What to measure before you ask for a price
Count the glass you actually want cleaned, not every pane on the elevation drawing. Street doors, the reception wall, and the boardrooms may be the whole complaint. Upper floors that nobody sees from the sidewalk can sit on a longer cycle. Commercial window cleaning cost follows that choice. A building-wide number with no priority list is how the entry still looks tired after the invoice.
Note obstacles. Desks against glass, furniture that cannot move, and film or manifestation patterns all slow a visit. Exterior work needs the sidewalk or the setback, a water source if the method uses one, and a time when spray will not hit pedestrians or a tenant intake. Professional window cleaning services should ask those questions. If a quote does not, it is incomplete.
Interior commercial windows cleaning on a partition grid can be done with the office program when it is only fingerprints. A full wipe of both sides, tracks included, is a slower visit and should be scheduled when rooms are free. Tell us if a tenant has a rule about ladder marks or pure-water only. The method can follow the rule. It cannot follow a rule you mention after the glass is done.
After a fit-out, do not buy a maintenance cycle to remove paint specks and stickers. That is a post-construction task. Once the glass is actually clear, the maintenance frequency on this page is the right tool.
If your sites are in more than one city, keep the access notes per building. A pole that works on a low retail front does not become a plan for a tower. The city pages mention local glass requests. The specification still starts with the pane and the way it is reached.
