Don’t Ignore That Leak: How Water Damage Can Hide Behind Your Bathroom Tiles

A small leak behind your tiles might not seem urgent – but it can quietly lead to serious problems if left unchecked. What starts as a minor issue can grow into expensive water damage.
So how do you spot a hidden leak?
Here are some early signs to look out for:
Tiles that are cracked, loose, or hollow-sounding
Grout that’s missing, mouldy, or deteriorating
Skirting boards or door frames that feel soft or swollen
Damp carpet near the bathroom
A persistent musty or damp smell
What Can Happen Over Time
If left untreated, a hidden leak can:
Weaken your walls, making them prone to cracking or sagging
Cause tiles to loosen, crack or fall off
Encourage mould and rot that spreads behind the wall
Break down waterproofing layers
Lead to structural issues and expensive repairs
