A deck lives or dies on what you cannot see: the footings, framing and fixings under the boards. A cheap quote often means a lighter substructure that fails sooner, so who builds it matters as much as the timber you pick.
This guide covers what to check, what to ask, and the warning signs to avoid, so you can compare Adelaide deck builders with confidence.
What to Look For
Questions to Ask Before You Sign
1.What footing type and depth are you allowing for my ground conditions?
2.How will the deck attach to the house, and how is that waterproofed?
3.Are compliant balustrade and steps included in this price?
4.What timber or composite grade is quoted, and what warranty applies?
5.What is the deposit, and how is the rest staged?
6.Do I need council approval, and will you handle it?
Red Flags to Walk Away From
Common Questions
Check the builder is licensed and insured, then compare at least three itemised quotes that spell out the substructure, footings and fixings, not just the boards. Ask about footing depth for your ground, how the deck attaches to the house, whether balustrade and steps are included, and the workmanship warranty. Good Adelaide deck builders explain the substructure clearly and put the full scope in writing. Be cautious of quotes that only price the decking surface.
