If you have been thinking about installing laminate flooring in your home, you are in the right place. Laminate flooring is one of the most popular choices for homeowners today and for good reason. It looks great, lasts for years, costs far less than hardwood, and you can install it yourself without hiring a professional.
This guide walks you through every stage of laminate flooring installation, from measuring your room to fitting the final skirting board. Follow these steps carefully, and you will end up with a floor that looks professional and stays solid for years to come.
What Is Laminate Flooring and Why Is It a Smart Choice?
Laminate flooring is a multi-layer synthetic product designed to look like real wood or stone. Each plank has a high-density fibreboard core, a photographic layer that mimics wood grain, and a tough protective wear layer on top. The result is a floor that looks stunning but handles daily life far better than natural wood.
Here is why so many homeowners choose laminate flooring installation over other options:
- It costs significantly less than solid hardwood or engineered wood
- It resists scratches, stains, and fading better than most natural materials
- It installs quickly using a simple click-lock system, no glue or nails required
- It works over most existing subfloors including concrete, timber, and tile
- It is easy to clean and maintain with a damp mop
Most importantly, laying laminate wood flooring is a genuinely achievable DIY project. You do not need specialist skills or expensive equipment. You need patience, the right tools, and a step-by-step plan which is exactly what this guide gives you.
Things to Consider Before You Start
Before you buy a single pack of boards, take care of three important things: confirm laminate is the right choice for your space, calculate how much you need, and decide which direction to lay the planks.
Is Laminate Flooring Right for Your Room?
Laminate flooring works brilliantly in living rooms, bedrooms, hallways, dining rooms, and home offices. Standard laminate is moisture-resistant but not fully waterproof, so you need to be cautious in kitchens and avoid it entirely in wet rooms or bathrooms unless the product is specifically labelled as waterproof laminate.
Check the AC rating on the packaging before you buy. AC1 and AC2 suit low-traffic areas like bedrooms. AC3 works well in most domestic rooms. AC4 and AC5 are designed for heavy use and commercial spaces. Choose the right rating for your room and you will get many more years from your floor.
How Much Laminate Flooring Do You Need?
Measure the length and width of your room in metres. Multiply the two numbers together to get your total square meterage. Always add 10% on top of that figure to account for cuts and wastage. If you plan to lay the boards in a diagonal or herringbone pattern, add 15% instead.
For example, a room that measures 4 metres by 5 metres gives you 20 square metres. Add 10% and you need to buy at least 22 square metres of boards.
One important tip: buy all your packs from the same production batch. Check the batch number printed on the packaging. Boards from different batches can show slight colour variations that become very noticeable once laid side by side.
Which Direction Should You Lay the Boards?
Direction affects both the appearance and the feel of the finished room. Follow these simple rules:
- Lay boards parallel to the longest wall in the room, this makes the space feel larger and more open
- Lay boards towards the main light source, this reduces the visible shadow lines between planks
- In a hallway, always run boards lengthwise – this naturally draws the eye forward
- For a herringbone pattern, start from the centre of the room and work outwards
Tools and Materials You Will Need
Gather everything before you start. Stopping mid-installation to find a missing tool wastes time and risks misaligning rows.
Essential Tools List
- Tape measure and pencil
- Circular saw or mitre saw (for straight crosscuts)
- Jigsaw (for curved cuts around pipes and obstacles)
- Rubber mallet
- Tapping block (use an off-cut of laminate, never a bare hammer)
- Pull bar (for clicking boards tight against walls)
- Utility knife (for cutting underlay)
- Long spirit level or straightedge
- Combination square (for marking accurate 90-degree and 45-degree cuts)
- Safety glasses and dust mask
- Broom and vacuum cleaner
- Spacers or packer blocks (10mm–12mm)
Materials Checklist
- Laminate flooring packs (bought in the correct quantity with 10% added for waste)
- Underlay (see Step 4 for choosing the right type)
- Vapour barrier tape or self-adhesive underlay tape
- Damp-proof membrane (required for concrete subfloors)
- Skirting boards, scotia beading, or quadrant beading
- Threshold strips for doorways
Step 1: Acclimate Your Laminate Flooring
This is the step that most beginners skip, and skipping it causes real problems. Laminate flooring is manufactured in a controlled factory environment. Your home has a different temperature and humidity level. When you bring the boards inside and install them immediately, they will expand or contract after fitting. This leads to gaps opening up between boards, buckling, or persistent squeaking.
The solution is simple. Leave the unopened packs flat on the floor of the room where you plan to install them. Let them rest there for a minimum of 48 hours, 72 hours is better in older homes where temperatures vary more throughout the day.
Follow these guidelines during acclimatisation:
- Stack packs no more than three high
- Place small offcuts of wood between each pack so air can circulate freely around them
- Never lean packs against the wall — this causes them to warp
- If you have underfloor heating, keep it running at its normal temperature throughout the acclimatisation period
Once this waiting period is complete, your boards are ready to install.
Step 2: Prepare and Check Your Subfloor
The quality of your subfloor directly determines the quality of your finished floor. Laminate flooring is a floating floor, it sits on top of the subfloor without being glued or nailed down. This means any problems in the subfloor will eventually show through the finished surface.
How to Check for Levelness
Place a long spirit level or a straightedge across the floor in multiple directions. Laminate flooring can tolerate a maximum variation of 3mm over any 1.8 metre span. Any dip or ridge beyond this will cause boards to rock, click loose over time, or crack under pressure.
Fill dips with self-levelling floor compound and allow it to cure completely before you continue. Grind down or sand any high spots until they fall within the acceptable tolerance.
How to Check for Moisture
Moisture is the single biggest threat to any laminate flooring installation. Cut a one-metre square piece of polythene sheeting and tape all four edges firmly to the subfloor using duct tape. Leave it in place for 24 to 48 hours. When you lift it, check the underside. Any condensation or damp patches indicate excessive moisture in the subfloor.
For a more accurate test, use a professional moisture meter. Concrete subfloors must read 12% or below on a prong test. If your concrete fails this test, find and fix the source of moisture before you proceed with any flooring installation.
Preparing Concrete Subfloors
- Apply a damp-proof membrane if moisture levels are borderline
- Allow new concrete to cure for a minimum of 60 days before fitting any flooring
- Fill all cracks and holes with floor-levelling compound and allow it to dry fully
Preparing Timber and Wood Subfloors
- Screw down any squeaky or loose boards
- Ensure no nail heads or screws protrude above the surface level
- Sand down any edges that sit higher than the boards next to them
- Check for signs of rot or woodworm and treat the timber before you proceed
Laying Over Existing Tiles – Is It Possible?
Yes, you can install laminate flooring over existing tiles if they are all firmly fixed and level. Re-adhere or remove any loose tiles. Fill all grout lines that are deeper than 3mm with levelling compound to create a smooth surface for the laminate to rest on.
Step 3: Plan Your Layout
Spending 20 minutes planning your layout before you start saves hours of frustration during the actual installation. Two things matter most: calculating your row widths and setting up a straight reference line.
Calculating Your First and Last Row Width
Measure the total width of the room in millimetres. Divide this by the width of a single plank. The remainder tells you how wide your final row will be. If that final row comes out narrower than 50mm, it will be very difficult to fit neatly and will look awkward. In this case, trim your first row down so that both the first and last rows end up at a similar, balanced width.
For example, if your room is 3,800mm wide and each plank is 190mm wide: 3,800 divided by 190 equals 20 complete rows with no remainder. That is a perfect result. But if the calculation gives you a final row of only 30mm, cut your first row to around 115mm, this makes both the first and last rows roughly the same width.
Planning the Expansion Gap
Laminate flooring expands and contracts with changes in temperature and humidity throughout the year. You must leave an expansion gap of 10mm to 12mm around every fixed object in the room. This includes all walls, door frames, pipes, columns, and any built-in furniture.
Forgetting this gap or reducing it to save time, is the single most common cause of laminate floor failure. The boards have nowhere to expand in warm weather, so they push against the walls and buckle upwards. Always leave the full expansion gap.
Setting Up a Straight Reference Line
Walls are rarely perfectly straight. If you simply lay your first row against the wall, small deviations will compound across every subsequent row until the misalignment becomes clearly visible.
Fix this problem before you start. Drive a nail near each end of the starting wall. Measure out from the wall by exactly one plank width plus 12mm for the expansion gap. Tie a taut string line between the two nails. This gives you a perfectly straight reference line to work from, regardless of how straight or crooked the wall behind it is.
Step 4: Choose and Lay the Underlay
Underlay is not optional. Every single laminate flooring installation requires it, whether you are laying onto concrete or timber. It performs several essential functions that affect the comfort, sound level, and lifespan of your floor.
Why Underlay Is Not Optional
- It absorbs impact sound so footsteps are quieter, this matters significantly in flats and multi-storey homes
- It provides a layer of thermal insulation beneath the boards
- It compensates for minor subfloor imperfections up to 2mm in depth
- It creates a moisture barrier between the subfloor and the boards
- It makes the floor feel more comfortable and springy underfoot
Types of Underlay
Foam underlay is the most affordable option. It works well on concrete subfloors and usually comes with an integrated damp-proof membrane. It compresses easily and suits most standard laminate boards well.
Fibreboard underlay provides better thermal insulation and more effective levelling of minor imperfections. It works especially well on timber subfloors. If you use fibreboard on a concrete subfloor, lay a separate polythene damp-proof membrane beneath it.
Combination underlay includes both foam cushioning and a built-in moisture barrier in a single product. It is the most convenient choice for concrete subfloors and saves time during installation.
Acoustic underlay provides maximum sound reduction and is well worth the extra cost in flats or semi-detached homes where noise between floors and neighbouring properties is a concern.
Underlay for Underfloor Heating
If you have underfloor heating, choose an underlay with a low tog rating. The maximum recommended tog value for use with underfloor heating is 1.5 tog. Underlays with higher tog ratings act as insulators and significantly reduce the efficiency of your heating system.
How to Lay the Underlay Correctly
Roll out the underlay in the same direction you plan to lay the laminate boards. Push the first row tight against the starting wall. Butt each subsequent row tightly against the previous one without any overlap. Use vapour barrier tape to seal the joins between rows. Trim the edges with a utility knife so the underlay fits cleanly to the walls.
Never overlap the underlay at joins. Even a small overlap creates a ridge that boards will rock over, causing instability and noise.
Step 5: Lay the First Row
The first row is the foundation for everything that follows. Take your time here. Getting it straight and square sets up every subsequent row for success.
Place 10mm spacers against the starting wall along its entire length. Position your first board with the tongue side facing into the room and the groove side facing the wall. The tongue is the raised edge; the groove is the recessed edge. You always want to click subsequent rows onto the tongue, so face the tongue toward the room.
Place the second board end-to-end with the first. Click the short ends together by angling the board slightly and pressing it down flat. Continue along the full length of the wall. When you reach the end of the first row, measure the gap remaining and cut the final board to fit. Keep any off-cut longer than 300mm — use it to start your second row.
Cutting tip: Mark your cut line with a combination square and pencil. When using a hand saw or jigsaw, cut with the decorative face upward. When using a circular saw or mitre saw, cut with the decorative face downward. This keeps any chipping on the hidden side of the board.
Step 6: Lay the Remaining Rows
Hold the new board at a 20 to 30-degree angle. Insert the tongue into the groove of the previous row. Press the board downward and flat, it clicks into the locked position. Use a rubber mallet and tapping block to close any small gaps along the long edge. For end joints, use a pull bar hooked against the end of the board to draw it tight against the previous board.
Never strike a laminate board directly with a hammer. Always use a tapping block, an off-cut from one of your planks works perfectly. Direct hammer blows crush the edge of the click system and prevent boards from locking together properly.
How to Stagger the Joints
Stagger the end joints between rows by a minimum of 300mm — most experienced installers aim for 400mm or more. Staggering serves two purposes. It makes the floor structurally stronger by distributing load across different points. And it looks far more natural and professional. Aligned end joints create a grid-like pattern that looks cheap and mechanical.
Working with Multiple Open Boxes
Open several boxes at the same time and pick boards randomly from different boxes as you work. This mixes any slight colour variations across the floor rather than creating visible patches of lighter or darker planks in one area.
Fitting Around Doorframes and Obstacles
When you reach a doorframe, use a flush-cut saw to undercut the bottom of the architrave and door lining. Slide a piece of laminate underneath to check the gap. This allows the board to slide cleanly underneath the frame for a professional-looking finish without visible notch cuts.
For radiator pipes, mark the centre of the pipe on the board. Drill a hole 20mm larger than the pipe diameter to allow for expansion. Cut the board through the drilled hole, fit both pieces around the pipe, and glue the cut edge back together neatly.
Step 7: Cutting Laminate Boards to Fit
Accurate cutting separates a professional installation from an amateur one. Take exact measurements and mark them clearly with a pencil before every cut.
Straight Cross Cuts
Use a mitre saw for clean, fast, straight cuts across the width of a board. Clamp the board firmly, mark your line with a combination square, and cut just on the waste side of the pencil line.
Ripping Boards Lengthwise for the Final Row
Ripping means cutting along the full length of a board. You need this technique for the final row against the far wall. Measure the gap between the last fitted board and the wall. Subtract 10mm for the expansion gap. Mark this measurement along the full length of the board and cut it with a circular saw. Clamp the board securely to a pair of sawhorses to keep it completely stable.
Cutting Around Pipes, Pillars, and Curved Obstacles
For curved cuts around toilet bases, pillars, or built-in furniture, make a cardboard template first. Cut the template carefully and test the fit around the obstacle. Once satisfied, transfer the outline to the board and cut along the line with a jigsaw.
Step 8: Lay the Final Row
Use a pull bar to click the final row of boards into position. You cannot swing a mallet freely at the wall, so the pull bar is essential for this stage. Hook it against the end of the board and tap the other end to draw the board tightly into the locked position.
Before you finish, check that the expansion gap is consistent along the entire length of the final wall. The gap should measure between 10mm and 12mm throughout. Remove all spacers and packers from around the entire perimeter once the last board is in place. A forgotten spacer trapped under the skirting will prevent the floor from expanding freely and can cause buckling.
Common Laminate Flooring Installation Mistakes to Avoid
Even experienced DIYers make these mistakes. Knowing them in advance saves you time, money, and frustration.
Not acclimatising the boards. Boards installed straight from delivery will expand after fitting and push against the walls, causing buckling. Always wait the full 48 hours minimum.
Skipping the moisture check. Moisture trapped under laminate causes boards to swell, warp, and separate. Always test the subfloor before installing laminate flooring, especially on concrete.
Forgetting the expansion gap. This single mistake causes more laminate floor failures than anything else. Leave 10mm to 12mm around every fixed object without exception.
Not staggering the joints. Aligned joints weaken the floor structurally and look unprofessional. Offset end joints by at least 300mm between rows.
Using the wrong underlay. Underlay without a damp-proof membrane on a concrete subfloor allows moisture to attack the boards from below. Match the underlay to the subfloor type.
Fixing skirting boards to the floor. Nailing or gluing skirting to the laminate pins the floor down and prevents natural movement. Fix all skirting to the wall only.
Using a hammer directly on the boards. Direct hammer blows damage the click system. Always use a tapping block.
How to Maintain Your Laminate Floor After Installation
Laminate flooring is one of the easiest floor types to keep clean and in good condition. Follow these simple habits to protect your investment.
Sweep or vacuum regularly using a soft brush attachment. Hard bristles and beater bars scratch the surface over time. Wipe up spills immediately, laminate is moisture-resistant but not waterproof, and standing water will seep into the joints and cause swelling.
Use a damp, well-wrung mop for deeper cleaning. Never use a soaking wet mop. Avoid harsh chemical cleaners and use a pH-neutral laminate floor cleaner instead. Do not use steam mops on laminate, the intense heat and moisture will damage the core permanently.
Fit felt pads beneath all furniture legs to prevent scratching when chairs and tables move. Place a mat at external doorways to catch grit and moisture before it reaches the floor surface.
Frequently Asked Questions (FAQs)
How long does laminate flooring installation take?
An average room of around 15 square metres takes an experienced DIYer approximately 4 to 6 hours to complete, not including subfloor preparation. Add extra time for rooms with many obstacles or complex cuts.
Can I install laminate flooring in a bathroom or kitchen?
Standard laminate flooring is moisture-resistant but not fully waterproof. It handles occasional splashes but is unsuitable for areas with constant wet exposure. Several manufacturers produce waterproof laminate specifically designed for kitchens and bathrooms; always check the product specification before buying.
Does laminate flooring work with underfloor heating?
Yes. Most modern laminate boards are compatible with underfloor heating systems. Check the manufacturer’s guidelines for maximum temperature limits; most specify a maximum floor surface temperature of 27 degrees Celsius. Always choose an underlay with a tog rating of 1.5 or below to ensure the heating system works efficiently.
Can I lay laminate over existing laminate?
Technically yes, but it is rarely a good idea. Double-layering raises the floor height significantly, creates problems at door thresholds, and hides any moisture issues in the original floor. Remove the old floor wherever possible.
Why is my laminate floor squeaking?
Squeaking almost always comes from boards rubbing against each other or against an uneven subfloor. The most common causes are an uneven subfloor, missing underlay, an expansion gap that is too tight, or boards that were not fully clicked together during installation.
How do I fix gaps between boards?
Small gaps sometimes appear after installation due to seasonal temperature changes. If the boards are free-floating, gently tap them back together using a tapping block and rubber mallet. For persistent gaps, check whether something is blocking normal movement at the perimeter; a forgotten spacer or skirting boards fixed to the floor are the usual culprits.
Final Thoughts
Installing laminate flooring yourself is one of the most satisfying home improvement projects you can take on. The materials are accessible, the click-lock system is genuinely simple to work with, and the results transform a room completely.
The difference between a floor that lasts a decade and one that fails within a year always comes down to preparation. Check your subfloor. Acclimate your boards. Leave the expansion gaps. Choose the right underlay for your subfloor type. Follow these fundamentals carefully, and the rest of the laminate flooring installation process becomes straightforward and enjoyable.
Take your time with the first row, mix your boards from multiple boxes, and use the right tools for each cut. Your new floor will reward your patience every single day for years to come.
