Commercial cleaning

Our core expertise

Commercial cleaning is GSF’s founding trade, and it remains the centre of gravity of what we do in Quebec. Keeping a building is not simply cleaning it: it requires teams who know the site, written standards per zone, and supervision that actually walks the floors. The cleanliness a tenant, an employee, or a visitor perceives is built on regularity — not on one well-executed visit.

What building managers actually deal with

The requests that reach us look remarkably alike from one portfolio to the next: the service started well, then consistency eroded. The causes are rarely dramatic — a standard that was never written down, a substitution nobody briefed, a zone forgotten because it belonged to no one.

• Expectations understood differently across shifts or floors
• Substitutions starting from scratch because instructions were never passed on
• Border zones (docks, service stairs, indoor parking) with no clear owner
• Complaints handled one by one, without correcting the routine itself

How we read a building

We start by looking at the building the way your occupants experience it: where they enter, what they see first, which zones degrade fastest. That reading produces an order of priority, then a standard per zone — frequency, expected result, timing. Exact scope and follow-up arrangements remain defined in the agreement.

• Site walkthrough and reading of occupancy journeys
• A written standard per zone rather than one global task list
• Intervention windows matched to real occupancy
• A start-up checkpoint, then adjustments documented with you

Day-to-day cleaning

This is the backbone of the service: the same gestures, in the same places, with the same expected result. We favour a routine that reads clearly — one the regular team and a substitute can both follow — over a pile of instructions nobody sustains over time.

• Common areas, lobbies, and visitor journeys
• Offices, meeting rooms, and food areas within scope
• Washrooms: cleaning, restocking, and visual checks
• Circulation areas, stairs, and frequently used touchpoints

Specialized work

Some operations do not belong to the daily routine: they need equipment, preparation, and often a window outside occupancy. They are planned ahead, separately from the routine, and confirmed site by site under the agreement.

• Deep care and restoration of floors according to their material
• Care of carpets and circulation textiles
• Interior glazing reachable without specialized access equipment
• Post-construction or post-reconfiguration clean-up when the agreement calls for it

High-traffic zones

A main entrance, an elevator, or a lobby washroom does not behave like a closed office: it degrades during the day, precisely when the building is most looked at. We treat those zones as a subject of their own, with visits positioned during the day rather than a single end-of-service pass — within the limits of the agreed plan.

• Identifying the zones that degrade fastest in your building
• Maintenance visits positioned during occupancy when the plan allows
• Particular attention to outdoor / indoor transitions in season
• Frequencies tuned to what the field actually shows

Demanding environments

Many buildings include spaces more sensitive than the rest: a treatment room in a service centre, a laboratory on an industrial site, a controlled-access zone. We work there according to the site’s written instructions, in the zones you authorize, with teams informed before their first visit. This page claims no sterile qualification, no sector accreditation, and no proprietary protocol: the applicable framework is the one you define.
