Window cleaning covers the glass, frames, screens, tracks and sills. Upper storeys are done from the ground with a deionised pure-water pole system, which is both safer than ladder work and leaves no drying marks because the water carries no minerals to leave behind.
Why pure water leaves no streaks
Ordinary water carries dissolved minerals. When it evaporates off glass those minerals stay behind, which is the spotting you get from washing a window with a hose and letting it dry.
A pure-water system runs supply water through filtration and deionisation until effectively nothing is dissolved in it. Applied to glass through a brush head on a telescopic pole, it lifts the dirt, and then the glass is simply left to dry — with nothing in the water, there is nothing to leave a mark.
The practical consequence is upper-storey windows cleaned from the ground. No ladders leaning against gutters, no boots on flowerbeds, and a materially lower risk of somebody getting hurt.
What a window clean includes
Exterior glass on all accessible windows, frames and sills wiped down, screens removed and washed, and tracks cleared of the accumulated grit that stops windows sliding properly.
Interior glass is quoted separately since it needs access and someone home. Most people do exterior only, and it is where the visible difference is.
Tracks are the part that gets skipped and the part people notice most once it has been done — years of grit builds up in there and it is why the window has become stiff.
Pairing it with a house wash
Sequence matters: house wash first, then windows. A house wash inevitably puts residue on the glass, so cleaning windows first means doing them twice.
Every house wash customer is a window customer, and getting both on one visit costs less than two mobilisations. If you are booking a wash, ask for windows to be quoted alongside.
Hard water spotting from sprinkler overspray is a separate problem worth mentioning if you have it — irrigation hitting glass leaves mineral deposits that etch over time and need a dedicated treatment rather than ordinary washing.
How often
Twice a year suits most homes — spring after pollen has finished, and autumn. Once a year is enough for properties with less exposure.
Commercial storefronts want considerably more frequent attention. Glass at the entrance to a business is a first impression, and monthly is common for customer-facing frontage.
Properties near gravel roads or active agriculture accumulate faster than the average and generally want a tighter interval.
