Our Proven 3-Step Silicone Renewal Process
We don’t take shortcuts. We use a specific, proven approach to make sure your bathroom looks brand new and stays watertight:
Inspection & Assessment
Before we begin we inspect your bathroom's surfaces to detect any leaks, cracks, gaps, and to find out any water damage that requires attention.
Complete Removal of Old Caulking:
We carefully peel off the old, failed caulking of joints, corners and tiles. This involves intensive cleaning and an antifungal solution in order to ready the surface.
Final Clean-Up and Quality Check
We use high quality black diamond shower sealer or sanitary silicone, and tool it to a smooth and perfect finish. Our last examination is to determine that the site is fully insulated and dry.

Why Hire a Specialist Over a Handyman for Bathroom Caulking?
Thinking about calling a general handyman for bathroom caulking? It seems like the easy option, but it often leads to more problems down the track. Here’s why hiring dedicated bathroom caulking contractors like us makes a real difference:
Wrong materials
Most handymen use standard acrylic caulk. Acrylic is not waterproof enough for wet areas. It cracks, shrinks, and fails within weeks in showers. We use 100% neutralcure, sanitary-grade silicone, the only material rated for continuous wet exposure.
Skipping surface prep
The most common mistake is applying new silicone straight over the old, wet, mouldy joint. Without proper removal and drying, the new silicone simply can’t bond. It peels off within weeks.
No antifungal treatment
A general handyman won’t apply a mould inhibitor to the joint before sealing. We do, every single time.
No warranty
Our professional caulking services come with a workmanship warranty. You have peace of mind that if something doesn’t hold, we come back and fix it.
Victorian building standards
We comply with Australian wet-area sealing standards. Our work is done right for Victorian homes and conditions.

FAQs
Frequently Asked Questions
How long does shower caulking take to dry before I can use it?
We recommend waiting at least 24 to 48 hours before using the shower. This allows the sanitary silicone to fully cure and bond to the tiles, ensuring a durable, waterproof seal.
Can I just caulk over the old mouldy silicone in my shower?
No. This is a mistake that happens a lot. Old, mouldy, or moist silicone won’t stick to new silicone. It comes off quickly, and the seal breaks after a few days. The old stuff always has to come out first.
Do you do grout repair as well as caulking?
Yes, we handle the flexible caulking in corners and joints, but we can also assess and repair grout lines to ensure your entire tiled area is watertight and secure.
How much does a shower recaulk service cost in Melbourne?
The cost of a shower recaulk service depends on the size of your shower and the condition of the existing seals. We give you a clear, obligation-free quote before any work begins. No surprises.
How long will the new bathroom silicone last?
With our professional preparation and premium materials, your new silicone should last between 5 to 10 years, provided it is cleaned regularly and ventilated properly.
