Two ways window cleaning gets priced

Most solo window cleaners price a job one of two ways: per pane (what the calculator above uses, and the standard unit in this trade), or a flat house price once you’ve cleaned enough similar homes to quote from experience. Per-pane pricing is the more defensible starting point because it scales naturally with home size.

What actually moves the price

Scope is the biggest lever — exterior-only is a straightforward outside pass, while interior-and-exterior effectively doubles the work per pane. Access difficulty is the second: ground-floor windows with clear access are the baseline, while hard-water staining, mineral deposits, or tall/steep second-story windows all add real time.

Screens and storm windows the calculator doesn’t model directly are standard add-ons in this trade — quote them separately rather than folding them into the per-pane rate, since removing, cleaning, and reinstalling a screen is its own small job.

The hourly cross-check

If a per-pane price feels off for a specific home, the hourly cross-check ($40–$70/hr) is the sanity check: multiply your estimated time by your target hourly rate and compare. Most solo cleaners eventually stop needing the cross-check because they’ve cleaned enough similar homes to quote from memory.

Recurring vs. one-off pricing

Seasonal or quarterly recurring customers are worth pricing slightly below a one-off job — you’re trading a small discount for predictable revenue and no re-marketing cost. A first clean for a new customer is often priced at the “hard access” tier even if future visits will be standard, since the first pass typically has more buildup to remove.
