How to Maintain RV Windows and Seals

Your RV’s windows let in light, fresh air, and great views—but they’re also common sources of leaks and drafts. Without proper care, seals can dry out, crack, or separate, leading to costly water damage. Learning how to maintain RV windows and seals keeps your rig watertight, energy-efficient, and comfortable.

Why RV Window and Seal Care Matters

Neglecting your windows and seals can lead to:

  • Water leaks and interior damage
  • Mold and mildew buildup
  • Drafts that strain heating and cooling systems
  • Foggy or cracked glass

If you already have leaking or damaged seals, Daisy RV offers resealing and window replacement services.

How to Maintain RV Windows and Seals

1. Inspect Regularly

  • Check seals every 90 days and before long trips
  • Look for cracks, gaps, or peeling caulking
  • Run your hand around the edges to feel for air leaks

2. Clean the Seals

  • Wash with mild soap and water—avoid harsh cleaners
  • Remove dirt and debris that can wear down the rubber
  • Dry thoroughly after cleaning

3. Condition the Rubber

  • Apply a rubber seal conditioner every 2–3 months
  • Keeps seals flexible and prevents UV cracking
  • Wipe away excess to avoid attracting dust

4. Check the Glass

  • Inspect for chips, cracks, or fogging between panes
  • Replace damaged windows before they spread
  • Keep glass clean with ammonia-free cleaners to avoid streaking

5. Reseal When Needed

  • Use RV-specific sealants for re-caulking
  • Apply self-leveling sealant for horizontal areas and non-sag for verticals
  • Smooth the bead for a tight, clean finish

6. Lubricate Moving Windows

  • Use a dry silicone spray on window tracks and latches
  • Avoid heavy oils that attract dust
  • Keeps sliding and crank-out windows operating smoothly

Extra Tips for Long-Lasting Windows

  • Use vent shades or covers to reduce UV damage
  • Keep blinds or curtains closed in storage for extra protection
  • Check after storms for leaks or water trails around the frame
  • Don’t forget emergency exit windows—test them periodically

Sealed Windows = Protected RV
