Commercial Drain Cleaning & Hydro Jetting

Blocked drains in a commercial or industrial building are not a maintenance issue. They are a liability. Grease buildup, root intrusion, and scale accumulation shut down kitchens, flood loading docks, and trigger health code violations — and they get worse every day they go unaddressed. Greg’s Plumbing provides commercial drain cleaning and high-pressure hydro jetting to restaurants, property managers, industrial facilities, and commercial buildings throughout Hamilton, Stoney Creek, Ancaster, Dundas, Grimsby, and the surrounding area.

What Commercial Hydro Jetting Is and Why It Beats Snaking

A drain snake punches through a clog, but commercial hydro jetting removes the buildup that caused it in the first place.

Snaking Opens the Line, But It Does Not Clean It

Snaking has its place for a simple residential blockage. In a commercial or industrial building, it is rarely enough.

Grease coating a restaurant drain line, soap scum and waste packed into an apartment stack, mineral scale in an industrial floor drain, or sludge sitting inside a sewer line will not be fully removed by a snake. A snake usually bores a small hole through the buildup, so the line flows again for a short time.

That is why the same drain often backs up again a few weeks or months later. The clog was pierced, but the pipe was never properly cleaned.

Hydro Jetting Cleans the Full Pipe Wall

Hydro jetting solves the actual problem. We feed a specialized nozzle into the line and run high pressure water through it, reaching up to 4,000 PSI depending on the pipe, blockage, and job conditions.
The water scours the inside wall of the pipe from every angle. It cuts through grease and fat, flushes out root tendrils, breaks up scale, and carries debris downstream and out of the system.
Instead of leaving the pipe barely open, hydro jetting helps restore the full diameter of the line so water, waste, and grease can move the way they should.

Built for Commercial and Industrial Drain Lines

Our hydro jetting equipment is truck mounted and rated for commercial and industrial line sizes, including large diameter sewer mains, grease lines, and parking lot catch basins.

This is not the small machine used for a typical residential drain call. Hamilton businesses searching for hydro jetting, hydro flushing, or hydrojet plumbing are usually dealing with heavier buildup, larger pipes, and higher risk if the line fails. That is the level of equipment we bring to commercial drain and sewer jobs.

Commercial Drain Problems We Clear in Hamilton

From grease and roots to recurring sewer backups, hydro jetting handles the commercial drain issues that snaking, chemicals, and waiting do not.

Root Intrusion

Tree roots chase moisture into joints and cracks in older lines, then expand and catch debris until the drain backs up. We cut and flush the roots with hydro jetting, then run a camera so you can see the joint and decide on repair or lining with real information.

Grease and FOG Buildup

Restaurants, cafeterias, and food service operations accumulate fats, oils, and grease inside drain lines no matter how well the grease trap is maintained. The buildup narrows the pipe and eventually seals it. Hydro jetting strips the grease layer off the pipe wall and restores full flow.

Sludge, Scale, and Sediment

Industrial facilities, warehouses, and older commercial buildings build up sediment and mineral scale inside floor drains and mains over years. Standard drain cleaning leaves it behind. High pressure jetting removes it and extends the working life of the line without digging.

Recurring Sewer Backups

A drain that backs up every few months has an accumulation problem, not a single clog. Jetting clears the line completely, and the camera inspection that follows tells us whether a structural issue downstream is catching debris and causing the repeat backup.

Catch Basins and Parking Lot Drains

Catch basins in commercial lots and loading areas fill with sediment, oil, and road debris until they back up into your property and create a liability. We clean and flush them on a schedule or as an emergency call.

Commercial Sewer Mains

We service mains up to large commercial diameters. Whether you manage a multi unit residential building, a plaza, or an industrial site with several stacks feeding a shared main, we have the equipment and line sizes to clear it in one visit.

How Our Commercial Drain Cleaning Service Works

Every commercial hydro jetting job follows the same four steps, so you get a clean line and proof that it is clean.

Step 1

Assessment and camera inspection

We start by inspecting the line with a drain camera to locate the blockage, identify what is causing it, and confirm the pipe can be safely jetted. You get a clear picture of the problem before any work begins.

Step 2

Hydro jetting at the right pressure

We select the correct nozzle and pressure for your line size and material, then jet the full run. Grease, roots, scale, and sludge come off the pipe wall and flush out of the system completely.

Step 3

Verification with the camera

We run the camera through the line a second time and show you the result. You see a clean pipe at full diameter, which is your proof the job is done rather than just temporarily moving.

Step 4

Report and recommendations

If the camera reveals a structural issue such as a cracked joint, a bellied section, or a damaged main, we document it with footage and walk you through the options. For property managers and building owners we can provide that footage for your records, compliance files, or insurance purposes.

Commercial and Industrial Properties We Serve Across Hamilton

Our commercial drain cleaning and hydro jetting service is built for the kinds of properties that cannot afford a drain shutting down.

Restaurants and Food Service

Kitchens in Hamilton, Stoney Creek, and Ancaster generate constant grease load. We keep your drain lines and grease line flowing so a backup does not close your kitchen during service or trigger a health inspection issue.

Property Managers and Condo Boards

Multi unit buildings share stacks and mains, so one blockage can affect many tenants. We provide scheduled jetting, emergency response, and written documentation for boards and owners.

Industrial and Manufacturing Facilities

Floor drains, trench drains, and process lines collect sediment, scale, and waste. Our equipment is sized for industrial buildup and larger commercial lines.

Retail, Plazas, and Office Buildings

A backed up drain or catch basin is a customer facing issue and a liability. We clear it quickly and can set up maintenance to prevent repeat problems.

Institutional and
Multi-Tenant Buildings

Schools, care facilities, and large buildings need drainage systems that stay reliable. We provide planned hydro jetting and fast emergency service when needed.

Scheduled Maintenance Accounts

Regular jetting helps prevent surprise backups and turns emergency drain calls into predictable maintenance. Ask about a commercial drain maintenance agreement.

Hydro Jetting vs Traditional Drain Snaking

Both clear a drain, but only one removes the buildup that causes commercial backups to return.

For a one time residential clog, snaking is fine. For a Hamilton restaurant, plaza, industrial site, or multi unit building, hydro jetting is the service that actually keeps the line clear and stops the repeat call.

Emergency Commercial Drain and Sewer Service in Hamilton

When a drain or sewer backs up in a commercial building, every hour counts. A flooded restaurant kitchen stops service. A sewer backup in a multi unit building affects every tenant on the stack. A blocked floor drain on an industrial site can shut down a process line. These are not problems you can leave until tomorrow.

Greg’s Plumbing and Heating provides emergency commercial drain and sewer service across Hamilton, Stoney Creek, Ancaster, Dundas, and the surrounding area. We arrive with truck mounted hydro jetting and camera equipment ready to clear the blockage on the first visit, not just diagnose it and book a return trip.

We also know the local system. We work with City of Hamilton sewer backups regularly and can tell quickly whether the problem sits on your side of the property line or in the municipal main, which determines who is responsible and what happens next. That knowledge saves you time and money when you are dealing with an emergency.

FAQ – Commercial Drain Cleaning and Hydro Jetting

Cost depends on the line size, the length of the run, how severe the blockage is, and whether the job is scheduled maintenance or an emergency. Because every commercial property is different, we provide a quote after understanding your situation rather than a flat number. Scheduled maintenance accounts typically cost less per visit than emergency calls.

It depends on the property. A busy restaurant kitchen may need jetting every three to six months because of grease load, while a low volume office building may only need it once a year. We help you set a maintenance cycle based on your actual usage so you are not paying for service you do not need or waiting until a backup forces the issue.

In most cases yes, which is why we run a camera inspection first. The camera confirms the pipe is sound enough to jet safely and lets us adjust the pressure to the line. If we find a pipe that is too damaged to jet, we tell you before we start and recommend the right repair instead.

A snake bores a hole through a clog and the buildup returns quickly. Hydro jetting uses high pressure water to clean the full inside of the pipe, removing grease, roots, and scale so the line stays clear far longer. For commercial drains, jetting is the lasting solution.
