You’ve picked a beautiful new floor, and then your installer asks: scotia, or do you want the skirting off? It sounds like a small detail, but the trim you choose is the difference between a floor that looks built in and one that looks added later. Here’s what scotia, quad and skirting actually are, the pros and cons of each, and what they cost in Melbourne.
What Scotia Is and Why Floating Floors Need It
Scotia is a small trim moulding that sits along the bottom of your skirting boards, covering the gap between the wall and the edge of a new floor.
Floating floors, like hybrid, laminate and many engineered timber floors, need a gap at every wall so they can expand and contract with temperature and humidity. If your skirting boards stay where they are, that gap is visible. Scotia covers it.
Scotia’s profile is concave, meaning it curves inward like a small cove. It’s one of the most common flooring trims in Australia because it’s quick, cheap and doesn’t disturb the walls.
Scotia vs Quad vs Skirting: The Difference in One Table
| Scotia | Quad | Skirting | |
|---|---|---|---|
| Shape | Concave curve | Quarter round, convex curve | Tall flat or profiled board |
| Where it goes | Along the bottom of existing skirting | Along the bottom of existing skirting | On the wall, sitting on the finished floor |
| Covers expansion gap | Yes | Yes | Yes, if fitted after the floor |
| Look | Subtle and traditional | Slightly bulkier, rounder | Cleanest, most built in look |
| Disturbs walls | No | No | Yes, removal or new install |
| Relative cost | Lowest | Low | Highest |
| Best for | Budget jobs, keeping good skirting | Older homes, slightly bigger gaps | New builds, full renos, premium finish |
Why the Expansion Gap Exists and Why You Can’t Just Fill It
Every floating floor moves. In a hot, humid Melbourne summer it expands. In a dry, heated winter it shrinks, which is why gaps appear between boards in winter. The expansion gap, usually around 8mm to 10mm depending on the brand, gives it room to move.
What happens if you fill or pin the gap?
- The floor pushes against the walls when it expands
- Boards peak or lift at the joints
- Click joints break and gaps appear
- Your warranty is likely void
That’s why you can’t just fill the gap with silicone or gap filler, or fix the trim down into the floor. The trim must cover the gap while still letting the floor move underneath it.
Option 1: Remove and Refit the Existing Skirting
The existing skirting boards are carefully removed, the floor is installed with its expansion gap, and the same skirting is fixed back on, sitting on top of the new floor.
Pros:
- Clean, built in look with no extra moulding
- Keeps your original skirting, which suits period homes
Cons:
- Old skirting can crack or split when removed
- Walls usually need filling and touch ups
- Skirting needs repainting after refitting
- Costs more than scotia
Best for: period and Victorian homes with good quality or heritage skirting you want to keep.
Option 2: Install New Skirting Over the Finished Floor
The old skirting is removed and new skirting is installed after the floor goes down. This is standard practice in new builds.
Pros:
- The cleanest, most modern finish
- A chance to upgrade to taller skirting, which looks great with wide plank floors
- No risk of damaging old boards you care about
Cons:
- The most expensive option
- Needs painting, often by a separate trade
- Takes longer to finish
Best for: full renovations, new builds, and anyone wanting a premium result.
Option 3: Keep the Skirting and Add Scotia or Quad
The skirting stays exactly where it is. The floor goes down with its expansion gap, and scotia or quad is fixed to the bottom of the skirting to cover it.
Pros:
- Quickest and cheapest option
- No damage to walls or skirting
- Colour matched options available
Cons:
- Adds a visible extra moulding line
- Can look like an add on, especially in modern homes
- Collects dust along the top edge
Best for: rentals, budget renovations, and homes where the skirting is in good shape and hard to remove.
Which Option Looks Best, and Why Many Builders Now Avoid Scotia
For looks, the ranking is usually:
- New skirting fitted over the floor, the cleanest finish
- Refitted original skirting, clean and authentic
- Scotia or quad, practical but visible
Many builders and designers now avoid scotia in new homes and higher end renovations because the extra moulding breaks the clean line between wall and floor. It can look dated, especially with modern square edged skirting.
That said, scotia is still a perfectly good choice in plenty of homes. A well fitted, colour matched scotia with neat mitres looks tidy, and it saves time and money.
Choose the floor first, then the trim that suits it:
- waterproof hybrid with colour matched scotia
- 12mm laminate and its matching trims
- European Oak boards for wide plank looks
- transition strips where floors meet at doorways
- stair nosings to finish your treads
Matching Trim Colour to Hybrid, Laminate and Timber Floors
You’ve got three main approaches:
| Approach | How it looks | Best for |
|---|---|---|
| Match the floor | Trim blends into the floor, so the floor looks like it runs to the wall | Hybrid and laminate floors with colour matched scotia |
| Match the skirting | Trim blends into the skirting, so it reads as part of the wall | White or painted skirting, most modern homes |
| Contrast | Trim stands out as a feature | Rarely recommended, as it highlights the moulding |
Our usual advice: if your skirting is white, paint the scotia white too, so it disappears into the skirting. If you want the trim to match the floor, use a colour matched scotia from the same range — our guide to light and dark floor tones can help you judge how visible it will be.
Sizes, Lengths and How Much You Need
Scotia and quad come in a range of sizes to cover different gaps. Choose a size that comfortably covers your expansion gap plus a little overlap onto the floor.
How to work out how much you need:
- Measure the perimeter of each room, meaning the total length of all walls
- Subtract door openings
- Add about 10% for cutting and mitres
- Divide by the length of each piece to work out how many lengths to order
Example: a 4m x 5m bedroom has an 18m perimeter. Take off a 0.8m doorway, leaving 17.2m. Add 10% and you need about 19m of scotia.

How Scotia Is Fitted: Mitres, Adhesive, and Why It Fixes to the Skirting Not the Floor
A neat scotia job comes down to a few details:
- Fix it to the skirting, never the floor. Scotia is glued or pinned to the skirting board so the floor can still move underneath.
- Leave it resting lightly on the floor. It should touch the floor surface without pressing down.
- Mitre the corners. Internal and external corners are cut at matching angles for a tight join.
- Use neat end returns. Where scotia meets a door frame or ends mid wall, the end is shaped or returned rather than left open.
- Fill and paint if needed. Painted scotia gets its nail holes filled and joins caulked for a seamless look.

Frequently Asked Questions
What is scotia in flooring?
A small concave moulding fixed to the bottom of the skirting to cover the expansion gap around a floating floor.
What’s the difference between scotia and quad?
Scotia curves inward, while quad is a rounded quarter circle that curves outward. Both do the same job.
Do you need scotia for hybrid flooring?
Only if you keep your existing skirting. If skirting is removed and refitted or replaced, you don’t need scotia.
What is an alternative to scotia beading?
Removing and refitting your skirting, or installing new skirting after the floor goes down.
What colour should scotia be?
Usually white or the same colour as your skirting, so it blends in. Colour matched scotia can also blend with the floor.
Should scotia be nailed to the floor?
No. It should be fixed to the skirting only, so the floating floor can move freely.
Can I use silicone instead of scotia?
No. Silicone pins the floor and doesn’t allow it to move, which can cause lifting and gaps.
How much scotia do I need?
Measure the room perimeter, subtract doorways and add about 10% for cuts.
Is scotia old fashioned?
Many modern homes avoid it for a cleaner look, but neat, painted scotia still looks tidy and saves money.
