Why Is My Shower Screen Leaking (and Can It Be Fixed)?
A shower screen leaks because of worn or perished seals, failed silicone, an incorrect floor slope, or gaps where the glass meets the wall. Seals and silicone are cheap fixes, often under $150 to $250, while a wrong slope or badly fitted screen usually means re-fitting or replacing. The right call depends on the cause, which a specialist confirms on site. Glazing Adelaide connects you with vetted local glaziers who diagnose the leak and quote the honest fix.
Key takeaways
- Worn seals and failed silicone are the most common and cheapest causes to fix.
- A floor that slopes the wrong way lets water escape and rarely has a cheap fix.
- Gaps at the wall junction usually point to a poor original installation.
- Reseal and new seals often cost under $150 to $250; re-fitting costs more.
- A specialist should confirm the cause before you spend on a fix.
Why shower screens leak
The most common culprit is a worn seal. The clear plastic or rubber strips along the door and base perish, harden and lose their grip over a few years, so water sneaks past where they used to block it. This is a wear item, not a fault, and it is the first thing to check on any leaking screen.
Failed silicone is the next suspect. The bead where the screen meets the wall and floor dries out, cracks or lifts, opening a path for water to escape and, worse, to get in behind the tiles. Discoloured, peeling or gappy silicone is a clear sign it needs redoing.
Less obvious causes include an incorrect floor slope, where the shower base falls away from the waste instead of toward it, and gaps at the wall junction from a screen that was never fitted square. Both usually trace back to the original build or install rather than normal wear.
Cheap fixes versus bigger jobs
The good news is that the 2 most common causes are the cheap ones. Replacing worn seals and re-running the silicone is straightforward work, often under $150 to $250 depending on the screen and access, and it solves the majority of everyday leaks. If your screen is only losing a little water at the door or base, start here.
The bigger jobs are the structural ones. A floor that slopes the wrong way cannot be fixed with a new seal, because the water is being directed the wrong way regardless. That usually means re-doing the shower base or re-fitting the screen to suit, which is a substantially larger cost.
Gaps at the wall from a poorly fitted screen sit in between. Sometimes packing and re-sealing solves it, but if the screen was cut to the wrong size for out-of-square walls, the honest fix is re-fitting or replacing it. A specialist can tell which of these you are dealing with once they see it.
When a leak means replace, not repair
A leak becomes a replacement conversation when the screen is old, the frame is corroded, or the water has already got behind the tiles and started damaging the wall. At that point spending on seals is putting money into a screen that is failing in more than one place.
It is also a replacement signal when the underlying cause is the screen itself, such as glass cut wrong for the opening or a badly designed configuration that always splashed out. Resealing the same mistake just delays the inevitable.
Rather than guess, get the cause diagnosed. Glazing Adelaide connects you with vetted local glaziers who inspect the leak, tell you whether it is a $150 seal job or a bigger fix, and quote honestly so you are not sold a full replacement when a reseal would do.

Frequently asked questions
A common seal-and-silicone repair often runs under $150 to $250, depending on the screen and access. Structural causes like a wrong floor slope cost more because they involve re-fitting or base work.
You can re-run the silicone, but if the real cause is worn seals, a wrong slope or a poorly fitted screen, fresh silicone only masks it briefly. Having the cause diagnosed first avoids repeating the job.
Usually yes, if the screen is otherwise sound and the cause is seals or silicone. If the frame is corroded, the glass was cut wrong, or water has damaged the wall, replacement is the better spend.
