Choosing a Renovation Contractor Melbourne: 12 Essential Tips to Hire the Right Expert

Hiring the wrong renovation contractor doesn’t just cost you money. It costs you weekends, patience, and the ability to walk into your own kitchen without wincing. If you’re serious about choosing a renovation contractor in Melbourne, this guide walks you through exactly what to check before you sign anything.

Whether you’re renovating a bathroom in Berwick or planning a full home makeover in Cranbourne, the same principles apply. Good renovations start with a good contractor, not a good sales pitch. Here are 12 tips that separate the two.

Credentials and Experience

1. Verify Their Licence and Registration

Before you discuss anything else, check that your contractor is a registered building practitioner. In Victoria, licensed builders and plumbers now sit under the Building and Plumbing Commission (BPC), which took over building and plumbing regulation on 1 July 2025 after replacing the former Victorian Building Authority (VBA). An unlicensed contractor might quote you a lower price, but you lose insurance protection and legal recourse if something goes wrong.

2. Check Renovation-Specific Experience

A contractor who builds new homes all day isn’t automatically great at renovations. Renovation work involves existing structures, hidden plumbing, and surprises behind the walls that new builds simply don’t have. Ask directly: “How many bathroom or kitchen renovations have you completed in the last two years?” A confident answer is a good sign. A vague one isn’t.

3. Review Their Portfolio and Past Projects

Photos tell you more than a sales conversation ever will. Look for finish quality, tile alignment, and whether the “after” photos actually match the scale of your project. If a contractor mainly shows small patch-up jobs and you’re planning a full renovation, that’s a mismatch worth noting.

4. Read Customer Reviews and Testimonials

Check Google reviews, Facebook, and any third-party platforms before you rely on testimonials on the contractor’s own website. A handful of five-star reviews posted the same week is worth a second look. Genuine reviews tend to be detailed, specific, and a little messy, just like real renovations.

Quotes, Pricing and Contracts

5. Always Compare Multiple Quotes

Two or three quotes give you a realistic price range and expose contractors who are quoting well above or suspiciously below the market. Make sure each quote covers the same scope of work. Comparing a full renovation quote against a “supply only” quote isn’t really comparing anything.

6. Insist on a Fixed-Price, Itemised Quote

A proper quote breaks down labour, materials, and any allowances separately, so you know exactly where your money goes. Vague, one-line quotes (“bathroom renovation: $X”) leave too much room for disputes later. Ask for itemisation before you commit, not after.

7. Understand the Contract Before You Sign

Consumer Affairs Victoria requires a written contract for most domestic building work above a set value, and for good reason: verbal agreements are hard to enforce when a dispute shows up. Before signing, check the contract clearly states the scope of work, payment schedule, start and completion dates, and how variation costs (changes to the original scope) are handled.

What a solid renovation contract should include:

Communication and Project Management

8. Ask Who Will Manage the Project Day-to-Day

Some renovation companies assign one project manager as your single point of contact. Others rely on a rotating cast of subcontractors with no one really in charge. Ask this question early, because chasing five different tradespeople for updates gets old fast.

9. Clarify the Renovation Timeline Upfront

Ask how long your specific project will take, what could realistically delay it, and how you’ll be updated if it does. Materials lead times and trade availability affect almost every renovation in Melbourne, so a contractor who promises zero delays is either lucky or not being straight with you.

Insurance, Compliance and Protection

10. Confirm Insurance Coverage

Ask for proof of public liability insurance, which covers property damage or injury during the project. For larger jobs, domestic building insurance may also apply under Victorian law. Never take “yes, we’re insured” as a complete answer. Ask to see the certificate.

11. Check Building Permit and Compliance Responsibilities

Clarify upfront who is responsible for building permits and council approvals, and confirm this is written into the contract rather than assumed. Since the Building and Plumbing Commission became Victoria’s building regulator, homeowners should confirm a contractor’s current registration status directly with the BPC rather than relying on older VBA references. For a full breakdown of when permits are actually required, see our guide to renovation permits in Victoria.

12. Ask About Warranty and After-Service Support

A workmanship guarantee tells you a contractor stands behind their own work. Ask how long the guarantee lasts and exactly what it covers, whether that’s tiling, waterproofing, or fixtures. If a contractor gets defensive about this question, treat it as useful information in itself.

Red Flags to Watch For

A few warning signs tend to show up again and again with unreliable contractors:

• No written contract, or reluctance to provide one
• Pressure to pay the full amount upfront
• No fixed business address or ABN you can verify
• Quotes given verbally with nothing in writing
• No proof of insurance when asked directly

One red flag might be an oversight. Two or more, and it’s time to keep looking.
