Planned upkeep for business sites across Northern Sydney. Reduce emergency callouts, extend asset life, and maintain compliance with a single licensed contractor.
Put simply, we check and fix your pipes and roof on a set plan. This stops small issues from growing into big, costly ones. You get less stress and fewer surprise bills. We handle all the parts you do not want to think about. Our team does the hard work so you can focus on your core job.
Commercial maintenance is the scheduled check, servicing and repair of plumbing and roofing assets in commercial, industrial and public buildings. Unlike reactive (emergency) work, maintenance is planned — typically quarterly, monthly or annually depending on the asset type and legal needs.
Our commercial upkeep plans cover hot water systems, backflow prevention devices, grease traps, roof drainage and guttering, TMV (thermostatic mixing valve) testing, fire hydrant booster compliance, sewer and stormwater systems. General plumbing fixtures across multi-tenancy buildings, retail centres, schools, aged care sites, hotels, and strata properties.
Fixing things before they break costs far less than an urgent call-out. A small spend now saves a large bill later. Most of our clients cut their repair costs by more than half. Think of it like a car service. You pay a bit now to avoid a big tow bill later.
Emergency plumbing callouts cost 2–4× more than planned service visits. A blocked grease trap. Overflows on a Saturday night, a failed TMV in an aged care site, or a roof leak that damages ceiling tiles and electrical systems — all of these are preventable with a structured upkeep plan.
Beyond direct repair costs, unplanned failures cause business disruption, tenant complaints, insurance claims, and compliance breaches. A $300 quarterly check prevents a $5,000+ emergency repair and the associated downtime.
| Scenario | Reactive Cost | Preventative Cost | Saving |
|---|---|---|---|
| Grease trap overflow (weekend) | $2,800–$4,500 | $350/quarter pump-out | 75–90% |
| TMV failure in aged care | $1,200+ (emergency + compliance report) | $180/unit annual test | 80%+ |
| Roof leak causing ceiling damage | $3,000–$8,000 (repair + restoration) | $450/year gutter clean + inspection | 85%+ |
| Backflow device non-compliance fine | $2,200 (fine) + $600 (emergency test) | $280/year scheduled test | 90% |
We tag each pipe, valve and roof part with a barcode. After each visit, you get a clear report with photos. This makes it easy to track what was done and when. No more lost paper trails or guessing what was last checked. You can pull up any asset and see its full history in seconds.
Every asset under our upkeep plan is barcoded and tracked in our field management system (Simpro). Each visit generates a digital report with photos, condition ratings, and recommended actions — delivered to the property manager or site team within 24 hours of the visit.
This gives you a complete audit trail for compliance, insurance, and capital planning. You know exactly what condition each asset is in, when it was last serviced, and what work is coming up — without relying on memory or paper records.
Some gear must be tested by law each year. We keep track of all due dates for you. This keeps you on the right side of the rules and avoids fines. You do not need to know the codes. We know them and we make sure you pass.
Many commercial plumbing assets have mandatory testing intervals set by NSW legislation, Australian Standards, or local council needs:
Non-compliance carries fines, insurance implications, and — in aged care and healthcare — potential loss of licence. Our upkeep plans are structured around these legal intervals so you never miss a deadline.
We work with many types of sites. From aged care homes to schools, pubs to shops. Each site has its own needs, and we know them well. We have done this for years across all sorts of buildings. No job is too big or too small for our team.
Our commercial maintenance clients in Northern Sydney include:
You pick a plan that suits your site. We show up on time, do the work, and send you a report. No surprises, no hidden fees. It is that simple. You lock in a price and we stick to it. This gives you peace of mind all year round.
We tailor each upkeep plan to the property's specific assets, legal needs, and budget. The typical process:
Contracts are flexible — we work with property managers, site teams, body corporates, and owner-operators. No lock-in contracts; we retain clients through service quality, not contractual obligation.
Here is how a typical job works from start to end. We aim to make the process clear and stress-free for you. Each step is laid out so you know what to expect. We keep you in the loop at all times. No jargon, just plain facts about what we are doing and why.
Our approach to commercial maintenance in Northern Sydney combines planned preventative work with rapid, technically precise reactive maintenance. We balance compliance, safety and asset longevity so your site maintenance delivers predictable performance and measurable risk reduction. Below is the step‑by‑step process we follow on every commercial job — from small retail tenancies to large aged care sites and industrial plants.
We start by confirming scope, access needs and any immediate safety issues. For planned upkeep deals we collect an existing asset register where available; for reactive calls we establish the problem and schedule appropriate crews. For Northern Sydney sites we also check for site-specific constraints such as steep sandstone blocks, heritage restrictions or heavily treed surrounds that affect access and methodology.
Before work begins our crew conducts a site risk assessment and implements control measures. O’Brien utilises 17 site‑specific SWMS templates that cover common commercial maintenance activities (roof work, confined space drainage, hot water plant servicing, high‑pressure jetting, etc.). These SWMS are used to brief crews and subcontractors and are continually updated to reflect lessons learned and legal changes.
We use non‑invasive diagnostics first where possible. CCTV drain cameras to inspect sewer lines, thermal imaging for hidden roof leaks, and digital check tools for roof membranes and flashings. Results are captured in our digital check reporting platform and linked to asset barcodes so every check is recorded against the correct asset for future planned maintenance.
After diagnostics we prioritise actions by safety, compliance and service continuity. For reactive maintenance this means immediate containment and temporary repairs where needed, followed by a scoped repair plan. For planned maintenance we use the asset register and check history to set service frequencies and a maintenance calendar. Aligns with your day-to-day needs and legal obligations (for example annual backflow testing or TMV compliance testing).
We select crews and gear based on the task: commercial‑grade hydro‑jetting for grease‑choked storm drains, crane or elevated work platform access on steep roofs, rope access for confined roof edges on sandstone blocks. Appropriate fall‑protection for heritage buildings. All teams carry calibrated backflow test kits, TMV testing gear and the tooling required for commercial hot water plant servicing.
All work is completed to Australian Standards and manufacturer specifications. Where applicable we perform statutory tests — backflow device test certificates, TMV set‑point proof and handover records for hot water plant commissioning. We ensure stormwater outlets and gutters meet local council needs for discharge and have documented remediations where necessary.
Upon completion we upload check photos, test certificates and service notes to your asset register using barcode scanning. This provides instant traceability for compliance audits and simplifies future planned maintenance scheduling. For strata and site managers we can integrate reports into property care platforms on request.
Reactive repairs that require ongoing monitoring are scheduled into the planned maintenance calendar. Planned upkeep deals are adjustable based on seasonal risk (e.g. increased gutter clearing and roof checks before winter storms for heavily treed Northern Sydney properties).
Not sure if your site needs help? Here are some red flags to watch for. Catching these early saves time and money. Do not wait for a flood or a fine. A quick check now can stop a big problem later.
Business sites in Northern Sydney exhibit particular warning signs due to mature trees, older systems and steep terrain. Early detection limits downtime and prevents compliance breaches. Watch for these indicators:
Here is a rough guide to what things cost. Prices vary by site size and job scope. We always quote up front so you know the cost before we start. No hidden fees or surprise bills. What we quote is what you pay.
We offer transparent pricing for reactive commercial maintenance and bespoke quotes for planned upkeep deals. Below is the structure and examples using our published reactive rates.
These rates apply to reactive commercial work across Northern Sydney suburbs from our Hornsby base. The first hour covers mobilisation, onsite diagnostics and initial containment/temporary repairs where required.
Typical reactive scenarios (illustrative):
Note: parts, materials and specialist gear hire (e.g. elevated platform, crane, or major replacement components) are additional and quoted separately. Emergency after‑hours or weekend work may incur different scheduling; contact our 24/7 line on (02) 9477 1519 for immediate response.
Planned upkeep deals are quoted based on the asset register, agreed service frequencies and site risk profile. Factors that influence contract pricing include:
We provide a transparent schedule of services and deliverables with each planned maintenance quote so site managers can budget and comply with audit needs.
Due to the region’s mature root systems, steep terrain and heritage buildings, planned maintenance is often the most cost‑effective option for commercial clients. Routine CCTV checks and scheduled roof/gutter cleaning reduce the likelihood of large emergency repairs on sandstone blocks and prevent costly leakage into heritage interiors or aged care sites where water damage has higher consequences.
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.
While our work covers both plumbing and roofing, commercial maintenance differs significantly from home service in scope, legal needs and records management. Below we outline the key differences so building owners and site managers understand expectations.
Commercial sites. Offices, retail centres, hotel venues, aged care homes, schools and industrial sites — typically have larger, more complex systems: multiple sanitary fixtures, commercial hot water plants, grease interceptors, fire services plumbing, and larger roof areas with membranes or complex penetrations. Home jobs are smaller scale and usually have simpler legal needs.
Commercial sites face stricter compliance obligations: annual backflow testing, TMV testing for outlets. Service aged care or healthcare sites, grease trap maintenance aligned to council trade waste policies, and fire hydrant/hose reel plumbing testing. These require certified test gear, calibrated meters and certified reporting. Homes generally do not have the same frequency or records needs.
Site maintenance demands an auditable record. O’Brien provides barcode‑linked asset registers, digital check reports and statutory test certificates that can be shared with regulators, insurers and facility managers. Home work usually involves a single invoice and a simple service report.
Northern Sydney business sites often sit on steep slabs or heavily treed blocks. Roof access on sandstone escarpments or high‑rise strata requires specialised access methods, harness systems, elevated work platforms or even rope access. Our 17 SWMS cover these scenarios. Home access is usually simpler but can still require specialised safety engineering for older homes or multi‑storey dwellings.
Commercial clients typically require guaranteed windows, minimal disruption to operations and rapid response for business‑critical systems. Planned upkeep planmes are designed around trading hours and peak periods to minimise downtime. Reactive home work is often scheduled for convenience rather than to strict day-to-day constraints.
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.
Northern Sydney’s environment — mature gardens, heavy tree canopy, older housing stock and sandstone topography — creates specific maintenance challenges. The following prevention tips are tailored to reduce reactive maintenance and extend the life of your plumbing and roofing assets.
Root intrusion from mature trees is a leading cause of sewer failure in this region. Schedule CCTV checks every 12–24 months for properties with established trees or where older copper/galvanised pipes remain. Early identification lets you fix joints or install root barriers before a full collapse.
Grease trap performance deteriorates quickly in busy kitchens. Set service frequencies based on actual usage — monthly or fortnightly for high‑volume venues. Maintain records to satisfy council trade waste needs.
Backflow devices and TMVs are safety and compliance critical. Annual testing ensures potable water integrity and scald protection respectively. For aged care and schools, adhere to statutory timelines and keep certificates accessible for audits.
Clear gutters, downpipes and outlets before winter storms. Heavily treed Northern Sydney properties require two clearances a year — autumn and spring — to prevent leaf build‑up and stormwater ponding on membrane roofs.
If tree roots are close to sewer mains, consider root barriers, regular chemical root control by licensed contractors or strategic pruning in consultation with arborists. Avoid invasive excavation near sandstone slabs where drainage gradients are critical.
Heritage properties demand non‑destructive approaches: temporary patching with breathable membranes, careful removal and replacement of flashings. Consultation with heritage consultants when altering rooflines or gutters to maintain aesthetic and statutory compliance.
Commercial hot water plants should be serviced at manufacturer intervals. Monitor return temperatures and pressure relief valves for early signs of degradation. For high‑demand sites (hotel, aged care), maintain spares inventory and service contracts to reduce downtime.
Sloping sandstone blocks can shift and alter stormwater flow. Periodic checks of pits and grading ensure runoff is directed away from entrances and building foundations, avoiding erosion and internal infiltration.
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.
Efficient, safe and compliant commercial maintenance relies on the right tools and systems. O’Brien deploys industry‑grade technology that is particularly useful in the Northern Sydney context where diagnostics and minimal intervention are critical.
We tag major assets (boilers, backflow devices, TMVs, grease traps) with barcode IDs. Field technicians scan these during checks and services so each maintenance event is logged against the right asset. This improves traceability and simplifies rules reporting for facility managers.
Our digital reports include timestamped photos, test results and recommendations. These reports can be exported for council audits or integrated into property care platforms. For strata and large campus sites, digital reporting ensures consistency across multiple trades and vendors.
Hydro‑jetting removes grease, root matting and mineral scale from drains without the need for excavation. This is especially effective for hotel sites and older sewer mains in mature garden areas where tree root intrusion is common.
CCTV cameras allow precise diagnosis of sewer and stormwater issues. We use pan/tilt cameras and sonar where required for long‑run mains. Early CCTV check avoids unnecessary digging on sandstone blocks and identifies exact pipe condition for informed fix-up.
Calibrated, certified testing kits ensure accurate annual backflow test results and TMV set‑point proof. Certified test results are provided with every maintenance event to support compliance for aged care, schools and healthcare sites.
We carry specialised tools for storage and continuous flow plant. Pressure gauges, burner diagnostic gear, timer and control calibrators, and replacement components from major manufacturers to reduce downtime during servicing.
Thermal cameras detect hidden moisture paths and roof insulation issues. Drones provide safe, rapid assessments of large, steep or heritage roofs where access is difficult. These technologies reduce time on roof and limit disturbance to fragile substrates.
We use elevated work platforms, scaffolding, rope access systems and fall‑arrest gear as required by site conditions and our SWMS. For steep sandstone blocks and multi‑storey strata, the right access gear is essential for safe, non‑destructive maintenance.
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.

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.
We operate a 24/7 urgent response from our Hornsby base. Response time depends on the location and time of day, but our priority is to mobilise a suitably equipped crew as quickly as possible. For guaranteed response windows in high‑risk facilities (aged care, hospitals) we recommend a planned maintenance contract that includes emergency priority service levels.
The first hour covers mobilisation, arrival, an initial diagnostic assessment and any immediate containment work required to make the site safe. If repairs can be completed within the hour, we will proceed and provide an itemised invoice. Subsequent time is charged at $140/hr inc GST for reactive commercial work.
Planned maintenance is quoted based on your asset register and required service frequency. Contracts typically include scheduled checks, statutory tests (backflow, TMV), routine cleaning (grease traps, gutters), asset tagging and digital reporting. The quote will itemise visits, deliverables, test certificates and any exclusions so you can budget accurately.
Yes. For commercial clients we provide digital test certificates, service reports and photographic evidence linked to barcode asset IDs. These reports are suitable for council audits, insurance claims and in‑house compliance reviews.
Backflow devices are typically tested annually to maintain potable water safety. TMVs servicing vulnerable groups (aged care, childcare, healthcare) require regular testing and set‑point proof to meet scald‑prevention obligations. We can include testing frequencies in your planned maintenance contract according to statutory guidance and asset manufacturer recommendations.
We assess heritage constraints at the scoping stage and adopt conservative, reversible methods where required. On sandstone blocks with steep gradients, we use non‑invasive diagnostic tools (CCTV, drone and thermal imaging) and access methods that minimise substrate disturbance. We can work with heritage consultants when required.
Common causes include tree root ingress into older pipelines, grease accumulation in hospitality drains, and collapsed joints in ageing copper/galvanised systems. Regular CCTV checks and scheduled hydro‑jetting or root control reduce recurrence and prolong pipe life.
Yes. Our digital check reports and asset data can be exported or integrated with most facilities management platforms. We use barcode tagging so each service event updates the correct asset record for seamless reporting.
We provide a workmanship warranty on installations and repairs and will confirm the applicable warranty period in your quote. Component warranties provided by manufacturers are also passed through where applicable.
We implement a site‑specific SWMS and deploy appropriate access equipment (EWP, scaffolding, rope access), harnessing and fall‑arrest systems. For complex sites we coordinate lift plans and a rescue strategy prior to work. Our 17 SWMS cover the typical scenarios encountered across Northern Sydney business sites.
