Our Frequently Asked Questions
What is caulking and why does it matter in your home?
Caulking (also known as silicone sealing) is what keeps all those small gaps in your home properly sealed and protected. It involves applying flexible, waterproof silicone to joints around areas like bathrooms, kitchens, windows, and floors.
Good quality caulking in Melbourne homes is essential because it helps prevent water damage, stops mould growth, reduces drafts, and allows for natural movement in your surfaces. In short — it keeps your home looking better for longer and protects it from expensive repairs down the track.

Everyday Caulking Questions
What is caulking and why is it important?
Caulking is the process of sealing gaps, joints, and edges using flexible, waterproof silicone. It protects your home from water damage, mould growth, air leaks, and structural movement.
 Professional caulking is essential in bathrooms, kitchens, windows, balconies, and flooring areas. Proper sealing helps extend the life of your surfaces while keeping your home clean, dry, and well-protected.
How do I know if my silicone needs replacing?
If you’re noticing any of the following, it’s probably time for silicone replacement:
- Cracked, peeling, or shrinking sealant
- Black mould that keeps coming back
- Gaps around tiles, showers, or benchtops
- Water leaking or sitting where it shouldn’t
Old silicone doesn’t just look bad — it allows moisture to get behind surfaces, which can lead to hidden damage. Getting on top of it early can save you a lot of money.
Can you fix mouldy or black silicone?
Absolutely. We specialise in removing mouldy silicone and replacing it properly.
Once mould gets into silicone, cleaning it is usually just a short-term fix. The best long-term solution is to fully remove the old sealant and replace it with fresh, mould-resistant silicone so your space is clean, hygienic, and protected again.
How long does silicone caulking last?
Most professional silicone caulking lasts anywhere from 5 to 10 years, depending on things like:
- How much moisture the area gets
- Ventilation (especially in bathrooms)
- Cleaning habits
- Quality of the original installation
High-use areas like showers and bathrooms may need resealing sooner — especially in busy Melbourne households.
Do you remove old silicone before applying new sealant?
Yes — and this is a big one.
Proper professional caulking in Melbourne always includes removing the old silicone first. Applying new sealant over the top might seem quicker, but it won’t bond properly and won’t last.
We make sure everything is cleaned, prepped, and done properly so you get a clean finish that actually holds up.
How long does caulking take to dry?
Most silicone sealants:
- Form a surface skin within 30–60 minutes
- Fully cure within 24 hours
For best results, we recommend keeping the area dry during that curing time — especially in showers and wet areas.
What areas of the home need caulking?
You’d be surprised how many places rely on good sealing. Common areas include:
- Bathrooms (showers, baths, vanities, tiles)
- Kitchens (benchtops, sinks, splashbacks)
- Windows and doors
- Skirting boards and flooring
- Balconies and outdoor joints
We provide full-house caulking services across Melbourne, for both residential and commercial properties.
How much does caulking cost in Melbourne?
The cost of caulking services in Melbourne depends on the size and condition of the job, but as a guide:
- Shower resealing: from $250
- Full bathroom reseal: from $400
- Kitchen caulking: from $250
- Window caulking (full house): from $950
We’re happy to provide fixed quotes based on photos or an on-site visit — no surprises.
Is professional caulking worth it?
Short answer: yes.
Professional caulking gives you:
- Clean, straight lines (no messy DIY jobs)
- Proper surface prep so it actually lasts
- High-quality, mould-resistant materials
- A finish that looks sharp and holds up over time
DIY can work… but more often than not, it ends up needing to be redone sooner rather than later.

Why Fresh Caulking Makes a Big Difference
Instantly refresh the look of your home
Old silicone can quickly make a space feel tired. It often becomes:
- Yellowed
- Cracked
- Mouldy
- Uneven
Fresh caulking creates clean, crisp lines that instantly lift the look of your bathroom or kitchen — it’s one of the easiest ways to make a space feel new again.
How soon can I use my shower after resealing?
We recommend waiting at least 24 hours before using your shower after resealing. This gives the silicone time to fully cure and bond properly — which is key to getting a long-lasting result.
Does it Extend the Life of Your Surfaces
Good silicone sealing helps protect:
- Tiles and grout
- Benchtops
- Flooring
- Windows and frames
By keeping moisture out and allowing for movement, it helps prevent damage and reduces the need for costly repairs later.
Increase Property Value and Buyer Appeal
If you’re selling or renting in Melbourne, details matter.
