J moulds are one of the biggest culprits when it comes to caravan leaks.
They run along some of the most vulnerable sections of the van, and once the seals start to weaken, crack, or separate, water can slowly make its way in without you even noticing.
The problem is, by the time you see signs inside the caravan, the damage may already be hidden behind the walls.
This is why regular inspections matter.
Find it early, fix it properly, and save yourself thousands in future repairs.
