Maintenance plan vs. call-as-needed
Most commercial clients start call-as-needed. Here's when a maintenance plan makes sense.
| Call-as-needed | Preventive maintenance plan | |
|---|---|---|
| Response | Scheduled by availability | Priority scheduling for plan clients |
| Backflow testing | Booked separately each year | Tracked and booked automatically |
| Drain & stack care | Cleared after a backup | Scheduled jetting before problems |
| Reporting | Invoice per visit | Written condition reports per site |
| Best for | Small single-tenant sites | Multi-unit, restaurants, portfolios |

Upfront pricing
Commercial plumbing pricing in Ottawa
Commercial pricing depends on the building, the systems and the service level you need. A single retail unit needing a washroom repair is priced very differently from a 120-unit residential building on a maintenance plan.
For repairs we provide written estimates and work under your purchase-order process. For maintenance plans and backflow testing across multiple sites, we prepare a proposal with clear per-visit and per-device pricing so budgets are predictable.
After-hours rates are agreed in advance and documented in your onboarding so there are no surprises when a tenant calls at midnight.
- Written proposals and estimates
- PO and invoicing processes supported
- After-hours rates agreed in advance
- Multi-site and portfolio pricing
- Photos and reports with every visit

Facility guide
Commercial plumbing compliance and maintenance in Ottawa
For owners and property managers, good plumbing is about risk management. Here's what we help Ottawa commercial clients stay on top of.
Backflow prevention in Ottawa
Backflow happens when water flows the wrong way and contaminated water enters the drinking-water supply. The City of Ottawa's Water By-law requires many industrial, commercial, institutional and multi-residential properties to have appropriate backflow prevention devices.
These devices must typically be tested after installation and on a regular schedule by a qualified tester, with results submitted to the City. Check your notice from the City for your property's specific requirements — we can manage the testing and reporting for you.
Grease interceptors for food service
Restaurants, cafés and commercial kitchens generally must prevent fats, oils and grease from entering the City sewer. The City of Ottawa's Sewer Use By-law sets requirements for discharges, and grease interceptors are the standard way to meet them.
An undersized or neglected interceptor causes kitchen backups, odours and potential by-law issues. We assess sizing, repair and install interceptors, and help you set a cleaning schedule based on your actual volume.
Multi-unit buildings: preventing water damage
In apartment and condo buildings, one failed supply line can damage several units below. Scheduled checks of in-suite shut-offs, washing-machine hoses, water heater pans and toilet supply lines prevent many claims.
We also recommend clear riser shut-off maps, exercised isolation valves and leak-detection sensors in high-risk areas such as mechanical rooms. These are small investments compared with an insurance deductible.
Stack and main line maintenance
Kitchen stacks in residential buildings accumulate grease over the years, causing backups in lower-floor units. Scheduled hydro jetting of stacks and main lines keeps them flowing and reduces emergency calls.
A camera inspection before jetting confirms pipe condition, which is especially important for older cast-iron stacks in buildings constructed before the 1980s.
Commercial hot water systems
Commercial domestic hot water is often stored at higher temperatures to control bacteria such as Legionella, then mixed down at the point of use to prevent scalding. Mixing valves and recirculation pumps need regular checks to keep that balance safe.
We service large tank heaters, tankless arrays and indirect systems, and help you plan replacements before a failure takes hot water out for an entire building.
Tenant fit-outs and permits
Commercial fit-outs usually require plumbing permits and inspections under the Ontario Building Code. Coordinating plumbing rough-in early with the general contractor avoids delays when walls and ceilings are scheduled to close.
We provide shop-drawing input, rough-in, inspection coordination and finish plumbing, and we document everything for the landlord's records.
After-hours emergency planning
Every building should have a written plan for water emergencies: who tenants call, where the main and riser shut-offs are, who has access to the mechanical room, and which plumber is authorised to respond.
When we onboard a commercial client, we document these details so our 24/7 dispatch can act immediately — even at 3 a.m. on a holiday.
Choosing a commercial plumbing contractor
Look for licensed plumbers, adequate liability insurance, certified backflow testers, a real 24/7 response, and a company that can report clearly to owners and boards. Ask how they handle purchase orders, access and tenant communication.
The cheapest hourly rate rarely produces the lowest total cost. Fast diagnosis, fewer return visits and preventive maintenance are what protect your budget.
Restaurant plumbing emergencies
For a restaurant, a blocked kitchen drain during service or a failed hot-water heater before a health inspection can shut the doors. Hot water at adequate temperature is a requirement for dishwashing and handwashing under Ontario food premises rules.
We prioritise food-service emergencies, carry common commercial parts and can often install temporary hot-water solutions while a replacement heater is sourced.
Office and retail washrooms
High-traffic washrooms wear out flushometer diaphragms, sensor valves and fixture seals far faster than residential bathrooms. Out-of-order signs damage your customer experience and tenant satisfaction.
A planned service visit replaces wear parts before they fail, adjusts flush volumes and checks for hidden leaks. For accessible washrooms, we install fixtures that meet the Ontario Building Code's barrier-free requirements.
Booster pumps and water pressure in taller buildings
Mid-rise and high-rise buildings often need booster pumps to deliver adequate pressure to upper floors, and pressure-reducing stations to protect lower floors. When a pump fails or a control setting drifts, upper-floor tenants lose pressure first.
We troubleshoot booster systems, replace pressure-reducing valves and document settings so building operators have a reliable baseline.
Water damage response for property managers
When a unit leak is reported, speed matters. Our plumbers isolate the source, identify the responsible fixture or pipe, and document the cause with photos. That record helps the property manager, the condo board and insurers determine responsibility.
We also identify affected units below so restoration contractors can start drying promptly, reducing mould risk and total claim costs.
Light industrial and institutional work
Warehouses, workshops, clinics and schools have needs such as emergency eyewash and shower stations, trap primers, mixing valves, acid-neutralisation systems and specialised backflow protection.
We work with facility managers to maintain these systems, keep testing records and plan capital replacements, so plumbing never becomes the reason a site fails an inspection.
Our commercial reporting
Every commercial visit ends with a written report: what was found, what was done, photos of the work and recommendations ranked by urgency. Reports are emailed to the contacts you choose — site staff, property managers, owners or boards.
For maintenance-plan clients, we compile annual summaries that support budgeting and reserve fund planning, so you can replace aging equipment on your schedule rather than in an emergency.
Commercial drain and sewer services
Commercial kitchens, food courts and multi-unit buildings generate heavy drain loads. Grease, food solids and paper products build up in horizontal runs and stacks, causing slow drains and backups in the lowest units or floors.
We clear lines with cables and hydro jetting, camera inspect to identify problem sections, and schedule maintenance before backups disrupt tenants. Read more on our drain cleaning Ottawa page.
Plumbing during tenant turnover
Unit turnover is the ideal time to replace worn fixtures, supply lines and shut-off valves, check water heater age and confirm drains run freely. Catching these issues between tenants avoids emergency calls in the first month of a new lease.
We offer turnover inspections with a checklist and a written price for any recommended work, so property managers can approve items quickly.
Seasonal risks for Ottawa commercial buildings
Winter is the highest-risk season. Sprinkler and domestic lines in unheated vestibules, loading docks and parkades can freeze. Exterior hose bibs and irrigation lines need to be drained before the first hard frost.
Spring brings melt and storm surges that test sump pits and backwater valves. A pre-season check of pumps, alarms and valves in autumn and early spring protects your building and your tenants.
Response times and communication
When you call us, you'll speak to a person who records the site, access instructions and urgency. We confirm the arrival window and send updates if anything changes. On completion, you receive a report — not just an invoice.
For portfolio clients, a single point of contact keeps track of every site, so your team isn't repeating details on every call.
Insurance and liability
Commercial clients should confirm their plumber carries adequate commercial general liability insurance and WSIB coverage before work begins. We provide certificates of insurance on request and can name your property management company as an additional insured.
Clear documentation of every visit — cause, work done and photos — also simplifies any claim between owners, tenants and insurers.
Water conservation for commercial buildings
Water and sewer charges are a significant operating cost. Low-flow fixtures, sensor faucets, efficient urinals, leak detection on main supplies and repairing running toilets quickly all reduce consumption.
We can audit fixtures across a building, estimate savings and prioritise upgrades with the fastest payback.
