Window Cleaning in Kensington
Clear, streak-free glass for Kensington homes, mansion blocks and businesses, cleaned safely from the ground with the Reach & Wash system.
Kensington’s buildings set a high bar for their windows. Stucco terraces around South Kensington and Holland Park have tall sash windows over several floors, often with balconies, bay fronts and basement lightwells behind railings. Red-brick mansion blocks near Kensington High Street bring long runs of glazing and strict building rules, while mews houses, conservatories and garden rooms add glass that is hard to reach from the street. Our Reach & Wash operatives clean all of it from the ground with purified water and soft brushes on carbon-fibre poles, up to six floors high. There are no ladders against painted stucco and no chemicals near window boxes or gardens, and the glass dries clear without smears.

Areas We Cover
Window cleaning across Kensington, planned around the windows, access and building rules on your street.
Holland Park
W11 · W14Holland Park’s large villas, from Holland Park Avenue to Addison Road, have wide bay windows, glazed porches and rear conservatories facing long gardens. Much of this glass is out of reach from the street. Our poles reach upper sashes and conservatory roofs from the ground, so there are no ladders against painted stucco or on garden lawns.
Window cleaning in Holland ParkCampden Hill
W8On Campden Hill’s steep streets, Victorian villas sit beside mansion blocks off Hornton Street and Campden Hill Road. Gradients make ladder work unsafe, and the mansion blocks have long runs of glazing over many floors. We work from level ground, and we agree access and timings with porters and managing agents in advance.
South Kensington
SW7The white stucco terraces around Queen’s Gate, Onslow Gardens and the garden squares have tall sash windows on four or five floors, with balconies and basement lightwells behind railings. Pure water leaves the glass clear without detergent residue, and it won’t mark painted stucco or the plants in window boxes.
Window cleaning in South KensingtonEarls Court
SW5Earls Court’s tall Victorian houses, around Earls Court Square and Nevern Square, are mostly converted into flats. No single tenant can reach the upper-floor windows. A single Reach & Wash booking can cover the whole building’s front and rear elevations, and costs can be shared between leaseholders.
Window cleaning in Earls CourtEdwardes Square and Abingdon
W8Small Georgian houses around Edwardes Square and Pembroke Square have multi-pane sashes, fanlights and basement windows facing narrow lightwells. Small panes show every streak. We clean them with soft brushes and purified water, with care for older glass and timber frames.
Kensington High Street
W8Shopfronts, restaurants and offices along Kensington High Street pick up traffic grime daily, with flats and mansion blocks above. Loading restrictions limit when vans can stop, so commercial cleans are booked early, before trading, and repeated on a regular schedule.

Window Cleaning Questions
Anything else? Call 020 7099 6964.
How often should my windows be cleaned?
For most Kensington homes, every eight to twelve weeks keeps glass clear. Properties on busy roads such as Kensington High Street or Cromwell Road gather traffic grime faster, so four to six weeks often suits them, and shopfronts are usually cleaned weekly or fortnightly.
Can you clean balconies, conservatory roofs and skylights?
Yes. Our poles reach balcony glass, glazed porches, conservatory roofs and most skylights from the ground or a garden. Where glass can only be reached from a balcony or roof terrace, we’ll arrange access with you before the visit.
Do you clean window frames and sills as well as the glass?
Yes, as standard. The brush cleans frames and sills along with the glass, and the pure-water rinse washes the dirt away. On painted timber sashes, this lifts the grime without chemicals that could dull or damage the paint.
Can you clean the windows of a whole block or converted house?
Yes. We clean mansion blocks and converted houses for managing agents, freeholders and residents’ associations, often on a regular schedule. One booking covers all floors and elevations, and we agree access and timings with the porter or building manager.
Is pure water safe for window boxes, stucco and stonework?
Yes. Purified water contains no detergents, so the run-off won’t harm plants in window boxes, mark painted stucco or stain stone sills and steps. This matters on Kensington’s garden squares and stucco terraces, where frontages are kept in good order.
How do you handle parking on Kensington’s restricted streets?
Most Kensington streets are covered by RBKC parking controls, and many mews and garden squares have no room for a van. Let us know about any visitor permits, off-street spaces or building rules when you book, and we’ll plan the visit around them.
