A leaking shower is one of the most common — and most damaging — plumbing problems in Sydney homes. Left untreated, a shower leak can destroy tiles, rot timber framing, damage floors, cause mould growth and lead to expensive structural repairs.

Jayco Plumbing provides fast, accurate and long-lasting shower repairs for homes, units, townhouses and commercial properties across Greater Sydney. We don’t patch over problems. We diagnose the real cause and repair your shower properly so the issue doesn’t return.

Whether your shower is leaking through tiles, dripping behind walls, backing up into drains or causing damp patches in adjoining rooms — we’ll find the source and fix it safely and cleanly.

    A proper diagnosis is the difference between a one-time fix and recurring leaks.

    1. Leaking Shower Screen

    Silicone breakdown, cracked frames or failed seals allow water to escape.

    2. Failed Waterproofing

    The most common cause of shower leaks in Sydney — especially in older bathrooms.

    3. Mixer Tap Leaks

    Worn cartridges cause water leakage inside the wall cavity.

    4. Tile Cracks & Porous Grout

    Water seeps through tiles and grout into the wall/floor.

    5. Leaking or Blocked Shower Drain

    Causes:

    • Standing water
    • Slow drainage
    • Odours
    • Backflow

    Movement cracks the waterproofing layer beneath tiles.

    6. Shower Base Movement

    Movement cracks the waterproofing layer beneath tiles.

    7. Leaking Shower from Upstairs Bathrooms

    Often shows as:

    • Stains on ceilings
    • Bubbling paint
    • Sagging plaster

    Behind-wall copper or PEX leaks cause ongoing water damage.

    8. Hot & Cold Pipe Leaks

    Behind-wall copper or PEX leaks cause ongoing water damage.

    Whatever the issue, we identify and resolve it properly.

    Signs Your Shower Is Leaking

    If you notice any of these, you likely have a leak:

    • Water pooling outside the shower
    • Damp or swollen skirting boards
    • Mould or musty smells
    • Cracked, loose or hollow tiles
    • Paint bubbling on nearby walls
    • Stains on ceilings
    • Water damage on the other side of the wall
    • Constant wet patches
    • Tiles that never dry
    • High water bills
    • Dripping sounds behind walls

    A leaking shower never fixes itself — it always gets worse.
