Frequently Asked Questions
Do you work on high-rise or hard-to-access façades?
Yes. We select the appropriate access method: water-fed pole, MEWP, BMU cradle or rope access to clean safely and efficiently.
Will window cleaning disrupt our operations?
Not at all. External windows can usually be serviced during the day. Internal glazing is typically completed outside trading hours to minimise impact.
Are your methods suitable for older or sensitive finishes?
We assess frame and glass types and choose methods that protect coatings, seals and surrounding materials.
How often should commercial windows be cleaned?
Frequency depends on location, exposure and presentation standards. We can recommend an interval after the site visit.
Is this available as a standalone service?
Window cleaning is delivered as a specialist add-on for ACS contract clients. If you require a standalone service, we can advise on the best route.
