Most people clean their own windows at some point and end up with the same result: streaks that show up the moment the sun hits the glass. It's not a lack of effort — it's usually the water, the tools, or both.

The hidden problem: tap water

Ordinary tap water contains dissolved minerals that are left behind as the water evaporates, creating the faint streaks and haze you see in direct sunlight. Professional cleaners use pure, deionised water that evaporates without leaving any mineral residue — which is why a professionally cleaned window looks clear from every angle, not just up close.

Technique matters as much as equipment

A proper squeegee pass uses a single continuous stroke with consistent pressure, refreshed and dried between passes. Most DIY attempts use a circular wiping motion with paper towels or cloths, which redistributes dirt rather than lifting it off — that's the smeared look that's worse than not cleaning at all.

Reaching upper floors and skylights safely

For multi-storey buildings, conservatories, and skylights, the bigger challenge isn't the cleaning itself — it's safe access. Our crews use water-fed extension poles and, where needed, certified working-at-height equipment, so every pane gets the same finish without anyone risking a ladder on an upper floor.

Inside and out, glass facades included

Beyond standard windows, we clean full glass facades, conservatories and storefronts — surfaces where streaks or watermarks are especially visible and affect how a building is perceived by visitors and customers.

A simple way to tell if it's time

If your windows look fine from inside but hazy or streaked when viewed from outside in direct light, that's mineral buildup from previous cleanings — not new dirt. A professional clean resets that baseline so future touch-ups stay easier to maintain.
