Quick Answer

Rendering a house in Melbourne costs $25–$65 per square metre for the wall surface area, depending on render type and finish. A typical Melbourne brick veneer home (150–200m² external wall area) costs $4,000–$12,000 to render fully. Acrylic render is the most affordable at $25–$40/m²; texture coat finishes cost $35–$55/m²; Venetian or specialty finishes cost $55–$100/m².

Complete Rendering Cost Breakdown

By Render Type

Render Type Cost per m² Durability Best For
Cement render (sand/cement) $25–$40 20–30 years Budget option, paint over
Acrylic render $30–$50 15–25 years Flexible, crack-resistant
Polymer/texture coat $35–$55 20–30 years Textured finishes, modern homes
Tyrolean/pebble dash $30–$45 25–35 years Older homes, rough texture
Venetian plaster $60–$100 20–30 years Interior feature walls
Rockcote/specialty $50–$80 20–25 years Premium exterior finish
Pro tip: Acrylic render is the best all-round choice for Melbourne’s climate — it flexes with temperature changes, resists cracking, and holds paint better than traditional sand/cement. Most SE Melbourne renders use acrylic as the top coat.

Grinding back and filling cracks before applying new render
Grinding back and filling cracks before applying new render — skipping this prep step is the most common cause of render failure within 3–5 years, as new render over cracks simply re-cracks in the same spots.

What Affects Rendering Costs in Melbourne?

1. Surface Preparation

Poorly prepared walls are the #1 cause of render failure. Preparation includes pressure cleaning ($200–$400), removing loose paint or old render ($300–$800), filling cracks ($100–$500), and applying bonding primer ($150–$400). Budget $500–$1,500 for surface preparation on a typical Melbourne brick home. Older homes in Dandenong, Berwick, and Narre Warren areas built before 1990 often have porous brickwork needing extra sealing.

2. Scaffolding for Double-Storey Homes

Single-storey homes can usually be rendered from ladders and platforms. Double-storey homes require scaffold hire — add $800–$2,500 for a week of scaffold on a typical Melbourne double-storey. Some renderers include this in their quote; always confirm upfront.

3. Number of Coats

Quality rendering requires 2–3 coats: scratch coat (adhesion), brown/levelling coat, and finishing coat. Budget rendering with a single coat looks cheap and cracks within 5 years. Insist on a multi-coat system and ask for the product data sheet from the renderer.

4. Finish and Colour

Plain flat finishes cost the least. Textured finishes (quartz aggregate, pebble, rough-texture) cost $5–$15/m² more. Integral colour (colour mixed into the render, not painted on) adds $3–$8/m² but eliminates future repainting costs. Premium finishes like Rockcote or Unitex are 30–50% more than generic products but carry manufacturer warranties of 10–15 years.

5. Rendering Around Windows and Doors

Window and door reveals, sills, and architraves require extra time and skill. Renderers typically add $20–$60 per opening for reveal work. A home with 15 windows and 3 doors adds $360–$1,080 in reveal costs.

DIY vs Professional Rendering

Rendering is a skilled trade — amateur rendering is immediately obvious (inconsistent thickness, trowel marks, patches, cracking). DIY renders on small patch repairs or garden walls are manageable with bagged acrylic render products from Bunnings or Mitre 10 ($15–$40/bag). Full exterior DIY rendering on a house is not recommended unless you have plastering/rendering experience — poor application causes cracking and water infiltration.

Professional renderers hold a plastering licence in Victoria. For exterior rendering requiring scaffolding or involving load-bearing walls, a licensed tradesperson is required. Verify licences at the Victorian Building Authority.

Common Rendering Problems

Problem Symptom Action
Map cracking Spider web crack pattern on surface Poor surface prep or drying too fast. Cut back to sound material, re-prep, re-render
Delamination Hollow-sounding patches, bubbling or peeling Remove affected area, prime surface, re-render in sections
Efflorescence White powdery salt deposits on surface Water penetration from behind. Fix source (gutters, damp), brush off deposits, seal and repaint
Impact damage Chips, holes, dents in render face Score edges, apply bonding primer, fill with matching render product
Colour variation Patchy, uneven colour after painting Prime before painting. Dark colours show variation more. Apply 2 coats of exterior masonry paint
Pro tip: If your Melbourne home has existing render with hairline cracks but the render is still bonded (not hollow-sounding), a coat of flexible masonry sealer ($3–$5/m²) and repaint may be all you need rather than a full re-render.
Applying exterior masonry paint over fresh render
Applying exterior masonry paint over fresh render — two coats of quality paint (Dulux Weathershield or Solver Exterior) adds critical UV and water protection to cement-based renders that aren’t integrally coloured.

Top Tips and Gotchas

  1. Don’t render in direct summer sun. Melbourne’s summer heat (35–42°C) dries render too fast, causing surface cracking. Apply render in the cool of morning, shade the wall if possible, and mist lightly during hot days.
  2. Wet the wall before rendering. Dry brickwork sucks moisture from fresh render and causes adhesion failure. Dampen the wall 2–3 hours before applying the scratch coat.
  3. Protect windows before starting. Masking film and tape around all windows and doors before rendering saves $200–$500 in glass cleaning time.
  4. Integrally coloured render saves money long-term. Paying extra for colour-in-render eliminates exterior repainting every 7–10 years ($2,000–$5,000/cycle on a full house).
  5. Check for asbestos first. Melbourne homes built before 1985 may have asbestos-containing materials in external cladding or eaves. Test before any removal or disturbance — a test costs $50–$150 per sample at an accredited lab.
  6. Expansion joints are mandatory on walls over 6m long. Renders without expansion joints crack along their natural stress lines within 5–10 years. Ask your renderer how they handle joint placement.
  7. Get a warranty in writing. Quality renderers offer 5–10 year workmanship warranties. Get this in writing with product specifications.
  8. Render curing takes 28 days before final paint. Wait the full cure time or paint adhesion is compromised — especially important in autumn and winter when temperatures are lower.
Safety warning: If your Melbourne home was built before 1985, fibro sheeting (asbestos cement) may be present in external cladding, eaves, or wall cavities. Never cut, sand, or disturb these materials without asbestos testing and professional removal. WorkSafe Victoria regulations require licensed asbestos removalists for areas over 10m².
Checking older Melbourne homes for asbestos before any rendering work
Checking older Melbourne homes for asbestos before any rendering work — pre-1985 homes commonly have asbestos fibro sheeting in eaves and cladding that requires professional removal before rendering can begin.

FAQ

How long does rendering a house last in Melbourne?

Quality acrylic render lasts 15–25 years in Melbourne’s climate. Cement render lasts 20–30 years if properly painted and maintained. The main enemies are cracking from reactive clay soil movement, water infiltration, and UV degradation of paint. Regular visual inspection and crack sealing every 5–7 years significantly extends render life.

Can you render over existing render?

You can render over existing render if the existing coat is sound, bonded, and crack-free. Test by tapping — hollow sounds indicate delamination that must be removed first. A renderer will typically apply a bonding primer before overcoating. Re-rendering over failed render just re-creates the same problems faster.

What’s the difference between rendering and plastering?

Rendering refers to external wall coating on masonry or brick. Plastering refers to internal wall finishing, typically on plasterboard (drywall) or fibrous plaster. The materials and techniques differ — exterior renders must withstand weather, UV, and moisture; interior plasters don’t. Both trades fall under the plasterer’s licence in Victoria.

Do I need council approval to render my house?

In most Melbourne residential zones, rerendering in the same or similar colour doesn’t require planning permission. Changing the colour significantly or rendering a heritage-listed home may require approval. Check with your local council — Cardinia, Casey, and Kingston Councils have online planning portals for quick checks.

How do I find a good renderer in Melbourne?

Ask neighbours for references, check Google reviews, and verify the plasterer’s licence at the Victorian Building Authority website. Get 3 written quotes specifying the render system (brand/product), number of coats, and surface preparation scope. Avoid any renderer who won’t specify the product or give a warranty.

Final Thoughts

Rendering a Melbourne home costs $4,000–$12,000 for a typical brick veneer house and adds significant kerb appeal and weather protection. The biggest investment you can make in a rendering job is surface preparation and product quality — cheap single-coat renders fail in 3–5 years, costing more in the long run than quality multi-coat systems. For older homes, check for asbestos before starting. Get 3 quotes, ask for product specifications, and insist on a written warranty.
