Count and describe the windows in a way the provider understands. A multi-pane window, patio door and small fixed pane should not be assumed to have the same price.
Make the task list explicit
Record which sides of the glass need cleaning and whether the provider will remove and replace screens. Ask about tracks, sills, frames and any special coatings or films.
Tell the provider about paint, construction residue or mineral marks. These may need separate assessment and are not automatically included in a routine glass clean.
Explain the access
Describe floor level, obstacles, furniture and whether the work is indoors or outside. High windows and exterior work need an appropriate access plan. Do not expect a household cleaner to climb on furniture or improvise a way to reach unsafe areas.
For a condo, check building arrangements for exterior windows and access. The unit owner’s booking may not cover glass managed as part of the building.
Protect finishes and belongings
Share the manufacturer’s instructions for coated glass, films and nearby frames where available. Move fragile items from sills and agree who moves blinds or furniture. Scraping, abrasives and chemical residue removal should be discussed before work begins.
Understand the pricing unit
Providers may quote per pane, opening, property or labour time. Ask how large windows, patio doors, screens and tracks are counted. Confirm the minimum booking, travel charges and taxes.
If interior windows are an extra in a house-cleaning visit, confirm the number and accessible height. The calculator’s optional window allowance is a workload assumption, not a quote for specialist exterior work.
Review the result
Check the agreed glass and surrounding areas in normal light. Report streaking or missed areas separately from scratches, failed seals or damage that cleaning cannot correct.
