Cost of Carpet Replacement Per Square Metre

Replacing carpet is one of the most effective ways to refresh your home’s interior, improve comfort underfoot, and boost property value. But before you dive in, it is important to understand the full range of costs involved. From materials and labour to carpet removal and furniture moving, the final cost of carpet replacement can vary depending on several factors.

In this detailed guide, we break down the average carpet replacement cost per square metre, explain what influences the overall cost, and help you make informed decisions whether you are replacing carpet in one bedroom or an entire house.

Carpet Replacement Cost Overview

On average, the cost of carpet replacement in Australia ranges from 55 to 75 dollars per square metre. This figure typically includes both supply and professional installation. However, simple installations can start as low as 20 to 25 dollars per square metre, especially for basic carpet materials or low-cost jobs.

For a large bedroom measuring 5 metres by 4.2 metres (21 square metres), the average cost sits around 1,365 dollars. This estimate reflects the typical cost of carpet installation for a room of this size, including materials and labour. Smaller rooms like a 2 metre by 3 metre bedroom could cost approximately 550 dollars, while larger rooms like a 4 metre by 5 metre space may reach 950 dollars or more.

Carpet removal is an additional expense, generally costing 10 to 25 dollars per square metre. Furniture removal and subfloor preparation may also attract further fees. Replacing carpet in a full house may range from 1,200 to 6,500 dollars, depending on total area and material selection.

Factors That Influence Carpet Installation Costs

There are several key factors that influence carpet installation costs. Understanding them can help you budget effectively and avoid unexpected charges.

1. Room Size and Layout

The size of your room is the most obvious factor. Larger rooms or entire homes require more material and time to install. Rooms with complex layouts, alcoves, or curved walls will require extra cuts and potentially more carpet, increasing waste and cost.

2. Carpet Material

The type of carpet material significantly affects price. Polyester is the most budget friendly, often costing as little as 6 dollars per square metre, while wool carpet can range from 60 dollars and up. Nylon and acrylic are good mid-range options, often costing between 30 and 45 dollars per square metre, making them popular choices for family homes.

Material quality also impacts carpet life, durability in high traffic areas, and stain resistance. Choosing a cost effective carpet material suited to your lifestyle and foot traffic level ensures better value long term.

3. Underlay Selection

Good underlay improves comfort, provides noise reduction, and can extend the life of your carpet by up to 5 to 10 years. Underlay quality varies, and so does its cost. Basic foam underlay might cost 5 to 10 dollars per square metre, while premium rubber underlay can exceed 15 to 20 dollars per square metre. The cost of underlay also depends on its thickness and quality, which can significantly impact the overall comfort and durability of your carpet.

4. Labour Costs

Labour charges generally fall between 25 and 35 dollars per square metre, depending on your location and the installer’s experience. Hiring professionals ensures the carpet is installed properly and reduces the chance of wrinkling or premature wear.

5. Subfloor Preparation

A clean, even subfloor is essential for successful carpet laying. If the subfloor is damaged or uneven, additional work may be required before carpet installation begins. This can add to your final cost, as preparing your flooring may involve repairs or levelling to ensure a smooth surface for the new carpet.

6. Carpet Removal and Disposal

Removing old carpet and disposing of it can cost between 10 and 25 dollars per square metre. Some carpet installers include this in their quote, while others list it as an additional service. Always ask what is included.

7. Furniture Moving

If your installer needs to move furniture before laying the new carpet, you may be charged an extra fee. This cost can vary depending on the number and size of items involved.

Estimating Carpet Installation Costs

To estimate the cost of your project, start by measuring each room’s width and length. Multiply these dimensions to calculate the area in square metres. Always add 10 to 20 percent extra to account for waste, offcuts, and awkward spaces. This additional percentage ensures you have enough material to cover unusual shapes or corners without running short.

For example, a lounge room measuring 4 metres by 6 metres will need 24 square metres of carpet. Adding 15 percent for waste brings the total to about 27.6 square metres.

If the average installation cost is 65 dollars per square metre, then the estimated cost for this room would be:

27.6 x 65 = 1,794 dollars

For a full house of 186 square metres (the average house size in Australia), total installation costs could reach 12,090 dollars.

Most carpet suppliers and installers will offer a free measurement service as part of the quote process. Taking advantage of this can help ensure accuracy and avoid over-ordering or unexpected fees.

DIY vs Professional Carpet Installation

You might consider DIY installation to save on labour, but this approach comes with risks. DIY carpet installation can save you money on labour costs but requires time, effort, and skill to achieve a professional finish.

Benefits of DIY

• Labour savings
• Can work at your own pace
• Suitable for small, low-priority rooms

Drawbacks of DIY

• Requires specific tools and experience
• Poor installation can lead to premature wear, wrinkling, or visible seams
• No warranty on workmanship
• Extra time and effort

Poor installation in DIY projects can result in issues like wrinkling and uneven seams, which may increase costs over time due to the need for repairs or reinstallation.

Unless you have the tools and experience, hiring professionals is usually the best option. Reputable carpet installers offer a warranty and ensure a seamless finish. Complex areas like stairs, hallways, and large living rooms especially benefit from professional work. Professional installers have the necessary tools and expertise to deliver high-quality results, ensuring your carpet is installed correctly and lasts longer.

Types of Carpet Materials and Their Costs

There are many carpet types available to suit different budgets and homes. Here is a quick breakdown of the most common materials:

Polyester

• Cost: from 6 dollars per square metre
• Best for: Low budget, rental properties
• Pros: Affordable, stain resistant
• Cons: Less durable, shorter carpet life

Nylon

• Cost: 30 to 45 dollars per square metre
• Best for: Family homes with pets or kids
• Pros: Durable, affordable, pet friendly carpet option
• Cons: Can flatten under heavy furniture

Wool

• Cost: 60 dollars and up per square metre
• Best for: Premium homes
• Pros: Natural fibre, excellent insulation, stain resistant
• Cons: Expensive, needs proper maintenance

Blends and Others

• Blends of wool and synthetic fibres combine benefits of both
• Solution-dyed carpets offer high fade resistance

Your final cost will vary depending on material selection, the brand, whether carpet retailers offer discounts, and whether you bundle with underlay and installation.

Tips for Hiring Carpet Installers

Choosing the right installer can make a significant difference in the result. Keep the following tips in mind:

• Compare quotes from at least three carpet installers
• Look for positive reviews and a proven track record
• Ask if they include furniture removal and disposal
• Ensure they are experienced in carpet laying
• Check if they offer a warranty on installation

Many carpet retailers partner with installers or offer bundled packages, which can save money and time. Choosing a reputable carpet installer will help your new carpet last longer and look better.

Additional Considerations and Costs

Carpet Life and Maintenance

The lifespan of your new carpet depends on the material, installation method, and maintenance. High traffic areas benefit from tougher materials like nylon, while bedrooms can use softer, more luxurious fibres.

Impact on Home Value

New carpet enhances the look and feel of your home, improves indoor air quality, and can add to property value—especially important if you are preparing a home for sale or rent.

Budgeting Effectively

When budgeting, remember to account for:

• Carpet cost per square metre
• Underlay
• Labour
• Carpet removal and disposal
• Furniture moving
• Additional services

A comprehensive quote helps you understand the total cost and avoid surprise fees later.

The cost of carpet replacement per square metre in Australia typically ranges between 55 and 75 dollars, but the total project cost depends on room size, material, installer fees, and additional services. Replacing carpet is a cost-effective choice for refreshing your living space, especially when installed by professionals.

Whether you are changing carpet in one bedroom or your entire house, planning ahead and comparing multiple quotes will help you stay within budget and choose the best value carpet for your home.
