Property manager’s field guide · Toronto & GTA
A useful high-rise glass cleaning plan identifies the facade materials, the approved cleaning method, safe access and what happens when a defect is found. For a high-rise property manager, the goal is a clean building with a reliable maintenance record, rather than a wash that leaves the same stains or leaks unexplained.
01 / Define the work
Know what is on the facade before choosing a cleaner
A curtain wall can include clear vision glass, opaque spandrel panels, coated glass, aluminium framing, gaskets and sealants. One cleaner or pad may not suit every surface. Assemble the original care instructions, product information and warranty conditions before asking contractors to price the work.
Identify what the contract includes: glass only, accessible framing, interior faces, exterior faces or particular elevations. A bid for routine dirt removal is different from stain restoration or post-construction cleaning. Paint, mortar residue and metal runoff should be identified as separate conditions, not left for the crew to discover halfway through the job.
Make a test area part of the scope
Ask the contractor to demonstrate the proposed method on representative surfaces and record the products used. Include different glass constructions or coatings where the building has them. Judge the result in daylight and from a practical viewing position after the surface dries.
Routine glass cleaning generally begins with clean water, a compatible mild cleaning solution and non-abrasive tools. The method needs enough lubrication to lift dirt without dragging grit across the glass. Metal blades and abrasive pads should not become routine tools for a mark that resists washing. Coated surfaces may have additional restrictions.
02 / Before mobilisation
Check Ontario access documents before work starts
For suspended window-cleaning access, Ontario’s access and fall-protection guidance assigns responsibilities to the building owner as well as the contractor. Relevant records include a roof sketch identifying suitable anchor points and related structures, inspection and repair records, and the contractor’s written work plan based on the sketch. Defective anchors must not be used.
Roof sketch
Suitable anchor points and related structures identified for the proposed suspended access.
Inspection history
Anchor inspection, modification and repair records available for review.
Written work plan
The contractor’s site-specific plan, based on the roof sketch for the relevant access method.
Ask the contractor to explain how its access method fits the building and what records it needs before mobilising. A proposal that merely says “rope access” or “swing stage” is not a site-specific plan. If a lift or another method is proposed, confirm the site arrangements and applicable requirements for that method. The property team should coordinate the process without improvising rigging or approving technical substitutions it is not qualified to assess.
03 / One brief for every bidder
Give bidders the same information
A comparable facade-cleaning quote should cover the items below. Tick each item as you include it in your brief. This is a scope reminder, not an access approval or compliance certificate.
Ticks stay on this page only and are not saved or submitted.
Where a new access technology is proposed, ask for the same evidence. A promotional demonstration of drone washing does not establish that its spray method, clearances or public-protection arrangements are suitable for your building.
Set a curtain wall maintenance schedule by exposure and results
Use the facade’s care requirements and previous records as the starting point. Road residue, nearby construction, birds and different sun or rain exposure can affect individual elevations. Toronto buildings may also need access and weather planning around freezing conditions.
Review the outcome after each visit rather than applying one interval to every building. Record where deposits return fastest, whether runoff is coming from another material and whether any area needs a different maintenance approach. Cleaning frequency should address the observed condition and product requirements, not conceal an unresolved source of staining.
04 / Record → refer → follow up
Turn observations into a useful defect log
Give each issue an identifiable location: elevation, floor and panel reference. Include dated photographs, the method used and whether the mark remained after cleaning. Record who received the report and the agreed next action.
A curtain wall inspection may require specialist access, testing and assessment beyond the cleaning contract. Cleaning observations help locate issues but are not an engineering assessment.
Coordinate repairs without losing the maintenance history
Tell tenants which entrances, windows or outdoor areas will be affected and how weather delays will be communicated. Keep security, access bookings and the contractor’s site contact aligned. Where repair access can be coordinated with cleaning, document the separate scopes and responsibilities.
For cracked, fogged or leaking units, contact Glass Repair Canada about high-rise glass assessment and replacement. Send the panel references and maintenance photographs with the building details. Our commercial property-management glass service gives property teams a related route for organising identified glazing repairs while keeping facade cleaning with the appropriate contractor.
Curtain wall cleaning questions
How often should curtain walls be cleaned?
Use the facade’s care requirements, exposure and previous cleaning results to set the schedule. Review recurring deposits by elevation after each visit rather than applying one interval to every building.
Can cleaning remove fog between glass panes?
Cleaning the accessible surface cannot remove moisture or deposits inside a sealed glass unit. Persistent between-pane cloudiness may need an insulated-glass assessment.
Is a cleaning report the same as a curtain wall inspection?
No. Cleaning observations help locate issues. A curtain wall inspection may require specialist access, testing and a glazing, structural or building-envelope assessment beyond the cleaning contract.
Does Glass Repair Canada provide facade washing?
This guide directs facade washing to a qualified cleaning contractor. Glass Repair Canada assesses and replaces high-rise glass units in Toronto and the GTA.
