Why You Should Choose Us

We hold the value of being the most professional and reliable window cleaners in South London above all else. We are friendly, considerate, and love what we do, and this shows in our reviews. We take pride in doing a perfect job every time and take care to respect your privacy when working. We have exceedingly high safety standards that all of us strictly observe, to protect you, ourselves, and your property.

If you would just like a one-time Sydenham window cleaning service, we are very happy to do this. For regular cleans, we always stick to the cleaning schedule you request and guarantee to leave your windows looking perfectly clean. We do offer traditional window cleaning on any ground floor areas if you request it, however, we recommend using our water fed pole reach and wash window cleaning service. This method of cleaning is far more advanced, ensuring a perfect clean with no marks when dry, even on hard to access windows. It is environmentally friendly and helps protect your privacy on higher floors.

This window cleaning system uses purified water, fed through a pole to a monofilament brush head. This allows us to clean even the hardest to reach windows on tall and intricate houses, conservatory roofs, and any other areas of your home that cannot be accessed by ladders. Our laboratory grade, filtered water, is the perfect window cleaning fluid. All contaminants, minerals, and chemicals have been removed, activating the water’s natural solvent properties. This means it will grab hold of, and dissolve, any dirt, grease, or grime, leaving behind nothing but perfectly clean glass. This results in us not needing to use any cleaning chemicals or water softeners that can be harmful to plants and animals, so your garden, pets and property are totally safe in our hands.

Another useful feature of our cleaning system is that we have a portable version that we can carry around the property with us. This system has its own water supply, meaning we can reach the rear of properties that have no easy access, with no need to trail hoses or carry ladders through your home. This means less mess, no trip hazards, and no risk of damage to your property.
