Window Cleaning: What to Ask Before Booking

Count the work, not just the windows

A quote for glass alone may differ from one including frames, tracks and screens. Describe internal and external surfaces, approximate sizes, sliding doors, balconies and upper floors. Photos can help the provider assess awkward access before arriving.

Make a separate list for each part

• Interior glass and mirrors.
• Exterior glass, including any coated or treated panes.
• Frames and sills.
• Tracks and flyscreens, with removal and refitting if needed.
• Construction deposits, paint or adhesive requiring a separate assessment.

Explain access and surface constraints

Tell the provider about security screens, locked rooms, furniture, narrow side passages and water access. Ask who will move items and whether weather could change the booking. Upper floors and difficult exterior panes need a provider's safe-access assessment; a resident should not improvise access to make the quote cheaper.

Check the cleaning method

Glass coatings, films and deposits can affect the suitable method. Share care instructions and ask the cleaner to assess scratches or existing damage before work starts. Viridian Glass provides product-care resources; follow guidance for the actual installed product rather than assuming all glass tolerates the same treatment.

Agree on timing and handover

For a home, decide whether pets and occupants can remain in the rooms being cleaned. For an office or shop, coordinate access and customer-facing areas with the manager. Check what happens if external work is postponed and how a missed pane is reported.

At completion, review accessible panes and the agreed tracks or screens. Cleaning does not repair damaged seals, scratched glass or broken fittings. Discuss those separately with an appropriate professional.
