Window Cleaning Above Glass Basement Extension in South Kensington SW7

Spick & Span Window Cleaning attended a residential property in
South Kensington, SW7, located between Brompton Road
and Thurloe Square, to carry out a specialist
window cleaning service
including windows positioned directly above a glass basement extension.
This project forms part of our ongoing work delivering
window cleaning in South Kensington,
where basement extensions and complex access are a common feature of period homes.
A Historic South Kensington Property
This four-storey, partly stuccoed townhouse dates back to the 1830s and forms part of a terrace
originally developed by builder James Bonnin on land reclaimed in the early 19th century.
The area later became known as the Alexander Estate, one of South Kensington’s most
architecturally significant residential developments.
Ongoing Window Cleaning Maintenance
We provide regular window cleaning maintenance for this property, ensuring consistently clear,
well-presented glazing throughout the year.
A key feature of the home is its modern glass basement extension — a design increasingly found
across South Kensington (SW7), but one that introduces significant access challenges
when cleaning windows above.
Cleaning Windows Above Glass Extensions Safely
Windows positioned above glass roofs and basement extensions require specialist equipment
and experience. Many window cleaners are either unable or unwilling to clean these areas safely.
We are often called to properties where previous cleaners have attempted unsafe methods,
including leaning out of windows, standing on ledges, or even stepping directly onto glass roofs.
These approaches pose serious risks to both the property and those carrying out the work.
Our Safe & Professional Approach
At Spick & Span Window Cleaning, safety is never compromised. Every project begins with
a full assessment of access and risk.
For this property, we used a professional water-fed pole system, allowing us
to safely clean high-level windows without standing on the glass extension or using ladders
in unsafe positions.
This method is ideal for properties across
South Kensington, Chelsea, Belgravia, and Central London,
where modern glass structures are combined with traditional architecture.
Results
The completed clean restored full clarity to all windows, delivering a spotless, streak-free
finish while maintaining complete safety throughout the process.
