Commercial deep cleaning: the right time, the right reasons, the right results

There is everyday cleaning. And then there is the deep clean — the one that resets everything. Here is when to do it, and why it truly makes a difference.

Deep cleaning vs regular cleaning: the real difference

Regular cleaning keeps your space clean week after week. We vacuum, wash floors, clean bathrooms, disinfect surfaces. It is essential — but it is not enough for everything.

Deep cleaning tackles what is not touched on a daily basis. Walls. Ceilings. Light fixtures. Windows. Inside cupboards. Tile grout. Blinds. It is a complete reset.

A well-executed deep clean is visible and above all palpable. The space smells different, surfaces shine differently, and your employees notice.

5 moments when a deep clean is essential

Between Christmas and New Year’s

This is the most popular moment — and the most logical. The premises are empty, the year is ending, and starting January in an immaculate space has a real effect on team motivation.

Slots fill up quickly across Montreal and the South Shore during this period. Plan ahead.

Before or after construction work

A construction site, even a minor one, leaves a fine dust that infiltrates everywhere: ventilation ducts, electronic equipment, textured surfaces. This dust irritates airways and is difficult to eliminate without proper equipment.

Maria Entretien offers a specialised before/after construction service with HEPA filtration. We take care of everything; you recover your premises clean and ready for use.

During an office move

Key handover, taking possession of new premises, welcoming a new team: it is the ideal moment to start fresh. Under many Quebec commercial leases, end-of-lease cleaning is also a contractual obligation.

Before a corporate event

Grand opening, open house, partner or investor visit: the state of your premises at that precise moment is a direct component of your image. A deep clean 48 hours beforehand, and you welcome your guests in the best possible conditions.

After a wave of illness

A flu that went through the whole team, a stomach bug that knocked everyone out? A deep clean combined with steam disinfection resets the environment and reassures everyone.

Deep cleaning is also preventive maintenance

An unmaintained carpet wears out twice as fast. An unpolished floor loses its resistance. Untreated mould spreads and ends up costing a great deal in repairs.

An annual deep clean is an investment that extends the life of your finishes and protects the value of your premises.

Frequently asked questions

How often should a commercial deep clean be done?

For most businesses, once or twice a year is sufficient — typically at the start of the year and in summer. High-traffic spaces or those subject to strict health standards may require quarterly deep cleaning.

Do we need to be present during the deep clean?

No. We can work in your absence, with secure key handover. All arrangements are defined in advance.
