Planned maintenance, urgent response, compliance testing and reporting for strata buildings, unit complexes and body corporate properties across Northern Sydney.
In short, we look after the shared pipes and roof in your block. This means less hassle for owners and fewer surprise costs for the body corp. We handle all the common areas so no one has to argue about whose job it is. One team, one plan, one bill.
Strata plumbing maintenance is the scheduled and reactive plumbing work required to keep multi-unit home buildings, townhouse complexes, and mixed-use strata properties compliant, functional and well-maintained. Unlike single-dwelling home work, strata maintenance involves common property assets (shared pipes, risers, hot water plant, roof drainage, fire services). Are the responsibility of the owners corporation — not individual lot owners.
In Northern Sydney. Particularly in high-density areas like Hornsby, Waitara, and Gordon — strata buildings range from small townhouse complexes (6–12 units) to large home towers (50+ units). Our upkeep plans scale to suit any building size and complexity.
We visit on a set schedule to check and fix things early. This keeps costs down and stops small leaks from turning into big repairs. You set the plan and we stick to it. No missed visits, no excuses. Just good, steady upkeep all year.
A structured upkeep plan prevents emergency callouts, extends asset life, and keeps the building compliant with NSW legislation and Australian Standards. For strata properties in Northern Sydney, we develop a 12-month maintenance calendar. Covers all common-property plumbing and roofing assets — scheduled around tenant convenience and building access needs.
Typical planned service visits include quarterly gutter and downpipe clearing (critical in Northern Sydney's heavily treed suburbs), annual backflow device testing, annual TMV testing (where applicable), 6-monthly hot water plant check, annual roof check. Grease trap pump-outs at council-mandated intervals. Each visit generates a digital report with photos, condition ratings, and recommended actions — delivered to the strata manager within 24 hours.
Some items in strata blocks must be tested by law each year. We handle all the tests and give you the paperwork you need to stay on the right side of the rules. You do not need to chase us for certs. We send them to you as soon as the test is done.
Strata buildings have mandatory compliance obligations that carry significant penalties for non-compliance:
| Compliance Requirement | Standard | Testing Interval | Applies To |
|---|---|---|---|
| Backflow prevention devices | AS 3500.1 / Sydney Water | Annual | All properties with backflow devices on the water meter |
| Thermostatic mixing valves (TMVs) | AS 4032.3 | Annual | Buildings with vulnerable occupants (aged care, childcare, healthcare) |
| Legionella risk management | AS/NZS 3666 | Monthly–Quarterly | Buildings with warm water systems, cooling towers, or spa pools |
| Grease trap maintenance | Council trade waste agreement | Quarterly (typical) | Buildings with commercial kitchens or food preparation areas |
| Fire hydrant booster testing | AS 1851 | 6-monthly | Buildings with fire hydrant booster systems |
We manage the full compliance cycle: scheduling, testing, reporting, and certificate issuance. Test results and certificates are delivered to the strata manager in a format suitable for inclusion in the annual compliance register.
When a pipe bursts or a roof leaks at 2am, we answer the phone. Fast response means less damage and lower repair bills for the body corp. We know that strata issues affect many people at once. That is why we treat them as top priority.
When a common-property plumbing failure occurs. A burst riser, blocked sewer main, roof leak affecting multiple units, or hot water plant failure — the response must be fast, coordinated, and communicated clearly to the strata manager, building manager, and affected residents.
We provide priority urgent response for strata clients on upkeep deals. This means faster dispatch from our Hornsby depot, direct communication with the strata manager, and post-incident reporting that documents the cause, the repair, and any recommended preventative action. For after-hours emergencies, our plumbers are dispatched directly — no waiting for strata committee approval when water is flowing.
After each visit, we send a clear report to the strata manager. No jargon, just plain facts about what we found and what we did. You can share it with owners at the next meeting. It makes your life easier and keeps everyone in the loop.
Strata managers need clear, professional records for every service visit and repair. We provide digital reports within 24 hours of each visit, including photos of work completed, state checks of inspected assets, compliance certificates where applicable. Recommendations for future work (with indicative costs for budgeting).
Reports are formatted for direct inclusion in strata committee meeting packs and annual maintenance budgets. We also provide annual asset condition summaries that help the owners corporation plan capital works and set appropriate maintenance levies.
Here is a guide to typical costs for strata work. We quote up front so the body corp knows the spend before we start. No hidden fees or surprise bills at the end. What we quote is what you pay. Simple as that.

Strata managers like working with us because we keep things simple. One call, one team, clear reports, and no drama. We show up on time and do what we say. That is rare in this trade, and it is why they keep coming back.
Managing plumbing maintenance across a portfolio of strata buildings requires a contractor who is responsive, well-documented. Capable of handling both planned maintenance and emergency work without constant oversight. Strata managers in Northern Sydney choose O'Brien because:
Here is how a strata job works from start to finish. We aim to keep it smooth and clear for all parties. Each step is laid out so you know what to expect. We keep the strata manager in the loop at all times.
Our strata maintenance process is designed for clarity, compliance and minimal disruption to residents and building operations. Northern Sydney's older building stock, steep terrain and heavily treed sites present unique challenges — our process accounts for those from the first contact to final handover.
On arrival our crew completes a site-specific risk assessment and SWMS briefing. O'Brien holds 17 SWMS covering tasks commonly required on strata sites — from confined-space access to working at height on multi-storey roofs. Where heritage fabric or asbestos risks exist we apply additional controls and communicate any access or permit needs to the manager.
For blockages, ambiguous leaks or suspected root intrusion we deploy commercial CCTV gear to inspect pipe interiors and determine the precise cause and location. Where access is limited. Common on steep sandstone blocks or roofs with restricted fall zones in Northern Sydney — we adapt camera entry points and ensure minimal disturbance to grounds and garden beds.
Our crews are dual-qualified in plumbing and roofing operations where required — a major advantage when a single defect crosses disciplines (e.g. failing roof membrane causing internal plumbing leaks). Technicians carry out repairs, renewals or maintenance using the appropriate tools for common area plumbing and roof works, including TMV/backflow test kits for compliance testing.
Clients receive a detailed digital report with photos, video exports from CCTV checks where applicable, asset register updates, warranty details and next recommended service dates. For planned upkeep deals we also provide an annual compliance schedule and budget forecast so committees and managers can allocate funds with confidence.
Our 24/7 urgent response integrates with the planned upkeep plan: priority calls from strata clients on a maintenance contract are triaged and attended with priority response. After emergency works we follow up with a fix-up plan and options for permanent rectification under the strata scope.
Not sure if your block needs help? Here are some warning signs. Catching these early saves the body corp money. Do not wait for a flood in the car park. A quick check now can stop a big claim later.
Recognising early warning signs helps prevent costly repairs and avoids disputes between lot owners and the body corporate. In Northern Sydney, look out for these common indicators:

We provide transparent, practical pricing so committees and property managers can budget realistically. Below is a guide tailored to Northern Sydney strata work. All reactive attendance charges are as follows:
Notes on reactive pricing:
Planned upkeep deals are priced according to the size of the strata scheme, asset count and the level of service required. Typical inclusions are:
We prepare a tailored, written proposal and fixed annual fee for planned programs following a site audit. This proposal outlines scope, frequency, exclusions and any staged renewals required for ageing systems (for example, replacement of galvanised risers or roof membrane renewals).
Home jobs and business jobs are not the same. Business sites have more rules, bigger systems, and need set plans. Here is how they differ. The main gap is scale and red tape. We handle both, but the approach is quite different.
Strata maintenance spans both home and commercial assets. In Northern Sydney the differences are pronounced due to building use, legal needs and asset types.
A few simple steps can stop most problems before they start. These tips cost little but save a lot over time. You do not need to be a plumber to do them. Just a bit of care goes a long way. Here are the easy wins.
Proactive measures reduce emergency repairs and extend asset life. These tips reflect Northern Sydney’s specific risks: mature trees, older plumbing materials and challenging site topography.
We use the latest tools and gear to find and fix problems fast. This means less time on site and better results for you. Our gear lets us see inside pipes and find leaks without digging. It saves time, mess, and money.
Strata systems demand reliable diagnostics and durable safety gear. We combine proven technology with industry-standard tools to deliver accurate results and clear reports.
All check reports, test certificates and photographic evidence are compiled into digital reports. Reports are geo-tagged, time-stamped and linked to the asset barcode so property managers have an auditable record for compliance and budgeting.
We tag and barcode backflow devices, TMVs, pumps and other common-area plant. This creates a live asset register for planned maintenance and simplifies annual compliance cycles.
High-resolution drain cameras allow us to pinpoint root intrusion, fractured joints or sediment build-up in larger-diameter common drains. The resulting footage is exportable and becomes part of the digital file for the asset.
We bring field-calibrated test kits for thermostatic mixing valves and backflow prevention assemblies. Tests are completed on-site, and certificates issued electronically for your records.
Our crews carry the full range of commercial common-area plumbing tools for isolations, valve changeouts, riser repairs and temporary bypass installations to restore building services quickly.
For high-level work we deploy certified edge protection, harness anchor systems and temporary access platforms. These systems are mandatory on many commercial roofs and protect both our crew and the building’s insurance needs.
We have been doing this for years and know the local area well. Our team is licensed, insured, and shows up on time. Here is what sets us apart. We answer the phone, we show up when we say, and we do the job right the first time.
We combine local knowledge of Northern Sydney with systems that reduce risk, control cost and improve compliance outcomes for strata managers and committees.
Here are the most common things people ask us. We have kept the answers short and clear. If your question is not here, just give us a call. We are happy to chat and help you out.
Responsibility generally follows the strata plan and the by-laws. Common property (gutters, external downpipes, common area drainage, roof membranes over common areas, building risers and common hot water plants) is usually the body corporate’s responsibility. Fixtures within a lot are typically the lot-owner’s responsibility. Where responsibility is unclear. For example, a leak originating under the eaves of a lot but entering common corridors — our digital checks and CCTV footage help identify the source and support the committee’s decision-making. We always recommend reviewing by-laws and, when in doubt, seeking legal advice for dispute resolution.
Annual testing is standard for both TMV assemblies (for thermostatic mixing valve performance and scald prevention) and backflow prevention devices (to protect potable water). Some insurance policies and health departments may require more frequent testing depending on use. We keep records in the asset register and schedule the next test as part of a planned upkeep plan.
Root intrusion is common in Northern Sydney due to mature gardens. We inspect with CCTV to locate the intrusion and then recommend a fix-up plan — mechanical root cutting, repairs to fractured joints or lining/replacement of damaged sections. Recurrent issues may justify permanent solutions such as pipe lining or installation of root barriers in the verge (with council permission where applicable).
Yes. We understand the constraints and approvals often required on heritage-registered buildings. Our approach is conservative: we document existing fabric, work with heritage consultants where necessary, and use repair techniques designed to be sympathetic to original materials. We also complete SWMS relevant to heritage work and coordinate any permits or council approvals where required.
The setup typically begins with a site audit and asset proof (1–3 days depending on site size). We issue a tailored proposal within 7–14 business days of the audit, outlining frequency, deliverables and costs. After client acceptance we schedule the first round of checks and testing and provide a yearly calendar for compliance events.
Yes. Planned maintenance clients receive priority 24/7 emergency response. Our Hornsby-based teams are experienced in triaging call-outs for multi-storey and complex access sites, and we communicate expected arrival times and immediate risk mitigations to property managers.
We deploy certified roof edge protection, harness anchor points and temporary platforms as required. Work at height is conducted under the relevant SWMS and with gear inspected before use. We also coordinate exclusion zones on common areas and provide clear communication to residents when works affect access.
We provide independent, evidence-based reporting: CCTV footage, digital photographs, asset register records and time-stamped test certificates. Our reports identify the origin of faults and the scope of common property involvement — which helps committees make informed decisions and supports minutes and levy allocations. If a dispute escalates, our records can be submitted to adjudication bodies or legal counsel.
Yes. We coordinate with tenancy managers, schedule works to minimise day-to-day impact and provide the additional documentation often required for commercial audits (detailed test logs, maintenance histories and service level agreements). Grease traps, fire system interfaces and high-capacity stormwater systems are part of our commercial strata capability.
Prioritise safety: isolate electricity in affected areas if safe to do so, avoid standing water, and notify the body corporate/property manager. Call our emergency line or Hornsby office and provide details of location, visible damage and any imminent risks. We’ll arrange triage attendance, temporary mitigation (tarping roofs, temporary pumps) and a remediation plan with costs and timeline.
