Window cleaning in Toronto: Plan and Compare Quotes
Window cleaning in Toronto starts with a clear scope: identify the glass, choose interior or exterior cleaning, and ask how the contractor will reach each window. Compare written quotes for the same work. For exterior cleaning, request a wash-water plan that keeps wastewater out of street catch basins. For suspended access, involve building management before booking. [1] [2]
Define the work before asking for a price
Send each contractor the same window list and photos. Identify floors, patio doors, divided panes, removable screens and any glass above a porch or extension. Ask the contractor to explain how they count windows or panes. Specify interior cleaning, exterior cleaning or both, then list screens, sills and tracks as separate items.
Point out paint, adhesive, mineral marks, damaged seals or existing scratches. Ask which marks the contractor will attempt to remove, which treatments require your approval and which surfaces they will exclude. Request a written total with taxes, access charges and optional work identified. Compare property-specific quotes for that agreed scope.
Confirm access and responsibility
Ask the contractor to describe the access method for each elevation: work from the ground, a ladder, a lift or suspended equipment. Request proof of liability insurance and confirmation that the coverage applies to your planned work. Share photos of overhead wires, narrow side passages, locked gates and fragile structures before the contractor commits to a method.
For a condo exterior that requires suspended equipment, contact building management before arranging an individual visit. Ontario assigns building owners duties that include checking anchor suitability, retaining inspection records and providing roof sketches. The employer must prepare a written work plan for suspended-equipment cleaning or sill work. Ask management and the contractor who will provide each document and authorize roof access. [2]
For proposed rope access, ask about worker training, supervision and the site-specific rescue plan. Ontario recommends IRATA or SPRAT training and work practices, while recognizing that alternatives may satisfy the law. Ask the contractor to explain how their training and planned methods meet the requirements for your building. [2]
Agree on exterior wash-water handling
Ask where the contractor expects rinse water to go, especially beside a driveway, sidewalk or street drain. Toronto prohibits outdoor washing wastewater from reaching catch basins. The City explains that washing with water alone can dislodge contaminants, so choosing a soap-free method does not remove the need to manage runoff. [1]
Request a plan that fits the property. Toronto lists evaporation, rerouting away from catch basins and containment as options. The City also describes indoor-drain disposal or off-site hauling, with conditions: indoor disposal may require treatment, and a Ministry of the Environment, Conservation and Parks approved hauler must handle off-site removal. Have the contractor explain the intended method before work starts. [1]
Plan the visit around weather and access
Choose a preferred date and a backup date, then agree on who decides whether conditions allow exterior work. Ask how the contractor handles freezing temperatures, wind and rain, and whether a postponement changes the price or deposit. Use the seasonal chart to discuss contingency plans, then check the forecast for the actual appointment.
Environment and Climate Change Canada reports an average of 0.43 days with a daily minimum temperature at or below 0°C in October, rising to 8.2 in November, for Toronto (City) during 1991–2020. Use these historical averages to discuss colder-weather contingencies. They do not establish a safe cleaning date or predict this year’s weather. [3]
Before arrival, clear access to the windows and move small furniture or breakable objects. Agree on who removes and reinstalls screens. Arrange entry, gate access and pet separation. For a shared building, ask management to confirm the permitted work area and any resident notice arrangements.
Review the result before closing the job
Agree on a walkthrough and a process for reporting missed panes before accepting the quote. Check the included glass from inside and outside where you can do so from a safe position. Review screens and tracks if you ordered them, and confirm that the crew has reinstalled anything they removed.
Record any unresolved marks with photos and ask whether the contractor considers them removable dirt or an existing glass defect. Keep the quote and completion notes together. For another visit, reuse the window list and update the scope instead of assuming the previous price includes additional work.

Local details that affect your job
Toronto catch basins change the exterior-cleaning plan
Before hiring, identify nearby street catch basins and ask how the contractor will prevent cleaning water from reaching them. Toronto’s guidance covers mobile wash operations, including window washing, and assigns responsibility to both the customer and company. A promise to use only water does not address the City’s concern about contaminants removed from surfaces. [1]
Ontario suspended-access rules require building coordination
For exterior cleaning with suspended scaffolds, boatswain’s chairs or similar single-point suspension equipment at a Toronto building, ask management to confirm anchor inspection records and supply the required roof sketch. Ontario requires building owners to arrange anchor inspections at least once a year, as well as in other specified circumstances. The employer must give telephone notice to an inspector in the nearest ministry office before work using this equipment begins. Confirm these arrangements before setting the appointment. [2]
Choose the next step for your windows
| Your situation | Next step | Confirm before booking |
|---|---|---|
| Ground-floor glass you can reach from a stable position | Consider doing the accessible glass yourself or request a limited-scope quote. | Identify the panes and surfaces you intend to clean. |
| Upper-floor glass or obstructed access | Ask a contractor to assess access from photos or a site visit. | Request the proposed method and insurance documentation. |
| Condo exterior requiring suspended equipment | Contact building management before arranging the job. | Confirm roof sketches, anchor records and the contractor’s work plan. |
| Exterior washing beside a street catch basin | Require a runoff-control plan. | Confirm how the contractor will keep wastewater out of the catch basin. |
| Exterior cleaning near colder weather | Agree on a backup appointment. | Ask who decides whether to postpone and how payment terms apply. |

- Set a completion walkthrough and a process for reporting missed work.
Frequently Asked Questions
How can I compare window-cleaning quotes?
Give each contractor the same photos and window list. Ask each to separate interior glass, exterior glass, screens, tracks and stain treatment. Confirm counting methods, access charges, taxes and exclusions before comparing totals.
Can I book exterior cleaning for my condo myself?
Start by asking building management who controls exterior access and authorizes the work. If the contractor needs suspended scaffolds, boatswain’s chairs or similar single-point suspension equipment, Ontario requires building-owner roof sketches and an employer work plan. Confirm those arrangements before booking an individual appointment. [2]
Can rinse water flow into a Toronto street drain?
Toronto says outdoor washing wastewater must not reach catch basins. Water-only washing can still dislodge contaminants. Ask the contractor to explain containment, rerouting or another disposal method that meets the City’s requirements. [1]
Should I schedule exterior cleaning in October?
Discuss the forecast and postponement policy with the contractor. Toronto’s 1991–2020 climate normals record fewer days with a daily minimum temperature at or below 0°C in October than November. These historical averages cannot establish safe conditions or predict the weather for your appointment. [3]
