Window Cleaning in Wong Tai Sin

Three models: per pane/window (most transparent for one-offs), per visit (standard for regular rounds — a fixed price for your whole house), or hourly (rare for homes, common for commercial). Regular-round pricing is far cheaper per clean than one-offs because maintained glass cleans fast. Always confirm whether the price covers exterior only or inside and out — that single detail explains most quote differences.

Many do, as a priced add-on — conservatory or glass-roof cleaning is slower, needs care about walking loads, and often costs as much as the rest of the house combined. Self-cleaning glass coatings still need occasional professional attention. Ask when booking; not every round cleaner carries the right equipment.

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.

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.
