How to Quote Rendering a House in Australia

Master rendering house quotes for Australian tradies. Learn about costs, materials, labour, and common mistakes to ensure profitable jobs.

What to Include in Your Rendering Quote

A comprehensive rendering quote should detail every aspect of the job. Start with a clear breakdown of site preparation, including cleaning, patching, and any required repairs to the substrate. Itemise materials like the specific render type, primer, and topcoat, noting quantities. Clearly state labour hours for preparation and application, along with any necessary equipment hire such as scaffolding or spray equipment. Don't forget to include waste removal, site cleanup, and your payment terms to ensure full transparency.

Typical Costs for Rendering a House in Australia

The cost of rendering a house in Australia can vary significantly, typically ranging from $40 to $100+ per square metre for a complete job, including materials and labour. This wide range depends on factors such as the existing substrate, complexity of the house (e.g., many corners, windows), choice of render type, and site accessibility. Smaller, simpler jobs might fall at the lower end, while larger, more intricate projects or those requiring specialised renders will push the price higher. Always consider the total surface area and any architectural challenges.

Understanding Material Pricing and Choices

Material costs are a significant component of your quote. Traditional cement render is generally the most economical, costing around $15-25 for a 20kg bag, covering approximately 2-3 square metres. Acrylic renders, offering greater flexibility and crack resistance, are mid-range at $50-80 per 15L pail, covering 8-10 square metres, with popular brands like Dulux AcraTex and ParexGroup being common choices. Specialised lightweight or insulation renders from suppliers like CSR or Boral will be at the higher end. Don't overlook primers and sealers; these are crucial for durability and adhesion, adding to the material cost but ensuring a quality finish.

Smart Labour Costing and Efficiency Tips

Accurate labour estimation is key to a profitable rendering job. Calculate time for thorough preparation, including masking and protective sheeting, and then estimate application time for each coat, factoring in drying periods. A skilled renderer's hourly rate might range from $60-90, or you might price per square metre for specific tasks, ensuring it covers wages, superannuation, and overheads. Always build in travel time and consider the number of renderers required for the job. Efficient planning and clear communication with your team can significantly improve job efficiency and profitability.

Common Quoting Mistakes to Avoid

One of the most frequent mistakes is underestimating the prep work involved; an improperly prepared surface can lead to costly rework. Failing to account for difficult access, such as needing extensive scaffolding, can also significantly impact your bottom line. Overlooking waste disposal costs and site cleanup time is another common pitfall. Always be explicit about the exact render type, colour, and finish to prevent client disputes. A detailed site visit is crucial to identify potential unforeseen repairs or substrate issues that could otherwise lead to scope creep and reduced profits.
