Window Cleaning Cost Estimate: Per-Window vs. Per-Pane Pricing

Window cleaning pricing splits into two common models — per window and per pane — and picking the wrong one for a given house is a common way cleaners either underquote a heavily-paned home or overquote a simple one.

How much should you charge per window?

Most window cleaners charge $10 to $18 per window, or $4 to $8 per pane for windows with multiple panes — a full residential job typically totals $150 to $450, averaging around $260. Per-pane pricing is the more accurate model for older homes with divided-light windows, where a single "window" might have six or more individual panes.

What should be quoted as an add-on rather than bundled in?

Screen cleaning adds $2 to $5 per screen, and track/sill cleaning adds $1 to $3 per window — some cleaners bundle these into their base price and some charge separately. Whichever you choose, state it explicitly on the estimate; "windows cleaned" means something different to every customer until the scope is spelled out.

How much more does interior-plus-exterior cost?

Cleaning both sides of the glass runs 1.8x to 2.0x the exterior-only rate — not double the line-item price, since setup and access overhead don't fully duplicate. This ratio is useful to quote directly rather than pricing interior and exterior as two separate flat rates that don't account for the shared setup time.

How does commercial pricing differ from residential?

Commercial and storefront window cleaning is typically priced at $0.50 to $2.50 per square foot or $6 to $20 per window — a different model than residential, driven by larger uniform panes and repeat contract work rather than one-off jobs. If you serve both markets, keep the pricing structures clearly separate rather than trying to force one rate card to cover both.

Window count, pane style, and screen condition are usually visible from a few exterior photos of the home. Fast Snap Pro turns those photos into a priced estimate built from your own per-window or per-pane rates plus add-ons, so you can respond to a lead fast and confirm the count on-site before finalizing.
