Post-Construction Cleaning in Pointe-Claire and the West Island: A Guide for GCs and Tenants

Post-construction cleaning in Pointe-Claire and the rest of the West Island is usually done in three phases: a rough clean once drywall and major trades finish, a final clean before the acceptance walk and a touch-up after the last deficiencies are corrected. For commercial fit-outs in the area's office parks and industrial buildings, the plan also has to cover silica and drywall dust under CNESST rules, the question of whether any phase falls under the CCQ's jurisdiction and, from November on, the salt and slush that winter brings onto new floors.

Why the West Island has its own rhythm

Pointe-Claire, Dorval, Kirkland, Beaconsfield and Dollard-des-Ormeaux hold a large share of Greater Montreal's suburban office, light industrial and life sciences space, mostly along the Highway 40 and Highway 20 corridors and around the airport. Much of that stock dates from the 1970s to the 1990s, which means a steady stream of tenant improvement projects: offices converted to labs, warehouses fitted with mezzanines, retail units reconfigured around CF Fairview Pointe-Claire.

Those projects share a few features that shape the cleaning plan. Tenants often move in on a fixed date tied to a lease, so the cleaning window is short. Buildings are frequently occupied by other tenants during the work, so dust control matters beyond your own unit. And many West Island companies operate bilingually, so cleaning reports and deficiency lists may need to be ready in both French and English.

The three phases, applied to a commercial fit-out

Phase 1: rough clean. After drywall sanding, ceiling grid and major mechanical and electrical work. The crew removes bulk debris, vacuums surfaces with HEPA equipment, cleans out window tracks and wipes down the first layer of dust from frames and sills. Doing this before flooring goes down protects the new floor and keeps dust from being ground into it.

Phase 2: final clean. After flooring, millwork, fixtures and paint. Every surface gets cleaned: ceiling diffusers, light fixtures, cabinet interiors, glass, partitions, doors and hardware, washrooms and kitchenettes, then floors. Labels and stickers come off glass and fixtures, and protective films are removed. This is the clean that should be finished before the acceptance walk.

Phase 3: touch-up. After trades come back to correct deficiencies, they leave fresh dust and fingerprints behind. A short touch-up visit right before move-in fixes that.

For a deeper look at how the phases fit together, see our 3-phase post-construction cleaning standard.

The acceptance walk under the Civil Code

In Quebec, the end of a construction contract revolves around the acceptance of the work, the réception de l'ouvrage under the Civil Code of Québec. The client accepts the work with or without reservations, and the reservations become the deficiency list the contractor must correct.

Cleaning has a direct effect on that list. A space that still has dust on diffusers, paint on glass and film on fixtures generates reservations that have nothing to do with construction quality. Schedule the final clean so it ends a day before the walk, not the morning of.

Dust control and CNESST

Construction sites in Quebec are governed by the Safety Code for the construction industry, under the CNESST. Two issues come up constantly on renovation work.

Silica. Cutting or grinding concrete, masonry and some tiles releases respirable crystalline silica. Quebec sets an exposure value for it, and the CNESST has made silica a priority on construction sites. Cleaning crews that dry sweep concrete dust are exposing themselves and everyone nearby. HEPA vacuums and wet methods are the right tools.

Drywall dust. Not as dangerous as silica, but very fine and very persistent. It migrates into HVAC systems and settles for days. A temporary filter on return air grilles during sanding, replaced before handover, saves a lot of cleaning. Vacuums without true HEPA filtration blow much of that fine dust straight back into the room.

In occupied buildings, the GC should seal the work area with poly barriers and maintain negative pressure where possible. The cleaning crew should not open those barriers until the dusty work is finished.

The CCQ question

Quebec's construction industry is regulated by the Act respecting labour relations, vocational training and workforce management in the construction industry, often called Loi R-20, and administered by the Commission de la construction du Québec (CCQ). Construction work under R-20 has to be done by workers holding the right competency certificate.

Cleaning raises a recurring question: is site cleaning during construction considered construction work, and if so, who can do it? The answer depends on when the cleaning happens, what it involves and who employs the workers. Before you award the contract, ask the GC how they handle it on their sites, and if there is any doubt, confirm with the CCQ. Getting this wrong can lead to penalties for the contractor and delays for the project, and it is much easier to settle before work starts.

Winter projects: what changes in November

Many West Island fit-outs are timed to finish before year-end. That puts the final clean in late November or December, and winter brings its own issues.

• Salt and slush. Trades walking in from the parking lot track salt and calcium onto brand-new floors. Put down floor protection and entrance mats until the touch-up phase, and use a neutral cleaner or salt neutralizer for the final floor clean.
• Temporary heat. Propane heaters add moisture to the air, which can leave condensation on windows and slow the curing of floor finishes. Coordinate floor finishing with the GC's heating plan.
• Exterior windows. Washing exterior glass in freezing weather is often impractical. Many projects defer exterior glass to spring and put it in writing.
• HVAC start-up. When the permanent heating system starts for the first time, it can push construction dust out of the ducts. Plan the final clean after the system has run for a few days if possible.

Frequently asked questions

How long does post-construction cleaning take for an office fit-out?

It depends on size and finish level, but a final clean on a typical office suite of a few thousand square feet often takes one to three days with a full crew. The rough clean and touch-up add shorter visits before and after. Larger or more detailed spaces, such as labs, take longer.

What is included in a final post-construction clean?

A final clean covers every surface from ceiling to floor: diffusers, light fixtures, walls, glass, frames, doors, cabinets inside and out, washrooms, kitchenettes and floors. It also includes removing labels, stickers, protective films and paint or adhesive residue. The goal is a space ready for the acceptance walk and move-in.

Does post-construction cleaning in Quebec require CCQ workers?

It depends on when the cleaning takes place and what it involves. Some site cleaning during construction can fall under the construction industry rules administered by the CCQ, while cleaning after the work is delivered is generally treated as building maintenance. Confirm with the GC and the CCQ before awarding the contract.

When should the post-construction clean be scheduled?

Schedule the final clean to finish at least a day before the acceptance walk, after all trades have left the space. Book a short touch-up visit after deficiency corrections and before move-in. Booking a few weeks ahead helps, especially before year-end when many projects close at the same time.
