Treated pine and hardwood timber fencing in Seaforth — paling, lapped and capped, picket and horizontal slat, built to last.
Fencing and Landscaping Experts provide timber fencing throughout Seaforth, NSW 2092, in Northern Beaches Council's area on the Northern Beaches. The ground here is sandstone shelf close to the surface, so posts are frequently drilled and chemically anchored into sandstone rather than concreted into a dug hole. For timber fencing in Seaforth, posts are H4 treated pine, rated for in-ground use. Per lineal metre supplied and installed, after a free on-site measure. Licensed in NSW, insured to $20 million.

We work on timber fencing throughout Seaforth 2092, where the service covers treated pine palings, hardwood, lapped-and-capped, pickets and horizontal slat screens. With large homes on steep blocks with terraced gardens and long driveways, no two streets in Seaforth present the same problem.
Timber lives or dies at the ground line. We use H4-treated posts rated for in-ground use, concrete them properly, and keep palings clear of the soil so moisture cannot wick up into the end grain. Timber holds up better than cheap steel in salt air, but coastal fixings still matter — we use hot-dip galvanised or stainless fasteners near the beach because standard bright fixings bleed rust down a new fence within a season. Seaforth sits back from the open surf, so the coastal grade matters most on the exposed elevations rather than over every metre of the job. Access is a genuine cost factor in Seaforth — where materials have to be carried down a stepped side path or worked off a slope rather than delivered straight to the work, the labour component rises.
The ground under Seaforth is steep sandstone falling to Middle Harbour, with rock shelf close to the surface, and the suburb is built out with large homes on steep blocks with terraced gardens and long driveways. Those two facts decide footing depth, material choice and how long the job takes, so we measure on site before we price anything in Northern Beaches Council's area.

We work across Seaforth and the surrounding Northern Beaches suburbs, and the local conditions genuinely change the job. On the Northern Beaches, salt is the enemy. Airborne chloride from the ocean strips standard galvanising and eats fixings, so material grade matters more here than anywhere else in Sydney — and with pools on a large share of blocks, compliant pool fencing is constant work.
For timber fencing specifically, the constraints that come up most often in Seaforth are coastal salt exposure, sand and dune soils near the beach, and strict pool barrier compliance. Northern Beaches Council is the consent authority for Seaforth, so where approval is needed that is the path we work through with you — and we identify that before quoting rather than halfway through the job.
A properly built treated pine fence in Seaforth gives 15 to 20 years, and hardwood longer. What shortens it is almost always the same thing — posts that were not H4 rated for in-ground use, or footings that let water sit around the post. Sandstone sits close to the surface across much of Seaforth, so posts are often drilled into rock and chemically anchored rather than concreted into a dug hole.
Treated pine is the sensible default: it is cost effective, readily available and performs well when installed correctly. Hardwood costs more but resists impact and weathering better, and looks better if you intend to leave it unpainted. For most Seaforth boundaries treated pine palings on hardwood or H4 pine posts is the right balance.
Yes, and it should be if you want it to last. Sealing a Seaforth timber fence slows moisture movement in and out of the boards, which is what causes cupping and splitting. We can supply pre-primed material or finish on site once the timber has dried out.
Seaforth blocks fall enough that a level fence line is rarely the right answer. We step the panels down the fall in short runs, or rake the panels to follow the ground where the style allows. Where the level change across the boundary is large, a low retaining wall with the fence built above it is usually the better solution.
Yes. Timber performs well across Seaforth provided the posts are H4 rated for in-ground use and properly concreted. The main thing to check is whether your block is mapped as bushfire prone, which would change the recommendation near a bushland boundary.
All of Seaforth 2092, plus the surrounding streets in Balgowlah, Fairlight, Manly Vale, Clontarf and Killarney Heights. Seaforth is characterised by large homes on steep blocks with terraced gardens and long driveways, and we schedule around what that means on the ground rather than booking a standard slot. We give you a firm start date with the quote rather than an open-ended window.
