Tracking and Fixing a Subfloor Leak – Charlestown
A real Charlestown case of a tricky subfloor leak and how our team resolved it.
Background
A homeowner in Charlestown called us after noticing damp patches on a few internal walls, especially after heavy rain. They’d already had a couple of inspections, but no one could say for sure where the water was coming from. With the damage getting worse, they contacted Leak Hunters, specialists in leak detection, for a proper diagnosis.
Initial Leak Testing
Our Newcastle plumbers carried out an inspection of the home and surrounding property. Moisture readings confirmed a strong link between the leaks and storm events. Everything pointed to water getting in underneath the house and creeping into the internal walls.
Our Leak Detection Process
Our inspection showed poor drainage under the home was the main cause. Rainwater was pooling below the structure and slowly finding its way inside. By carefully assessing the property layout and drainage flow, we tracked the leak right back to its source.
The Challenge
The main challenge was that the signs of damage were inside the home, but the actual leak was hidden underneath. The situation required experience, the right tools and precise leak detection.
The Work we Carried out
To fix the problem, we installed a drainage redirection system beneath the home to keep water away from the foundation. We also sealed the entry points and waterproofed the area to stop any future seepage. These steps not only stopped the internal damage but also helped protect the home long-term.
The Result
Redirecting the water away from the foundation stopped the damp from reaching the internal walls. We walked the homeowner through what had caused it and what we’d changed, so they understood why the repair would hold rather than just being told it would. A subfloor leak rarely shows itself where it’s happening, which is why the diagnosis matters as much as the repair.
