TL;DR — Haven Compliance inspects, installs and certifies window safety in Mosman — one of Sydney’s most architecturally varied suburbs, where late Victorian terraces sit beside 1930s brick flats, postwar walk-ups and contemporary strata along Military Road and the streets running down to the harbour foreshores. Different eras produced different windows and different — often outdated — safety hardware, and Mosman’s famously engaged owners corporations expect documentation that survives an informed AGM. Every openable window is tested against section 118 — 125mm and 250 newtons — with the digital certificate and photographic report delivered the same day. Call +61 2 8000 0287.
Haven Compliance — a NSW window safety specialist familiar with the lower North Shore‘s most architecturally layered building stock. Along Military Road and the side streets stepping down to the foreshores, Mosman stacks late Victorian terraces against 1930s brick flats, postwar walk-ups and contemporary strata developments — and each era produced its own window types and its own, frequently obsolete, ideas about safety hardware.
We work with the strata managers and owners corporations responsible for that variety, and we calibrate to it: the compliance issues in a 1960s brick flat on Raglan Street are not the issues in a new development near Mosman village, and an inspection that treats them identically will miss what matters in both. One standard, era-aware execution, and documentation built for this suburb’s unusually well-informed committees.
Heritage character shapes which compliant device suits a window — never whether one is required. Everything rests on section 118 of the Strata Schemes Management Act 2015, which has bound every residential strata scheme in NSW since 13 March 2018. The owners corporation must ensure complying safety devices on each qualifying window — defined by three facts on the ground: the window opens, the internal floor is two metres or more above the external ground, and the opening starts below 1.7 metres from the floor.
What counts as complying is specific: the device limits the opening to 125mm or less, or is a robust screen, and in either case resists 250 newtons of force under the AS 5203:2016 test method. Adults may disengage a device for cleaning or airflow provided re-engagement is possible; ordinary flyscreens fail the force test and never satisfy the section. And the duty spans the whole building — lot windows included — not merely the common areas.
Two false beliefs — both previously in circulation around Mosman — merit correction. Annual inspection is recommended practice, not a statutory command: the Act names no interval, and we never pretend it does. The maximum fine for a non-compliant owners corporation is $550; the sobering exposure is a preventable fall and its civil and insurance sequels. Section 180 keeps the scheme’s records obligation at 7 years — the paperwork half of NSW’s strata window lock requirements.
The century of window-making on display. Victorian and Federation-era conversions carry timber double-hungs and casements whose frames demand fixings matched to the timber’s actual condition — and whose owners, reasonably, want hardware that does not disfigure the joinery. The 1930s flats add steel-framed windows with their own fixing challenges; the postwar walk-ups carry first-generation retrofit hardware now decades old; and the contemporary developments carry integrated systems that have mostly never been force-tested since handover.
Layer the foreshore factor over that — harbour-facing elevations age their hardware faster than the Military Road side — and the sloped streets running down to the water, where rear elevations can stand well above the external ground even when the entry reads as low-rise. Scoping and hardware selection both demand site-specific judgement here. None of this is an obstacle; it is simply why Mosman rewards a specialist. There is a compliant, sympathetic solution for every window era in this suburb — the craft is knowing which one belongs where.
Outdated hardware from earlier compliance eras — devices fitted decades ago to standards that predate the current force requirement, present and confidently non-compliant. Aged timber and steel fixings releasing under a fraction of 250 newtons. Harbour-side corrosion on foreshore elevations. Under-scoped rear elevations on the sloped streets. Never-verified integrated systems in the newer stock. And flyscreens presumed protective, as in every suburb we serve.
The legacy-hardware finding matters particularly here: a building that did the right thing in 2005 may be carrying devices that pass a glance and fail a newton meter — which is exactly the distinction an engaged committee should want tested.
With the documentation standard set by the audience. Mosman’s owners corporations attract owner-occupiers as much as investors, and its committees are among the most actively engaged on the lower North Shore — the kind where an owner at the AGM asks whether this year’s window safety inspection happened and requests the record. Our output is designed to be that record: a formal digital compliance certificate plus a photo-backed report specific enough that a committee member who was not present understands exactly what was found, window by window.
The visit itself runs on the standard discipline: access and entry notices through the manager’s process, every qualifying window measured against the actual external ground (those sloped streets), tested to 125mm and 250 newtons, and photographed. Heritage joinery is assessed for sympathetic hardware options; harbour elevations get the corrosion check; and authorised replacements are fitted on the spot with REMSAFE hardware.
Certificate and report arrive the same day — filed before the question can be asked, which is the position every strata manager prefers to answer from. For the complete on-site sequence, see our inspection process guide.
Heritage-sympathetic hardware selection is part of the job here, not a premium line item. Costing runs per unit and locks before booking: unit count, access and window numbers set it, hours never do. The approved quote and the final invoice are the same document. The tariff is public and short: single property $250 + GST; two to ten units $490 + GST; eleven or more, fixed quote on request. The same-day certificate is inside every figure.
Windows that fail are priced individually in REMSAFE hardware — and replaced before we leave, where the committee has authorised it in advance. To spend less, consolidate: fold remediation into the inspection project rather than engaging twice, and ride a grouped run with nearby buildings rather than booking alone. Coordination is the hidden line item, and consolidation deletes it. One number, whole outcome: the inspection and all its documentation — photographs, register, same-day certificate — plus the hardware call-out, invoiced once.
Mosman committees do well to price the destination, certified compliance, rather than the first leg of a journey that bills per stop.
By matching the device to the joinery rather than forcing the joinery to the device. Timber double-hungs take discreet sash-travel limiters; casements take stays selected and finished to sit quietly on period frames; and where a window’s configuration defeats conventional restrictors, robust screen solutions can be specified to preserve sightlines. Fixings are chosen for the timber or steel’s actual condition — the century-old frame is an engineering fact, not an inconvenience — and every installed device is force-tested in place, because sympathetic and compliant must be the same object.
Two boundaries worth stating plainly. Heritage character never exempts a qualifying window from section 118 — aesthetics shape the solution, not the obligation. And conservation-area constraints in parts of Mosman may affect external alterations, which is one more reason to choose hardware that works within the existing joinery rather than against it. Committees that engage on this early get windows that are both safe and still themselves — which is, after all, why anyone bought into these buildings.
Strata managers whose portfolios span Mosman, Cremorne, Neutral Bay and across to the Spit — grouped scheduling, a register for every building and a reminder for each anniversary. Owners corporations and committees, notably Mosman’s engaged, question-asking ones, including self-managed schemes in the smaller conversions. Property managers and landlords in the suburb’s quality rental layer. Vendors and buyers in one of Sydney’s highest-value apartment markets, where a current window safety certificate removes a due-diligence question before it costs anyone a settlement day.
Cremorne and Neutral Bay have their own location pages; portfolio scheduling runs the whole lower North Shore.
Because Mosman’s committees will read the report — actually read it — and generalist documentation does not survive that. ” Devices sighted, building compliant” satisfies nobody who knows what the force test is; our reports show each window, its device, its measured result and its photograph, in language an informed owner can interrogate and an insurer or buyer’s solicitor can rely on. The technicians behind those reports do window safety exclusively and know the suburb’s window eras on sight.
One accountable provider, end to end — inspection, sympathetic REMSAFE installation, re-verification, records — at fixed pricing with same-day delivery. And the honesty notes, which this suburb’s committees particularly appreciate: NSW has no official inspector certification scheme, and no statute mandates annual inspection. The requirement is a building that remains compliant continuously; everything else is method and evidence.
With a cycle that respects both the hardware and the audience. Buildings on our annual reinspection and maintenance program get every device retested — harbour elevations checked hardest, legacy hardware watched for drift, heritage fixings checked for movement — with in-visit maintenance, sympathetic replacements where needed, and the register rolled forward. Each cycle produces the one-page change summary that turns the AGM’s window safety item into thirty seconds with an attachment.
Automated reminders track each building’s anniversary, so the record an engaged owner might request is always current when they do. Annual is best practice rather than statute, as we note everywhere — but in a suburb where committees genuinely check, the unbroken yearly register is worth more than any single certificate: it is the difference between asserting diligence and being able to hand it over.
Largely, yes — discreet sash limiters, period-sympathetic stays and carefully specified screen solutions can meet the 125mm and 250 newton requirements while respecting the joinery. Heritage character shapes the solution; it never exempts the window.
Because earlier compliance eras used hardware that predates the current force requirement, and because timber fixings, steel frames and harbour air all move with time. Legacy devices pass a glance and fail a newton meter more often than committees expect — the test settles it.
A formal digital compliance certificate plus a photo-backed report — every window, its result, its photograph — and, on the annual cycle, an unbroken year-by-year register. Produced the same day as each inspection, filed before the question arrives.
Yes — foreshore elevations age hardware faster than street-facing ones. Our cycles test those elevations hardest and fit marine-suitable replacements where corrosion has begun.
No NSW statute fixes an interval — annual is prudent best practice. The legal duty is a continuously compliant building, and for engaged committees the unbroken annual register is the cleanest proof of it.
