If you manage strata long enough, you start to recognise the same repair themes popping up again and again: roof leaks after a storm, water showing up where it absolutely shouldn\u2019t, \u201curgent\u201d electrical defects, and a slow creep of wear-and-tear through corridors and common areas. The tricky part isn\u2019t identifying the issue; it\u2019s answering the question everyone asks next: \u201cRoughly what\u2019s this going to cost?\u201d<\/span><\/p>

This strata repair costs Australia guide is designed to give you practical, defensible <\/span>benchmarks<\/span><\/i> you can use for early budgeting, committee conversations, and to sanity-check quotes.\u00a0<\/span><\/p>

The cost ranges below are primarily drawn from the <\/span>Archicentre Australia Cost Guide 2026<\/span><\/a>, which states it\u2019s general advice, assumes typical conditions, and notes that its cost advice includes GST, helpful for strata discussions where people want \u201creal-world\u201d numbers.<\/span><\/p>

One important reality check: many of these benchmarks assume reasonable access and for roofing up to two storeys. In strata, access requirements (height systems, confined spaces, traffic management, resident disruption, after-hours shutdowns) can push costs higher than a simple baseline.<\/span><\/p>

Also, if you\u2019re in NSW, it\u2019s worth remembering that the NSW Government guidance is clear: the owners corporation is responsible for common property repairs (and it explicitly lists items like roof and gutters as owners corporation responsibility). That matters because getting the responsibility call right early can save a lot of back-and-forth when you\u2019re preparing a common property repair cost estimate Australia.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Roof issues tend to start small and annoying – a drip, a stain – and become expensive when they\u2019re ignored, like wet insulation, mould, ceiling collapses, electrical risk. The benchmark you\u2019ll often use is cost per square metre for repairing or replacing roof coverings.<\/span><\/p>

Archicentre\u2019s roofing benchmarks (noting \u201cup to two storeys: fixed to existing roof frame\u201d) include: concrete tiled roof $65\u2013$85\/m\u00b2, terracotta tiled $105\u2013$155\/m\u00b2, slate $390\u2013$650\/m\u00b2, fibreglass $48\u2013$70\/m\u00b2, polycarbonate $88\u2013$450\/m\u00b2, and steel roofing $60\u2013$130\/m\u00b2. Sarking is listed at $11\u2013$16\/m\u00b2.<\/span><\/p>

In strata, the difference between a \u201csimple repair\u201d and a \u201cproper fix\u201d is often access plus detailing around penetrations, gutters, and roof drainage. If the building is more than two storeys, treat these numbers as a floor, not a ceiling.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Gutters and downpipes - roof drainage failures\n\n\n\n\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t

A surprising number of \u201cmystery\u201d water ingress issues are actually drainage problems: blocked or undersized gutters, failed joints, incorrect falls, or downpipes that simply can\u2019t keep up in heavy rain. These are also classic common property items.<\/span><\/p>

Archicentre\u2019s benchmark for guttering and downpipes is shown per linear metre by material: PVC $43\u2013$72\/Lm, Zincalume $43\u2013$102\/Lm, Colorbond $49\u2013$109\/Lm, copper $138\u2013$187\/Lm, and stainless steel $120\u2013$215\/Lm.<\/p>

Where costs blow out in strata is rarely the gutter itself; it\u2019s safe access, edge protection, and the \u201cmake good\u201d work once you start uncovering rusted fascia or water-damaged eaves.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Electrical is one of those categories where you don\u2019t get to \u201cwait and see\u201d. Defects, compliance notices, nuisance tripping, and ageing infrastructure can force your hand.<\/span><\/p>

Archicentre\u2019s benchmarks list replaces switchboards at $900\u2013$3,000 and safety switches at $550\u2013$1,100.<\/span><\/p>

In strata, planning matters. If a board upgrade will require shutdowns, access to meter rooms, or coordination with essential services, that operational complexity can add cost even when the hardware is straightforward.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Common property lighting is a constant source of \u201csmall-but-urgent\u201d jobs: faulty fittings, upgrades for safety, or adding power and lighting in basements, plant rooms, foyers, and bin rooms.<\/span><\/p>

Archicentre\u2019s benchmarks include new light point $125\u2013$150 each (plus cost of fitting) and add power points $125\u2013$300 each.<\/span><\/p>

In practice, strata pricing here is heavily influenced by how difficult the cable run is (concrete, fire-rated penetrations, limited ceiling access) and whether the work needs traffic control or after-hours scheduling.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Drainage failures are often the \u201csilent budget killers\u201d because they don\u2019t always look dramatic, until a basement floods or a courtyard becomes a pond.<\/span><\/p>

Archicentre\u2019s drainage benchmarks include 90mm stormwater pipe (including trenching up to 900mm deep) $90\u2013$130\/Lm, stormwater pits and cover $560\u2013$1,500 per pit, trench grates $320\/Lm (plus varies by trench size and cover type), and agricultural pipe including trenching $45\u2013$65\/Lm.<\/span><\/p>

In strata, reinstatement is the big swing factor. If the area is paved, landscaped, waterproofed, or part of a podium structure, the \u201crepair\u201d is really a layered system rebuild, and that\u2019s where budgeting needs a bit of padding.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Once water has entered, you\u2019re not just fixing the leak; you\u2019re repairing finishes, restoring fire\/smoke integrity where relevant, and making the space look normal again.<\/span><\/p>

Archicentre lists plasterboard (including furring channels) at $81\u2013$98\/m\u00b2, and patching holes\/openings not exceeding 0.5m\u00b2 at $290\u2013$540\/m\u00b2.<\/span><\/p>

On paper those are clean numbers; on site, the cost depends on how much \u201cinvestigation\u201d is required (opening up ceilings, tracing moisture paths, drying time) and whether decorative features (cornices, roses, mouldings) need matching.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Repointing is one of those unglamorous jobs that pays off. Failed mortar lets water in, accelerates deterioration, and can cause internal damp issues that look unrelated.<\/span><\/p>

Archicentre\u2019s benchmark for repointing face brick walls is $13\u2013$22\/m\u00b2.<\/span><\/p>

In strata, the real variable is access. The repointing itself may be straightforward, but working at height, containing dust, and staging works around residents can materially change your final cost.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Damp is rarely a single-fix problem in strata, but there are common remedial items that show up repeatedly: injected damp-proof courses in older masonry and adding vents to improve underfloor or cavity ventilation.<\/span><\/p>

Archicentre benchmarks silicon injected damp-proof course at $55\u2013$85\/Lm, and new air vents at $55\u2013$80 each.<\/span><\/p>

These are useful \u201cfirst pass\u201d numbers for budgeting, but the key is diagnosis. If the moisture source is coming from failed drainage, bridging, or waterproofing issues, damp proofing alone may just delay the next complaint.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Painting is one of the most visible ways a building \u201cshows its age\u201d, and it\u2019s often where committees want strong value for money, because residents see it every day.<\/span><\/p>

Archicentre\u2019s benchmarks for painting (one undercoat, two finishing coats) include interior \u2013 plaster\/brick\/timber $20\u2013$40\/m\u00b2, and exterior timber, depending on condition: $25\u2013$60\/m\u00b2 (good condition) and $45\u2013$80\/m\u00b2 (poor condition). It also lists an anti-graffiti shield at $25\u2013$36\/m\u00b2.<\/span><\/p>

In strata, the preparation standard is the difference between a job that lasts and one that looks tired in 18 months. If your building has older paint layers (and potentially lead paint), make sure the scope spells out surface prep expectations. Archicentre itself flags \u201callow extra for\u201d items like lead paint removal.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Waterproofing failures in bathrooms, balconies, and podiums\n\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t

This is the one that keeps strata managers up at night, because waterproofing failures can trigger a chain reaction: leaks into lots below, damaged ceilings, mould concerns, disputes over responsibility, and extended disruption while drying and rectification happen.<\/span><\/p>

For a practical, on-the-ground signal, the<\/span> Queensland Building and Construction Commission <\/span><\/a>(QBCC) reports that each residential bathroom claim finalised under the Queensland Home Warranty Scheme during the 2024\u201325 financial year averaged almost $25,000 in rectification costs. That figure alone is a strong reference point when someone asks about waterproofing repair cost in strata apartment Australia.<\/span><\/p>

From a broader regulatory\/industry perspective, the Australian Building Codes Board (ABCB) impact analysis for waterproofing provisions notes that rectification costs for Class 2 buildings (apartments) are broadly in line across sources for balconies\/podiums\/external enclosures, costing around $24,000 per defect\/balcony. It also highlights that, for Class 3\u20139 buildings, internal wet area defect rectification can range between $50,000 and $225,000 per defect, and balcony\/podium defects can be around $40,000 per defect.<\/span><\/p>

If rectification ends up requiring a full strip-out and rebuild of a bathroom (which is common when membranes have failed and substrates are compromised), Archicentre\u2019s \u201cwet area fit out\u201d benchmark for a bathroom\/en-suite is $17,500\u2013$35,000.<\/span><\/p>

And finally, a responsibility note that matters in real strata life: the <\/span>NSW \u201cCommon property memorandum<\/span><\/a>\u201d includes original tiles and associated waterproofing affixed at the time of registration of the strata plan in owners corporation responsibilities, in the listed contexts. That doesn\u2019t replace plan\/by-law checks, but it\u2019s a credible anchor when you\u2019re navigating the \u201cwho pays?\u201d question.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

These benchmarks won\u2019t replace a proper scope and competitive quoting\u2014but they\u2019re enough to stop budget conversations from derailing into guesswork. Use them to build a calm, defensible common property repair cost estimate in Australia, then tighten the numbers with site-specific quotes.<\/span><\/p>

In NSW, the Government states the owners corporation is responsible for common property repairs, and schemes must obtain at least two independent quotes for work valued at $30,000 or more (with emergency exceptions). (<\/span>nsw.gov.au<\/span><\/a>) In Queensland, the Government similarly frames that the body corporate must maintain common property in good condition (and may be liable if failure causes damage to a lot). (<\/span>qld.gov.au<\/span><\/a>)<\/span><\/p>
