🚿 Q&A: Can I just re-seal a shower that has missing grout or silicone?
❓ “My shower has missing grout and cracked silicone… can’t I just re-seal it?”
💡 You can—but it’s usually only a short-term fix that could turn into a larger problem later.
❓ “Why is that a problem?”
💧 Missing grout or failed silicone usually means water has already found its way behind the tiles. Re-sealing the surface doesn’t fix what’s happening underneath.
❓ “What’s the risk if I just patch it?”
⚠️ Moisture can continue spreading behind the wall, leading to mould, loose tiles, timber damage, leading to a full waterproofing failure.
❓ “So what should I do instead?”
🧱 If you’re already seeing multiple areas of deteriorating grout, cracked silicone, loose tiles or recurring moisture issues, patch repairs may only provide a temporary fix. The most reliable solution is to engage a qualified tiling and waterproofing professional to properly assess the condition of the shower. A thorough inspection can determine whether the issue is limited to surface finishes or if there are underlying waterproofing failures that require a more permanent repair solution. Addressing the root cause early can help prevent further damage and avoid more costly repairs in the future.
❓”My shower tiles are already lifting l, does this mean I need a shower renovation?”
👷♂️ Yes - or at least a full inspection is needed.
Lifting tiles are a common sign that water has already breached the waterproofing behind the tiles.
Once that happens, surface repairs like re-grouting or re-sealing won’t address the underlying issue.
💡 Bottom line:
Re-sealing can make it look better temporarily… but it doesn’t always make it safe again.
A proper assessment will save you from repeating the same problem—and potentially costing you more later.
