Start With a Clear Scope of Works Before Anyone Steps On Site
A scope of works is a written document that defines every task, material specification, and finish standard for your renovation. It covers which walls are being demolished, what fixtures and fittings are being installed, what tile size is going down, and who is responsible for procurement. The more specific it is, the fewer assumptions tradespeople make, and assumptions are where costs and conflicts are born.
| Scope Element | What to Include | Why It Matters |
|---|---|---|
| Demolition | What comes out, who removes waste | Avoids scope creep and disposal disputes |
| Structural changes | Wall removal, lintel requirements | Triggers permit obligations |
| Fixtures and fittings | Brand, model, colour, dimensions | Eliminates substitution without approval |
| Finishes | Tile size, grout colour, paint sheen | Sets a measurable workmanship standard |
| Procurement | Who supplies what, by when | Prevents delays caused by missing materials |
Define Your Budget Contingency Early
Most first-time renovators underestimate how frequently unexpected conditions appear once walls open up. Asbestos, substandard previous work, and concealed plumbing are common discoveries. Set aside a contingency reserve within your overall budget before any contracts are signed. Industry guidance generally recommends a contingency buffer for renovation projects, though the right figure depends on the age of your home, its construction type, and the complexity of work involved. Speak with your builder or project manager about what is realistic for your specific situation.
Obtain Building Permits Before Work Begins
Structural changes, electrical work, and plumbing alterations typically require building permits under the Building Act 1993 (Vic). Starting work without the required approvals can result in orders to demolish completed work, significant fines, and complications when you sell. Check with your local council or a registered building surveyor before any work begins. As the Victorian Building Authority’s guidance on building permits makes clear, the responsibility for obtaining permits rests with the owner or their nominated builder, not the subcontractors.
How to Find Reliable Tradespeople for Your Renovation
Start with referrals from people who have recently completed a similar renovation. A recommendation from someone whose bathroom or kitchen you have seen in person is worth far more than an online review. Ask specifically whether the tradesperson communicated well, stuck to the quoted price, and returned to fix anything that needed attention after completion.
Verify Licences and Insurance
Every licensed builder and tradesperson working on regulated work in Victoria must hold a current licence through the Victorian Building Authority. Electricians are licensed through Energy Safe Victoria, and plumbers through the Victorian Building Authority’s plumbing stream. You can verify a licence online before signing anything.
Insurance is equally non-negotiable. Confirm that your tradesperson holds:
- Public liability insurance (minimum $5 million is common for residential work)
- Workers compensation insurance if they employ others on site
- Domestic building insurance (required for work over the statutory threshold under the Domestic Building Contracts Act 1995 (Vic))
Ask for certificates of currency and check the expiry dates.
Hiring an unlicensed tradesperson for regulated work voids your domestic building insurance and leaves you personally liable for any injury or structural failure. The saving on the quote is never worth that exposure.
Get Written Quotes and Compare Them Properly
A written quote specifies the scope of works, the materials to be used, the price, the payment schedule, and the expected completion date. Comparing quotes on price alone is a trap. A quote that is significantly lower than others often excludes something you assumed was included.
When comparing quotes, align them against your scope of works line by line. Ask each tradesperson to confirm in writing what is and is not included. This process prevents the most common renovation dispute: “I didn’t think that was in my quote.”
According to the Consumer Affairs Victoria guide on building and renovating, homeowners should always get at least three written quotes for significant works and should never pay more than the deposit limits set under the Domestic Building Contracts Act.
The Order of Trades for Bathroom Renovation (and Other Wet Areas)
The order of trades for bathroom renovation follows a logic that, once you understand it, makes the whole project easier to manage. Get the sequence wrong and you will pay to have finished work damaged or redone.
The correct sequence for a standard bathroom renovation:
- Demolition, strip out all existing fixtures, tiles, and linings
- Rough-in plumbing, relocate or extend waste and water supply lines before walls close
- Rough-in electrical, install conduit, cables, and exhaust fan wiring before linings go up
- Waterproofing, apply membrane to wet area floors and walls; this must cure fully before tiling
- Tiling, floor and wall tiles laid once waterproofing is certified
- Fixing plumbing, install tapware, shower screens, vanity, and toilet
- Fixing electrical, install light fittings, exhaust fans, heated towel rails, and GPOs
- Painting and finishing, touch-up paint, silicone, and any carpentry trims
- Final inspection, compliance check and sign-off
The critical path is waterproofing. Tilers cannot start until the membrane has cured, and the membrane cannot go down until rough-in plumbing is signed off by a licensed plumber. Skipping or rushing this step is the most common cause of bathroom water damage claims.
Book your waterproofing inspection with your building surveyor before the tiler arrives. Inspectors are often booked several days out, and a delay here stalls every trade that follows.
Using Residential Building Contract Templates to Protect Yourself
A handshake agreement is not a contract. For any domestic building work over the threshold set by the Domestic Building Contracts Act 1995 (Vic), a written contract is legally required. Even for smaller jobs, a written agreement protects both parties.
Residential building contract templates should cover:
- The full scope of works (attached as a separate document)
- The total contract price and how variations are handled
- The payment schedule tied to milestones, not dates
- The start and expected completion date
- A defect liability period (typically 12 months for domestic work)
- Dispute resolution procedures
- Insurance obligations for both parties
The Master Builders Victoria contract resources and Consumer Affairs Victoria both offer guidance on what a compliant domestic building contract must contain. Do not use a generic template downloaded from a non-industry source without having it reviewed.
Progress payments should always be tied to completed milestones, not to calendar dates. Paying in advance of work being done removes your recourse if quality issues arise.
Managing Tradie Communication Day to Day
Most renovation disputes do not start with bad workmanship. They start with poor communication. A tradesperson who does not know what is expected, when they are needed, or who to contact when a problem arises will fill those gaps with their own assumptions.
You are, in effect, running a small project management operation. You need a single source of truth for the schedule, a clear decision-making process, and a record of every instruction given.
Digital Tools That Keep Everyone Accountable
Project management tools designed for residential construction can dramatically reduce the communication overhead of managing multiple trades. A shared project timeline, accessible to all trades, removes the “I didn’t know the plumber was coming today” excuse. Look for tools that allow you to:
- Publish and update the renovation schedule in real time
- Log site notes and decisions with timestamps
- Share photos of completed work for remote review
- Track progress payments against milestones
Even a shared folder with a running decision log, dated photos, and the signed scope of works is better than managing everything through text messages.
Every instruction or variation agreed verbally should be confirmed in writing the same day. A short message saying “confirming we agreed to move the vanity 200mm to the left at a cost of $X” creates a paper trail that protects everyone.
Managing Trades Remotely or Off-Site
Managing a renovation from a distance is harder, but manageable with the right systems. Appoint a single on-site contact, whether a licensed builder acting as principal contractor or a trusted project manager, who has authority to make day-to-day decisions within agreed parameters.
Daily photo updates from site, a shared schedule with milestone sign-offs, and weekly video calls with your on-site contact are the minimum viable communication structure for remote management. Agree in advance which decisions require your sign-off and which can be made on site.
WDC Services manages the full project coordination process for clients, including on-site supervision across trades, so homeowners do not need to be present for every decision.
How to Manage Renovation Trades When Disputes Arise
Disputes happen. The question is whether you have the contractual and documentary foundation to resolve them efficiently.
The most common disputes involve scope creep, defective workmanship, and payment disagreements. Each is significantly easier to resolve when you have a written contract, a detailed scope of works, and a contemporaneous record of instructions.
The first step in any dispute is direct conversation. Most issues can be resolved by calmly referring to the written agreement and agreeing on a path forward. If direct resolution fails, the Domestic Building Contracts Act 1995 (Vic) establishes a formal dispute resolution process through the Victorian Civil and Administrative Tribunal (VCAT). Domestic building disputes can also be referred to Domestic Building Dispute Resolution Victoria (DBDRV) before escalating to VCAT, which is a faster and lower-cost process for many common disputes.
Document everything before, during, and after any dispute conversation. Photographs of defective work, written records of instructions, and copies of all correspondence are your evidence.
Post-Renovation Handover: Defect Lists and Quality Assurance
A defect list is a written record of items that do not meet the contracted standard at the point of handover. It is not a criticism of the tradesperson’s work; it is a professional mechanism for ensuring contractual obligations are met before final payment is released.
Walk through the completed renovation with your builder or project manager and check every item against the scope of works. Common defect list items include:
- Grout lines that are inconsistent or not fully filled
- Silicone beads that are uneven or have gaps
- Paint touch-ups missed on trims and reveals
- Tapware that is not fully seated or leaks under pressure
- Exhaust fans that are not functioning or not connected to the correct circuit
- Tile lippage that exceeds the standard specified in AS 3958.1
A defect liability period, typically 12 months for domestic building work, gives you the right to have defects that appear after handover rectified by the builder at no cost. Make sure this period is written into your contract and that you know the process for notifying defects in writing.
Keep all warranties for fixtures and fittings, compliance certificates for electrical and plumbing work, and the waterproofing certificate. These documents are required when you sell the property and are essential if a defect claim arises later.
Managing renovation trades well is about setting clear expectations, getting the right agreements in writing, sequencing work correctly, and maintaining communication that leaves no room for misunderstanding. The homeowners who have the smoothest renovations are not the ones who are on site every day; they are the ones who did the planning work before anyone picked up a tool.
If you would rather not carry that coordination burden yourself, WDC Services offers full project management from initial design through to handover, integrating carpentry, waterproofing, tiling, electrical, and fit-out under a single managed process.

Frequently Asked Questions
What is the standard order of trades for a home renovation?
The general sequence runs from structural and rough-in work through to finishes. Demolition comes first, followed by any structural changes, then plumbing and electrical rough-ins, waterproofing, plastering, tiling, cabinetry, and finally fixtures and fittings. The critical path shifts slightly by room, a bathroom renovation, for example, requires waterproofing sign-off before tiling can begin. Skipping or overlapping trades in the wrong order creates rework, delays, and potential compliance issues under the National Construction Code.
How do I ensure my renovation trades are licensed and insured?
Each state and territory has its own licensing body. In Victoria, check a tradesperson’s registration through the Victorian Building Authority (VBA) before signing anything. Ask for their licence number and verify it online. Confirm they hold current public liability insurance and, where applicable, domestic building insurance. Licensed builder status is required for residential building work valued above the threshold set in the Domestic Building Contracts Act 1995 (Vic). Never rely on a verbal assurance, request copies of both documents.
What should be included in a contract with a renovation tradie?
A solid residential building contract should cover the full scope of works, agreed start and completion dates, a payment schedule tied to milestones rather than arbitrary dates, a variation clause explaining how changes are priced and approved in writing, and the defect liability period. Consumer Affairs Victoria provides residential building contract templates as a starting point. Avoid contracts that request large upfront deposits, progress payments tied to completed stages protect both parties and reduce the risk of a tradie disappearing mid-project.
How do I manage a renovation budget when hiring multiple trades?
Set your total budget before seeking quotes, then allocate amounts per trade category and hold back at least 10-15% as a contingency for variations and emergency repairs. Collect written quotes from at least three tradespeople per trade, comparing scope rather than just the bottom line. Track all approved variations in writing and update your budget tracker immediately. Milestone-based progress payments help you monitor spend against completed work, making it far easier to spot cost blowouts before they compound.
