How to install laminate flooring (2026)
Quick Answer
To install laminate flooring, you prepare a clean, level, dry subfloor, let the boards acclimatise if the manufacturer requires it, lay any required underlay or moisture barrier, then click the planks together row by row while maintaining the specified expansion gap at walls and fixed objects. Finish by trimming edges where needed and refitting skirting boards or adding scotia so the floor can still move. Always follow the flooring maker’s installation instructions, because locking system details, subfloor requirements and moisture rules vary by product.
Overview
Laminate flooring is usually installed as a floating floor, which means the boards lock to each other rather than being fixed directly to the subfloor. The job is straightforward if the room is well prepared, but most failures come from poor preparation rather than from the click-together part. The subfloor needs to be flat, dry, sound and clean so the laminate can sit evenly without flexing, separating or wearing prematurely. You also need to allow the floor to expand and contract naturally with changes in temperature and humidity, which is why manufacturers require perimeter expansion gaps and specific transition details at doorways or between rooms. Before you begin, check whether your laminate already has an attached underlay, whether a separate vapour barrier is required for your subfloor type, and whether the product is suitable for the room. Read the manufacturer’s guide fully before opening packs. Plan the layout so you avoid awkward narrow strips at one side of the room and stagger end joints for strength and appearance. Work methodically, keep rows straight, and stop if boards are resisting; forcing them can damage the locking profile. If you prepare properly and follow the product instructions closely, a laminate floor can go down neatly and last well.
Who this is for
DIYers installing click-lock laminate flooring in dry internal rooms such as living rooms, bedrooms, hallways and similar spaces, where the product manufacturer permits the installation method and subfloor type.
What you’ll need
- Laminate flooring packs
- Manufacturer installation instructions
- Suitable underlay if required
- Suitable vapour barrier or damp-proof membrane if required for the subfloor
- Spacers for the perimeter expansion gap
- Tape measure
- Pencil or marking tool
- Straight edge or square
- Fine-tooth saw, jigsaw, laminate cutter or other manufacturer-suitable cutting tool
- Tapping block and pull bar if recommended by the flooring maker
- Utility knife for trimming underlay
- Vacuum or broom
- Level or straightedge to check flatness
- Appropriate door bar or transition profile where needed
- Skirting boards or scotia/beading if you are using them to cover the expansion gap
- Personal protective equipment suitable for cutting and handling materials
Before you start
Confirm the laminate is suitable for the room and subfloor, including any restrictions for bathrooms, conservatories, underfloor heating or large continuous areas. Check the subfloor is structurally sound, dry and flat to the tolerance stated by the flooring manufacturer. Read the laminate, underlay and subfloor preparation instructions together so they do not conflict. If you have concrete or another mineral subfloor, check whether the manufacturer requires a moisture test or specific vapour barrier. Plan whether you will remove skirting boards or keep them in place and cover the expansion gap with scotia. Undercut door frames if needed so the laminate can slide underneath without being pinned.
Step-by-step
- 1
Read the product instructions and inspect the room
Read the laminate flooring instructions, underlay instructions and any guidance for trims or underfloor heating before opening all packs. Check the room conditions, confirm the subfloor type, and inspect the boards for visible damage or manufacturing defects.
Why: Laminate systems vary, especially the locking mechanism, underlay requirements and moisture rules. Catching incompatibilities or damaged boards early prevents wasted time and invalidated warranties.
- 2
Prepare the subfloor properly
Remove old floor coverings, protruding fixings, debris and dust unless the manufacturer specifically allows installation over the existing surface. Repair loose, damaged or uneven areas and make sure the subfloor is clean, dry, solid and within the flatness requirement stated by the flooring manufacturer.
Why: An uneven or unstable base causes movement, joint failure, hollow spots, edge damage and premature wear. Cleanliness also matters because grit trapped underneath can create noise and pressure points.
- 3
Acclimatise materials if required and plan the layout
Store the unopened flooring packs in the room as the manufacturer advises, then measure the room and dry-plan the board layout. Aim for balanced board widths across the room where possible, and decide the laying direction, usually based on the room shape, incoming light or manufacturer guidance. Plan staggered end joints according to the product instructions.
Why: Acclimatisation helps the material adjust to room conditions where required, reducing movement issues after installation. Planning the layout avoids very narrow edge pieces and gives a stronger, neater finished floor.
- 4
Lay the underlay and moisture barrier if required
Install any required vapour barrier and underlay in the direction and overlap arrangement stated by the manufacturer. Keep it flat, trim it neatly and tape joins only if the product instructions say to do so. Do not double up underlay unless the flooring maker expressly allows it.
Why: The correct base layer helps with moisture control, sound reduction and support. Too much cushioning or the wrong moisture protection can cause joint failure, bounce or moisture damage.
- 5
Start the first row straight and maintain expansion gaps
Use spacers at the walls and around fixed objects to maintain the expansion gap specified by the flooring manufacturer. Lay the first row carefully, checking it is straight, and cut the final board in the row to length if needed. Keep the cut edge where it will be hidden if possible.
Why: The first row sets the line for the whole floor. If it starts out crooked, every row after it becomes harder to fit. The expansion gap is essential because laminate expands and contracts with room conditions.
- 6
Install the remaining rows without forcing the joints
Continue row by row using the locking method specified for your flooring. Stagger end joints as instructed, support long boards while clicking them together, and use a tapping block or pull bar only if the manufacturer permits it. Cut boards neatly around door frames, radiator pipes and other obstacles, while preserving the required expansion space.
Why: Correct engagement of the click joints prevents gaps, edge chipping and weak seams. Forcing joints or striking them incorrectly can damage the locking profile and cause later separation.
- 7
Fit the final row and any transitions
Measure the final row accurately, rip boards to width if required, and install them with the correct expansion gap still in place. Fit doorway trims or transition profiles as specified, especially where the floor meets another surface or where the manufacturer requires a break between areas.
Why: The last row often determines how neat the finished floor looks. Proper transitions protect exposed edges and allow movement where one continuous floating floor run is not suitable.
- 8
Finish without pinning the floor down
Remove spacers, then refit skirting boards or install scotia/beading to cover the gap without fixing through the laminate. Clean the floor using methods approved by the manufacturer and keep the installation instructions and spare boards for future repairs.
Why: A floating floor must remain free to move. Fixing trim through the laminate can trap it, leading to buckling, noise or joint stress.
Why this works
Laminate performs best when it is fully supported, kept dry from below where required, and allowed to move slightly as room conditions change. The click-lock joints create a stable floating surface, but they rely on a flat subfloor, correct underlay and free movement at the edges.
Common mistakes to avoid
- Installing over an uneven or damp subfloor
- Skipping the manufacturer instructions and assuming all click systems are the same
- Forgetting or reducing the required expansion gap at walls, pipes and door frames
- Using the wrong underlay, or stacking underlays when not allowed
- Forcing boards together and damaging the locking edge
- Failing to plan the layout, leaving a very narrow first or last row
- Fixing skirting, beading or heavy built-ins through the floating floor
- Not using the required transition profile between areas when the manufacturer specifies one
Troubleshooting
Boards will not click together cleanly
Check for debris in the groove, verify you are using the correct angle or sequence for that locking system, and make sure the subfloor is not causing the board to rock. Replace any board with a damaged locking edge.
Gaps appear between planks after fitting
Check whether the joint was fully engaged during installation, whether the subfloor is uneven, or whether the floor has been pinned at the perimeter. If caught early, affected rows may need to be lifted and reinstalled correctly.
The floor feels bouncy or sounds hollow
Inspect for subfloor low spots, the wrong underlay, debris trapped underneath or an unsupported area. Severe unevenness usually means the floor must be lifted and the subfloor corrected.
Boards are lifting or peaking near walls
Look for blocked expansion gaps, trim fixed through the floor, or a run that exceeds the manufacturer’s permitted dimensions without a transition break. Relieve the restriction and reinstall affected edges if necessary.
Edges chip while cutting
Use a suitable blade or cutter for laminate, support the board properly, mark carefully and follow the tool guidance for the cleanest cut direction.

Alternatives
- Hire a flooring fitter if the room has an uneven subfloor, many awkward cuts or unclear moisture conditions
- Consider luxury vinyl flooring if the room has higher moisture exposure and the product is approved for that environment
- Choose engineered wood if you want a real wood wear layer and the subfloor and budget suit it
Pro tips
- Open only as many packs as you need to inspect and fit so boards stay protected and easy to return if defective.
- Mix boards from different packs as you install for a more natural variation in pattern and shade.
- Keep a small offcut to check the expansion gap quickly around the room.
- Photograph the product labels and batch details before disposal in case you need matching boards later.
- Undercutting architraves usually gives a neater result than cutting the laminate tightly around them.
Safety notes
- Wear eye protection and suitable dust protection when cutting boards or trimming underlay.
- Handle planks carefully; cut edges can be sharp and packs can be heavy.
- Use power tools only as directed by the tool manufacturer.
- Keep the work area clear to reduce trip hazards from loose boards, offcuts and spacers.
- Check for hidden pipes or cables before trimming door frames or altering adjoining finishes.
Legal & regulatory notes
Building and product requirements vary by location, especially for moisture barriers, acoustic performance in flats, fire considerations for common areas, and suitability over underfloor heating. Follow the flooring manufacturer’s instructions and any local building regulations or lease requirements that apply to your property.
What this guide does not cover: This guide covers standard click-lock laminate in typical internal rooms. It does not give brand-specific measurements, moisture test limits, underfloor heating settings, stair installations, or specialist commercial requirements, which must come from the product manufacturer and local regulations.
Cost considerations
The main cost differences usually come from subfloor preparation, the type of underlay or moisture barrier required, and the need for trims, new skirting or professional fitting. A cheap laminate installation can become expensive if an uneven or damp subfloor is ignored and the floor has to be lifted and replaced.

Do I need underlay under laminate flooring?+
Usually yes, unless the laminate has an integrated underlay and the manufacturer says no additional layer is needed. You may also need a separate vapour barrier depending on the subfloor, especially over concrete or other mineral bases.
Can laminate flooring go over existing flooring?+
Sometimes, but only if the existing surface is suitable, flat, sound and approved by the laminate manufacturer. Soft, unstable or damaged surfaces are a poor base and should usually be removed.
Should laminate run parallel to the longest wall?+
That is a common choice, but it is not a rule. The best direction depends on the room layout, light, adjoining floors and the manufacturer’s guidance.
Can I put heavy furniture on laminate after installation?+
Laminate flooring is designed to take normal furniture loads, but a floating floor still needs freedom to move at the edges. Avoid trapping the floor with fixed cabinetry or trims unless the manufacturer specifically allows that arrangement.
Do I glue laminate flooring down?+
Most modern laminate for DIY installation is a floating click system and is not glued to the subfloor. Always follow the specific product instructions because some edge-sealed or specialist systems may differ.
