How to Fit Laminate Flooring: Complete Step-by-Step Guide

Learning how to fit laminate flooring is one of the most rewarding DIY projects you can tackle. Unlike hardwood or tile, laminate uses a click-lock system that requires no glue, no nails, and no special skills — just patience, the right tools, and a solid understanding of the process. Most homeowners can fit a standard room in a single weekend.

This guide walks you through every step of the process, from preparing your subfloor to cutting around door frames and pipes, handling expansion gaps, and finishing with transitions. Whether this is your first flooring project or you have done it before, this resource covers the details that separate a professional-looking result from a sloppy one.

Tools and Materials You Need

Before you start fitting laminate flooring, gather everything you need so you are not making trips to the hardware store mid-project. Here is the complete list.

Essential Tools

• Tape measure — for measuring rooms, planks, and cuts
• Pencil — for marking cut lines on planks
• Speed square or T-square — for marking straight crosscuts
• Jigsaw or circular saw — for cutting planks to length
• Mitre saw (optional) — makes faster, cleaner crosscuts
• Oscillating multi-tool — essential for undercutting door frames
• Pull bar — for pulling the last plank in each row tight
• Tapping block — for tapping planks together without damaging edges
• Rubber mallet — used with the tapping block
• Spacers — 8-10mm spacers for maintaining expansion gaps
• Utility knife — for cutting underlay and trimming
• Knee pads — you will be on your knees for hours

Materials

• Laminate flooring — order 10% extra for cuts and waste
• Underlay — foam or combination underlay with built-in vapour barrier
• Vapour barrier — if your underlay does not include one (essential over concrete subfloors)
• Transition strips — T-bars, reducers, or threshold strips as needed
• Beading or scotia — to cover expansion gaps at walls
• Pipe covers — radiator pipe collars for a clean finish

Preparing the Room and Subfloor

Proper preparation is the most important part of learning how to fit laminate flooring. Rushing this step leads to squeaky floors, visible gaps, and premature damage.

Acclimate the Laminate

Bring the laminate boxes into the room where they will be installed at least 48 hours before fitting. Lay them flat (not on their sides) and leave them unopened. This allows the boards to adjust to the room’s temperature and humidity, which prevents expansion or contraction after installation.

Remove Existing Flooring and Skirting

Remove any old carpet, vinyl, or loose flooring material. If fitting over existing hard flooring (tile or vinyl in good condition), you may be able to lay directly on top — but only if the surface is flat, firmly bonded, and does not raise your floor height past acceptable limits for door clearance.

Remove skirting boards carefully using a pry bar and utility knife. Label the back of each piece to make reinstallation easier. If you prefer not to remove skirting, you can use scotia or beading to cover the expansion gap instead.

Check the Subfloor

The subfloor must be flat, dry, clean, and structurally sound. Use a long straight edge or spirit level to check for dips and bumps. The general rule is that the subfloor should be flat within 3mm over a 1-metre span.

• Concrete subfloors: Fill low spots with self-levelling compound. Grind down high spots. Test moisture levels — a concrete slab above 75% relative humidity needs a vapour barrier.
• Wooden subfloors: Screw down loose boards to eliminate squeaks. Sand or plane down high spots. Replace any damaged or rotten boards.
• Existing tile or vinyl: Fill grout lines if laying over tile. Ensure vinyl is well-bonded with no bubbles or loose edges.

Laying the Underlay

Underlay serves three functions: it smooths out minor subfloor imperfections, provides sound insulation, and acts as a moisture barrier (if it includes a built-in vapour layer).

Roll out the underlay parallel to the direction you plan to lay the laminate. Butt the edges together without overlapping — overlapping foam underlay creates a bump that will be visible through the laminate. Tape the seams with underlay tape to hold everything in place.

If using a separate vapour barrier (required over concrete), lay that first. Overlap the sheets by 200mm and tape the seams. The vapour barrier should run up the walls by 50mm — you will trim it after fitting.

Only lay enough underlay for the section you are currently working on. This prevents the underlay from getting dirty, damaged, or shifted before the laminate goes down.

Starting the First Row

The first row sets the foundation for the entire floor. Take your time here because any errors compound as you work across the room.

Choose Your Direction

Laminate typically looks best when laid lengthwise in the direction of the longest wall or toward the main light source. Running planks toward a window makes the room feel longer and minimizes the visibility of seams.

Measure and Plan

Measure the width of the room and divide by the width of a plank. If the last row would be less than 50mm wide, rip the first row narrower to balance both sides. A sliver of laminate at the far wall looks unprofessional and is difficult to fit.

Cut the Tongue Off the First Row

The first row sits against the wall. Cut or snap off the tongue side (the protruding edge) so the plank sits flush against your spacers. Use a table saw, circular saw, or jigsaw for a clean cut.

Place Spacers and Start

Place 8-10mm spacers along the starting wall. These create the expansion gap that laminate needs to move with temperature and humidity changes. Lay your first plank in the left corner (if you are right-handed) with the cut edge against the spacers.

Connect the next plank by angling its short end into the previous plank’s end joint and pressing down until it clicks flat. Continue across the row. Cut the last plank to fit, leaving an expansion gap at the far wall. If the offcut is at least 300mm long, use it to start the next row.

Clicking Planks Together

Modern laminate uses click-lock profiles that snap together without glue. The two most common systems are angle-click and drop-lock.

Angle-Click Method

Hold the new plank at roughly a 20-30 degree angle, insert the tongue into the groove of the previous row, and press down while pushing forward. The plank should click flat. This is the most common system and the easiest to work with.

Drop-Lock Method

Align the plank directly above its position, engage the long edge, and press straight down until it clicks. This system is common in higher-end laminate brands.

Tips for Clean Connections

• Always connect the long side first, then the short end
• Use a tapping block and rubber mallet to close stubborn joints — never hit the laminate directly
• If a plank will not click in, check for debris in the groove or a damaged tongue
• Stagger end joints by at least 300mm (ideally 500mm) between adjacent rows for structural stability and a natural look

Expansion Gaps Explained

Expansion gaps are non-negotiable when you fit laminate flooring. Laminate is a floating floor — it sits on top of the subfloor without being attached to it. As temperature and humidity change, the entire floor expands and contracts. Without gaps, the floor buckles, peaks, or lifts at the edges.

How Big Should the Gap Be?

Most manufacturers require an 8-10mm expansion gap around all walls, fixed objects (kitchen islands, columns, pipes), and transitions between rooms. Check your specific product’s installation instructions, as some require up to 12mm.

Where Do You Need Gaps?

• Around every wall perimeter
• Around door frames (even after undercutting)
• Around pipes and radiator standpipes
• At transitions between rooms
• Around kitchen islands and built-in cabinets
• At any fixed vertical object that the floor meets

Never pin the floor down with screws, nails, heavy furniture legs on hard pads, or by wedging it under a fixed object. The floor must be free to float in every direction.

Cutting Around Door Frames

Door frames are the trickiest part of fitting laminate, but the technique is straightforward once you understand it. The laminate slides underneath the door frame rather than being cut to fit around it.

Step-by-Step Door Frame Method

1. Place a piece of laminate and underlay next to the door frame to use as a height guide
2. Mark the cut height on the door frame using the top of the laminate and underlay as your reference line
3. Use an oscillating multi-tool (or hand saw) to cut the architrave and door frame at the marked height
4. Remove the cut-off piece and vacuum out the dust and debris
5. Slide the laminate plank underneath the door frame — it should slip in cleanly with the expansion gap hidden behind the frame

This method gives a far cleaner result than trying to cut the laminate to match the profile of the door frame. It also hides the expansion gap completely.

What About the Door Itself?

The new floor height (laminate plus underlay) is typically 10-14mm. If your door clears, no trimming is needed. If it drags, remove the door and trim the bottom with a circular saw using a straight-edge guide. Many installers do this before starting so the door is out of the way.

Fitting Around Pipes and Obstacles

Radiator pipes, toilet flanges, and other vertical obstructions need a clean cutout. Here is the method.

1. Measure the pipe position — mark the centre of the pipe on the plank, both the distance from the wall and the distance from the previous plank
2. Drill a hole using a hole saw or spade bit that is 20mm wider than the pipe diameter (to account for the expansion gap on each side)
3. Cut a straight line from the hole to the nearest edge of the plank (usually the back edge closest to the wall)
4. Fit the plank around the pipe and glue the cut-off piece back in place with wood glue
5. Cover with pipe collars — these snap-on covers hide the gap around the pipe for a clean finish

Working in Tight Spaces

Tight spaces — under radiators, inside closets, behind toilets — make clicking planks together difficult or impossible. Here are the solutions.

Under Radiators

If you cannot angle-click under a radiator, cut off the bottom lip of the groove using a sharp utility knife. Apply a thin bead of PVA wood glue to the tongue, slide the plank flat into position, and weight it down until the glue sets. This is called a “glue and slide” method.

In Closets and Small Rooms

Pre-assemble several planks outside the closet and slide the entire section in as one piece. Use a pull bar and tapping block to close joints against far walls where you cannot swing a mallet.

Last Plank in a Row Against a Wall

A pull bar is essential here. Hook the pull bar over the end of the plank and tap the other end of the bar with a hammer to draw the plank tight against the previous plank.

Fitting the Last Row

The last row almost always needs to be ripped (cut lengthwise) to fit. Measure the remaining gap at several points along the wall — walls are rarely perfectly straight, so the width may vary.

1. Measure the gap between the last installed row and the wall at both ends and the middle
2. Subtract 10mm for the expansion gap
3. Transfer these measurements to your planks and connect the marks
4. Cut along the line using a jigsaw or circular saw
5. Use the pull bar to click or slide the last row into place

If the last row is very narrow (under 40mm), it can be fragile. Be gentle when clicking and use the glue-and-slide technique if needed.

Transition Strips and Finishing

Once the laminate is down, you need to finish the edges and transitions between rooms or floor types.

Types of Transition Strips

• T-bar: Connects two floating floors at the same height (laminate to laminate between rooms)
• Reducer: Connects laminate to a lower floor (laminate to vinyl or thin carpet)
• End bar/threshold: Finishes the laminate at an external door, step, or fireplace hearth
• Stair nosing: Wraps the front edge of a stair tread

Most transition strips use a metal track screwed to the subfloor, with the decorative strip snapping into the track. Install the track before laying the laminate up to it, leaving an expansion gap on each side.

Skirting Boards and Beading

If you removed skirting boards, reinstall them now. Pin or adhesive them to the wall (never to the floor) so the floor floats freely underneath. The skirting should cover the expansion gap completely.

If you kept existing skirting in place, use scotia beading (quarter-round moulding) along the base of the skirting to cover the expansion gap. Pin the beading to the skirting, not to the floor.

Common Mistakes to Avoid

Even experienced DIYers make these errors when fitting laminate flooring. Avoid them and your floor will look and perform like a professional installation.

• Skipping acclimation: Fitting laminate straight from the box in a cold garage leads to expansion and buckling once the planks warm to room temperature
• Forgetting expansion gaps: The single most common laminate flooring failure — if the floor cannot expand, it will buckle
• Not checking the subfloor: A bump or dip in the subfloor telegraphs through the laminate and causes clicking sounds, gaps, and premature joint wear
• Not staggering joints: End joints in adjacent rows should never line up — this creates a weak point and looks like a grid pattern
• Hammering planks directly: Always use a tapping block. Hitting the edge of a laminate plank damages the click profile and makes a tight joint impossible
• Laying over damp concrete without a vapour barrier: Moisture from the slab migrates into the laminate core, causing swelling and mould growth
• Pinning the floor down: Screwing transition strips through the laminate, placing heavy items without felt pads, or wedging under door frames prevents the floor from floating
