Ask ten window cleaners how they work and you will get a mix of answers. Bucket and squeegee. Ladder and chamois. Pole and purified water. All of them leave windows cleaner than they were, but only one gives streak-free results on every visit without touching the glass by hand. That is the pure water system we use across Porthcawl, Bridgend and the wider area. This post explains what it is, why it works, and why it matters if you care about results lasting.
Tap water in South Wales contains minerals, salts and trace metals. Calcium and magnesium are the two biggest culprits. When ordinary water dries on glass, those minerals stay behind as tiny white spots. That is the streak you see when someone has cleaned your car or your windows with a hose and not wiped down afterwards.
Pure water is ordinary water that has been run through three stages of filtration: a carbon filter, a reverse osmosis membrane, and a deionising resin. By the time it comes out of the tank, it contains almost no dissolved solids. That is why it is sometimes called distilled water window cleaning online, although deionised is the more accurate term for the system we use.
When pure water hits glass, it pulls dirt off the surface and runs straight to the ground without leaving residue. No wiping, no rinsing, no streaks. The window dries completely clear in a few minutes.
Traditional squeegee work can match the result on a good day, but it needs perfect conditions: no wind, no direct sun, the right amount of detergent, and a skilled hand. Pure water gives the same result regardless of weather, and it works at heights that would require a ladder to do traditionally.
You can read about how we fit pure water into our standard service on the window cleaning Porthcawl page, and the same method is used for our Bridgend window cleaning round.
Ladder work is the single biggest risk in window cleaning. Most accidents in the trade come from ladders that slipped, were misplaced on uneven ground, or were overloaded. Pure water poles are worked from ground level and reach up to four storeys. For homes in Porthcawl, Bridgend, Maesteg, Pyle, Kenfig Hill or Cornelly, that covers almost every residential property.
For commercial premises and conservatories, the same applies. We use our pole system for conservatory cleaning roofs and for upper-floor office windows because it removes the ladder risk entirely.
Pure water systems need no detergents, no glass-cleaning chemicals, no ammonia and no bleach. The only thing touching your glass is filtered water and a soft brush. That matters for:
It is also quieter, uses less equipment, and leaves nothing behind to rinse off walls or paving. You can see the full approach on our eco-friendly cleaning page.
Nearly. Pure water works on standard glass, UPVC frames, aluminium frames, Georgian bars, leaded lights and most conservatory panels. For very old leaded glass or specialist coated glass, we adjust the method. For stubborn hard water staining that has built up over years, we combine pure water with a restoration treatment first.
If you are unsure whether it suits your property, a site visit is the simplest way to find out. We do these free across Porthcawl and Bridgend.
Pure water cleaning is typically priced the same as traditional cleaning for a regular round. For one-off cleans, there is no real difference in cost. The value comes from consistency: you get the same finish every visit, regardless of weather, and you get it without ladders leaning against your walls.
Our post on 5 signs it is time to clean your windows covers some of the reasons to book a clean in the first place, and any of those signs are fixed by a single pure water visit.
If you want a window cleaner in Porthcawl, Bridgend or the wider South Wales area who uses the pure water method as standard, give us a call or message through the contact page. We will set you up on a regular round, and you can read more about why we started the business on our about page.
Streak-free glass, no ladders against your walls, no chemical smells. That is the whole point of pure water window cleaning, and why we have built the business around it.
