At Caravan Waterproofing WA, we specialise in identifying and resolving waterproofing issues often overlooked during caravan manufacture and design.
Servicing Perth to Mandurah, we provide proven, long-term solutions that protect your caravan from water ingress, structural damage, and costly repairs.
Caravans are constantly exposed to harsh Western Australian conditions.
Without proper waterproofing, small issues can quickly escalate.
Our caravan waterproofing services are designed to strengthen vulnerable areas and ensure your caravan remains safe, dry, and road-ready.
Our goal is simple: identify vulnerabilities early and implement long-term solutions that protect your investment.
Roof-Mounted Air Conditioner Waterproofing Solutions
Roof-mounted air conditioners are common, but over time, vibration and movement can cause stress fractures, roof deflection, and water seepage — particularly around gasket areas or roof seams.
Our caravan roof waterproofing service across Perth to Mandurah includes the installation of a reinforced support plate to:
Reduce vibration stress
Prevent roof sagging and water pooling
Improve long-term sealing performance
This reinforcement is included in our standard service.
Caravan Roof Sheet Joint & Staple Leak Repairs
Due to standard roof sheet sizing, overlapping joints are common on caravans of varying lengths. These joints are often secured with staples, which can eventually push through the sealant and allow moisture into the roof cavity — frequently first detected in the front boot.
To permanently resolve this issue, we offer a reinforcing plate installation over roof joints and staples to prevent movement and sealant failure.
This upgrade is available at an additional cost.
J-Mould & J-Rail Waterproofing Upgrades
Standard J-moulds are not designed to be fully watertight. Rusted screws and hidden moisture are common signs of failure.
As part of our caravan waterproofing services from Perth to Mandurah, we now include:
Installation of a rope track into the J-rail
Sealing of all three exposed water entry points
This proven solution, inspired by leading off-road caravan designs, delivers superior water protection and durability.
Now included in our service price.
All our methods, materials, and procedures are selected specifically for Western Australian conditions to ensure long-lasting performance and peace of mind.
