Deckline Decks Ground-Level & Low Decks
A low deck is a tidy way to lift a dull slab or a patch of yard into an outdoor space, and the trick is what is underneath. We build low and ground-hugging decks with ventilation and the right bearer support so the underside breathes and dries, because timber down low that cannot dry is what rots. Over an existing slab or on new pads, usually with no balustrade and often no approval.
What this job includes.
- ✓Low and ground-level decks over an existing slab or new pads
- ✓Airflow and bearer support set up so the underside breathes
- ✓Slab falls and drainage checked before the deck goes over
- ✓The right grade timber or composite for ground proximity
- ✓Usually no balustrade and often no approval, confirmed on the quote
Priced by the m², itemised line by line.
The area in m² and the board and grade named, the footing depth and the bearer and joist spacing, the posts, the ledger flashing where the deck meets the house, the balustrade to the NCC, the stairs and any council approval. Not one round number for a deck.
- 1 Area in m², board and grade named. The price set by the m², with the board and its grade named: merbau or spotted gum, the composite brand, or H3 and H4 treated pine. Not one round number for "the deck".
- 2 The substructure, in full. The footing depth, the bearer and joist spacing, and the posts, sized for the height and the ground. This is the hidden frame that holds the deck up, and the line cowboys skip.
- 3 Ledger board and flashing to the house. Where the deck bolts to the house, the ledger board and its flashing, stated and detailed, because that join is what keeps water out of your wall.
- 4 Balustrade spec to the NCC. If the deck is over a metre up, the balustrade named to the NCC: timber, metal or glass, at least a metre high with gaps under 125 mm, so it passes rather than gets pulled up.
- 5 Stairs. Any stairs their own line: the rise, the run and the landing, built and balustraded to suit the height, not folded into a round number.
- 6 Council approval or CDC note. A plain note on which approval path the deck falls under, exempt, a Complying Development Certificate or a DA, so you know before we build, not after.
- 7 Warranty and finish. The 10-year footings, bearers and posts warranty in writing, the composite manufacturer warranty or the timber oil and coating, and how the finish is handled.
What happens, step by step.
Site measure and set-out
We measure the space, check the ground, the falls and the height, talk through board and balustrade, mark the set-out, then put a written by-the-m² quote in your hands.
Footings and posts
We dig and concrete the footings to depth, sized for the height and the ground, and set the posts plumb. The footings cure before any load goes on them. This is the substructure that holds the deck up.
Bearers and joists
The bearers and joists go on at the correct spacing for the board, closer together for composite, so the deck stays flat and never bounces. The frame is the deck; the boards are the finish.
Ledger and flashing
Where the deck meets the house we fix and flash the ledger board properly, so the join carries the load and keeps water out of your wall instead of bolting straight on.
Boards down
The boards go down at the right gap for drainage, screwed or hidden-fixed to the joists, raked and trimmed clean. Merbau, treated pine or the named composite, exactly as quoted.
Balustrade, stairs, oil and handover
We build the balustrade to the NCC and the stairs to suit the height, oil or finish the timber, clear the site, walk you around, and hand over the warranty and any compliance paperwork in writing.
The paperwork behind the price.
Public liability to $20M, and a 10-yr substructure warranty, all in writing, all on request.
Every deck is priced by the m², with the board and its grade named on the quote, the merbau or spotted gum, the composite brand, or H3 and H4 treated pine, and the substructure itemised: the footing depth, the bearer and joist spacing, the posts, and the ledger flashing where the deck meets the house. Any balustrade is built and named to the NCC. We hold a NSW Fair Trading building licence (000000C) and carry public liability insurance to $20M, and the guarantee is a 10-year written warranty on the footings, bearers and posts, the part that holds the deck up and the part cowboys skimp, plus the genuine composite manufacturer materials warranty where the boards are Trex, Modwood or Ekodeck. Deckline Decks is a composite reference site, so the licence number, ABN and contact details are illustrative placeholders, not a real operator; on a live build these are the real, verifiable credentials of the business.
Ground-Level & Low Decks: common questions.
Can you build a deck over my existing concrete slab or pavers?
Do low decks rot faster because they are close to the ground?
Do I need approval or a balustrade for a ground-level deck?
