Decking in Ashby
Northern Decking Co repairs, restores and replaces decks in Ashby, a small City of Wanneroo suburb of mostly 2000s homes with land still to be developed. Work here is often bringing back a twenty-year-old timber deck or re-boarding it in composite. Every Wanneroo deck needs a building permit, and the contractor quotes free after seeing the site.

Decks that suit Ashby homes
Ashby is a small suburb: a late 1990s subdivision of Wanneroo, named in 1997, covering about one and a half square kilometres with 2,850 people at the 2021 census. Only around 40 percent of it has been developed for housing, so it has stayed small and quiet while the estates around it grew. The homes that are there mostly date from the 2000s, which puts their original decks at the age where the question is not whether to do something but what.
Twenty years of sun on a timber deck
A deck that went in with a 2000s home has had twenty-odd summers. The boards will be grey if they have not been oiled, some will have cupped or split, and screw heads will stand proud where the timber has shrunk around them. None of that means the deck is finished. The contractor looks under it first, at the stumps, bearers and joists, and if the frame is dry and sound the deck is brought back: soft boards out, the rest sanded and oiled, fixings replaced in stainless. Our deck repairs and restoration page explains how that call is made.
Re-boarding in composite
Where the boards are too far gone but the frame is fine, the alternative is to keep the frame and change the surface. Composite over an existing frame means extra joists to bring the centres in to what the board specifies, then hidden stainless clips and a picture-frame border. The deck looks new, the ground was never disturbed, and the upkeep drops to a hose. For an owner who has spent twenty years oiling, that is usually the point.
When it is a new deck
Some Ashby homes never had a deck, and some have one whose frame has rotted or been eaten. Either way it is a new build, and in the City of Wanneroo all decking requires a building permit, regardless of height or floor area. A low deck level with the alfresco is the common shape on a flat lot, in composite or hardwood, with the frame kept clear of the sand so it can breathe. Ashby is well inland, so salt air is not the design brief it is on the coast, and the hardware choice is about longevity rather than survival.
What the quote covers
Because every one of these jobs starts with a look at what is already there, the contractor quotes after a site visit and not before. Ask for the quote to separate the frame work from the boards so you can see where the money goes, and our guide to what affects decking cost sets out the factors before anyone arrives.
What to know before you build in Ashby
City of Wanneroo
- All decking requires a building permit, regardless of height or floor area.
- Planning approval may be required for decking over 500 mm above natural ground level.
- Decking over 500 mm is treated like a balcony, with a 7.5 m setback to side and rear boundaries unless a reduced setback is approved.
The ground
Coastal sand, as across most of the corridor. There is no suburb-specific ground record for Ashby, and the first footing hole confirms what the contractor expects.
Bushfire map
Check your lot on the DFES Map of Bush Fire Prone Areas. If it is inside a mapped area the deck is built to the BAL requirements of AS 3959. We do not say here whether Ashby is or is not bushfire prone, because the map runs through suburbs and is revised.
How it goes in
-
Footings
Stumps go into footings in the sand. Some sites in the far north hit limestone close to the surface and need core drilling.
-
Joists
Joists go across the bearers at the centres the board maker specifies, typically 450 mm for hardwood and tighter for composite.
-
Boards
Boards are laid from the house out with an even gap, fixed with screws or hidden clips.
Questions from Ashby
Can the deck on my 2000s Ashby home be restored rather than replaced?
Often, yes. The contractor checks the stumps, bearers and joists first. If they are sound, split and soft boards are replaced, the rest is sanded and oiled, and any corroded fixings are swapped for stainless. If the frame has rot or termite damage, restoration is spending money on a deck that has already gone, and the contractor says so.
Does a deck repair need a permit in Ashby?
In the City of Wanneroo all decking requires a building permit, regardless of height or floor area. Whether a repair that only swaps boards needs one is a question for the City, so confirm on 9405 5000 before work that touches the frame, and ask for the quote to say who lodges any application.
Can composite go on my existing timber frame?
Usually, if the frame is sound. Composite boards need closer joist centres than hardwood, so the contractor adds joists to bring the centres in, then fixes the boards with hidden stainless clips. The result is a deck that looks new and needs a hose rather than an oiling.
What decides the cost of a deck in Ashby?
Size, board, height, access and the state of any existing frame. A re-board on a sound frame is a smaller job than a new deck, and a raised deck is a bigger one than a low deck. The contractor quotes after seeing the site, and our guide on what affects decking cost explains each factor.
