Water damage is the slow killer of RVs in Port St. Lucie. The combination of summer thunderstorms, the salt-laden Atlantic breeze, and Florida humidity that can hide leaks for years makes it the single most expensive maintenance category for RV owners across St. Lucie County. The good news: every type of water damage starts with telltale signs you can spot before structural damage sets in. Here are the eight warnings to check this weekend.
Sign 1: Soft Spots in the Floor
Walk every square foot of the rig. Pay extra attention to the area in front of the entry door, under slide rooms, and around the toilet and shower. Any spongy feel under your weight means the sub-floor has absorbed water and the structural plywood is delaminating.
Soft floor near slides is usually a slide-room seal issue - the wiper seal failed and water has run down the wall and pooled at the floor. Repair runs $1,500 to $4,000 depending on how far it's spread.
Sign 2: Brown Rings or Stains on Ceilings
Inspect every ceiling panel from inside the rig. Brown rings are dried water - they mean a leak above is active or recently active. Common locations: AC unit, vents, skylights, antenna mounts, refrigerator vent.
Don't paint over the stain. The water that caused it is still finding a path. Find the leak first.
Sign 3: Bubbled or Delaminated Wall Paneling
Run your hand down every interior wall, especially in slide rooms and corners. Any bubble, ripple, or wave in the paneling is water that has wicked into the lauan backing.
Once paneling delaminates, it's cosmetic repair only - the original wall is unsalvageable. The fix is reframe and replace at $400 to $1,200 per panel.
Sign 4: Musty Smell
Open the rig after it's been closed up. A musty or moldy smell means active mold growth somewhere - usually behind paneling or under flooring. Florida humidity gives mold the perfect growing environment.
Mold remediation runs $400 to $1,500 depending on extent. Add the cost of fixing the underlying water source.
Sign 5-8: Roof, Slides, Storage, Windows
Climb onto the roof and inspect every penetration. Cracked Dicor sealant means water is getting in. Check slide-out wiper seals from outside while the slide is extended - they should be supple, not cracked. Open every storage compartment and look for water staining at the bottom corners (a common sign of leaking storage door seals). Inspect window frames from inside for rust streaks running down the wall - that's water past the frame seal.

Why Florida Hides Water Damage
In dry climates, water damage shows up fast - wood gets wet, wood gets dry, wood cracks. In Port St. Lucie's high-humidity environment, wet wood stays wet for months, slowly rotting from the inside without showing visible signs. By the time the floor goes soft, the joists below may already be compromised. Annual inspection is the cheapest insurance you can buy.
