RV Fiberglass and Delamination Repair in Sebring, Florida

In Highlands County, fiberglass trouble is water trouble. Ultraviolet light chalks the gelcoat here as it does everywhere, but what actually brings the calls is delamination: the fiberglass skin separating from the substrate behind it because water got in and stayed. Sebring takes about 52 inches of rain a year, the muggy season runs from late April to mid-November, and a sidewall that gets wet does not dry out. We repair gelcoat cracks, crazing, small punctures, failed trim and seals, and localized delamination at your resort site, fish camp, storage lot, or driveway, and we find the water path first.

Delamination, and why it is a Florida problem

A laminated RV sidewall is a sandwich: a thin fiberglass skin bonded to luan plywood or foam, bonded to a frame, bonded to the interior wall. The bond is an adhesive, and it holds as long as the layers stay dry. Once water reaches the luan it swells, the adhesive releases, and the skin lifts into the bubble you can see and press. The water gets in at the edges: window frames, the roof-to-wall seam, trim strips, marker lights, the slide opening, an awning arm mount. It rarely gets in through the middle of a panel.

That is why the cheap version of this repair fails. Injecting adhesive into a bubble that is still being fed by a leaking window frame buys one dry season. The repair that lasts is: find the entry point, reseal it, confirm the substrate is dry, then re-bond. Whether a bubble is dry enough to inject is decided with a moisture meter on the day, and the roof repair and slide seal pages cover the two most common entry points.

What we repair on site

Localized delamination injection. Where the bubble is contained, the substrate is dry or can be dried, and the water path above it has been sealed, adhesive injection and clamping genuinely restores the bond. Runs $800 to $2,500 depending on area. We will tell you plainly if yours does not qualify.

Gelcoat cracks and crazing. Cracks are ground out to sound material, filled with matched gelcoat, cured, and sanded and polished back. Crazing over a wide area is assessed honestly: sometimes the right answer is a repair, sometimes a polish and a UV protectant, sometimes nothing at all. Spot work runs $200 to $600.

Small punctures and impact damage. Ladder strikes, low oak limbs on a fish camp lane, gravel damage, awning arm gouges. Repaired with glass and resin from behind where access allows, then finished from the front.

Trim, molding, and seal work. A surprising share of what looks like body damage is a trim strip whose sealant has failed, letting water behind the skin. Correcting that is often both the repair and the prevention, and it is the job we most often recommend doing on the same visit as a roof reseal.

Storm damage assessment. Highlands County took gusts near 70 mph from Hurricane Ian in September 2022 and was the second-hardest-hit county in Florida from Irma in 2017. Wind-driven debris, a torn awning that gouged the sidewall, a skylight or vent cover simply gone: we document it with photos and a written scope for your adjuster, and we tell you honestly which parts are mobile work and which are not.

What belongs in a body shop

We would rather lose the job than do it badly in a parking lot:

• Collision damage involving structure, framing, or alignment.
• Full sidewall or roof skin replacement.
• Anything requiring a paint booth for a full-panel or full-coach refinish.
• Delamination over large areas or with a wet, rotten substrate. Once the luan has rotted, injection has nothing to bond to.

If your rig needs one of those, we will tell you on the phone, usually from photographs, without charging a trip fee to deliver the news.

Cost, honestly

Everything above sits alongside the rest of our published pricing. Fiberglass is the one area where we quote more jobs after looking than before, and that is deliberate: the extent of a delamination and the moisture in the substrate behind it are not things a photograph reliably shows. A moisture meter does.

Why inland Florida rigs need this more than most

Three mechanisms, none of them dramatic on a given day:

Humidity that never lets go. From late April to mid-November the air here is muggy at least a third of the time and July averages 79 percent relative humidity. A sidewall that gets wet at a seam in June is still wet in September. In a dry climate the same leak would have evaporated between rains.

Rain volume. More than half the year’s 52 inches falls between June and September, much of it in afternoon downpours that hit the sidewalls sideways. Every seam is tested daily for four months.

UV on the gelcoat. Sebring’s July average high is over 91°F, and the gelcoat that protects the resin chalks and thins under that sun. A chalky surface no longer sheds water cleanly, which feeds the first two.

The practical defense is unglamorous: keep the gelcoat waxed or treated with a UV protectant, get cracks dealt with while they are small, and reseal windows and trim on a schedule rather than after a bubble appears. A spring roof reseal visit is the right moment to have the sidewall seams looked at, because the ladder and the trip are already paid for.
