What are the signs of a hidden leak, and how is it actually found?
An unexplained rise in your water bill, damp patches, a musty smell, or a boiler that keeps losing pressure are worth investigating - and visual inspection, pressure testing and specialist equipment are used together to narrow down exactly where the leak is.
Some signs are obvious, like a visible damp patch, while others are easy to miss - a slightly higher water bill than usual, or a boiler that needs topping up more often than it used to. None of these confirm a leak on their own, but together they're a reasonable prompt to get a proper check done before any damage gets worse. The starting point is usually a visual inspection of accessible pipework, followed by pressure testing to confirm whether the system is losing water and roughly how quickly. Where the source still isn't clear, more specialist methods help narrow the search further before any repair work begins - the goal throughout is finding the source accurately rather than opening up more of the property than necessary.
