip when the slide moves. If it stays folded in when extended, it funnels water inside. Use a seal conditioner to keep rubber pliable.
Corner Seals
Check the foam blocks or D-seals in the corners. These often compress or fall off, leaving daylight for water to enter.
