We Use the Reach & Wash 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, through the water fed pole and onto your glass and dries to a perfectly fine finish and is very eco friendly.


  • 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."
