Cost to Level a Floor in 2025


Floor levelling is one of the most critical preparation steps when installing new flooring. Whether you are planning to lay timber, vinyl, hybrid, or tiles, having a flat and stable surface ensures long-term performance, comfort, and structural integrity. But how much does it cost to level a floor in Australia? The answer depends on a variety of factors, including the condition of your subfloor, the materials used, and the overall size of the job. Additionally, floor levelling costs can vary quite a lot from company to company or from private contractor to private contractor.
In this guide, we explore the costs to level a floor, the different methods used, and what you should expect from professional services or DIY options. We also break down pricing for both timber and concrete subfloors, so you can make the right choice for your home or investment property.
What Is Floor Levelling?
Floor levelling is the process of correcting an uneven subfloor surface to create a smooth, flat, and stable foundation for your new flooring material. This step is essential for avoiding soft spots, sagging floors, click-lock joint failures, and long-term damage caused by lipping or cupping. Leveling before installation ensures the flooring is built to last.
Levelling can be carried out using self-levelling compounds, timber floor levellers, concrete grinding, plywood overlays, or levelling screeds. The method depends on the type of subfloor and the final flooring material to be installed.
How Much Does Floor Levelling Cost?
The cost to level a floor in Australia typically ranges from $30 to $60 per square metre for concrete subfloors. In Sydney, the rate usually falls between $40 and $65 per square metre, including GST. Timber subfloors tend to be more expensive, with an average cost between $70 and $90 per square metre due to the increased complexity of the job.
For larger projects, the cost to level floors in a house can be estimated using square footage. On average, you can expect to pay between $3 and $5 per square foot. For a 1,000-square-foot slab, this translates to $3,000 to $5,000, depending on the method, materials, and subfloor condition.
Here is a detailed breakdown:
Floor Type | Cost Range (per m²) |
---|---|
Concrete Subfloor | $30 – $60 |
Timber Subfloor | $70 – $90 |
House Levelling | $3 – $5 per ft² |
Factors That Influence the Cost
The final cost of floor levelling depends on a range of variables:
- Subfloor Condition: Cracks, dips, wood rot, or moisture problems will increase the complexity of the job.
- Subfloor Type: Timber subfloors require different levelling techniques compared to concrete slabs.
- Access: Limited access to the work area can increase labour costs.
- Floor Area: Larger floors may qualify for volume discounts, but material costs still scale.
- Flooring Material: Hybrid and vinyl flooring require a flatter surface compared to laminate or bamboo. Laminate, engineered, and bamboo flooring can tolerate more subfloor unevenness compared to hybrid flooring.
- Installation Method: Floating floors, glue-down methods, and click-lock systems impose different flatness requirements.
- Self Levelling Compound: The type and amount of compound needed affect the price. Some projects also require a moisture barrier or skim coat.

Floor Levelling Methods
There are several common methods used in levelling floors in Australia:
1. Self-Levelling Compound
This cement-based mix flows across the floor to fill in low areas. It is ideal for concrete subfloors and is often used as part of a DIY floor levelling process. Many homeowners prefer it for its ease of use and ability to create a smooth surface with minimal effort.
- DIY self-levelling compound costs: $18 – $30 per m²
- Labour cost to self level floor (professional): included in general levelling price
2. Concrete Grinding
Used to remove high points or elevated sections in a concrete slab. This is ideal when there are isolated areas that are uneven but the majority of the slab is flat.
3. Plywood Sheeting
For timber subfloors, laying plywood boards can help create a flat base, especially when old joists have moved or settled unevenly.
Why Floor Levelling Is Important
Proper floor levelling is essential for:
- Ensuring correct installation of new flooring
- Preventing sagging floors, soft spots, and wood rot
- Avoiding failure of click-lock joins or lipping in hybrid flooring
- Complying with manufacturer warranties and Australian flooring standards
- Extending the life of your investment by providing a stable base
- Reducing tenant dissatisfaction in commercial spaces by ensuring a level subfloor.
Without a level surface, even the highest-quality flooring materials will fail prematurely.
DIY vs Professional Floor Levelling
You can level a floor yourself using self levelling compound or plywood boards, but there are risks involved:
- DIY Savings: Materials cost less, but errors can lead to costly repairs.
- Professional Services: Offer a detailed breakdown of pricing, guarantee quality, and ensure proper site preparation. A site visit is typically required for contractors to assess the specific needs of the floor leveling job.
- DIY Savings: Materials cost less, but errors can lead to costly repairs.
- Professional Services: Offer a detailed breakdown of pricing, guarantee quality, and ensure proper site preparation.
Hiring a floor levelling contractor also means they can assess your subfloor, advise on moisture issues, and use commercial-grade levelling compound. A professional floor levelling service will ensure your floor is installed properly with no future surprises.
Tips to Save on Floor Levelling Costs
- Request multiple quotes from floor levelling companies
- Bundle the floor prep and installation for a better deal
- Remove existing flooring and clean the site yourself
- Use DIY methods for small areas or simple levelling jobs
- Schedule work in off-peak periods to take advantage of better pricing
Regional Pricing and Examples
While this guide focuses on general rates across Australia, here are some regional notes:
- Floor Levelling Melbourne: Similar to Sydney pricing, usually $40–$70 per m²
- Floor Levelling Brisbane: Concrete floor preparation costs $30–$55 per m², especially for hybrid installations
- Floor Relevelling Sydney: Timber floor relevelling often starts at $75 per m²
- Subfloor Replacement Cost Australia: If full subfloor replacement is needed, expect $150–$300 per m² depending on foundation, joists, and materials
Final Thoughts
Floor levelling is a critical and often underestimated step when preparing for new floors. Whether you're renovating a home, installing hybrid flooring in a rental, or upgrading your space with hardwood, understanding how much floor levelling costs will help you budget effectively.
You can expect a cost to level a floor between $30 and $90 per square metre, depending on the surface, method, and location. For more complex jobs or large floor areas, this can mean several thousand dollars in total floor preparation costs.
