I perform a full diagnostic check, strip back the compromised sealants, and apply a specialised waterproof epoxy system.
Your shower is watertight and ready to use in 24-48 hours, saving you thousands of dollars compared to re-tiling.
Leaking Shower Repairs
A leaking shower doesn’t always mean you need a full bathroom renovation. In fact, in most cases, shower leaks are caused by deteriorated grout, failed silicone seals, or minor waterproofing issues—not faulty plumbing. Our leaking shower repair service is designed to locate and fix the source of the leak quickly and cost-effectively.
We begin with a thorough inspection to identify exactly where water is escaping. Once the issue is diagnosed, we remove compromised grout and sealants and apply a specialised waterproof epoxy system to restore the integrity of your shower.
This targeted repair method eliminates leaks without removing tiles, saving you time, money, and unnecessary disruption.
Most showers are fully watertight and ready to use within 24–48 hours. Our proven repair process prevents further water damage, protects surrounding structures, and extends the life of your existing bathroom—without the stress of a renovation.
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.

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:
