Treated Pine Decks

Treated pine is the budget deck, and the value is in building the frame underneath properly. We concrete the footings to depth and space the joists right, using H4 where the timber meets the ground and H3 above, so the deck does not sag or rot out in two summers. The board grade is named on the quote, and it is priced honestly by the m².

Scope

What this job includes.

  • H3 and H4 treated pine decks, new and replacement
  • Footings concreted to depth, joists spaced to hold
  • H4 grade where the timber meets the ground, H3 above
  • Ready to stain or oil once it has weathered and dried
  • Old-deck removal and disposal itemised, never a surprise
Our system: H3 and H4 treated pine, the grade named in the right place on the quote, on concreted footings and correctly spaced joists, with the footings, bearers and posts warranted for 10 years.
How we quote it

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.

The 7-line quote
  1. 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. 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. 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. 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. 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. 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. 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.
If a quote doesn’t show these lines, you can’t compare it, and you don’t know what’s been cut.
How it runs

What happens, step by step.

1

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.

2

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.

3

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.

4

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.

5

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.

6

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.

Insured, covered, guaranteed

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.

The cover, the guarantee, and how to check each one.
Questions, answered

Treated Pine Decks: common questions.

How long does a treated pine deck last?
A well-built treated pine deck with concreted footings and correctly spaced joists typically lasts 10 to 15 years before the boards need real attention, longer if you keep it coated. Pine is the budget board, so the value is in building the frame underneath properly, which is exactly what we warrant. We will tell you honestly where pine suits you and where a hardwood or composite is worth the extra.
What is the difference between H3 and H4 treated pine?
It is the treatment level for where the timber sits. H3 is rated for above-ground outdoor use, the decking boards and rails; H4 is rated for in-ground contact, the posts that go into the dirt. We use the right grade in the right place, H4 where it meets the ground, so the frame does not rot out early. It is named on the quote.
Can a treated pine deck be stained or coloured?
Yes, once it has weathered and dried out enough to take a finish, usually a few months after the build. Pine takes stain and decking oil well and can be tinted to lift the colour or suit the house. We will tell you when it is ready and recommend a finish that holds up to the coastal sun.
