How Much Does It Cost to Reseal a Caravan in Australia?

We’ve all heard the saying: “If the van’s a-rockin’, don’t come a-knockin’.” But what if it’s leaking? Here’s what a caravan reseal will set you back.

Resealing a caravan in Australia typically costs anywhere from $300 for a single spot repair up to $4,500+ for a full reseal, depending on how much of the van needs attention. The exact caravan reseal cost will come down to the size of your van, its age, how hard it is to access the seals, and whether the old sealant needs to be stripped back first.

Below, we’ll break down what you can expect to pay for each type of reseal, what pushes the price up or down, and why Queenslanders in particular shouldn’t wait too long between checks.

Caravan reseal cost at a glance

Not every reseal job is the same, and the price tag will reflect that. Here’s a rough guide to what a caravan resealing cost looks like across the three main job types we see in our Arundel workshop.

Reseal type	What’s involved	Approximate price range
Spot reseal	One seal, window, or vent	$300 – $500
Partial reseal	A section of the roof or one side of the van	$1,000 – $2,500
Full reseal	The entire roof and body seals	$3,000 – $4,500+

These are ballpark figures. Every van’s different, so if you want to get an accurate caravan reseal price, then you’ll need to book in a proper inspection. This is what a van health check is for.

What affects the cost of resealing your van

A few things move the needle on your final quote:

• Van size: Bigger vans have more seals and more roof to cover
• Age of the van: Older seals are often more brittle and take longer to remove
• Access difficulty: Roof racks, solar panels, and awnings can all slow the job down
• Whether old sealant needs full removal: If it’s cracked or peeling, it has to come off before new sealant goes on, which adds labour time

If your van’s had previous DIY resealing attempts, factor that in too, as cheap sealant that wasn’t properly prepped often needs to be fully stripped before the team can start fresh.

Why Queensland vans need resealing more often

Here’s the bit a lot of van owners don’t realise: the “reseal every 6 years” advice you’ll see floating around isn’t a hard and fast rule, it’s more of an outer limit, and in the Sunshine State, it’s often optimistic.

UV exposure and humidity in Queensland break down sealant faster than in the cooler southern states, so seals here can start failing well before that six-year mark.

If your van spends most of its life parked outdoors on the Gold Coast or Brisbane, it’s worth getting your seals checked more regularly rather than waiting for a leak to tell you something’s wrong.

Signs your caravan needs a reseal

Here are a few tell-tale signs that it’s time to look at a caravan roof reseal. Look out for:

• Cracking or peeling sealant around windows, hatches, or the roof edge
• Water stains or damp patches inside the van, especially after rain
• A musty smell that wasn’t there before
• Sealant that’s gone hard, brittle, or discoloured

If you’re already seeing water damage in your van like our customer, Ryan, it’s worth thinking about our caravan water damage repairs service, as catching it early will make a big difference to your repair bill.

We’ve written a guide on the benefits of resealing your caravan roof, which we recommend checking out if you’ve been sitting on the fence about getting your seals sorted before hitting the road.

Is it worth doing it yourself?

Plenty of van owners are handy, and a small spot reseal is a reasonable DIY job if you’ve got the right sealant and a dry weekend. But full or partial resealing is a different story. Get the prep wrong, miss a spot, or use the wrong product, and you can end up trapping moisture rather than keeping it out. That’s usually a more expensive fix than if you’d had it done properly the first time.

It’s also worth getting your seals checked as part of a routine caravan service. Our team looks at your seal condition at every service, which means that small issues will get picked up before they turn into bigger ones.
