Top tips
Hiring a window cleaner, without the regret.
Four moves that separate a smooth job from a nightmare.
Water-fed pole or traditional?
Water-fed pole reaches 4 storeys, uses pure water (no streaks). Traditional ladder/squeegee for ground floor and detail work. Most modern cleaners use both.
Don't pay by the window — pay by frequency.
Reputable cleaners charge a fixed price per visit, with set frequency (monthly, 6-weekly). Per-window pricing encourages skipping the trickier ones.
Check public liability cover.
Even pole-cleaning has risks — chipped masonry, broken seals, scratched UPVC. £2m liability is the minimum standard.
Get the frames included.
uPVC frames yellow without periodic cleaning. The window-frame wipe should be included — not a £5 extra per visit.
