Why Us?

Window cleaning can consume a major part of your day. Let the Fantastic technicians tackle this chore for you, so you can handle more important tasks or enjoy a fun day with family and friends! You don't even have to be at home - just arrange a key pick-up (for inside window cleaning), reserve a parking spot within 30 metres of your property for the cleaning team's van and provide unobstructed access to the windows. We can guarantee:

  • Green cleaning methods: We use only purified water, which is chemical-free and it doesn't leave any streaks. Moreover, it washes away any previously-used detergents.
  • Insured service: In addition to the service being accredited by the Federation of Window Cleaners, all window cleaning teams are fully-trained and subject to regular quality control.
  • Convenient booking options: We provide window washing on weekends and bank holidays, too!
  • Affordable rates: While our prices are fixed, the time for the service is not. You can also enjoy big discounts, if you combine the service with jetwashing or gutter cleaning.

How is Our Window Cleaning Service Performed?

There are only three steps to streak-free and shiny windows:

Step 1: The technicians arrive in a van, specially fitted with purified water tanks and extendable water-fed poles. The equipment allows the window cleaners to safely reach up to the fourth floor without compromising the quality of the service or disturbing your privacy.

Step 2: Deionised water is pumped through the special brush attachment of the extension pole and sprayed over the dirty window. Then, the professionals agitate any stubborn marks and stains by moving the brush attachment across the window frames and glass panes.

Step 3: Once the dust is scrubbed off, more purified water is sprayed to wash away the dirt. The process also helps create a protective coating on the window surface, which keeps your windows clean for longer. The technician repeats this step if a second wash is necessary, at no extra cost.

Step 4 (optional): You can also opt for inside window cleaning. Provided your windows are PVC, we treat windows of different types and sizes: sash and bay windows, as well as skylights and conservatories. Along with washing the window panes, the cleaners will pay special attention to the sills and frames, as well.

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

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

  • 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: 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.

  • 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.
