How Much Does a Plasterer Cost?

When planning any renovation or repair project, understanding how much a plasterer costs is essential. Whether you're repairing water damage, updating decorative cornices, or plastering an entire home, the cost of plastering work, specifically how much does a plasterer cost, varies depending on several factors. In this guide, we explore plastering prices across Australia, including ceiling plastering cost, plasterboard installation, and how to hire experienced professionals for quality work.

Average Cost of Hiring a Plasterer

On average, the plastering cost in Australia ranges from $23 to $90 per square metre, depending on the type of plastering job, the complexity of the task, and the material used. Plasterers may charge by the hour or provide a flat rate. Hourly rates in Australia typically range between $45 and $105.

For a straightforward plasterboard installation, costs usually range between $15 to $30 per square metre, including both labour and materials. Wall plastering usually falls between AUD $15 and $25 per square metre, depending on the complexity. Ceiling plastering generally costs between $25 and $40 due to the increased difficulty and height involved.

Regional Price Differences

Plastering costs, including average costs, vary significantly across different regions. For example, Brisbane homeowners may pay $15 to $20 per square metre, whereas those in Sydney and Melbourne are likely to encounter rates between $20 and $25 per square metre.

Types of Plastering Techniques

The type of plastering technique used can influence the final cost and appearance of your space. Below are the most common plastering methods found in Australian homes, which can serve as a price guide .

Skimming

Skimming is a thin layer of plaster applied to old plaster walls or ceilings. It is commonly used to restore older buildings and costs between $200 and $750 for walls, and from $470 to over $950 for ceilings.

Float and Set

This technique involves two layers — a backing layer and a final coat. It is suitable for rough surfaces and often used in new builds or during full plastering renovations. Float and set plastering is a specific technique involving these two layers: backing plaster and finishing plaster.

Ornamental Plastering

Decorative cornices, arches, and mouldings fall under ornamental plastering. These features are often used in public buildings or heritage homes to enhance aesthetic value and form.

Cement Rendering

Cement render, a hard plaster applied to external walls or wet areas, provides added durability and moisture resistance. This type of plastering adds to the overall cost of plastering as it is typically more expensive due to its resilience.

Plasterboard and Gyprock

Gyprock, or plasterboard, is the most common material used for internal walls and ceilings. It is made from hardened wood pulp and gypsum, offering sound insulation and a durable wall finish. Plaster is more resistant to damage than drywall, making it a durable choice for walls.

Lime Plaster and Blue Board

Lime plaster offers breathability and is often found in older or high-end properties. Blue board, on the other hand, is water-resistant and used in bathrooms and kitchens.

Factors That Influence Plastering Cost

Several factors influence the total cost of how much plastering costs, including the size of the project, complexity of the task, and your location.

Project Size and Area

Larger rooms or entire homes require more materials and labour, which affects the overall cost. A small room might cost a few hundred dollars, whereas plastering an entire house can cost between $10,000 and $15,000.

Type of Plaster

The type of plaster used — such as lime plaster, wet plaster, or cement render — significantly impacts the final price. Fire resistant and moisture resistant materials typically cost more.

Number of Coats

Some jobs require multiple coats for durability and a smooth finish. Each additional layer increases both material and labour cost.

Height and Accessibility

High ceilings or difficult-to-reach areas may require specialised equipment like scaffolding or mechanical lifts. This increases the labour intensity and cost. Higher ceilings require special mechanical enhancements, which can further increase the cost of plastering.

Location

Plastering prices can be higher in metropolitan cities due to increased labour rates and overheads. Hiring local plasterers can help reduce logistics-related costs. You can save costs by hiring a local plasterer to reduce travel time and expenses.

Preparation and Clean-Up

Jobs that require removal of old plaster, patching of holes, or significant surface preparation will incur additional costs. Cleanup after the job is often quoted separately or built into a flat rate.

Ceiling and Wall Plastering

Ceiling plastering is often more labour intensive than wall plastering due to accessibility. It generally costs between $25 and $40 per square metre. Skimming ceilings can cost upwards of $950 depending on the area and number of coats required.

Wall plastering is slightly more affordable, typically ranging from $15 to $25 per square metre. The type of wall surface — whether old plaster, timber, or gyprock — will also influence pricing.

Plasterboard Installation and Skimming Costs

Installing plasterboard (also referred to as drywall) is common in most rooms across Australia. Plasterboard installation costs, which can include plaster repairs, between $15 and $30 per square metre and includes both materials and labour. It is often used in new builds or during full renovations.

Skimming, which involves applying a thin coat over existing plaster to create a fresh surface, is ideal for repairs or aesthetic upgrades. This method is particularly popular for repairing damaged walls or covering up old paint, showing how much does plastering cost in these scenarios. Small cracks in plaster can be easily repaired or replastered, ensuring longevity and maintenance of appearance.

Full Room and Whole House Plastering

Plastering an entire room may be charged as a flat rate. For example:

• Small room: $500 to $1,200
• Medium-sized room: $1,000 to $1,800
• Large room: $2,000 or more

The cost to plaster an entire home ranges from $10,000 to $15,000 depending on the size of the house, quality of materials, and labour required. Larger projects often benefit from fixed price quotes which can offer better cost certainty. It's wise to schedule a series of days for larger plastering jobs to ensure continuity.

Benefits of Professional Plastering

Hiring a professional plasterer offers several advantages:

• Durable Finish: Properly plastered walls last for decades and provide a smooth, durable wall finish. Plaster creates an even and durable finish ready for the next part of a home improvement project.
• Sound Insulation: Plaster offers acoustic benefits, especially important in recording studios or multi-storey homes.
• Fire Resistance: Many types of plaster are fire resistant, enhancing safety.
• Versatile Aesthetics: Decorative options like ornamental plastering or coloured lime plaster allow custom designs.
• Clean Application: Modern plastering techniques leave minimal residue, making cleanup easier.

How to Hire a Qualified Plasterer

Choosing the right plasterer ensures quality work and avoids costly errors. Here are key tips:

• Always hire a licensed and insured professional plasterer.
