What Affects the Cost
Wall area. Rendering is priced per square metre. A whole house at 100–150m2 of wall area is more cost-effective per metre than a single feature wall. Minimum-job charges of $800–$1,500 apply for small patch jobs.
Render type. Cement render ($45–$65/m2 applied) is the cheapest option but requires painting afterwards. Acrylic render ($60–$85/m2) includes colour and is more flexible. Texture coats from Dulux AcraTex or Rockcote sit at the premium end ($70–$100/m2).
Scaffolding. Two-storey terraces and homes with high parapets need scaffolding. This adds $1,500–$4,000 to the total cost depending on perimeter length and hire duration.
Surface condition. Clean brick in good condition is the ideal substrate. Painted brick needs a bonding agent or mechanical preparation. Crumbling mortar or peeling old render requires additional prep that can account for 30–40% of the total job.
Stripping old render. If the existing render is hollow or pulling away (tap it with a hammer and listen for a hollow sound), it must come off before re-rendering. Removal adds $15–$30/m2 but prevents the new render from failing within a year or two.
Sandstone substrates. Cement render must not be applied directly to sandstone. Sandstone is porous and needs to breathe. Lime-based render ($80–$120/m2) or a proprietary breathable system is required. Not all renderers have experience with this.
Strata approval. In apartment buildings and townhouse complexes, facade rendering or re-rendering is typically a body corporate decision that must comply with building by-laws before work can proceed.
A single feature wall on a post-1980 brick home in the western suburbs with no scaffolding sits toward $2,000. A full two-storey terrace in the inner west requiring old render stripped, scaffolding, surface repair, and acrylic finish pushes toward $18,400.
Sydney-Specific Considerations
Inner west terraces (Marrickville, Newtown, Leichhardt, Drummoyne). Sydney's inner west has the highest concentration of rendered homes in the city. Many Federation and interwar terraces received their first cement render coat 40–80 years ago, and these coatings are now cracking, hollow, and trapping moisture against the brick. Re-rendering is a common job, but it requires stripping the old render first. Rendering over damaged render is a short-term fix that delaminates within one to two years. Expect old render removal to add $15–$30/m2 to the job. Some inner west properties also fall within heritage conservation areas, where rendering a previously unrendered facade may need council consent. Around 43% of the Inner West municipality is under some form of heritage protection.
Sandstone homes (Hunters Hill, Woollahra, Mosman). Sandstone is porous and needs to breathe. Traditional cement render is too hard and impermeable, trapping moisture behind the coating and accelerating the stone's deterioration. The correct approach is a lime-based render system, where the render is softer and more permeable than the stone beneath it. This allows moisture to move through naturally. Rockcote produces a specialist lime plaster range used in Australian heritage applications. If a renderer proposes standard cement render on sandstone, they are not the right tradesperson for the job.
Western suburbs and new estates (Marsden Park, Box Hill, Oran Park). Newer homes in Sydney's growth corridors are predominantly rendered brick veneer. These are straightforward rendering jobs when the existing surface is sound. The main consideration is cracking from minor settlement, which is common in the first 5–10 years on new builds. Acrylic render handles this movement well.
Strata buildings (eastern suburbs, north shore). In 1960s to 1980s apartment blocks, facade rendering or re-rendering is a body corporate decision. Individual lot owners usually cannot commission external rendering without strata approval. Check your by-laws before getting quotes. These projects can be substantial, as the entire building facade is typically done at once.
Demand for rendering in Sydney is consistently strong. Lead times of four to six weeks are common, particularly during the optimal autumn and spring weather windows when conditions are ideal for curing.
Hiring a Licensed Plasterer in NSW
NSW distinguishes between wet plastering (which includes rendering) and dry plastering (plasterboard). NSW Fair Trading requires a contractor licence for solid plastering and rendering work valued over $5,000 (including GST). You can verify any licence on the NSW Fair Trading register.
Worth checking:
Current NSW wet plastering contractor licence (verify the number online before signing)
Which render system they recommend for your specific substrate and why
Whether scaffolding is included in the quote or quoted separately
Photos or references from completed rendering work, particularly if your home is sandstone or in a heritage area
Public liability insurance
A written scope that specifies surface preparation, number of coats, render product, and colour
For sandstone homes, ask specifically about lime-based render experience. Applying cement render to sandstone is a costly mistake that damages the stone and can require expensive remediation later. For homes requiring exterior painting after cement render, your renderer may recommend a painter or can coordinate the timing so the render cures properly (28 days minimum) before paint is applied.
How We Calculate
Estimates are based on current licensed renderer rates in the Sydney metropolitan area, adjusted for property age and typical construction in NSW. All prices include GST. Figures cover standard residential external rendering. Commercial properties, heritage restoration, and multi-storey buildings requiring specialist access may fall outside these ranges.
