A car came into 1Stop Motor Shop Mallusk with its interior flooded due to a water leak. Here’s how we diagnose and repair water ingress problems for Newtownabbey drivers.
When water makes its way inside your vehicle, it’s more than just an inconvenience — it can cause electrical faults, mould, corrosion, and even damage your car’s control units.
This car arrived at 1Stop Motor Shop in Mallusk completely flooded inside. The carpets were soaked, and water was pooling under the seats. We began a full diagnostic to locate the leak and prevent further damage.
Interior leaks can come from several sources, including:
Blocked drainage channels around the windscreen or sunroof
Perished door or boot seals
Faulty body vents or grommets
Poor previous repairs or panel sealing
Using specialist leak detection techniques — including controlled water testing, pressure smoke testing, and visual inspection — we trace the exact source of the problem.
In this case, we’re currently drying the interior and running a step-by-step inspection to identify whether the leak is coming from the doors, boot vents, or rear quarter panels.
Leaving a leak untreated can lead to:
Electrical system damage (especially in modern cars)
Mould and damp smells
Rusting floor pans and seat mounts
Fogged windows and condensation issues
Even a small leak can cause hundreds of pounds worth of damage if left unchecked. Acting quickly protects your car’s value and safety.
Step 1: Diagnose the leak using controlled testing
Step 2: Dry out the interior safely
Step 3: Repair or replace damaged seals or vents
Step 4: Recheck for watertight sealing before returning the vehicle
