A window cleaning estimate should say which glass surfaces, screens, frames and tracks are included. Interior glass and accessible exterior glass may have different access needs. For a condo, confirm the building’s arrangements before requesting exterior work. Document damaged seals, coatings or glass separately from dirt.
Count the work rather than only the windows
Describe the property and identify sliders, fixed panels, divided panes and unusual shapes. Ask how the provider counts each type. Decide whether you want both sides of the glass and whether screens and tracks are separate tasks. Provide photos of difficult areas without sharing private interior details unnecessarily. A quote built around a clear inventory is easier to compare than two offers that use different definitions of a “window.”
Confirm access and protect surrounding finishes
Clear light items near the glass and explain which furniture must stay in place. Identify coatings, tint, delicate frames and stone sills before work. Exterior access may require permission or a provider equipped for that task; do not assume a household clean includes high-rise work. Ask about water availability, parking and scheduling around other contractors. Share known access limitations early so the appointment is useful rather than spent resolving entry problems.
Inspect glass, tracks and existing damage separately
Review the work in the areas included and distinguish removable residue from scratched glass, failed seals or worn coatings. If a mark remains, ask what was observed before authorizing another method. Check screens and tracks against the agreed scope, since clean glass alone does not show whether those tasks were completed. Keep a record of the service and use actual condition to plan the next visit rather than accepting a universal cleaning interval for every property.

Frequently asked questions
Does window cleaning always include tracks and screens?
No. Those tasks may be quoted separately. Ask for them by name and compare estimates using the same components.
Can cleaning fix cloudy glass between panes?
Clouding between panes may relate to a seal or glazing issue. Ask an appropriate window professional rather than assuming surface cleaning can correct it.
