Describe the glass and property
Identify internal and external panes, frames, tracks, screens, coatings, stained glass, storeys, balconies and building rules. Share photos and note access restrictions, nearby landscaping, parking and fragile surfaces. Glass defects or failed seals should be identified before cleaning.
Confirm capability and safe access
Ask which method and equipment will be used and whether the provider has current training, approvals and insurance relevant to that work. Roof, rope, elevated-platform and difficult access require specific assessment; do not assume all specialists perform every method.
Compare scope and quote
Request written details for panes, frames, screens, tracks, timing, weather, access fees and exclusions. Clarify whether restoration, hard-water deposits, paint removal or repairs are included; these may require different methods and are not ordinary cleaning.
Prepare for the appointment
Arrange keys, building access and parking, clear reachable sills and advise of pets or fragile items. Confirm what happens if weather or site conditions make an area unsafe or inaccessible.
