Cleaning windows at height: step-by-step guide and tips for a streak-free result

With ground-floor windows, a short washer and squeegee let you reach every corner easily. Once windows are on the first or second floor, or above a bay window, accessibility becomes a problem. Moving a ladder for every window takes time and involves risk. With an extendable telescopic pole from High-Clean, you work from the ground more comfortably and safely than with a ladder.

Step-by-step guide: how do you clean windows at height without a ladder?

1. Choose the right telescopic pole and extend it. Every High-Clean telescopic pole has an integrated green water hose, allowing you to work immediately with a continuous water supply and without buckets.
2. Wash the window. Attach the washer and squeegee set and treat the glass with a cleaning product such as Super Window Cleaner 1L, which dissolves grease and deposits.
3. Squeegee the window dry. Move the squeegee from top to bottom in one smooth motion.
4. Finish the edges. Remove excess water around the frames with the 600GSM drying cloth, preventing droplets at height from drying before you notice them.

This order prevents soap residue from drying before it has been removed. That matters even more at height because making corrections is less convenient than with a window within easy reach.

Streaks usually occur because the water dries too quickly or because tap water contains limescale and other minerals. This is particularly noticeable at height because returning to touch up the glass is more difficult. High-Clean offers two solutions from its water softener collection:

• The HCWS528 Water Softener softens hard water through ion exchange and removes limescale, allowing windows to dry without limescale streaks. One cycle softens up to 1,000 litres of water, and the resin beads are easily regenerated with table salt.
• The Pure Water HCPW557 goes one step further: it filters tap water through deionisation to produce 100% pure water, comparable to reverse-osmosis water. It removes not only limescale but also salts and other dissolved minerals, producing an even cleaner, completely streak- and spot-free result on large glass surfaces and solar panels.

Do you prefer the simplicity of softened water, or do you want the best achievable result at height? In the latter case, the Pure Water HCPW557 is the logical next step.

How do I clean windows at height without a ladder?
With a telescopic pole and a washer and squeegee set, you can clean high windows from the ground. Extend the pole to the required length, wash the window and then use the squeegee to dry it.

Which telescopic pole is best for windows at height?
For the highest windows, the 3K Full Carbon telescopic pole is the most comfortable because it is the lightest and bends the least. For lower windows and occasional use, the Aluminium version is sufficient.

What is the difference between using a squeegee and wiping windows?
Using a squeegee means removing water from the glass with a chamois or squeegee. Wiping is the more conventional household method using a cloth, usually for smaller windows within reach.

Does a water softener prevent streaks when cleaning at height?
Yes. The HCWS528 Water Softener softens hard water so it dries without limescale streaks. This is especially noticeable on large windows at height, where water remains on the glass longer before evaporating.

What is the difference between Water Softener and Pure Water?
The HCWS528 Water Softener removes limescale from water. The Pure Water HCPW557 goes further, filtering out salts and other minerals through deionisation until the water is 100% pure. This produces an even cleaner, completely streak-free result on large glass surfaces and solar panels.

Can I use the same telescopic pole on other surfaces?
Yes. With other attachments from the Brushes & Attachments collection, the same telescopic pole can also be used for solar panels, façades or gutters at height.
