Every RV has dozens of joints, seams, and penetrations where water can enter. The only thing keeping it out is sealant. When that sealant fails (and in Jensen Beach, it fails faster than anywhere in the northern half of the country), water gets behind your walls, under your roof, and into your floor structure. The resulting damage costs 10 to 20 times more to repair than the sealant service that would have prevented it.
Scott Marlins has been inspecting and resealing RVs in Jensen Beach for over 10 years. He knows exactly which products work in our climate, which fail, and where to look for the early signs of seal deterioration that most owners miss. A full exterior sealant inspection and touch-up is the single best maintenance investment you can make on your RV.
Where Sealant Matters Most
Roof penetrations are the highest-risk areas. Every AC unit, vent, antenna, solar panel, and cable pass-through that goes through the roof has a sealant joint around it. These joints are the first line of defense against water entry. In Jensen Beach, roof sealant takes the most UV punishment because it faces the sky with zero shade. We see roof sealant cracking and pulling away from edges within 3 to 4 years.
The roof-to-sidewall joint runs the entire perimeter of your RV where the roof meets the walls. This is typically sealed with a flexible lap sealant. When this joint fails, water runs down inside the wall cavity and causes the kind of hidden damage that doesn't show up until it's expensive. We check every inch of this joint during our inspections.
Window perimeters use butyl tape (for framed windows) or urethane adhesive (for bonded windows) to seal against the sidewall. These seals fail from UV exposure and thermal cycling. Water from a failed window seal runs straight down the inside of the wall, damaging insulation, framing, and interior panels.
Exterior lights, trim pieces, and accessories are sealed with various caulks and sealants during manufacturing. Many of these are low-quality products that fail within 3 to 5 years, especially in Florida. We replace them with UV-resistant, flexible sealants that last longer in our climate.
Pro Tip
Schedule your sealant inspection in spring (March to May) before storm season hits. Repairing a $50 sealant crack in April prevents water damage from June through October when Jensen Beach gets 70% of its annual rainfall.
Products We Use
Dicor self-leveling lap sealant is our primary roof sealant. It flows into cracks and levels itself, creating a smooth, waterproof surface over horizontal joints. It stays flexible for years and bonds well to EPDM, TPO, and fiberglass roof surfaces. We use the non-leveling version for vertical applications where flow isn't desired.
Sikaflex polyurethane sealant is our go-to for structural bonds and sidewall applications. It's extremely durable, UV-resistant, and maintains flexibility through extreme temperature ranges. It's the best product available for the roof-to-sidewall joint and high-stress connections.
Butyl tape is used for window reseals. It's the same product manufacturers use during assembly, and it creates a compression seal that's waterproof and remains flexible indefinitely. We use 3M and Heng's butyl tape products.
Geocel Pro Flex is used for specific applications where compatibility with existing sealants matters. It bonds to virtually every RV surface material and can be applied over most existing sealants (after cleaning), which makes it useful for touch-up work.
Pricing
| Service | Typical Cost |
|---|---|
| Spot reseal (2-5 locations) | $100 - $300 |
| Full roof reseal (all penetrations + perimeter) | $400 - $800 |
| Window reseal (per window) | $75 - $200 |
| Full exterior perimeter reseal | $800 - $1,500 |
| Sealant inspection only (with report) | $75 - $125 |
The Math That Makes Sealant Service a No-Brainer
Here are real numbers from our Jensen Beach service records. A full exterior sealant inspection and touch-up costs $150 to $300 per visit. Done annually, that's $150 to $300 per year.
A single roof leak that goes unnoticed for 6 months causes an average of $1,500 to $3,500 in water damage (wall rebuild, insulation replacement, mold remediation, and the roof repair itself). That's 5 to 12 years of sealant maintenance cost in a single repair bill.
We've never had an RV with up-to-date sealant maintenance need water damage restoration. Not once in 10+ years. The correlation is absolute. Maintained seals prevent water damage. Neglected seals guarantee it, eventually.
Florida Factor
In Jensen Beach, sealant fails about 40% faster than manufacturer estimates. A product rated for 7 years in "normal" conditions typically lasts 4 to 5 years here. Plan your reseal schedule accordingly, not based on the product label but based on Florida reality.

Exterior Sealant & Caulking Questions
How much does RV sealant service cost in Jensen Beach?
Spot resealing (2 to 5 locations) costs $100 to $300. A full roof reseal runs $400 to $800 depending on the roof size and number of penetrations. Complete exterior perimeter resealing (roof, windows, trim, lights) costs $800 to $1,500. These are the cheapest repairs that prevent the most expensive damage.
How often should RV sealant be replaced in Florida?
We recommend annual sealant inspections and touch-ups in Jensen Beach. Full resealing is typically needed every 3 to 5 years in our climate. That's about half the interval you'd see in northern states. Florida's UV index degrades sealant compounds faster than almost any other environmental factor.
What type of sealant do you use?
We use Dicor self-leveling lap sealant for roof applications, Sikaflex for structural bonds, butyl tape for window flanges, and silicone-based products for specific applications where flexibility is critical. The right sealant depends on the joint type, the materials being sealed, and the exposure conditions.
Can I reseal my RV myself?
Roof sealant touch-ups are doable for handy owners who are comfortable working on a roof. But there are common mistakes that cause more harm than good: using the wrong sealant type, applying over dirty surfaces, mixing incompatible products, and incomplete coverage. If you're not confident, it's cheaper to have it done right once than to fix a failed DIY job.
What happens if I don't reseal my RV?
Water gets in. In Jensen Beach, that means water damage, mold, delamination, and structural rot. A $200 annual sealant service prevents $2,000 to $5,000 in water damage restoration. We see this exact scenario play out every month on RVs that skipped their sealant maintenance.
How long does sealant last in Jensen Beach?
Self-leveling roof sealant lasts 3 to 5 years before needing touch-up. Butyl tape around windows lasts 5 to 7 years. Silicone-based sealants last 5 to 10 years depending on UV exposure. These are Jensen Beach-specific numbers. National averages are 30 to 50% longer because they don't factor in our UV and heat levels.
Do you check the entire exterior or just the areas I point out?
We check everything. Every roof penetration, every window perimeter, every exterior light, every trim piece, every compartment seal, and the roof-to-sidewall joint around the entire perimeter. Water finds the one spot you miss, so we don't skip any areas.
Can bad sealant void my RV warranty?
Many manufacturers require proof of regular sealant maintenance to honor water damage claims under warranty. If your warranty includes this requirement, we can document each service visit with photos and a dated service record that satisfies most manufacturer requirements.
When was your last sealant check?
Annual inspections prevent expensive water damage. On-site in Jensen Beach and Martin County.
