We repair all water damage as well as seal leaks formed around roof hatches, windows, skylights, solar panels, air conditioners, shower and toilets. Our dedicated team inspect all entry points, replace sealants and pressure test your van to make sure it stays dry inside and out.
Whether you’ve noticed signs of water damage or just want peace of mind, we’re here to help.

The Cost of Ignoring Minor Leaks
Small leaks around the caravan often go unnoticed, until it has caused serious problems. This is why we recommend keeping an eye out for these major signs to help early leak detection and prevent costly repair damage. Signs like damp smells, soft walls or floors, or discolouration around seals should never be ignored. Even if you don’t see a leak, old sealants and exposed joints can allow moisture to slowly enter and accumulate behind walls or under roofs.
We focus on inspecting these high alert signals from your caravan and ensure you don’t experience any leak damage.Whether your van is used every weekend or stored for months at a time, regular waterproofing checks ensure you stay one step ahead of water damage.

Preventing Water Damage Before it Starts
Waterproofing doesn’t only mean making your vehicle rain-ready, it means protecting the core structure of your beloved caravan. Even one leak can mean rot, mould, insulation damage or electrical faults. Moisture can creep into wall cavities, under flooring, and around internal fittings, creating long-term damage that’s expensive to fix. Keeping your van sealed against moisture isn’t just about comfort, it’s about safety, durability, and value retention.
Here’s few reason why waterproofing benefits your caravan:
- Stops water ingress before it causes internal damage.
- Maintains structural integrity over the long term.
- Protects electrical and gas systems from corrosion.
- Helps preserve the resale value of your van.
