Using the newest technology and methods of window cleaning in the business, we achieve our Pure Water through 5 stages of filtering to make sure your windows are immaculate. Although tap water looks clean, in fact it actually contains many dissolved chemicals and minerals. It is these minerals, mainly calcium and magnesium, that leave spotty white residues on glass. We use Pure Water which contains none of these. ​ Daily testing ensures the purity of our water by using a TDS meter (total, dissolved solids). The water that comes out of my tap at home has a reading of 281. For water to dry clear & spot free we need to bring this TDS reading down to 000. Our custom filters are designed to do this, allowing me to guarantee my work 100%. ​ Our process includes using a telescopic pole and a soft brush. Firstly we scrub the frames and glass, then we lift the brush off of the window and starting at the top of the frame rinse the dirty water off with our Pure Water. Now your frame & glass are drying with 100% pure water, which will leave your windows spotless. ​ Price info As houses come in all different shapes and sizes these prices are meant as a guide. Having said that, 9 out of 10 times they are spot on. We will always confirm the quote with you before starting work. ​ Sorry we don't offer a one-off window cleaning service. For your first clean only there is a one off charge to cover the additional time taken on the initial clean, this varies with house size and frequency of ongoing cleans, this will be explained.
