Commercial window cleaning in Ontario for 2026: $2–$8 per pane for storefront and low-rise work, $150–$500 for a typical storefront visit, water-fed pole work at $0.30–$0.80 per square foot of glass, and monthly contracts running 20–30% below one-off pricing. Here's how the rates break down and what actually changes the number on your quote.
Average Window Cleaning Rates in Ontario (2026)
| Service | Typical 2026 rate |
|---|---|
| Storefront pane (out only) | $2–$4 per pane |
| Storefront pane (in + out) | $4–$8 per pane |
| Typical retail storefront visit | $150–$500 |
| Water-fed pole (2–4 storeys) | $0.30–$0.80 / sq ft of glass |
| Post-construction glass cleaning | Priced per job; 2–4× standard |
| Hard-water stain restoration | $10–$30 per affected pane |
| Monthly contract | 20–30% below one-off |
Frequency is the biggest rate lever. Monthly glass is fast glass — no baked-on grime, no restoration surprises — which is why contract clients pay materially less per visit than the twice-a-year callers with the same square footage.
What Affects Your Quote
Access and height. Ground-floor squeegee work is the baseline. Above one storey, water-fed poles keep costs reasonable up to 3–4 storeys; beyond that you're into lifts, anchor inspections, and rope access — a different price category entirely. Interior atrium glass and glass canopies also price by access difficulty.
Pane count and style. Many small divided panes take longer than the same area in large sheets. Doors, sidelites, and transoms count as panes too — an accurate pane count up front prevents quote-vs-invoice friction later.
Condition. First cleans of neglected glass — construction residue, years of hard-water spotting from irrigation overspray, salt etching — run 2–4× a maintenance clean. If sprinklers hit your storefront glass, fixing the spray pattern saves more than any cleaning schedule.
Bundling. Window cleaning shares mobilization happily: pairing it with pressure washing in spring — glass after washing, always — or with storefront detailing gets both services below their standalone price.
The Ontario Seasonal Pattern
Two cleanings anchor the calendar. Post-winter (April): salt film coats every ground-floor pane and corrodes aluminum frames if left; this is the one cleaning even minimal-budget properties should keep. Pre-holiday (November): retail glass gets its highest foot traffic of the year through December. Between those anchors, image-sensitive tenants drive frequency — and glass condition is one of the first things prospective tenants notice on a site tour, right alongside the state of the parking lot.
DIY vs. Professional: The Real Comparison
Staff with a squeegee can keep entry doors presentable, and should. Whole-storefront DIY breaks down on time and finish: streak-free results on large panes are a genuine skill, interior cleaning means moving displays without damage claims, and anything above ground level puts employees on ladders — a workplace-safety exposure no property manager wants for the price of a $200 service visit. Professional crews also carry the insurance that matters when a pane cracks during cleaning.

Frequently Asked Questions
How much does commercial window cleaning cost in Ontario?
Storefront and low-rise cleaning runs $2–$8 per pane (inside and out) in 2026, with typical retail storefront visits landing at $150–$500. Two- to three-storey buildings cleaned by water-fed pole run $0.30–$0.80 per square foot of glass. Monthly contracts price 20–30% below one-off visits.
How often should storefront windows be cleaned?
High-image retail cleans monthly (some food-service and showroom tenants go biweekly); offices typically clean quarterly; industrial properties once or twice a year. Ontario adds a seasonal factor: post-winter cleaning is near-mandatory because salt spray films every ground-floor pane.
What is water-fed pole window cleaning?
A telescopic pole system feeding purified (deionized) water to a brush head — glass is scrubbed and rinsed with pure water and dries spot-free without squeegeeing. It cleans safely from the ground up to about 3–4 storeys, avoiding lift costs and working-at-heights exposure for most low-rise commercial buildings.
Does window cleaning include frames, sills, and screens?
Standard scope is glass plus a wipe of frames and sills; tracks, screens, and hard-water stain removal are add-ons. Post-construction cleaning — removing stucco, paint, and silicone from new glazing — is a separate specialized service priced per job because razor work carries scratch risk.
Can hard water stains and salt residue be removed from glass?
Usually, with polishing compounds or mild acid treatments — priced as a restoration add-on rather than regular cleaning. Left too long, mineral etching becomes permanent and the fix becomes glass replacement, so flag staining early. Salt film from winter is routine and comes off with standard cleaning.
