Decking, supply + install
Treated pine, composite or jarrah over engineered joists. Every board gauged, every fixing hidden where the timber allows.
From $340/m² · 6 m² minimum billed · new decks from $2,040
Osborne Park workshop · crews metro-wide
Carpentry & decking across Perth — measured twice, built once.
Jarrahline builds decks that stay square and hangs doors that finally close. Size your deck below — timber, balustrade and price settle on the page before you ring.
Est. 2011 · every deck handed over oiled, swept and square
Priced from the tape, not the brochure. Decking is $340–$560 a square metre supplied and installed, by timber — the planner does the arithmetic in the open.
Small jobs welcome. Doors from $160 hung, skirting from $14 a lineal metre — the ute carries more than decking boards.

Kwila posts and stainless wire, $290 a lineal metre — balustrade prices the same over any deck timber.
Decking — treated pine, 12.0 m² × $340$4,080
Billed at the 6 m² minimum — a small deck still takes a day's setup, so anything under 6 m² bills as 6 m² at your timber's rate.
Balustrade — 4.0 lm × $290$1,160
Old-deck demolition & removal — 12.0 m² × $48$576
Estimate$4,080
Demolition bills the drawn area — the 6 m² minimum applies to the decking line only. Demo estimate, supply + install; we'd confirm every figure on a site measure.

Reviews
Word of mouth, written down
★★★★★
"The deck went down in late November and survived an Australia Day party of forty-three people, two eskies and a borrowed jukebox. Not a board has moved."
★★★★★
"Seventeen internal doors. Every one of them stuck, scraped or swung open on its own. Two days later they all close with that soft click you get in display homes."
★★★★★
"We asked for a balustrade that wouldn't block the pool from the kitchen window. From the sink you honestly can't see the wire — just the deck and the water."

FAQ
Asked at every site measure
Treated pine, composite or jarrah — what's the honest difference?
Pine is the budget workhorse: takes stain well, needs oiling, dents easier — $340/m² installed. Composite costs more up front ($480/m²), never needs oil and won't splinter, but it can't be sanded back and reads slightly flat next to real timber. Jarrah ($560/m²) is the premium: dense, deep red, ages to silver if you let it — the deck people put their hand on. There's no wrong answer, only a right one for your budget and your appetite for maintenance.
Does a deck need council approval?
Usually not: most low freestanding decks under 500 mm off the ground are exempt development in WA. Anything higher, attached to the house, or near a boundary can need approval — rules differ by council, so check yours. We flag it at the site measure and won't build what would need to come down.
How long does a 12 m² deck take?
Two to three days once materials are on site: day one is footings and joists, day two is boards, day three is trim, oil and cleanup. Weather and access can stretch it — we tell you before it does.
Can you do the framing only, if I want to lay the boards myself?
Happily — plenty of handy owners lay their own boards on our frame. Framing-only work is quoted from your site and drawings rather than priced in the planner, because footings and levels vary too much for a fair flat rate.
When should I re-oil the deck?
Hardwood decks want oil every 12–18 months in Perth sun — sooner if it faces west. Pine similar; composite never. Quick test: drip water on a board. If it soaks in instead of beading, it's time. Every new Jarrahline deck is handed over with its first coat done.
