Why is water leaking from my shower tray or screen?

Tell us where water first appears and whether it happens as the tray fills, when spray reaches the screen or only with someone standing in the shower.

Match what you notice

The tray fills faster than it drains
We check the trap first, then the waste pipe. Where access allows, a camera can help locate a restriction. We check whether the pipe is supported and has a suitable fall. Clearing a blockage and correcting a sagging pipe are different repairs.
Water appears outside the door or frame
Limescale marks can show where water has been escaping. We test one corner or joint at a time, then check door alignment, seals, rollers and frame joints. A worn seal or roller may be replaceable if matching parts are available. If the tray is out of level, the tray and screen may need refitting together.
There is a damp patch on the ceiling below
We may ask you to leave the shower unused before the visit. We test the drain first, then the seal around the waste, the tray corners and the screen joints separately. We look below through existing access where possible and may use a moisture meter or camera. We agree any opening of the ceiling or floor first.
It leaks only when someone stands in the tray
We check for movement under load. If the tray flexes, the waste seal can open or the perimeter seal can pull away. We check the support and discuss refitting if needed. If the tray itself is cracked, we discuss replacement.

Reseal, refit or replace?

We prepare the surface, choose a compatible sealant and follow the enclosure instructions so any drainage openings stay clear. We tell you when it can be exposed to water. After the first shower, let us know if water reappears.

Access under the tray

A raised tray may have a removable panel. A flush tray can require access from below or through adjoining finishes. We check if the screen can be reused and whether matching tiles are available. Leave the shower out of use if water reaches the room below, and keep clear of wet electrics and bulging ceilings.
