Pure Water Window Cleaning

I've been using Pure Water window cleaning for a number of years. Andy has been fantastic. We agreed on a clean once every 6 weeks and it has proved perfect for us. Pure Water are regular as clockwork and drop an invoice through the letter box if we aren't in. We pay online which makes life really easy for us. We have 2nd floor flat which does make it a challenge but the system Andy uses works faultlessly and produces a great finish despite the reach required. Many thanks
