TL;DR: Before hiring a renovation builder, it’s important to ask the right questions to avoid costly mistakes, ensure quality work, and confirm they’re the right fit for your project. From experience and licences to timelines and communication, the answers you get will help you make a confident decision.
Key Takeaways:
- Ask about the builder’s licences, insurance, and past projects.
- Clarify timelines, costs, and how variations will be handled.
- Understand their approach to communication and project management.
- Request detailed written quotes to avoid budget blowouts.
Hiring the wrong renovation company can cost you time, money and sleep.
The right one will respect your budget, keep you informed, and deliver a finish you’re proud to show off.
If you are planning a bathroom, kitchen, laundry or whole‑home makeover in Melbourne, use these seven questions to separate true professionals from smooth talkers.
Take this article with you to every site visit. Ask the questions, listen carefully, and take notes. Good builders will welcome it.
1. Can I see a line‑item quote that matches a clear scope of works?
A one‑page “all‑up” price tells you very little. Ask for a written scope of works and a line‑item quote that lists materials, fixtures, labour, allowances and provisional sums.
This lets you compare apples with apples and understand where the money goes.
What a good answer sounds like
“We provide an itemised proposal with inclusions, exclusions and realistic allowances for PC items. You will know exactly what is covered before you sign.”
Red flags
- Vague lump‑sum pricing with no breakdown
- Lots of “TBC” notes or missing allowances
- Pressure to sign quickly to “lock in a discount”
Pro tip
Ask whether the quote includes demolition, rubbish removal, waterproofing, electrical, plumbing, tiling, painting and final clean. Small omissions add up fast.
2. What licenses, registrations and insurance do you hold, and can you share proof?
Your builder should be happy to share their registrations and certificates of currency for public liability and, where applicable, domestic building insurance for the job value.
In Victoria you should expect current registration with the Victorian Building Authority and membership with respected bodies.
What a good answer sounds like
“We are properly registered for domestic building work, we carry full public liability insurance, and we provide domestic building insurance for eligible projects.
Our memberships are current and on display in our proposal.”
Red flags
- “We work under someone else’s licence”
- Out‑of‑date or missing insurance paperwork
- Unwilling to provide certificate numbers you can verify
Pro tip
Keep digital copies of all documents. If anything changes mid‑project, ask for updated certificates.
3. Who will manage my project day to day, and how will you communicate?
Smooth projects have one accountable point of contact and a clear communication rhythm.
You should know who opens the site each morning, who schedules trades, and how you will receive updates.
What a good answer sounds like
“You’ll have a dedicated project manager. We run a weekly check‑in, share milestone updates and photos, and log variations in writing for approval.”
Red flags
- “Whoever is free will drop by”
- Only verbal updates
- No documented process for variations or changes
Pro tip
Ask to see an example weekly report or client portal screenshot before you commit.

4. What is the timeline from demolition to handover, and what could push it out?
Honest builders give you a realistic schedule and explain dependencies.
Weather, supplier delays and hidden issues behind walls can affect timing, but there should be allowances and contingency in the plan.
What a good answer sounds like
“For a standard bathroom, we typically schedule three to four weeks from demo to final clean, allowing float time for waterproofing and inspections. Your proposal includes a day‑by‑day outline.”
Red flags
- Promises that seem too quick
- No written program
- No mention of inspections, curing times or lead times on custom items
Pro tip
Ask when you need to have every selection finalised. Late tile or vanity choices push dates more than almost anything else.
5. How do you handle waterproofing, quality checks and compliance?
Bathrooms and wet zones fail when shortcuts are taken.
You want a methodical approach that follows Australian Standards, uses quality membranes, and documents each step.
What a good answer sounds like
“We use qualified waterproofers, install to AS 3740, and complete a wet‑area certificate. We photograph each stage and run a multi‑point quality checklist before handover.”
Red flags
- “Our tiler does a quick waterproof while he’s there”
- No mention of compliance certificates
- Shrugging off the need for moisture testing or flood tests
Pro tip
Request the brand of membrane, the number of coats, and curing times. Add this to the contract so there’s no guesswork.
6) What is excluded from the quote, and how are variations priced?
Clear exclusions protect both parties. Variations will happen, but they should be controlled.
You need to know the hourly rates, mark‑ups on materials, and approval process before work proceeds.
What a good answer sounds like
“Our proposal lists all exclusions in plain English. If a variation comes up, we issue a written variation with fixed or capped pricing. Work does not proceed without your signed approval.”
Red flags
- “We’ll sort it out along the way”
- Cash requests for extras
- Surprise invoices with no prior notice
Pro tip
Keep a small contingency in your budget, usually 10 to 15 percent. Use it only for genuine discoveries or upgrades you choose.
7) Can I speak with recent clients and see finished work similar to mine?
Photos are helpful, but there is no substitute for real feedback.
Ask for two or three recent references and, where possible, view a completed project or detailed case study that matches your scope and style.
What a good answer sounds like
“Here are three recent clients happy to take a call, and here is a gallery of projects with budgets, selections and before‑and‑after notes that are close to your brief.”
Red flags
- Only old references
- Stock images in place of real homes
- Reluctance to share addresses or contact details for privacy even after clients have agreed
Pro tip
When you speak to past clients, ask about cleanliness, punctuality, communication, how the team handled surprises, and if they would hire the same builder again.
Bonus checks most homeowners forget
Payment schedule sanity check
A fair payment schedule tracks real progress. Common milestones include deposit, completion of rough‑in, waterproofing, tiling, fit‑off and final clean. Avoid heavy deposits or front‑loaded schedules that do not match work done.
Site protection and safety
Ask how the team will protect floors, keep dust down and secure the site.
You should see drop sheets, dust extraction, temporary walls where needed, and a tidy site at day’s end.
Selections and lead times
Confirm who orders what, when orders are placed, and what happens if a product is discontinued.
A proactive builder will offer equivalent alternatives and get your approval in writing.
Warranty and aftercare
Get the length of workmanship warranty in writing, along with manufacturer warranties for fixtures and fittings.
Ask how to log a defect after handover and typical response times.
