Window cleaning, with the right method for every window

Clear windows shape how your building looks, from outside and inside. Alpha Facility cleans windows, glass doors, shop fronts and façades. We decide which method gives the best result: traditional or pure water.

Our methods

We choose the method, you see the result

During the site visit, we look at your windows and choose the method. You don’t need to worry about it. We often combine both for the same client.

Traditional method

With an applicator, squeegee and chamois, plus a suitable cleaning product where needed. For indoor and outdoor windows, especially stubborn dirt.

Suitable for

  • Windows, shopfronts and glass doors
  • Grease, limescale and stuck-on dirt
  • Windows after renovation: cement, plaster, paint splashes, silicone and sticker glue.

Pure-water system

Tap water is purified until it contains no lime or minerals. With that water and a telescopic brush we clean only the outside of windows, including high windows, from the ground. It dries without streaks, without soap.

Windows and frames in one go, without a ladder against your façade.

Exterior windows only

  • High windows, reached from the ground
  • Glass façades and large glass surfaces

FAQ

Questions about window cleaning

What exactly is a pure-water system?

An installation that filters tap water until it contains no lime or minerals. Because there’s nothing left in the water, it dries without streaks. With telescopic brushes we can reach high windows from the ground.

Can I choose which method you use?

You don’t have to choose. We look at your windows and pick the method that gives the best result. Often we use the traditional method inside and pure water outside.

Do you need to be inside to clean the windows?

Not for the outside. For the inside, yes; we then agree a time when we can get in.

Do you clean in the rain?

Light rain is usually not a problem with the pure-water method. In heavy rain, storms or frost we reschedule and let you know.

How do I pay?

You receive an ordinary invoice. For household help with service vouchers, contact CS Cleaning Services.
