Auckland deck replacement

Deck replacement – old deck out, substructure sorted, new deck built to last

Decks do not usually fail all at once. A board goes soft, a nail lifts, the handrail gets some give, then one winter a joist lets go. We check what the deck is built on – the piles, bearers and joists – before we quote, because laying new boards over a rotten frame just buys you the same problem in a few years.

    Choosing decking

    What decking is right for the job?

    The right board comes down to budget and how much upkeep you want – but whatever goes on top, the frame underneath has to be sound. We check the piles, posts, bearers and joists for rot, movement and failed timber before we lay a single board, and if the substructure needs work we tell you up front and price it in.

    01

    Treated pine

    The most affordable way to get a solid new deck down. H3.2 treated pine is designed for outdoor use, takes stain or oil well, and suits a budget-conscious replacement or a rental where you want a sound, safe deck without the hardwood price tag. It needs oiling every year or two to hold its colour, and we can set it up to make that easy.

    02

    Kwila & hardwood

    The classic Auckland deck look. Kwila and vitex are dense, hard-wearing hardwoods with a rich grain that handle heavy foot traffic and weather well when looked after. This is the pick when you want a deck that looks the part off your living areas. Kwila bleeds tannin early on, so we let you know what to expect and how to manage it near light paving.

    03

    Composite

    The low-maintenance option. Composite boards like Ekodeck do not need oiling, will not splinter, and hold their colour without the yearly upkeep of timber – which makes them popular for busy households and landlords who want to set and forget. It costs more up front than pine, but you trade that against years of not sanding and coating.

    04

    Substructure check & repair

    Whatever goes on top, the frame underneath has to be sound. We check the piles, posts, bearers and joists for rot, movement, and undersized or failed timber before we lay a single board. Older decks in Mt Eden, Epsom and Remuera often hide surprises down there – we would rather find them before the new boards go down, not after.

    When to replace

    Six signs your deck needs replacing, not patching

    01

    Soft or spongy boards

    Boards that feel spongy, flex under your weight, or crumble at the edges have taken on water and started to rot. Once rot is through the boards it is usually into the joists below as well, and a few replacement boards will not fix a frame that is going.

    02

    Bounce or sway

    A deck that bounces underfoot, sways when you lean on the rail, or feels loose where it meets the house has a problem in the framing or the fixings. On a raised deck that is a safety issue, not a feeling – it points to the structure below, which is exactly what we check before quoting.

    03

    Rusted or lifting fixings

    Nails that keep lifting, screws that spin, or rusted brackets and joist hangers are a sign the timber around them has softened or the fixings have failed. Re-nailing a board back down is a short-term patch when the timber holding it is no longer sound.

    04

    Sinking or rotten piles

    If one corner of the deck has dropped, or the posts are rotten, split or loose in the ground, the deck is only as good as what is holding it up. Posts and piles at ground level are where rot hides, and they are the first thing we check when a deck is moving.

    05

    Splitting or greyed timber

    Boards that have split, cupped, or gone silver-grey and rough are past what oil and a water blast will bring back. When most of the deck surface has weathered out, replacing the boards costs less over time than sanding and coating timber that is already failing.

    06

    A loose or low balustrade

    A handrail that moves, gaps a child could slip through, or a balustrade lower than the current height rule are safety issues on any raised deck. We flag where the balustrade needs to meet the Building Code and sort it as part of the replacement.

    Important – decks, consent and building work. A deck more than 1 metre above the ground is Restricted Building Work under the Building Act, which means it has to be built or supervised by a Licensed Building Practitioner and usually needs building consent from Auckland Council before work starts. Lower decks close to the ground can often be built without consent, but it depends on height, size and how the deck attaches to the house. We assess where your deck sits, handle the LBP side, and point you to the right consent path rather than guessing. Confirm your situation with Auckland Council or an LBP – rules at building.govt.nz.

    Why Auckland homeowners & landlords use us

    What decides whether a new deck lasts is what it is built on

    We check the substructure below – the piles, posts, bearers and joists – before we quote, because laying beautiful new boards over a rotten or undersized frame just buys you the same problem in a few years. A dropped corner or a bit of bounce often traces back to rotten posts or piles you cannot see from above.

    From villas in Grey Lynn and Ponsonby through to rentals in Henderson and Papatoetoe, same process every time: look underneath first, quote the whole job, build it once – so you are not paying twice.

    For landlords & property managers

    Deck replacement for landlords – safe, sound, and sorted around your tenants

    A rotten deck or a loose balustrade on a rental is a hazard, not just a look problem – under the Residential Tenancies Act, keeping the property in a reasonable state includes safe outdoor structures, and a soft board or a wobbly handrail is exactly what a tenant or an inspection will flag. We prioritise tenanted callouts, coordinate access with your tenants, and can batch deck work across your portfolio: assess them together, flag the ones that need doing now, and schedule around your tenancy turnovers. One scope, one point of contact, lower per-property cost.

    FAQs

    Deck replacement FAQs – Auckland

    How much does deck replacement cost in Auckland?

    Deck replacement is usually priced per square metre. As an indicative guide, fully installed, treated pine runs roughly $350 to $550 per square metre, kwila and other hardwoods around $550 to $900, and composite boards like Ekodeck about $550 to $850. A small deck of 10 to 20 square metres typically lands around $5,000 to $15,000, a medium deck of 20 to 40 square metres around $15,000 to $35,000, and a large or elevated deck $30,000 and up. Consent, where it is needed, usually adds about $2,000 to $5,000, and difficult access or earthworks add more. We check the substructure before quoting, then give you one fixed price covering removal, the frame, supply, build and rubbish removal.

    Do you check the substructure before rebuilding the deck?

    Yes, every time, before we quote. Building a new deck on rotten posts, sinking piles or undersized bearers just hides the problem until it comes back, usually within a few years. We check the piles, posts, bearers and joists for rot, movement and failed timber, and if the frame needs repair or replacement we tell you up front and price it into the fixed quote. It is the step cheaper operators skip, and it is the main reason decks fail again soon after being replaced.

    Do I need building consent to replace a deck?

    It depends on the deck. Under the Building Act, a deck more than 1 metre above the ground is Restricted Building Work and generally needs building consent from Auckland Council, built or supervised by a Licensed Building Practitioner. Lower decks close to the ground may not need consent. Because the rules turn on height, size and how the deck attaches to the house, we do not make the call off a photo. We assess your deck, tell you where it sits, and bring in an LBP and the consent process where they are required. You can confirm your situation with Auckland Council or at building.govt.nz.

    How long does it take to replace a deck?

    It depends on the size, the height, the decking material, and whether the substructure needs repair or the job needs consent. A straightforward ground-level deck replacement is quicker than an elevated deck that needs new piling and a consent. We give you the expected timeframe in your fixed quote before any work starts, so you know what to plan around. We do not promise a day count sight unseen, because the frame and consent status drive it.

    Pine, kwila, or composite – which decking is best?

    It comes down to budget and how much upkeep you want. Treated pine is the most affordable and takes stain well, but needs oiling every year or two. Kwila and vitex are hardwoods with a rich look that handle traffic well when maintained. Composite boards like Ekodeck cost more up front but do not need oiling, will not splinter, and hold their colour, which suits busy households and rentals. We walk you through the trade-offs and match the decking to how you will actually use the space.

    Can you replace a rotten or unsafe deck?

    Yes, worn-out and unsafe decks are a large part of what we do. If a deck is bouncing, the posts are rotten, or the balustrade is loose or too low, the safe fix is usually to replace it rather than patch around failing timber. We strip out the old deck, check what is underneath, repair or rebuild the substructure where needed, and build a new deck with a balustrade that meets the Building Code. If a raised deck feels unstable, keep people off it until it has been checked.

    Can you replace decks across multiple rental properties?

    Yes. We batch deck assessments and replacements across landlord portfolios regularly. If you have several rentals with tired, rotten or unsafe decks, we can assess them together, flag the ones that need doing now, schedule the work around your tenancy turnovers, and give you a single scope covering everything. One call, one company, one point of contact, and a lower per-property cost than booking them one at a time.

    Do you build the balustrade and steps too?

    Yes. A deck replacement includes the balustrade, handrail and steps built to suit the deck, not just the boards. On a raised deck the balustrade has to meet the current height and spacing rules in the Building Code, and we flag where an existing rail falls short and build the new one to comply. Steps are scoped and priced as part of the same fixed quote.

    Will you remove and take away the old deck?

    For most jobs, yes. We remove the old decking and any rotten framing, dispose of it, and leave the site clean and ready. We confirm exactly what is included in your fixed quote so there is no question about who is removing what. The old timber and offcuts are taken away as part of the job, so you are not left with a pile of rubbish to deal with.
