Commercial Window Cleaning FAQs

Commercial window cleaning/washing refers to the service of window cleaning primarily for buildings of businesses or other establishments.


The key difference between this and normal window cleaning is that this service does not cover domestic properties.

It's easy to think that professional window cleaning is expensive, but it will actually save you money in the long run.


The longer you wait to have your windows cleaned, the more expensive it will be.


With regular cleanings and inspections from a professional company like ours, we can help keep those costs down!

The time taken to complete the window cleaning job depends heavily on the size of the building.


In this sense it is hard to give an accurate estimate of how long it will take.


If you give us a call and describe the job, we will be able to give you a quote of both the price and the time it should take to complete.

When you organise regular contracted window cleaning, we stay in constant contact with you so you are always aware when your cleaning service is due.

Our teams of window cleaners have access to hand held PDA’s which inform the client of any schedule updates and allows contact between the client, the window cleaners and our head office.

It is important for commercial properties to clean their windows more often.


For retail spaces and restaurants, the frequency of window cleaning should be at least once every month because dirt builds up quickly which can make it difficult to maintain a professional appearance.


At the very least, windows should be cleaned throughly twice a year for office buildings.
