At a Glance
Sydney's inner west is full of rendered homes. From Federation brick terraces with painted cement render to 1960s brick veneers freshened up with modern acrylic finishes, rendering is one of the most popular exterior upgrades in the city. Costs range from $2,000–$18,000 per job, depending on wall area, render type, and whether scaffolding is required.
What's Included in the Price
- Surface preparation (pressure cleaning, crack repair, priming)
- Application of render to external walls (cement, acrylic, or textured finish)
- Finishing to the specified colour and texture
- Protection of windows, paths, and garden areas during application
- Cleanup
Scaffolding for work above single-storey height is a separate line item in most quotes. Confirm whether it is included. Painting after cement render is also separate, as cement render is applied in a natural grey and needs a paint coat for colour and weather protection. Acrylic render includes colour in the mix. Work must comply with NCC Volume 2 weatherproofing requirements, and any scaffolding above 4 metres must be erected to AS/NZS 1576.
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.
- Render type. Cement render is the cheapest option but requires painting afterwards. Acrylic render costs more upfront but includes colour and is more flexible. Textured coatings (e.g., Dulux AcraTex, Rockcote) sit at the premium end.
- Scaffolding. Two-storey homes and terraces with high parapets need scaffolding. This is a significant addition to the total cost and must comply with AS/NZS 1576 if above 4 metres.
- Surface condition. Clean brick in good condition is the ideal substrate. Painted brick, crumbling mortar, or old peeling render all need additional preparation before new render can be applied.
- Stripping old render. If the existing render is hollow or pulling away (tap it with a hammer and listen), it must come off before re-rendering. This adds cost but prevents the new render from failing.
- Sandstone substrates. Cement render should not be applied directly to sandstone. Sandstone needs to breathe, and cement render traps moisture, accelerating stone deterioration. Lime-based render or specific breathable systems are required for sandstone homes.
- Strata approval. In apartment buildings and townhouse complexes, rendering or re-rendering the facade may require body corporate approval, particularly if it changes the building's external appearance.
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 $18,000.
Sydney-Specific Considerations
Sydney's inner west, stretching from Marrickville and Newtown through Leichhardt and Drummoyne, has a high concentration of rendered homes. Many Federation and interwar terraces received their first cement render coat decades ago, and these coatings are now cracking, peeling, and trapping moisture behind them. Re-rendering these homes is a common job, but it requires stripping the old render first. Rendering over damaged render is a short-term fix that fails within a year or two.
Sandstone homes in suburbs like Hunters Hill, Woollahra, and parts of Mosman present a specific challenge. Sandstone is porous and needs to breathe. Traditional cement render is too hard and impermeable for sandstone, causing moisture to be trapped behind the render and accelerating the stone's deterioration. If your home is sandstone, the renderer must use a lime-based or breathable render system. Not all renderers have experience with this.
In strata buildings, particularly 1960s to 1980s apartment blocks across the eastern suburbs and north shore, facade rendering or re-rendering is typically a body corporate decision. Individual lot owners usually cannot commission external rendering work without strata approval. Check your by-laws before getting quotes.
The high demand for rendering in Sydney means lead times can extend, particularly in the cooler months when weather conditions are more predictable for rendering. Booking four to six weeks ahead is common.
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).
When hiring a renderer:
- Verify the licence number on the NSW Fair Trading website
- Ask which render system they use and why they recommend it for your substrate
- Confirm whether scaffolding is included in the quote or quoted separately
- Request references or photos of completed rendering work, particularly if your home has sandstone or heritage considerations
- Verify public liability insurance
For sandstone homes, ask specifically about lime-based render experience. Applying cement render to sandstone is a costly mistake that can damage the stone and require expensive remediation.
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.
