2. Room Conditions & Planning Ahead
Taking a little time to prepare the room and plan ahead will make installation smoother and help ensure the herringbone pattern remains accurate throughout the floor.
Room Conditions
Click LVT (SPC) herringbone flooring should be installed in a dry, enclosed space under normal living conditions. Aim to keep the room at a stable, comfortable temperature, ideally between 18°C and 27°C, both before and during installation.
Avoid installing the floor in areas where temperatures fluctuate significantly or where the room is not yet fully weather-tight, as stability is especially important for herringbone patterns. Installation should only take place once all wet trades are complete.
Subfloor Overview
Click LVT (SPC) herringbone flooring can be installed over most common subfloors, including concrete and wooden subfloors, provided they are stable and suitable for a floating floor.
Any existing floor coverings should be removed before installation, leaving a solid base for the new floor. Further guidance on preparing the subfloor is covered later in this guide.
Measuring the Room
Measure the length and width of the room to calculate the total square metres required. Take measurements at several points, particularly in older or irregularly shaped rooms, and use the largest measurement to ensure accurate coverage.
Ordering the Correct Quantity
When ordering your Click LVT (SPC) herringbone flooring, allow an additional 10–15% for cutting, waste, and pattern layout. Herringbone installations typically require a little more cutting than straight-plank floors, so this allowance helps ensure you can complete the installation without interruption.
Important: It is the installer’s responsibility to inspect the flooring prior to installation. Installation of the product confirms that the material has been checked and accepted.
3. Acclimatising Click LVT (SPC) Herringbone Flooring
Before installation, allow your Click LVT (SPC) herringbone flooring to acclimatise in the room where it will be fitted for 24–48 hours. This allows the planks to adjust to the ambient conditions and supports a smooth, consistent installation.
Keep the packs flat and stored on a level surface, away from direct heat sources or strong sunlight. The room should be maintained at normal living conditions, with a stable temperature and no extreme changes during this period.
If the room has underfloor heating, ensure the system is switched off during acclimatisation and installation. Full guidance on using underfloor heating with SPC flooring is provided later in this guide.
4. Preparing the Subfloor
Click LVT (SPC) herringbone flooring performs best when installed over a clean, dry, flat, and stable base. Because herringbone patterns rely on precise alignment, subfloor preparation is especially important to achieve a clean, accurate finish.
Clean & Dry
The subfloor should be free from dust, debris, paint, old adhesive residue, or loose material. Sweep and vacuum thoroughly before installation. Any spills or damp patches should be fully dry before the flooring is laid.
Flatness Tolerance
The subfloor must be level to within 3mm over a 2-metre straight edge. This tolerance is particularly important for herringbone installations, as even small uneven areas can affect joint alignment and cause the pattern to drift.
High spots or dips beyond this tolerance should be corrected before installation to ensure the planks sit evenly and the click system engages properly.
Moisture Awareness
Concrete subfloors should be dry and suitable for a floating floor installation. Where moisture levels are elevated, a suitable surface damp-proof membrane should be installed in accordance with manufacturer guidance. Wooden subfloors should be sound, securely fixed, and free from movement.
Existing Floor Removal
Remove any existing floor coverings, trims, or fixings before installation. Ensure nails or screws are set below the surface so they do not interfere with the underlay or plank connections.
Built-in Underlay
Click LVT (SPC) herringbone flooring is supplied with a built-in underlay, designed to provide comfort and acoustic performance. No additional underlay should be installed unless specifically approved for use with the product.
For more detailed guidance on subfloor levelling, moisture testing, and preparation standards, see our full Subfloor Preparation Guide.
5. Planning the Herringbone Layout
Herringbone flooring relies on symmetry and alignment, so taking time to plan the layout before installation begins is essential for achieving a clean, balanced finish.
A & B Planks Explained
Click LVT (SPC) herringbone flooring is supplied with two plank types, commonly labelled “A” planks and “B” planks. These are mirror-image pieces designed to lock together correctly and form the herringbone pattern.
This configuration is common in parquet and herringbone flooring and ensures joints align consistently throughout the installation. Both plank types are used together and must be installed in the correct sequence to maintain the pattern.
Before starting, open several boxes and make sure you have a mix of both A and B planks available. The plank type is clearly marked on the back of each board or on the packaging. Keeping both types to hand as you work helps the installation flow smoothly and avoids interrupting the pattern mid-row.
Pattern Orientation
Decide which direction you want the herringbone pattern to run. In most rooms, the pattern works best aligned with the longest dimension of the room or the main visual axis when entering the space, helping the layout feel balanced and intentional.
Centre Line & Reference Lines
Herringbone installation always starts from a central reference line rather than from a wall.
- Measure the width of the room and mark the centre point
- Snap or draw a straight centre line along the length of the room
- This line will be used to align the starter pattern
Check that the centre line is square to the room before you begin building the pattern. This can be done using a 3-4-5 method or by measuring diagonals to confirm accuracy.
Walls are rarely perfectly straight, so relying on a centre line helps prevent the pattern from drifting as the floor is built out.
Dry Laying the Starter Pattern
Before clicking any planks together, dry-lay a small section of the herringbone pattern along the centre line. This allows you to:
- Confirm the pattern orientation
- Check alignment against the reference line
- Make small adjustments before committing
Spending a few minutes on this step helps the pattern stay true across the room and avoids corrections later in the installation.
6. Installing Your Click LVT (SPC) Herringbone Floor – Step by Step
The steps below apply specifically to Click LVT (SPC) herringbone installations. For straight-plank SPC installation, see our Click LVT (SPC) Plank Flooring Installation Guide.
7. Expansion & Movement Rules
Click LVT (SPC) herringbone flooring is installed as a floating floor, which means it needs a small amount of space to move as a complete surface. Allowing for this movement during installation helps the floor perform correctly over time and keeps joints looking clean and aligned.
Perimeter Gaps
Leave a consistent 6mm expansion gap around the entire perimeter of the room. This gap should be maintained between the flooring and all walls, skirting boards, and vertical surfaces. Use spacers during installation and remove them once the floor is complete.
Fixed Objects
A 6mm expansion gap should also be left around all fixed objects, including:
- Kitchen units and fitted furniture
- Radiator pipes
- Structural columns
- Door frames and thresholds
The flooring should never be tight against any fixed element.
Kitchen Cabinets & Islands
Click LVT (SPC) flooring should not be installed underneath heavy kitchen cabinets or islands. These items should be fitted first, with the flooring installed around them and the correct expansion gap maintained.
Kitchen units and islands typically use plinths, which can be used to neatly cover the flooring edge while still allowing the floor to move freely.
Installing heavy, fixed furniture on top of a floating floor can restrict movement and may lead to stress or distortion over time.
Doorways
Expansion gaps must be allowed at doorways and openings between rooms. Where the same Click LVT (SPC) flooring is installed continuously between adjoining rooms, the floor can often run through without a transition, provided it is free to move as a single floating surface.
Threshold or transition profiles should be used where required to maintain expansion gaps, accommodate movement, or where different flooring types meet.
Large Rooms & Long Runs
Click LVT (SPC) herringbone flooring can usually be installed as one continuous floor across multiple rooms or long runs, provided expansion gaps are maintained and the floor is not restricted by fixed objects.
Where the floor extends beyond approximately 10 metres in one direction, approaches or exceeds approximately 100m², or movement may be restricted, a transition profile can be used to divide the floor into smaller sections, each with its own expansion allowance.
Transitions
Use appropriate transition profiles where the SPC flooring meets:
- Other flooring types
- Separate rooms
- Changes in direction
Transitions help accommodate movement while creating a clean, finished appearance.
8. Underfloor Heating Compatibility
Click LVT (SPC) herringbone flooring works very well with water-based underfloor heating systems when installed and operated correctly. These systems provide slow, even heat, which suits floating SPC floors and helps maintain consistent performance across the surface.
Water-Based Underfloor Heating
Water-based (hydronic) underfloor heating systems are the preferred option for Click LVT (SPC) herringbone flooring. When installed within the subfloor and controlled accurately, they offer stable heat distribution and reliable day-to-day use.
The maximum finished floor surface temperature should not exceed 27°C. To allow conditions to stabilise, the heating system should be switched off at least 48 hours before installation. After installation, the system can be switched back on gradually, increasing the temperature by no more than 5°C per day until normal operating levels are reached.
The system should be fully commissioned and pressure-tested before flooring installation begins.
Electric Underfloor Heating
Some electric underfloor heating systems may be suitable for use beneath Click LVT (SPC) herringbone flooring when they are fully embedded within the subfloor and provide accurate temperature control. Because electric systems can vary widely in design and performance, compatibility should be confirmed with the underfloor heating manufacturer and the flooring supplier before installation.
This approach helps ensure temperatures remain consistent across the floor surface and supports long-term performance.
Why Temperature Control Matters
Maintaining stable temperatures allows the flooring system to expand and contract evenly as a single floating surface. This helps keep joints aligned, prevents localised stress, and ensures the floor continues to look and perform as intended.
For more detailed guidance on system setup, commissioning, and temperature control, see our dedicated guide: LVT Click (SPC) Flooring & Underfloor Heating Guide.
9. Finishing Details
Once the main floor is installed, a few finishing touches will help achieve a clean, professional result and allow the floor to perform as intended.
Fitting Around Pipes
Where pipes pass through the floor, mark their positions carefully on the plank. Drill a hole slightly larger than the pipe to allow for expansion. The plank can then be cut to the hole and fitted into place.
If needed, a small offcut can be glued back in position behind the pipe to create a neat finish. Pipe covers can also be used to conceal the expansion gap.
Door Frames
For a tidy result at doorways, the bottom of the door frame or architrave can be undercut so the flooring slides neatly underneath. This allows the floor to move freely while avoiding visible gaps.
When working around door frames, take your time and test-fit planks before locking them fully into place.
Transitions
Transition profiles are used where the SPC flooring meets other floor types, changes direction, or passes through doorways where an expansion gap needs to be covered. The profile should sit above the floor without restricting movement.
Skirting Boards & Trims
Skirting boards, beading, or edge trims are used to cover the expansion gap around the perimeter of the room. These should be fixed to the wall, not the floor, allowing the Click LVT (SPC) herringbone flooring to move freely underneath.
Trims should be colour-matched to the skirting or wall finish, rather than the flooring itself. These profiles are designed to blend into the skirting line, creating a clean transition without drawing attention to the edge of the floor.
Spare Planks
It’s a good idea to keep a few spare planks once installation is complete. These can be useful for future repairs or replacements and are best stored flat in a dry area.
10. Final Checks & After Installation Care
Once installation is complete, remove all spacers from around the perimeter of the room and check that the floor surface sits flat and even. Visually inspect the joints to confirm they are fully engaged, aligned, and level before fitting skirting boards or trims.
Give the floor a light clean using a soft brush or vacuum to remove any dust from installation. Avoid using excess moisture at this stage.
Furniture can be returned once installation is complete, provided items are lifted into position rather than dragged. Dragging heavy furniture can stress joints and damage the surface of the floor.
For ongoing care, regular sweeping or vacuuming will help keep the floor looking its best. Using felt pads under furniture and placing mats at entrances will help reduce everyday wear and protect the locking system.
For full cleaning advice and long-term care recommendations, see our dedicated guide: LVT & SPC Flooring Care & Maintenance Guide.
11. Installation FAQs – Click LVT (SPC) Herringbone Flooring
These FAQs address the most common technical issues that affect Click LVT (SPC) installations, particularly those relating to subfloor preparation, movement allowance, and joint engagement.
Herringbone SPC installation is typically more demanding than straight-plank click flooring because the pattern relies on accurate set-out and early-row control. Minor alignment errors can compound as the layout expands across the room.
Once the centre line is established correctly and the starter section is stable and fully locked, the click-lock system allows the floor to build consistently with controlled, methodical installation.
Herringbone layouts should be set out from a central reference line rather than from a wall. Walls are rarely perfectly straight, and working from a perimeter edge increases the risk of cumulative drift and uneven border finishes.
A central set-out keeps the pattern balanced and visually consistent as it progresses towards both sides of the room.
The subfloor must be flat to within 3mm over a 2-metre straight edge. This tolerance is particularly important for herringbone layouts due to the number of joints and the way the zig-zag points align.
Dips and high spots can affect joint engagement, create uneven angles, and lead to visible pattern distortion. Subfloor preparation is therefore more critical for herringbone installations than for straight-plank systems.
Herringbone SPC systems use two mirror-image planks (A and B) designed to lock together in an alternating sequence to form the correct pattern geometry.
Incorrect sequencing can prevent joints from engaging properly and will disrupt alignment as the installation progresses. Plank types should be identified and kept organised before starting the set-out.
Continuous installation between rooms is possible where the floor can move freely as a single floating surface and expansion allowances are maintained throughout.
Transition profiles are often recommended where:
- The floor passes through doorways or narrow openings
- The run becomes long (around 10 metres or more)
- The total area approaches or exceeds roughly 100m²
- Fixed furniture or tight thresholds may restrict movement
Where movement restriction is likely, incorporating a discreet transition profile reduces the risk of joint stress or pattern distortion.
Herringbone SPC flooring is compatible with underfloor heating systems when temperature limits are controlled. The finished floor surface temperature must not exceed 27°C.
The heating system should be switched off at least 48 hours before installation, remain off during fitting, and then be recommissioned gradually after installation. This reduces the risk of uneven thermal movement across the floating floor.
Pattern drift should be corrected as early as possible. Herringbone layouts visually magnify minor inaccuracies, and continued installation can compound the deviation across the room.
The affected area should be lifted back to the last correctly aligned section, checked against the centre reference line, and rebuilt before progressing. Ongoing checks with a straight edge and regular visual sight lines help maintain alignment.
