Choosing a concrete contractor is not only about finding the lowest quote. The quality of the site preparation, concrete mix, reinforcement, drainage, finishing and curing can affect how the finished surface looks and performs.
For homeowners, builders, property managers and commercial property owners, the right contractor should offer clear advice, a detailed scope of work and proof that they can complete the job safely.
This guide explains what concrete contractors do, the residential services they provide and the checks you should make before hiring a contractor in Perth.
What Does a Concrete Contractor Do?
A concrete contractor plans, prepares, pours and finishes concrete surfaces. Their work may include driveways, pathways, patios, pool surrounds, shed slabs, garage slabs and decorative concrete.
A professional concreting project usually includes:
- Inspecting and measuring the site
- Checking access, ground conditions and drainage
- Removing existing concrete or soil when required
- Preparing and compacting the base
- Installing formwork and reinforcement
- Ordering and placing the specified concrete
- Creating falls, joints and the selected surface finish
- Curing the concrete and protecting it while it gains strength
- Cleaning the work area and completing a final inspection
The Guide to Concrete Construction from Cement Concrete & Aggregates Australia covers concrete materials, specification, placement and performance. It shows why the completed surface is only one part of a sound concreting job.
Residential Concrete Services in Perth
Concrete contractors may offer several services. Ask whether the contractor has recent experience with the type of project you need.
Concrete driveways and crossovers
A driveway must handle vehicle traffic while directing water away from the house and other structures. The quote should explain the excavation, base preparation, slab thickness, reinforcement, surface finish, joints and drainage included in the work.
The section between a property boundary and the road is normally called a crossover. Approval rules differ between councils. For example, the City of Perth requires crossover approval before that work starts.
Pathways and entrance areas
Concrete paths can provide clean, low-maintenance access around a property. The layout should account for doors, garden beds, gates, downpipes and natural water flow. Discuss the proposed width, falls, finish and connection points during the site visit.
Patios and outdoor entertaining areas
A patio needs a practical layout and a finish suited to outdoor use. Planning may include furniture locations, steps, nearby landscaping, drainage and links to the house. Decorative choices include coloured concrete, exposed aggregate and honed finishes.
Pool surrounds
Pool surrounds need careful set-out and drainage. Ask how the new work will meet the pool edge, fences, gates and nearby paving. Surface texture and ongoing care should also be discussed before selecting a finish.
Shed and garage slabs
Slab requirements depend on the structure and its intended loads. The contractor should work from the relevant plans or specifications and confirm the earthworks, base, formwork, reinforcement and concrete included in the quote.
Decorative concrete
Decorative concrete can change the colour and texture of an outdoor area. Common choices include exposed aggregate, coloured concrete, honed concrete and sealed finishes. View completed projects in person where possible, because online photographs may not show the exact colour or texture.
Concrete removal and replacement
Badly cracked, sunken or poorly drained concrete may need removal. Ask how the old material will be taken away, how the cause of the damage will be checked and how the replacement area will connect with existing surfaces.
Why the Right Concrete Contractor Matters
Concrete hardens into a permanent surface, so errors can be costly to repair. A good-looking finish will not correct a weak base, poor drainage or unsuitable joint placement.
An experienced contractor should be able to explain:
- How the ground will be excavated and compacted
- Which base material will be used
- How water will move across and away from the slab
- What concrete specification is proposed
- Where reinforcement and joints will be placed
- Which finish suits the area
- How the concrete will be cured
- When people and vehicles can use the surface
Clear answers do not guarantee a problem-free project, but they help you compare contractors using the same project requirements.
15 Checks Before Hiring Concrete Contractors in Perth
1. Confirm the contractor’s business details
Ask for the legal business name, ABN, contact details and business address. Check that the name on the quote matches the person or company taking responsibility for the work.
2. Check whether builder registration applies
Not every small concreting job has the same registration requirements. In WA, builder registration can apply when work requires a building permit and passes set value thresholds. The WA Government builder registration guide explains the current rules.
If registration applies, search the relevant public register and check that the details are current.
3. Ask for proof of insurance
Request a current certificate of currency for public liability insurance. Depending on the job, other insurance or workers compensation cover may also be relevant. Check the insured name, policy period and level of cover.
4. Review similar completed projects
Ask to see recent driveways, patios, paths or slabs similar to your project. Look at the edges, drainage, surface consistency, joints and how the concrete meets other areas.
5. Speak with recent customers
Ask whether the contractor can provide references. Useful questions include:
- Did the work start and finish close to the agreed dates?
- Were changes explained before extra work began?
- Was the final price consistent with the agreed scope?
- Was the site left clean?
- How did the contractor respond to any problems?
6. Request an on-site inspection
A site visit lets the contractor check measurements, access, levels, soil, demolition needs and drainage. It also gives you a chance to ask how the work will be carried out.
7. Get a detailed written quote
The quote should identify what is included and excluded. Ask for details covering:
- Total area and measurements
- Removal and disposal of existing material
- Excavation depth and base preparation
- Formwork and reinforcement
- Concrete specification and proposed thickness
- Surface finish, colour and sealer
- Drainage and falls
- Joint locations
- Permit or council fees
- Site access and protection
- Cleanup and waste removal
- Payment stages
- Warranty or defect process
8. Compare the scope, not only the total
Two quotes may describe very different jobs. One may include removal, extra base preparation, reinforcement or sealing while another leaves those items out. Compare every line before deciding which proposal offers better value.
9. Ask who will complete the work
Find out whether the person quoting the project will be on site and whether subcontractors will be used. Ask who will supervise the work and who you should contact during the project.
10. Confirm permits and council approvals
Permit needs depend on the project and local government area. WA Building and Energy advises property owners to contact their local government about application requirements and local laws. See the WA building approvals guidance.
The written scope should state who will apply, supply drawings and pay fees.
11. Discuss site preparation
Ask the contractor to explain how much material will be removed, how the subgrade will be checked and how the base will be compacted. If soft ground, tree roots, old fill or poor drainage is found, ask how any extra work will be priced and approved.
12. Ask about reinforcement and joints
The contractor should explain the proposed reinforcement and joint layout. These details should suit the slab’s use, dimensions and design requirements. Avoid treating reinforcement or joints as a one-size-fits-all item.
13. Check the silica-dust controls
Cutting, drilling or grinding concrete can release respirable crystalline silica. Safe Work Australia states that concrete can contain crystalline silica and that processing it can create hazardous dust.
Ask how the contractor will control dust, protect people nearby and clean the site. Wet methods, suitable extraction and correct protective equipment may form part of the work method.
14. Put payment stages and changes in writing
Do not rely on verbal promises. The contract should set out the price, payment stages, scope and process for changes.
For home-building contracts covered by WA law, contracts must be written and signed, deposits are restricted, and progress payments must relate to work already completed. Current details are available in the WA Government guide for building or renovating a home.
WA guidance also states that covered contract changes must be written, dated and signed before the changed work begins. See the obligations for registered building service providers.
15. Complete a final inspection
Walk through the project before the final payment. Check the completed area against the written scope. Record any agreed corrections in writing and keep copies of the quote, contract, variations, invoices, permits and care instructions.
Questions to Ask During the Site Visit
Take these questions to each appointment:
- What site preparation does this project need?
- How will you manage drainage and surface falls?
- What concrete specification and slab thickness do you propose?
- What reinforcement will be used?
- Where will the joints be placed?
- Which finish best suits this area and how should it be maintained?
- Do I need a permit or crossover approval?
- Who will arrange approvals and inspections?
- How will you manage dust, noise and access?
- What could cause the price or schedule to change?
- How will changes be approved?
- What curing process will be used?
- When can the area take foot or vehicle traffic?
- What warranty or defect terms are included?
- Who will supervise the project?
Warning Signs When Comparing Contractors
Be cautious when a contractor:
- Refuses to provide a written quote
- Will not supply business or insurance details
- Cannot explain the preparation work
- Gives no details about drainage, reinforcement or joints
- Requests a payment structure that does not match applicable WA rules
- Pushes you to approve the job immediately
- Wants changes agreed only by phone
- Offers no recent project examples
- Gives unclear warranty terms
- Provides a price far below other quotes without explaining why
A low price may be genuine, but you should know whether materials, preparation or cleanup have been removed from the scope.
How Much Does Residential Concreting Cost in Perth?
There is no reliable single price for all Perth concreting projects. The final quote can change based on:
- Total area and concrete volume
- Site access
- Demolition and disposal
- Excavation and base preparation
- Ground conditions
- Reinforcement
- Concrete specification
- Surface finish and colour
- Pumping or special equipment
- Drainage work
- Steps, curves and detailed formwork
- Council applications or permits
- Sealing and aftercare
Ask at least two or three contractors to quote the same written scope. This makes it easier to identify missing items and understand large price differences.
Perth Permits, Contracts and Local Requirements
Building permits and local rules
Your local government assesses building permit applications and can explain local requirements. Never assume that approval in one Perth council area means the same rule applies in another.
Driveway crossover approval
A crossover connects private property with the road through the verge. Councils may set requirements for width, location, levels, nearby trees and public infrastructure. Confirm approval needs before booking the pour.
Written contracts and payments
WA’s Home Building Contracts Act protections apply to certain residential work. Government guidance states that covered contracts from $7,500 to $500,000 must be written and signed. It also states that the maximum deposit is 6.5% and that progress payments must cover work performed. Check the latest rules for your project before signing.
Home indemnity insurance
Home indemnity insurance may be required for residential building work that needs a building permit and is valued above $20,000. Some associated work has different treatment. The WA Government homeowner guide explains when the cover may apply and what certificate the builder must provide.
These rules depend on the type, value and approval status of the work. Seek guidance from WA Building and Energy or your local council if you are unsure.
Concrete Finish Options for Perth Properties
Plain concrete
Plain concrete offers a simple finish for utility areas, paths and some driveways. Ask whether the surface texture and appearance suit the location.
Coloured concrete
Colour can help the surface match a home or landscape design. Ask to view physical samples and completed work, as colour can look different under changing light.
Exposed aggregate
Exposed aggregate reveals selected stones at the surface. Aggregate choice, exposure level, sealing and workmanship all affect the final appearance.
Honed concrete
Honing creates a smoother decorative finish by grinding the surface. Ask where the contractor recommends using it and what care it needs.
Sealed decorative concrete
A sealer can change appearance and maintenance needs. Ask about the product, finish, reapplication schedule and care instructions before the job begins.
Why Local Perth Experience Helps
A contractor with recent Perth experience should understand local council processes, common site-access issues and the planning needed for outdoor concrete work. Local experience can also help when coordinating material supply, equipment and project timing.
Do not rely on the word “local” alone. Ask for recent projects, clear documentation and direct answers about your site.

Frequently Asked Questions
1. How do I choose a reliable concrete contractor in Perth?
Check the contractor’s business details, relevant registration, insurance, recent work and customer references. Request an on-site inspection and a detailed written scope covering preparation, concrete, reinforcement, joints, drainage, finish, payments and warranty terms. The WA Government registration guide explains when registered building contractors are required.
2. What should a concrete quote include?
A strong quote should list measurements, demolition, excavation, base preparation, reinforcement, concrete specifications, finish, drainage, joints, approvals, waste removal, payment stages and warranty terms. It should also show exclusions and explain how extra work will be approved.
3. Do I need council approval for a concrete driveway in Perth?
Approval depends on the work and local council. A crossover on council-controlled land often needs approval. The City of Perth, for example, requires approval before crossover work starts. Contact the council responsible for your property for the rules that apply there.
4. How long should new concrete cure before it is used?
The required waiting time depends on the concrete, weather, slab design and intended use. Foot traffic and vehicle traffic may have different timeframes. Follow the contractor’s written instructions and do not use the surface early. CCAA provides a dedicated concrete curing data sheet explaining why curing affects concrete quality.
5. What payment rules apply to concrete work in WA?
The answer depends on the type and value of the contract. For home-building contracts covered by WA law, government guidance states that deposits cannot exceed 6.5% and progress payments must relate to completed work or supplied materials. Review the current WA contract guidance before signing.
