Why us?

Cleaning the stains from last night’s rain doesn’t require any action on your part. The specialist will carry everything he needs, water included, to refresh your windows from top to bottom. You don’t even have to meet the team on-site – just reserve a parking space within 30 metres from your property to benefit from a professional window cleaning service that is:

  • Eco-friendly: This external window cleaning procedure will use only purified water, which will absorb all smudges in its path without leaving any streaks behind;
  • Safe: Thanks to the water-fed extension pole, the cleaner can easily reach any windows and sills up to the fourth storey without resorting to ladders or cherry pickers;
  • Convenient: The professional can easily treat sash and bay windows, UPVC French doors, cladding, conservatory roofs, and much more without disturbing your privacy;
  • Reliable: This service is accredited by the Federation of Window Cleaners and we have assigned several quality control managers to ensure each job is done by the book.

How do we perform the cleaning?

The Fantastic technician will arrive with a van that carries a large supply of purified water.

Step 1: The cleaner will start by attaching the extension pole to the water pump.

Step 2: The liquid will be then released under high pressure from a special brush head attachment, which will be moved across the entire window surface to treat all stubborn stains.

Step 3: After repeating this process twice and using the brush itself to scrub off any remaining spots, the specialist will let the water evaporate on its own. This will create a protective condition that will keep your window panes dust- and dirt-free for much longer than any traditional cleaning methods currently in use.

Step 4 (optional): Upon request, the professional can also wash your windows from the inside. For this, the cleaner will use squeegees and purified water and will stay for as much as needed to erase all stains from existence.

The window cleaning service in London is suitable for many types of windows and glass structures, including single & double windows, skylight windows, small bay & big bay windows, conservatories, and more. Besides the panel itself, the specialist will also wash all frames and sills as part of the service, as long as they are PVC.

Frequently asked questions

  • Q: How long will the service take?

    A: It depends on the number of windows and their condition.

  • Q: How many cleaners will come?

    A: We usually send a single technician, but we can dispatch more if necessary.

  • Q: Do you wipe the windows after you clean them?

    A: There is absolutely no need to do so as the purified water doesn’t leave any streaks behind.

  • Q: Can you come after 6 p.m.?

    A: This is not advisable. If sunlight is limited, the technician will not be able to spot all blemishes on the windows and the final result would be less satisfying.

  • Q: How do I cancel my booking for window cleaning?

    A: To cancel your appointment, you need to log into your Fantastic account and go to the dashboard. There you can cancel or reschedule your appointment easily.

  • Q: Can you clean wooden frames and sills?

    A: The equipment ejects water under very high pressure. Because of this, we cannot clean wooden window elements as there’s a high risk of causing damage.

  • Q: Why do you need a parking spot near my property?

    A: The purified water equipment is attached to the van. The cleaner has to park it no further than 30 metres from the property and on the same side where your windows are located.

  • Q: Can I get some kind of deal?

    A: Join the Fantastic Club today and you’ll get so much more than just a discounted price. All members get to benefit from awesome perks like priority bookings for our most wanted time slots and special seasonal deals.

  • Q: Can I make changes to my bookings?

    A: In order to manage your current bookings, you need to log into your Fantastic account. If you don’t have one, you can create a new profile really easy. Once you’ve registered, head over to the dashboard section. There you can apply changes to all of your service appointments.

  • Q: Can you deep clean my frames?

    A: Yes, but only from the inside and only if they are PVC frames. We are not able to deal with paint, plaster or heavy permanent stains.

  • Q: Can you remove mould from my frames?

    A: This is not something we treat.

  • Q: I have a glass banister on the balcony. Can you clean the external part of it?

    A: If it can be accessed from the ground with our reach and wash system, we will clean it. Otherwise, it will not be safe for the technician to do it from the balcony itself.

  • Q: Do you use any detergents when you clean windows?

    A: We use only purified water which does not leave any marks or streaks.

  • Q: Can you remove plaster on the external glass panes?

    A: Only if the windows are reachable from the inside of the property. Otherwise there is no safe way to do this from the outside.

  • Q: What if the weather is bad and it is raining?

    A: It depends on how heavy the rain is. Usually an assessment of the situation is conducted on the day of the service. If the weather is not optimal, the technician will inform you so you can reschedule your service for another day.
