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.

Cleans the Whole of the Window

Using the 'Reach and Wash System' we won't just clean the glass we'll clean your frames and window sills too.

  • 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."
