The short answer
Compare your quote with a sourced price range for the same job, then get at least two more written quotes with the same scope. A quote can look high because it includes more, so compare what is covered, not just the total.
Price ranges on this site are marketplace estimates with a source and a date. They are a way to sense check a quote, not a quote.
Step 1: write down the scope
List the rooms or area, the materials, the prep and who removes the rubbish. Use the same list for every quote.
Step 2: check a sourced range
Our cost guides show ranges with the source and the date checked:
- painting, plastering and fencing
- tiling, bathroom renovation and waterproofing
- concreting, decks and retaining walls
- plumbing, electrical and EV chargers
- carpentry and general building
Step 3: get two more written quotes
Consumer Affairs Victoria tells homeowners to compare at least three written quotes. Send each tradie the same brief.
Step 4: look for what is missing
A much lower quote often leaves something out, such as prep, waterproofing, materials or cleanup. Our guide on red flags shows what to look for.
Step 5: ask one good question
Ask the tradie with the highest price what is included that the others have not listed. Their answer tells you a lot.
