Homeowner’s Guide to Caulking in Melbourne
Not Sure If Your Home Needs Caulking? Start Here.
Caulking isn’t just for new builds or renovations — it’s essential maintenance. Done right, it protects your home from moisture, mould, pests, noise, and rising energy costs.
But most Melbourne homeowners don’t know when (or where) to re-caulk — or what products to even use.
Here’s a no-BS guide to caulking your Melbourne home like a pro — or better yet, calling one.
What Is Caulking, Really?
Caulking is the process of sealing joints, gaps, and cracks in your home using flexible materials like silicone or polyurethane. The goal? Keep air, water, dust, and insects out.
When Should You Caulk?
Here are the signs it’s time:
You feel draughts near windows or doors
You spot cracks or gaps along baseboards or walls
There’s mould or mildew forming near showers, sinks, or windows
Paint is peeling around joints or trim
Your home feels cold in winter or too hot in summer, even with heating/cooling on
👉 Rule of thumb: Inspect annually, and plan to re-caulk every 5–10 years depending on exposure and material quality.
Where Should You Caulk?
Interior areas:
Bathrooms (showers, tubs, vanities)
Kitchens (sinks, splashbacks)
Laundry rooms
Skirting boards
Window & door frames
Exterior areas:
Around windows and doors
Gaps in brickwork or cladding
Expansion joints
Around utility penetrations (gas, water, electrical)
What Caulk Should You Use?
Silicone Sealant
Best for wet areas & exterior use
Flexible, waterproof, UV-resistant
Not paintable
Acrylic Caulk
Best for interior gaps
Paintable, easy to clean up
Less flexible than silicone
For Melbourne’s wild weather, we recommend UV-stable silicone for outdoors and premium acrylic for indoor cosmetic joints.
