RESEALING YOUR CARAVAN
It is a distressing sight for the owner to see their van with aluminium and rot revealed beneath. Often just small symptoms can be clues to significant damage behind the cladding. Dark stains in corners, around windows and hatches or moisture sitting on window sills and ledges should be a catalyst for investigation. Sometimes water entry points may be obvious: cracked or missing sealant under moulds, flaking silicon on the roof or missing screws or rivets. But leaks are usually not specific and more likely result from the sealant being at the end of its life and no longer effective.
Prevention is better (and cheaper) than a cure!
By ten years of age every caravan must be inspected for sealant deterioration. Unfortunately some material becomes vulnerable as early as 6 to 8 years. Sealants used in the last 5 years are proving generally more durable; nevertheless inspect that stored or unused van regularly.
What Sealant Is Used?
A silicone with a high joint movement capacity.
Foam tape is used to seal some caravans. However, unfortunately, it has a limited lifetime. In these cases we remove the foam tape and refit windows or corner moulds with silicone. This provides a seal that should last 10 years plus.

ABOUT THE RESEAL PROCESS
To perform a full reseal we remove every window, all vertical corner moulds, all surface sealant on the roof, body top or pop top the caravan door and all fittings and access door, etc. All these items need to be cleaned up and replaced with new sealant between them and the body. Sometimes we need to scour the old sealant off and then repaint portions of the caravan. It is a laborious, time consuming and costly process but one absolutely critical to its future!
