Exterior Window Cleaning in Perth
Outside Glass, Cleaned With Pure Water, Up to Six Storeys
Coates Window Cleaning provides exterior window cleaning across the Perth metro, outside glass, frames and flyscreens on single storey homes, double storey homes and buildings up to six storeys, cleaned from the ground with purified water through water-fed poles so there is no ladder against your render, nobody on your roof and no spots left as the glass dries. It is the method behind every outside clean we do, for homes and for commercial sites, and most customers add the inside while we are there.
What Is Pure Water Window Cleaning?
Because the water contains no minerals or detergent, it dries completely spot-free, with no residue, no streaks and no film for new dirt to cling to. It's the standard method on every Coates Window Cleaning exterior clean across Perth.
Why Pure Water Beats Traditional Cleaning for Outdoor Windows
In plain terms, the glass isn't just cleaner on the day, it stays cleaner for longer. Perth's bore water staining and building dust are exactly the problems this method was built for. If you grew up calling it window washing, this is the modern version, and it works better. It is also why an outdoor window wash with a hose and a squeegee never quite gets there, the hose water carries the same minerals the sun then bakes onto the glass.

How Much Does Exterior Window Cleaning Cost in Perth?
Exterior-only cleans are quoted per home, and they always come in under the full inside-and-out clean, which runs $300 to $600 for most Perth homes with glass, frames and flyscreens included. What moves the price is the number of panes, the storeys and the condition of the glass, not the suburb. Most customers find that once we are set up outside, adding the inside is the better value, and the window cleaning prices page has every published figure.
How Often Should Outside Windows Be Cleaned in Perth?
What's Included
Glass, frames and sills, and on interior cleans, low-toxicity products and traditional methods, worked carefully around your furnishings.
Frames and flyscreens are part of every residential clean for residential jobs, and scheduled programs are available for commercial sites.
What About the Inside?
Pure water is an outside method, the inside is done by hand with low-toxicity products, traditional tools and boot covers on, worked around your furniture and blinds. Most homes book the two together because the inside pass is quick once the outside is done, and the full inside-and-out clean with glass, frames and flyscreens is what the residential window cleaning page covers. Offices and shopfronts get the same split on a schedule, see commercial window cleaning.
Exterior Window Cleaning, Your Questions Answered
Same job, two names. The water-fed pole is the tool, a telescopic pole with a brush head that carries water to the glass, and pure water is what goes through it. Reach and wash is a third name for the same thing. Whatever it is called, the result is outside glass cleaned from the ground and dried without a mark.
Yes, purified water is "hungry" water. Stripped of its minerals, it binds to dirt and lifts it off the glass, then rinses and dries spot-free. It's the same reason laboratories use deionised water for cleaning.
Light mineral staining, yes. Heavy, baked-on bore staining sometimes needs specialised treatment, and we'll tell you honestly at the quote stage rather than promise a miracle on the day.
Safer than traditional methods, because no chemicals means nothing to react with tints, coatings or seals. It's the same reason we use it for solar panel cleaning.
Genuinely, yes, and not in the vague marketing sense. There's no detergent or chemical in the process at all, just purified water, so nothing goes into your garden beds or down the stormwater drain except water. It's the cleanest method there is, in both senses.
Nothing, and that's the whole trick. We take everything out instead, running the water through filters that strip the dissolved minerals until it's completely pure. Pure water grabs dirt on its own and dries without a mark, so there's no detergent, no additives, nothing left on your glass.
Purified water through a water-fed pole, worked from the top pane down and rinsed clean, because it dries without the mineral spots that hose water and tap water leave. If you are doing it yourself, a bucket of clean water and a squeegee in the early morning is the next best thing, and our guide to the best way to clean windows walks through it.
Outside first, it carries most of the dirt. Once the exterior is done, anything still showing is on the inside, which makes the interior pass quick and precise. It's how we work, and it's the right order if you're ever doing it yourself.
With traditional detergent methods, avoid direct summer sun, the solution dries before it can be rinsed and leaves streaks. Pure water is far more forgiving, which is one reason we can work right through a Perth day, though early morning is still kindest on the glass in the middle of summer.
Either. Exterior-only is a common booking for two-storey homes and for commercial glass, and the full inside-and-out clean is what most homes book because the inside pass is quick once the outside is done. Tell us which when you ask for a quote.
