Stop Shower Leaks Before They Damage Your Bathroom

A small leak around your shower tiles or shower screen might not seem like much—but over time, it can cause extensive damage to your property. From mould to structural decay, leaky showers is one of the most common (and costly) issues we see. At Leaky Showers, we specialise in shower repair, using proven shower sealing methods to stop leaks without removing tiles.

Whether you’re dealing with failed waterproofing, which is actually the root cause of a leaking shower, cracked/fractured grout and worn silicon and sealants inside the shower, allows too much water to get behind the tiles, which in turn will deteriorate the tile glues and cause mold issues and tiles to come away. 

Resealing the shower is also done when a shower is not leaking into adjacent rooms, but the grout sealants and other materials have deteriorated to prevent major issues.

Why Shower Sealing Matters

Leaks typically occur where the shower walls meet the floor, or around fixtures like the shower screen. These high-movement zones require flexible material, not just grout. DIY fixes often miss the mark because they fail to properly seal joints or use the wrong type of sealant.

Unchecked leaks can lead to:

  • Rotting behind the wall or under the shower base
  • Persistent mould and mildew
  • Lifting tiles or cracked shower tiles
  • Costly insurance claims or rebuilds

Our team uses premium silicon sealant and precision tools to ensure every reseal results in a good seal—one that holds up over time and meets code standards.

Preparing to Reseal a Leaking Shower

Before any resealing begins, surface preparation is key. If you’re tackling this yourself, here’s how to prep:

  1. Clean all surfaces with a damp cloth to remove dirt.
  2. Dry thoroughly with a towel or paper to eliminate moisture.
  3. Use mineral turpentine to remove stubborn residue and old silicone fragments.
  4. Carefully remove old sealant with a utility knife.
  5. Mask off areas with tape to ensure clean lines.

Skipping these steps can result in sealant failure and recurring shower leaks.

Resealing the Shower Step-by-Step

With clean, dry surfaces ready, you can begin:

  • Load the silicone sealant into your gun.
  • Apply a steady bead along the gap where walls meet the floor or along the shower screen edge.
  • Smooth the line using a soapy finger or cloth dipped in mild detergent.
  • Remove masking tape for a clean edge.

Done properly, this process ensures a good seal that resists water intrusion and helps your bathroom stay dry and healthy.

Understanding Australian Building Codes

In 2021 there was some major changes to waterproofing standards NCC National Code of Conduct and  (AS 3740). After 1998, changes to Australian building codes require more rigorous shower waterproofing. In some states, only licensed waterproofers can perform sealing work, especially if the issue extends beyond the surface.

Why this matters:

  • Using non-compliant materials (like grout where flexible material is needed) can void insurance
  • Incorrect sealing can breach code standards
  • Compliance helps protect home value and safety

If your shower was built or renovated after 1998, it’s best to have it assessed before you reseal.

Common Mistakes in DIY Shower Repair

We’ve seen it all. The most frequent DIY errors include:

  • Applying silicone over old grout or failing to remove previous sealant
  • Using grout alone in high-movement areas
  • Ignoring minor signs of a leaking shower
  • Not checking joints around the shower screen or re tiled areas

These missteps usually result in continued leaks or even worse—hidden damage you won’t see until it’s too late.

FAQs

Can you reseal your own shower?
Yes, but DIY jobs often miss hidden leaks or use the wrong sealant. Professional resealing ensures long-term success.

How much does it cost to reseal a shower?
Professional resealing generally costs between $300 and $500, depending on the size and condition of the shower.

How often should you reseal a shower?
We recommend resealing every 3 to 5 years, or sooner if you notice cracked grout, water stains, or mould.

Re-Grout or Reseal? Knowing the Difference

Regrouting is useful for worn-out joints between shower tiles, but it doesn’t solve leaks in corners or floor junctions. For leak-prone areas, a flexible silicone sealant is essential. Sometimes, we recommend both re grouting and resealing to get the best result.
