Office Cleaners Who Know Hamilton's Buildings

A Note From the Founder
Hamilton's downtown towers, heritage walk-ups, and Mountain office parks all need someone who knows the after-hours protocols and shows up when the lights go out. That's the work we built this company around.

Office Cleaning FAQs

Both. In a multi-tenant building we run one crew across suites on separate scopes — the third-floor law office can get nightly service while the suite below runs twice a week — and shared lobbies, elevators, corridors, and common washrooms sit on their own line billed to property management. One invoice, one contact for the whole address. Single-suite tenants can hire us directly; we don't need the rest of the building on board.
Rooms wear at different rates, so we split the schedule instead of quoting one blanket frequency. Kitchens and washrooms need nightly attention once you pass roughly 20 staff. Boardrooms need a reset whenever clients have been in — crumbs and coffee rings, mostly. Workstation areas hold up fine on a weekly vacuum and dust. A 15-person suite usually lands at twice-weekly service; a 60-person floor runs five nights a week. The quote breaks it out room by room.
Most office cleaning runs between 6 p.m. and 6 a.m. You issue us a fob, key, or a unique alarm code — never a shared staff code — and the same two or three bonded cleaners use it every visit, so your alarm log shows the same names, not a rotating cast. Arming the system and checking the door is the last item on our sheet, not an assumption. We carry $10M commercial general liability; your property manager gets the COI on request.
We work to a clear-desk rule: exposed desk surface, monitor arms, and chair backs get wiped; papers, keyboards, and anything resting on a document stay exactly where they are. We never stack, move, or 'tidy' paperwork — in legal and accounting suites that's a confidentiality problem, not a courtesy. If you want keyboards and desk phones disinfected, we add it as a listed line item so staff know it's coming. NDAs signed on request.
Yes — fragrance-free is our default in offices, not an accommodation. Your staff walk in at 8 a.m., and a strong 'fresh' smell at 8 a.m. is product residue still hanging in the air — exactly what scent-free workplace policies exist to prevent. We use unscented neutral cleaners and low-odour disinfectants, all WHMIS-labelled, and we'll hand your JHSC or building manager the SDS sheets before the first visit.
We walk the space and count what actually drives cleaning time: washroom fixtures, kitchen size, desk count, boardrooms, the carpet-to-hard-floor split, and interior glass. We also confirm the practical details — alarm procedure, elevator access hours in multi-tenant buildings, and where the janitor closet and water supply are. You get a fixed written quote within one business day. A real person reads every inquiry, so start through the website or call — any time, day or night.
Yes. We get fob or key assignments at contract start, and our crews follow the building's sign-in protocol on every visit. We service suites in heritage buildings and modern multi-tenant towers across downtown Hamilton.
We assign crews by route, so a single team typically covers a few buildings clustered together. For Ancaster and Stoney Creek we run dedicated routes that don't share crews with downtown. Service stays consistent and the same faces show up each visit.
Yes. Clinics across the Mountain and the downtown medical district book us for after-last-patient service, with hospital-grade disinfectant on exam-room and reception high-touch surfaces. We schedule around your closing time so the space is ready before the first appointment.
