Post-Construction Cleaning Phases for Durham Builders

Why phases matter

Construction dust keeps settling for days after the trades leave, and new dust is created every time a trade returns to fix a deficiency. If you book one big clean and then a trade sands a wall, the clean has to be redone. Phasing the work means each clean happens when it will last.

Phases also help the general contractor manage access. Cleaners work in areas the site supervisor has released, without getting in the way of trades still working elsewhere.

Phase 1: rough clean

The rough clean happens once major construction in an area is finished, usually after drywall, painting and most finishes are in, but before final fixtures and flooring are protected or revealed. The goal is to remove the bulk of dust and leftover material so the space can be inspected and the final trades can work clean.

Tasks typically include removing loose debris to the site's bins, vacuuming and sweeping floors, wiping down framing, sills and ledges, and removing large stickers and packaging. Bulk debris removal and disposal bins are normally the contractor's responsibility; the cleaning crew handles what is left after the trades.

• Loose debris to site bins
• Floors swept and vacuumed
• Sills, ledges and ledges at height wiped
• Packaging and large labels removed
• Windows and frames rough-cleaned

Phase 2: final clean

The final clean happens after all trades are finished and before the owner's walk-through or handover. This is the detailed clean that makes the space ready to use. Every surface is cleaned from top to bottom: light fixtures, vents and diffusers, walls and doors, cabinets inside and out, glass, washroom fixtures and floors.

Fine dust is the main challenge at this stage. Vacuums with HEPA filtration capture fine particles instead of blowing them back into the air. Floors are cleaned according to their finish, and any protective films are removed.

• High dusting of fixtures, vents and ledges
• Walls, doors, frames and hardware wiped
• Cabinets and millwork cleaned inside and out
• Interior glass and window frames cleaned
• Washroom fixtures and partitions cleaned
• Floors cleaned to suit the finish

Phase 3: touch-up clean

Between the final clean and opening day, deficiency work and furniture delivery almost always create more dust and marks. A short touch-up clean right before occupancy, sometimes called a puff or sparkle clean, takes care of this so the space is presentable on day one.

Booking the touch-up at the start of the project, rather than scrambling for it later, is one of the easiest ways to keep handover on schedule.

Ontario safety rules on construction projects

When a cleaning crew works on an active construction project in Ontario, the Occupational Health and Safety Act and O. Reg. 213/91, the Construction Projects regulation, apply. The constructor is responsible for site safety, and every worker on the project, including cleaners, must follow the site's rules. The regulation requires workers on a project to wear protective headwear and protective footwear, and the site may require other equipment, such as high-visibility vests, eye protection or hearing protection.

Expect a site orientation before the first shift, sign-in and sign-out procedures, and restrictions on which areas the crew can enter. Cleaners should never enter an area that has not been released by the site supervisor.

Dust and designated substances

Construction dust can contain crystalline silica from concrete, drywall compound and masonry. Silica is a designated substance under Ontario's O. Reg. 490/09. Practical controls for cleaners include using HEPA vacuums rather than dry sweeping fine dust, wetting methods where suitable, and respiratory protection where the site's assessment calls for it.

Asbestos is a separate issue. Work that disturbs asbestos-containing materials on construction projects is governed by O. Reg. 278/05 and must be done by qualified workers under strict procedures. A post-construction cleaning crew should not clean up suspected asbestos debris; if it is found, work in that area stops until the constructor deals with it.

Scheduling tips for Durham projects

Durham has steady commercial construction, from new employment space in Seaton in north Pickering to plazas and fit-outs in Ajax, Whitby, Oshawa, Courtice and Bowmanville. On these projects, the most common scheduling problem is booking cleaning too late, after the occupancy date is fixed.

A simple approach is to put all three phases in the project schedule at the start: the rough clean after finishes, the final clean before the owner's walk-through, and the touch-up the day before occupancy. Tell the cleaning company the square footage, the number of washrooms and the finish types so the quote matches the work.

Who does what

Clear responsibilities prevent the most common disputes at handover. The general contractor is normally responsible for site safety, bulk debris removal, disposal bins and fixing deficiencies. Trades are responsible for cleaning up after their own work, such as paint drips or caulking residue. The cleaning company handles the phased cleaning of the finished space. The owner or tenant decides the occupancy date and signs off on the final result.

Write these responsibilities into the cleaning quote. For example, state that the cleaner will remove construction dust and small debris, but not bulk waste, paint overspray or adhesive that needs a trade to remove.

Floors, glass and finishes

New floors need the right treatment from the start. Some resilient floors need an initial scrub and finish before use; sealed concrete and tile need dust removal and a neutral cleaner; carpet needs vacuuming with a machine that can handle fine dust. The flooring supplier's care instructions should guide the first clean.

Glass collects stickers, paint specks and adhesive. These need careful removal with the right blades and solutions so the glass is not scratched. Stainless steel, millwork and new fixtures also have protective films and labels that should be removed carefully during the final clean, not torn off during the rough clean.

Common mistakes

The most common mistakes are booking the final clean before all trades are finished, dry-sweeping fine dust so it settles again, using abrasive pads on new finishes, and forgetting areas that are easy to miss, such as the tops of door frames, inside cabinets, light lenses and HVAC diffusers.

Another is skipping the touch-up clean. Furniture delivery and last-minute fixes almost always leave marks, and a short clean the day before occupancy makes a big difference to how the space looks at handover.

What to send when you ask for a quote

A cleaning company can only price phased work accurately with the right information. Send the total square footage, the number of floors, the number of washrooms, the main floor and wall finishes, how much interior glass there is, and the target dates for each phase. Mention any site rules that affect the crew, such as working hours, parking, elevator booking or a required orientation. With that, the quote can show a price for each phase, so you can see what each one costs and schedule them separately.

After handover

Once the building is open, a regular cleaning program takes over. For new space in Durham, see commercial cleaning in Pickering, commercial cleaning in Bowmanville and our other city pages, or start with post-construction cleaning.
