Although showers or shower baths may leak for a number of reasons, by far the most common cause of leakage is building movement:

1. As a building settles into its foundations
2. As a building moves naturally with hot and cold weather

This movement can result in weakening or cracking of grout, tile and floor/wall junctions within the shower or bath. This eventually allows water to penetrate beneath the surface of the tiles.

Beneath the surface of the tiles there is usually some kind of waterproofing membrane designed to catch/stop water penetrating to surrounding areas. Unfortunately, these membranes are also susceptible to building movement, poor installation and chemical breakdown with age. Once this membrane has been breached, water is free to penetrate into surrounding areas and cause damage.

1. Swelling skirting boards, dampness, or mould build up
2. Peeling paint: ceiling, bathroom OR outside wall
3. Damp musty smell – wet carpet and wallpaper
4. Mouldy cupboards, ceilings and walls
5. Stained timber under the house or subfloor
6. Cracked tiles in the bathroom
7. Missing grout
