Annual RV Seal Inspection Checklist

Introduction

Seal degradation happens slowly — until it fails suddenly.

This article is part of the Low Maintenance RV Housing Framework, which focuses on converting older RVs into durable, affordable long-term housing through structural upgrades and failure prevention.

An annual seal inspection prevents:

  • Structural rot
  • Mold growth
  • Delamination
  • Costly repairs

Exterior Seal Points to Inspect

  • Roof seams
  • Front cap seams
  • Rear cap seams
  • Slide perimeters
  • Window trim
  • Clearance lights
  • Entry door frame

Signs of Seal Failure

  • Separation gaps
  • Dried cracking
  • Peeling edges
  • Mold staining
  • Rusted screws

Slide Seal Inspection

Inspect:

  • Wiper seals
  • Bulb seals
  • Top edge seams
  • Slide roof corners

Replace seals before they shrink excessively.


Seasonal Timing

Inspect:

  • Spring
  • Fall
  • After major storms

Conclusion

Preventative inspection is easier than structural repair.

Seal integrity equals structural longevity.
