What Affects the Cost
Wall area. Rendering is priced per square metre. A full single-storey house (100–150m2 of wall) is more cost-effective per metre than a single feature wall or entranceway.
Render type. Cement render ($45–$65/m2 applied) is the cheapest but needs painting. Acrylic render ($60–$85/m2) includes colour and is more flexible, reducing hairline cracks over time. Unitex is a popular acrylic system across Melbourne, alongside Dulux AcraTex and Rockcote.
Scaffolding. Many Melbourne double-brick homes from the 1960s to 1980s are two-storey, making scaffolding a common addition to rendering quotes.
Surface preparation. Melbourne's double-brick homes generally provide an excellent substrate. Painted brick needs a bonding agent or mechanical preparation (sanding, chemical stripping of loose paint). Old mortar joints in poor condition need repointing before rendering.
Existing render removal. Failing render must be stripped before re-rendering. This adds $15–$30/m2 but prevents the new coat from delaminating.
Heritage overlay. Properties in heritage overlay areas may face restrictions on external changes including render colour, finish type, or whether rendering is permitted at all. Check with your local council before committing.
A single feature wall or entranceway on a single-storey brick home with clean walls sits toward $2,000. A full two-storey double-brick home requiring scaffolding, surface repair, old paint removal, and acrylic finish pushes toward $17,800.
Melbourne-Specific Considerations
Eastern and south-eastern suburbs (Doncaster, Templestowe, Glen Waverley, Box Hill, Oakleigh, Clayton, Bentleigh). These suburbs are filled with 1960s to 1980s double-brick homes that are ideal candidates for rendering. The solid, rigid brick substrate provides excellent adhesion with minimal movement, so render lasts well and cracks are uncommon. Unlike timber-framed homes with sheet cladding, double-brick has no flex at joins that could cause render to crack. A modern acrylic render in a contemporary colour transforms these homes for a fraction of the cost of recladding or rebuilding.
Heritage overlay areas (Fitzroy, Carlton, South Melbourne, Hawthorn). Rendering a previously unrendered brick facade may not be permitted in heritage overlay areas. Each council has specific guidelines: the City of Yarra, for example, has detailed heritage design guidelines that cover external finishes. Even in heritage areas, rendering is sometimes allowed on non-contributory buildings, but check before proceeding. If your terrace was originally face brick and a previous owner rendered it, restoring the original brick may actually be the heritage-compliant option. The Victorian Building Authority (VBA) can advise on permit requirements.
Western suburbs and reactive soils (Werribee, Point Cook, Truganina, Tarneit). Parts of Melbourne's west sit on reactive clay soils that expand when wet and shrink when dry. This seasonal ground movement translates to hairline cracking in rendered walls. Acrylic render handles this movement better than rigid cement render. If cracks reappear within months of rendering, the underlying soil movement may need investigation before re-rendering makes sense.
Climate and timing. Melbourne's cool winters and variable rainfall mean timing matters. The best rendering conditions are autumn (March to May) and spring (September to November), when temperatures are moderate and rain is less persistent. Summer is generally fine, but hot northerly days above 35 degrees C affect curing. Winter rendering is possible but requires careful weather monitoring, as rain on fresh render within the first 24 hours can wash out the surface.
The brick-to-render conversion is so popular in Melbourne that the market is competitive. Get at least three quotes and compare not just price but the render system proposed, the level of surface preparation included, and whether scaffolding is in or out of the quote.
Hiring a Licensed Plasterer in VIC
In Victoria, the Victorian Building Authority (VBA) administers building practitioner registration. Single-trade rendering work does not require VBA registration. When rendering is part of a larger building project involving multiple trades, registration requirements may apply to the builder overseeing the work. You can search for registered practitioners on the VBA practitioner register.

How We Calculate
Estimates are based on current renderer rates in the Melbourne metropolitan area, adjusted for property age and typical construction in VIC. All prices include GST. Figures cover standard residential external rendering. Commercial properties, heritage restoration, and multi-storey buildings may fall outside these ranges.
