Leaking Shower Repairs
Find out what’s causing the leak and what needs fixing.
A leaking shower can damage nearby walls, floors and timber if it’s left unattended. If you’ve noticed damp patches, swollen skirting boards or water outside the shower, it’s worth getting it checked.
Based in Brookvale, Petrolo Construction Group provides leaking shower repairs across Sydney’s Northern Beaches and North Shore.
Sam brings more than 20 years’ industry experience, with a background in carpentry, tiling and bathroom renovations. We assess the problem, explain what we find and talk you through the repair options before work begins.

Signs your Shower May Be Leaking
Things worth checking include:
-
Damp Patches or Peeling Paint: Stains, bubbling paint or moisture on walls near the bathroom.
-
Swollen Timber: Skirting boards, door frames or architraves that are swelling, softening or deteriorating.
-
Cracked Grout or Loose Tiles: These need checking, although they don’t necessarily mean the waterproofing has failed.
-
Persistent Musty Smell: An ongoing damp smell in or around the bathroom.
-
Wet carpet or flooring: Unexplained moisture in an adjoining bedroom or hallway.
These signs can have more than one cause. An assessment helps establish where the water is coming from and what work may be needed.
Does a Leaking Shower Need Tiles Removed?
It depends on the cause of the leak and the condition of the shower.
Some problems may involve worn silicone, shower screen seals or plumbing. Others involve the waterproofing beneath the tiles. Replacing grout or applying a surface sealer won’t repair a failed waterproofing membrane.
If waterproofing work is needed, tiles may need to be removed to access the affected area. The extent of the repair depends on what we find and whether the existing waterproofing can be reliably connected to the new work.
We’ll explain whether a localised repair is suitable or whether a larger section needs rebuilding. We’ll also discuss tile-matching options, as an exact match isn’t always available.

Experience in Tiling, Carpentry & Bathroom Renovations
Sam’s experience in both carpentry and tiling is useful when a shower leak affects more than the tiled surface.
Our bathroom renovation background helps us assess how the shower, waterproofing, flooring and surrounding timber fit together. If damage is uncovered during the repair, we can explain what needs attention and coordinate the work required.
You’ll get a straightforward explanation of the problem and the proposed repair.


Our Shower Repair Process
We start by assessing the shower, then agree on the work needed before proceeding.
-
Inspect the Shower: We look at the shower and surrounding areas, discuss where you’ve noticed moisture and check for likely sources of the leak. Further testing or opening up part of the shower may be needed to confirm the cause.
-
Explain the Options: We talk through our findings, the proposed repair and the costs involved. If plumbing checks or other specialist work are needed, we explain those as well.
-
Carry out the Repair: Depending on the problem, the work may involve seals, plumbing, tiling or waterproofing. Where tiles need removing, we check the exposed surfaces and discuss any additional damage before carrying out further work.
-
Finish and Check: We complete the agreed work, check the repaired area and explain any drying or curing time before the shower can be used. We also provide relevant documentation and care advice.
Careful Work, Whatever the Repair
A smaller repair still needs proper preparation and attention to detail.
We take care with the surfaces beneath the tiles, the waterproofing work involved and the final finish. We also protect the surrounding area and tidy up after the job.
If removing tiles reveals more damage than expected, we’ll explain what we’ve found and discuss any changes to the work and cost before proceeding.


Repair the Shower or Renovate the Bathroom?
A leaking shower doesn’t automatically mean you need a new bathroom.
If the problem is contained and the rest of the bathroom is in good condition, a repair may be the sensible option. If damage is more widespread, or you were already planning an update, it may be worth considering a larger renovation.
We’ll help you weigh up the condition of the bathroom, the scope of the repair and your budget. Age alone doesn’t determine the answer.
Because we handle both shower repairs and bathroom renovations, we can explain the options and help you decide what makes sense for your home.
