Hamilton response · Same day or next business day
When Hamilton businesses describe what they want from a Rex-Royal service provider, it usually comes down to four things: speed, expertise, transparency, no contract. That's our entire offer.
Hamilton market context
Hamilton's coffee machine fleet anchors three clusters: McMaster Innovation Park biotech and research office cafeterias, the Concession Street hospital corridor staff lounges running 24/7 for clinical teams, and the Ancaster Business Park and Stoney Creek industrial sites feeding shift operations. Hamilton's harder water profile (typically 150 to 180 ppm hardness) tightens descaling intervals and accelerates element wear on every super-automatic in the city.

Why Grajqevci
Call in the morning and a technician is usually on-site before the day is out. Most Rex-Royal jobs get diagnosed and fixed on the first visit.
Commercial coffee equipment is all we do, and Rex-Royal is one of the platforms we know best. Not a generalist guessing at a service manual. Genuine OEM parts, industry-standard procedures.
Flat rate for the visit, with parts billed separately. For bigger jobs you'll see a written quote on-site before we proceed.
Hamilton dispatch
Trusted by Toronto's most demanding teams
Our services
Boilers, grinders, brew units, milk systems, touchscreens, error codes. We troubleshoot the issue and quote parts before any work begins.
Plumbed-in or self-contained, we handle water filtration, calibration, and staff onboarding so your machine pours perfectly from day one.
Scheduled servicing tuned to your daily volume. Gaskets, seals, descaling, milk system overhaul. Extends machine life by years.
Rex-Royal faults we diagnose
Every issue below comes with a description of what causes it and what we do to resolve it. If yours isn't listed, call us anyway.
Scale insulating the heating element is the leading cause on untreated water, followed by element fatigue. We descale the circuit, test element resistance against spec, replace the element if output doesn't recover, and benchmark heat-up and hot-water throughput before reassembly.
A failed temperature sensor, a degraded element, or a relay sticking on the control board stops the boiler reaching setpoint inside the warm-up window. We test the sensor resistance against the reference table, check element resistance, inspect the relay, replace the faulty part, and clear the fault.
A weeping fitting, a worn brew-unit or hydraulic seal, or a blocked drain causing overflow. We pressure-test the circuits, dye-trace the chassis to the exact leak point, clear any drain blockage, and replace the failed seal or fitting rather than just retighten it.
A scaled level probe, a fill solenoid leaking past, a restricted supply, or an exhausted filter cartridge. We descale or replace the probe, test the solenoid, check upstream filtration, and confirm the fill cycle completes correctly.
The metal brewing unit stalls on packed grounds, a swollen seal, or a worn gearmotor after high-volume use. We strip the brew unit, clear the chamber, replace the seals and any worn cam or drive part, lubricate with food-safe grease, and verify clean cycling before the machine goes back on the counter.
A torn brew screen, a worn piston seal, or grind drifting too fine lets grounds through and flattens the shot. We inspect the brew unit, replace worn screens and seals, measure brew pressure, and recalibrate the grind and dose to bring extraction back to spec.
Burr wear is the usual cause, with calibration drift behind it. On the twin-grinder S300 and the up-to-three-grinder S500 one grinder often wears faster than the others. We weigh dose per grinder across a run of shots, measure the burr gap, recalibrate each side, and replace burrs that are past spec.
A small stone or other foreign object riding in with the beans, beans bridging above the throat, or a stuck hopper gate. We open the grinder, clear the obstruction, inspect the burrs for chips, replace them if damaged, and confirm the hopper feeds consistently.
On the touchscreen S300 and S500 this is usually a firmware hang rather than dead hardware. We run a controlled reset, check the firmware version, reflash from a known-good image if it sticks, and replace the display module only when the touch panel itself has failed.
We read the full fault log through the service interface, pin down whether the root cause is a sensor, valve, motor, or board, replace the specific failed component, and clear the log. Most error codes resolve in a single visit.
A grounds drawer not seated, a full-drawer sensor misreading, or a blocked drainage path will lock out brewing. We check the drawer sensor, clear the drainage, and replace the sensor if it reads unreliably so the machine stops false-stopping mid-service.
A level sensor in the cleaning circuit misreading, a blockage in the cleaning path, or the wrong cleaning tablet dosing. We diagnose where the cycle stalls, clear the circuit, verify the dosing, and watch a full cycle complete before we sign off.
We keep older Rex-Royal machines running after other shops have given up. For parts no longer in production we source from refurbisher networks, salvage from decommissioned units, and use validated aftermarket equivalents where the quality matches. When a repair stops making sense against the machine's value, we tell you straight.
Milk residue narrows the foam chamber and the air-intake line, so the foam thins or collapses. We strip and sanitise the milk circuit, replace worn O-rings and the air-intake parts, test the milk pump draw, and verify foam quality across the drink menu before leaving.
Usually a milk-temperature sensor out of spec or scale in the milk-side heat path. We test the sensor against a reference probe, descale the milk circuit, and replace the sensor if it reads out of spec. Most cases are a one-visit fix.
A clear sign the daily milk clean has been skipped or the cleaning agent is exhausted. We deep-clean and sanitise the whole milk pathway, replace stained milk lines, and walk the staff through the daily cycle so it doesn't come back.
Hamilton water profile
Hard to very hard, 140 to 180 mg/L CaCO3 typical from the Hamilton municipal supply (Lake Ontario sourced via the Woodward water treatment plant on Hamilton Harbour). Harder than Toronto and noticeably harder than Mississauga or Oakville. Locke Street and James Street North cafe operators we service in Hamilton typically run a softener cartridge plus 2 month descale intervals on busy bars.
Hamilton coverage
Real coverage, not a postcode list. Below are the three service zones we work most often, the kinds of operators we service in each, and the neighborhoods we cover regularly.
Heavy industry on the bayfront (ArcelorMittal Dofasco, Stelco) continues to anchor the eastern edge, while Ancaster Business Park and Waterdown support advanced manufacturing and professional services with corporate cafeterias.
Locke Street South and the James Street North arts district anchor a strong independent cafe renaissance, with small-batch roasters and brunch spots multiplying. Downtown supports a dense restaurant cluster around King William Street and the International Village.
McMaster University, Hamilton Health Sciences, and Mohawk College drive a large research and clinical employment base. McMaster Innovation Park hosts a growing cluster of biotech and engineering tenants, and Westdale cafes run on student and faculty traffic.

FAQ
23 answers covering response time, pricing, parts, installation, and the Hamilton service area.
Updated August 2026
Yes. We service Rex-Royal machines in Hamilton regularly, current and discontinued models alike. We're an independent service provider, not affiliated with Rex-Royal, which means we'll work on any Rex-Royal machine regardless of warranty status, age, or where it was bought.
Yes. Off-hours service runs on a priority basis with a small surcharge that we mention before dispatch, not after. Most of our weekend and evening Hamilton calls are hospitality operators who can't take downtime during business hours.
Yes. Trucks carry the Rex-Royal wear parts we replace most (seals, gaskets, common solenoids, milk system O-rings, basic sensors). Anything less common ships overnight from the distributor network and is generally in hand within 1 to 3 business days.
Downtown Hamilton, Westdale, Dundas, Ancaster, Stoney Creek, Waterdown are inside our regular Hamilton Rex-Royal rotation, and the rest of the city is on request. If you're at the city edge, call us with your postal code for a quick coverage check.
Yes, scheduled to your actual daily volume rather than a one-size-fits-all calendar. High-volume machines get quarterly visits, lighter-use machines run twice a year. Each visit covers descaling, brew unit service, milk system sanitation, and calibration.
Yes. Every Hamilton installation includes operator training on daily cleaning, basic troubleshooting, drink programming, and what to watch for. After a repair, the technician walks your staff through what was fixed and what to monitor in the coming weeks. Refresher training is available on request.
Flat rate for the visit, with parts billed separately. The invoice line-items everything, so you can see exactly what the visit cost and why. Bigger repairs get a written quote on-site before we proceed.
Then you're our typical Hamilton customer. Out-of-warranty Rex-Royal machines are the bulk of our service work, and they get the same treatment as anything else: real diagnostics, genuine parts where it matters, flat-rate visit with parts billed separately.
No, we don't require contracts. Some customers run on scheduled maintenance because it pays back through machine longevity. Plenty of others call only when something fails. Both paths are fine with us.
Manufacturer warranties typically restrict who can service the machine without affecting coverage. Try the Rex-Royal authorized network first. If they're days out or won't cover the issue, call us and we'll service it on our standard flat-rate pricing.
Business customers in Hamilton are billed on a monthly statement, payable by e-transfer, cheque, ACH, or credit card. First-time work is typically invoiced on completion, with terms shifting to net billing once the account is established.
Yes, and the per-machine cost typically drops once we're already on-site. Common for Hamilton office buildings with multiple floors, hotel groups with several locations, and restaurant groups. Tell us how many machines and where when you book.
When the repair gets close to half the cost of a refurbished replacement, or the machine is past 10 years of heavy daily use with multiple major systems failing, replacement usually wins. We give honest math on the trade-off rather than chasing a repair that's about to need another one.
Yes. Rex-Royal platforms the authorized network has stopped supporting are a regular part of our week. Parts no longer in production come from refurbisher networks, decommissioned-unit salvage, or aftermarket equivalents where the spec genuinely matches.
No. We're independent specialists, not authorized or certified by Rex-Royal or its parent group. Hamilton operators call us anyway because we know the platform, quote transparently, and accept machines the authorized service network declines.
For most Rex-Royal calls in Hamilton, yes. If the fault needs a part we don't carry on the truck, we diagnose on the first visit and return the next business day to finish the repair.
Yes. A Hamilton installation covers the site survey, power and water assessment, water filtration spec, plumbing and electrical hookup, calibration, drink profile programming, and staff training. Multi-unit hospitality and office rollouts are regular work for us.
OEM wherever the engineering matters: brew unit, control boards, sensors, pumps. For commodity components where industry-standard equivalents are at parity, we use those when it saves you time or money. Every part choice is line-itemed on the invoice.
Same day or next business day on-site response is standard for Hamilton calls. Hospitality and high-volume operators get priority dispatch. When you book, we confirm a firm arrival window, not a vague "sometime today" promise.
Yes. Hard to very hard, 140 to 180 mg/L CaCO3 typical from the Hamilton municipal supply (Lake Ontario sourced via the Woodward water treatment plant on Hamilton Harbour) That water profile drives your descaling interval and your boiler element's life expectancy. We test on-site, spec a cartridge or softener sized to your daily volume, and install or service it as part of regular maintenance.
Yes. Hamilton hospitality accounts (hotels, restaurants, cafes, QSR) get priority dispatch and a contact who knows your machines. Scheduled maintenance lands in your slowest service window, and emergency calls during peak hours jump the queue.
Downtown Hamilton core, Stoney Creek industrial area, Ancaster Business Park, McMaster Innovation Park are where most of our Hamilton Rex-Royal work happens. Office buildings, hotel F&B, restaurants, and QSR locations in these areas keep us on the road across Hamilton.
For Hamilton calls the model is the one we use everywhere: flat rate for the visit, parts billed separately. Smaller repairs go straight to the invoice. Bigger jobs get a written quote on-site, and we wait for your okay before we start.
