How to Install Laminate Flooring: A Step-by-Step DIY Guide for Homeowners in NZ
Laminate flooring has become one of the most popular flooring choices for modern homes because it is durable, affordable, and relatively easy to install. Many homeowners in NZ choose laminate flooring because most modern products use a click-lock floating floor system, which allows planks to connect without nails or glue.
If you're planning to upgrade your floors, installing laminate flooring yourself can be a rewarding project. However, proper preparation and correct installation techniques are essential to ensure your floor lasts for years without gaps, swelling, or uneven surfaces.
This guide explains how to install laminate flooring step by step, along with preparation tips and common mistakes to avoid.

Tools and Materials Needed
Before starting your installation, make sure you have the right tools and materials.
Essential Tools
- Tape measure
- Rubber mallet
- Tapping block
- Pull bar
- Utility knife
- Spacers for expansion gaps
- Jigsaw or circular saw
- Level
Materials
- Laminate flooring planks
- Underlayment or vapour barrier
- Transition strips
-
Baseboards or skirting boards
Having the proper tools helps ensure the flooring locks together properly and prevents damage to the plank edges.
Step 1: Acclimatise the Laminate Flooring
Laminate flooring must acclimate to your home's temperature and humidity before installation.
Stack the unopened boxes of laminate flooring in the room where they will be installed for at least 24–48 hours. This allows the planks to expand or contract naturally.
Proper acclimatisation helps prevent:
- Plank expansion after installation
- Gaps are forming between boards
-
Buckling caused by humidity changes
In homes located in coastal climates like Auckland, humidity fluctuations make this step especially important.
Step 2: Prepare the Subfloor
A smooth and clean subfloor is essential for a successful laminate flooring installation.
Before installing the planks:
- Remove all debris, dust, and old flooring materials
- Ensure the surface is level
- Repair any damaged areas of the subfloor
- Remove existing base mouldings
Uneven subfloors can cause laminate flooring to feel unstable or create clicking sounds when walked on.
Step 3: Install the Underlayment or Vapor Barrier
Underlayment plays an important role in laminate flooring installation.
It helps to:
- Reduce noise when walking
- Improve comfort underfoot
- Protect flooring from moisture
Roll the vapor barrier or underlayment across the floor, starting along the longest wall.
Some manufacturers recommend overlapping seams, while others require them to be placed side-by-side and sealed with tape. Always follow the installation instructions provided with your flooring.
Step 4: Trim Door Jambs for a Professional Finish
To achieve a seamless look, laminate planks should slide underneath door jambs.
Place a plank on the floor next to the door frame and use it as a guide to mark the correct cutting height.
Using a coping saw or flush-cut saw:
- Cut the door jamb parallel to the subfloor
- Remove the trimmed piece
-
Slide the plank underneath
This technique avoids visible gaps and gives the floor a cleaner finish.
Step 5: Install the First Row of Laminate Planks
- Start laying the flooring along the longest straight wall in the room.
- Place the first plank with the groove side facing the wall.
- Insert spacers between the wall and planks to create an expansion gap. Laminate flooring expands and contracts slightly due to temperature and humidity changes.
- Typical expansion gaps are around 8–10 mm.
- Continue laying planks along the wall, connecting them using the click-lock mechanism.
Step 6: Continue Installing the Remaining Rows
Once the first row is complete, continue installing additional rows.
Tips for proper installation:
- Stagger the plank joints for better stability
- Use a tapping block to secure tight connections
-
avoid forcing planks together
Staggering joints improves the structural strength of the floating floor and creates a more natural appearance.
Step 7: Cut and Install the Final Row
The last row often needs to be trimmed to fit the remaining space. Measure the gap carefully and cut the planks to size using a saw. Use a pull bar to secure the final row into place.
Ensure the expansion gap remains between the planks and the wall.
Step 8: Install Thresholds and Base Moulding
Once all planks are installed:
- Remove the expansion spacers
- Install baseboards or skirting boards
-
Attach transition strips where the flooring meets other surfaces
These finishing touches hide the expansion gaps and give the room a polished look.
Common Mistakes When Installing Laminate Flooring
DIY installers often run into problems that can reduce the lifespan of the flooring.
Avoid these common mistakes:
- Skipping the Acclimatisation Step
- Installing Laminate on Uneven Subfloors
- Forgetting Expansion Gaps
- Using Excessive Moisture During Cleaning after Installation
-
Forcing Planks Together Instead of Using Proper Tools
Preventing these mistakes will help your floor remain stable and durable.
