Grout Repairs & Drummy Tile Injection

Removing old, dirty grout and replacing it with stain-resistant Epoxy Grout for a waterproof, easy-to-clean finish.

If your floor or wall tiles sound hollow (drummy) when tapped, the adhesive has failed. Instead of ripping them up, I use an Epoxy Injection system to re-bond the tile to the substrate without breaking it.

Sourcing and replacing individual cracked tiles to match your existing floor seamlessly.

Grout Repairs & Drummy Tile Injection

Cracked grout and loose or “drummy” tiles are common warning signs of moisture problems in bathrooms. If left untreated, they can allow water to penetrate behind tiles, leading to leaks, mould growth, and costly structural damage. Our grout repair and drummy tile injection service restores strength and stability without the need for retiling.

We repair damaged or missing grout using durable, water-resistant materials that improve both appearance and protection. For hollow or loose tiles, we use a specialised injection method to re-bond tiles to the substrate, eliminating movement and preventing further deterioration.

This non-invasive solution is ideal for homeowners looking to extend the lifespan of their shower while maintaining its original look. By addressing these issues early, you can avoid expensive repairs and keep your bathroom safe, solid, and watertight.

Why Sealing Is Important

Sealing provides a protective barrier that is especially important in wet and high-exposure areas like bathrooms, showers, balconies, kitchens, and pool surrounds.

Reduces water absorption
Helps prevent mould and mildew growth
Minimises staining from soaps, oils, and minerals
Protects grout from crumbling and erosion
Extends the life of tiles, grout, and stone
Makes cleaning easier and more effective

Types of Sealers We Use

We assess each surface to ensure the most suitable sealer is used for maximum performance and longevity.

Penetrating (Impregnating) Sealers

These sealers soak deep into the grout or stone without changing the surface appearance. They:

Maintain the natural look and finish
Allow the surface to breathe
Provide long-lasting internal protection
Are ideal for bathrooms, showers, and outdoor areas

Surface (Topical) Sealers

These sealers form a protective layer on the surface. They:

Can enhance colour or sheen
Provide a visible barrier
Are typically used where a decorative finish is desired

FAQs About Leaking Shower Repairs & Tile Regrouting

Do I need to rip up my tiles to fix a leaking shower?

The majority of shower leaks are caused by failing grout or silicone, not the plumbing or tiles themselves. We use a specialised system to remove the old, compromised sealant and replace it with a high-grade waterproof epoxy and sanitary silicone. This repairs the leak and creates a watertight seal without the noise, mess, or heavy cost of a full bathroom renovation, making it ideal for homeowners wanting a quick and cost effective solution.

Who will actually be doing the work at my home?

When you book Coastal Seal & Grout, you get Nigel, the owner. We are a sole-trader business, not a franchise.

How much do shower, tile, and grout repairs cost?

The cost of leaking shower repairs, tile regrouting & cleaning, silicone replacement, and pool or outdoor tile repairs in the Sunshine Coast depends on several factors:
