Window & facade cleaning in Hong Kong
Window cleaning for a Hong Kong flat usually costs from about HK$400 for a small apartment to HK$1,600 for a three-room flat, according to sellers' websites in November 2026. Work on high floors and building facades needs a separate quote, so send a request on BlaBlaPrice with the floor height and the number of windows.

Permits for drone and high-rise work
Facade cleaning with a small drone needs permission from the Civil Aviation Department. Its AC-015 guidance applies to operators who want to fly a small unmanned aircraft of up to 25 kg for facade cleaning or similar work. A government innovation project describes drone-powered cleaning for high-rise buildings, so such work is not limited to flats. Ask any company that offers drone work to show its permission before you book.
Domestic helpers and window safety
If a domestic helper cleans windows, Hong Kong labour rules apply. Employment contracts signed on or after 1 January 2017 include a mandatory window-cleaning clause, and employers must make sure windows have grilles that are locked when the helper is asked to clean from outside. Guidance for helpers points to ground-level windows or windows beside a safe balcony or common corridor. For higher windows, book a professional team and say so in the request.
Season and weather
Summer runs from June to August and winter from December to February, so November is a calm month between the two. Outdoor work on high floors depends on the weather, so give two or three possible dates in November or early December. For a flat, the number of windows and the amount of staining matter more than the season, because a stained balcony takes longer to clean.
What to put in the request
Give the number of windows or the area in m², say whether one or both sides need cleaning, and state the floor and the building type, since the height of the windows changes how the job is quoted. Mention stains, the district (Central, Kowloon, Sha Tin, Tsuen Wan or Tuen Mun) and your budget in HK$. If you also need curtains cleaned, list them separately, because curtain cleaning is quoted per item.
Send your request in a chat with a photo of the windows if you can. Sellers registered on BlaBlaPrice reply with their own offer: price, date and what is included. Your contact details stay hidden until you choose whom to contact. If you already know a cleaner, you can also send them the request link. For regular cleaning of the whole flat, see home and house cleaning, or start at the request field on the home page.
