Window Cleaning in Ma On Shan

A regular exterior round on an average house: 20-40 minutes. A first clean or full inside-and-out with frames, sills and tracks: 2-4 hours depending on window count. Window count drives everything — count your panes before calling and quotes get much more accurate.

No — rain itself is fairly clean; the spots you see after rain come from dirt already sitting on the glass. Pure-water-cleaned windows usually stay clear through rain, which is why professional rounds run all year. Most round cleaners offer a re-clean if windows genuinely spot within a day or two of the visit — ask about the policy.

Ordinary cleaning won't remove etched mineral staining from sprinklers, leaking gutters or years of run-off — it needs dedicated hard-water removal products or fine polishing, priced as a restoration add-on per pane. Test one window first: if staining has etched into the glass, no chemical fixes it fully. Fix the water source (gutter, sprinkler aim) or the stains return.

Exterior frames and sills — usually yes with water-fed pole cleaning, since the brush does them anyway. Interior tracks, screens and deep frame scrubbing are typically add-ons. Ask specifically: 'glass only' vs 'glass, frames and sills' is the most common source of disappointment. First cleans should always include frames — dirty frames drip onto clean glass with the first rain.

As part of an hourly helper session, window cleaning folds into the HK$85-$140/hour rate. Dedicated glass-cleaning sessions for a flat run roughly HK$300-$800 depending on glass area. Exterior tower glass is handled by building management, not individual bookings.

Because exterior facade access (gondolas, rope access) is controlled by the building's management company and its licensed contractors — individual flat owners can't hire it per-unit. What you can book is thorough interior-side cleaning plus any panes that open inward. If exterior glass is filthy, raise it with your incorporated owners or management office.
