Why Checking Your RV Seals Every Year Could Save You Thousands

When it comes to protecting your RV, few things are as critical—or as often overlooked—as your seals.

Every seam, window frame, roof edge, and slide-out on your RV depends on proper sealing to keep water out. Over time, exposure to sun, vibration, and temperature changes causes these seals to crack, shrink, or separate. And when that happens, water finds its way in.

Even a small leak can lead to serious and expensive damage. Hidden moisture can soak into wall panels, rot structural framing, and cause mold or delamination—issues that can cost thousands to repair. What’s worse, by the time you see staining or soft spots, the damage has usually been happening for months.

Annual Seal Inspections Protect Your Investment

That’s why it’s so important to have your RV seals inspected at least once a year by a qualified technician. A professional inspection involves checking every joint, vent, and window for cracks or separation, testing for moisture intrusion, and resealing where necessary. At Premier Boat & RV, we recommend scheduling your inspection before and after the wet season to stay ahead of potential issues.

Keeping a record of these inspections is just as important as the work itself. A simple service record or invoice noting that your seals were checked and maintained can make all the difference if you ever need to file an insurance claim.

Why Insurers Care About Seal Maintenance

Most RV insurance policies do not cover damage that results from gradual water intrusion or lack of maintenance. If your RV suffers rot or interior damage and there’s evidence that the seals were never inspected or maintained, your insurer may deny the claim—classifying it as “wear and tear” rather than a sudden, insurable event.

On the other hand, if you can show that your seals were inspected and serviced regularly, you demonstrate due diligence and proper maintenance. That documentation often becomes the difference between a denied claim and a successful one.

Prevention Is Always Cheaper Than Repair

A routine seal inspection is a small investment—often less than a few hundred dollars—that can prevent repairs costing tens of thousands. It’s also peace of mind knowing that your RV is protected, your warranty or insurance remains valid, and your next trip won’t be ruined by a hidden leak.

If it’s been more than a year since your last seal inspection, now’s the time to schedule one. Whether your RV is stored indoors, outdoors, or on the road, regular seal maintenance keeps your investment safe and your insurance coverage secure.
