All of which results in the very minimum disruption to your company while providing very high levels of service and an exceptional standard of cleaning.

Property hazards and risks are always assessed by our team prior to commencing the clean.

Plus we utilise the "Reach and Wash system" without extra change. This ladderless method of window cleaning is as environmentally friendly as it’s possible to get using virtually 100% pure water, pushing dirt away from your windows and sills without the need for chemicals or detergents.

Advantages of the Reach and Wash system

the reach and wash window cleaning system

The reach and wash is a highly effective method which allows us to clean both glass and window frames. The water is taken through five stages of filtration and finally through a fine resin to take out all impurities producing 100% pure water straight from the vehicle. Then it is pumped through the water fed pole onto your glass and dries to a perfectly clear, smear free finish that is totally eco friendly.

Better Health & Safety

Significantly reduces risk of an accident to the window cleaner, your staff and your clients.


Reduces the Risk of Damage

Reduces the risk of property damage caused by ladders - ie sills, slates, tiles, gutters and even to nearby cars.

Cost Saving

For high storeys it saves hiring personal lifting equipment and no time is wasted climbing and descending ladders.


Cleans the Whole of the Window

Using the Reach and Wash system, in addition to cleaning the glass we clean the frames and window sill too.

Put our first class window cleaning to the test, ask us to visit your premises on a trial basis. Entrust us with your commercial window cleaning and we guarantee a perfect window cleaning result. Our 20 years experience, attention to detail and our customer friendly service from professionally qualified staff makes us the right choice for window cleaning every time.


  • I chose Blue Flag from the 'Which? Local' list of recommendations and have been using them for over a year. They come reliably every two months and clean outside and in to a high standard. Peter and his team are honest and helpful, going the extra mile, for example, to clear leaves from my roof drain. Their charges are fair and I consider them very good value for money."
