If you’ve started collecting quotes, you’ve probably noticed they’re not apples-to-apples. Rendering is a bundle of steps — substrate prep, beading, base coats, finish coats, possible texture or colour, and clean-up — each nudging the price. And when you’re weighing how much to render a house, it helps to break those pieces out. It’ll give you context on scope and finish options specific to Sydney homes.
In short, you’re paying for:
Surface condition & prep: cracking, friable mortar, paint removal, or salt contamination mean extra labour.
Access & height: single vs double storey, roof overhangs, tight side setbacks, and whether scaffolding is required.
Render system: cement, polymer-modified, or acrylic systems priced per square metre, plus corner beads and mesh.
Finish type: smooth float, sponge, scratch, or textured coatings, with coloured finishes often priced higher.
As a homeowner, think in areas (m²) and complexity, not just “a house.” A 120 m² single-storey brick veneer often costs less per m² than a 120 m² double-storey with tricky access, even though the overall wall area may be similar.
Typical scope items that affect your quote (line-by-line)
When you read a rendering quote, look for these inclusions. If they’re missing, ask for clarification — it’s the fastest way to avoid surprise variations later.
Site prep & protection: masking windows, doors, and paths; temporary downpipe extensions; waste removal.
Substrate preparation: pressure washing, paint/efflorescence treatment, patching, and priming.
Beads & reinforcement: corner/stop beads, alkali-resistant mesh at stress points, control joints.
Coat schedule: base coat(s) + finish coat; texture or colour coat if specified.
Access: ladders vs scaffolding vs boom — and who pays.
Warranty & compliance: workmanship warranty, product data sheets, and (where relevant) adherence to NCC/NSW guidance. For a general masonry/render context, the Australian Government’s YourHome guidance on brickwork and blockwork is a handy reference for exterior finishes to walls: rendering a brick wall in Australia.
A practical way to estimate: Two real-world style examples
I’ll share how I’ve scoped costs in the past when comparing Sydney quotes — the method, not exact “market rates,” because those move with materials and demand.
Example 1: Single-storey brick veneer in the Inner West
When I priced my (hypothetical) three-bedroom brick veneer in Marrickville, I measured the external wall area: perimeter × wall height, minus windows and doors.
Area: ~160 m² of renderable surface after deductions.
Complexity: easy side access on one boundary, tight on the other; no second level; no major cracking.
System: cement render base with a smooth sponge finish, no colour coat.
What I found across three quotes:
Two contractors priced per m² and included corner beads, mesh at window heads, and full site protection.
One quoted a fixed lump sum, but excluded waste removal — a ~$300–$500 swing on a small job.
The most transparent quote broke out prep allowances (paint removal on one elevation) — which made the comparison fair.
Lesson: Per-m² numbers are helpful, but inclusions make or break value. A slightly higher per-m² figure with thorough prep often wins on longevity.
Example 2: Double-storey with awkward access in the Hills
For a friend’s two-storey brick-and-block place in Baulkham Hills:
Area: ~260 m² renderable surface.
Complexity: Narrow side setbacks, eaves overhangs, shrub pruning, and confirmed scaffolding requirement.
System: Acrylic finish over base coats for extra flexibility, with a fine texture.
Cement vs acrylic: Which system suits your home (and budget)?
Both have their place. A few rules of thumb I keep in mind when shortlisting systems:
Cement render
Familiar, durable, and cost-effective for large areas.
Heavier and more rigid, movement cracks on mixed substrates can appear if detailing is poor.
Needs paint or a texture/colour coat to finish.
Acrylic systems
More flexible and often more forgiving on hairline movement.
Typically specified with texture and/or colour coats, which can lift the look and reduce repainting cycles.
Materials cost more, but the finish is often smoother and more consistent.

Do you need approvals or special compliance checks?
Most straight-swap exterior finishes on houses (like render over clean masonry) are routine, but compliance still matters. NSW Government resources outline the contracting and consumer-protection settings for residential building work — helpful when you’re assessing staged payments, variations, and warranties. If you’re unsure about approvals or detailed standards for particular wall types or fire-performance contexts (e.g., multi-res or mixed-use), speak with your contractor and check current NSW guidance or the NCC notes from the ABCB.
How to read and compare quotes like a pro
When two quotes look similar, use this checklist to separate them:
Detail the prep. Ask how they’ll handle existing paint, efflorescence, or hairline cracks — and whether mesh and control joints are included.
Confirm the coat schedule. Base coats, finish coat, and any texture/colour coat — with product names.
Pin down access. Is scaffolding included? If not, what’s the allowance?
Ask for recent jobs. Drive-by addresses or photos of similar finishes help you judge quality.
Check warranty and aftercare. What fails are covered? How long is the finish expected to last before repainting or re-texturing?
If you’re weighing up repainting instead of rendering for budget reasons, consider an internal explainer that compares the two approaches in detail: painted brick vs render.
What a fair Sydney rendering proposal usually includes
From what I’ve seen on well-run Sydney projects, a tidy proposal will attach or reference:
Work description mapped to elevations, including prep notes.
Product system (manufacturer, coats, curing times, technical datasheets).
Programme with weather contingency.
Access plan (scaffold/boom) and site protection method.
Payment schedule & contract compliant with NSW requirements for residential building work.
When to choose a coloured texture coat
Coloured textures can cost more up-front, but they buy you a cleaner, more uniform finish and reduce early repainting. On mixed substrates, acrylic texture can help disguise transitions and dampen hairline cracking. If your home has heritage elements, check council guidance for exterior finishes on significant buildings; NSW heritage maintenance notes cover cleaning and finishes for masonry and render on older fabric.
Step-by-step: getting a reliable Sydney rendering quote
Measure your walls (roughly). Perimeter × wall height, minus windows/doors.
Photograph each elevation. Mark problem spots (cracking, salt, flaking paint).
Decide on the finish level. Smooth sponge vs textured vs coloured coat.
Ask for a like-for-like quote. Same scope, access assumptions, and coat schedule.
Request product datasheets and a recent local reference job.
Clarify the contract (deposit limits, progress payments, variations, warranties). NSW pages outline what must be in writing for residential building work.
Lock dates and site rules. Noise hours, parking, protection of paths and gardens.
Final Thoughts
Sydney rendering services aren’t a one-size-fits-all price; it’s a balance of area, access, substrate condition, and finish quality. Start with a clean scope, compare like-for-like quotes, and ask for product datasheets so you know exactly what’s going on your walls. If access or weather adds risk, call it out early. Do that, and you’ll get a sharper price, a smoother finish, and fewer surprises — the Sydney way: practical, tidy, and built to last.
