Key takeaways
- Most window repair jobs in Hong Kong land between HK$400–HK$12,000 — known locally as window repair (mwis / minor works).
- Hong Kong's Mandatory Window Inspection Scheme requires owners of buildings over 10 years old to have windows inspected and repaired via registered contractors when notified. Typhoon exposure makes hinge and fixing corrosion the key safety fault to fix early.
- Prices below are researched national ranges, updated July 2026 — not quotes.

What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in Hong Kong typically run above the national range; smaller towns below it.
How to save

- Be flexible on timing — off-peak slots are often cheaper.
- Bundle related tasks into one visit to spread call-out costs.
- Agree the scope in writing up front to avoid change-order surprises.

Frequently asked questions
Can draughty windows be fixed?
Yes — new compression seals/weatherstripping, hinge adjustment and lock realignment fix most draughts, and sash specialists rout in brush seals on older windows. It is one of the highest-payback repairs: cheaper heating bills and less noise without replacing anything.
Why is my window stiff, dropping, or not closing properly?
Usually worn friction hinges, tired rollers on sliders, or a dropped sash catching the frame. These are standard parts a repairer replaces in under an hour. Ignoring a dropping casement eventually strains the frame and glass, turning a cheap fix into a big one.
Can misted (fogged) double glazing be fixed without replacing the window?
Yes — the sealed glass unit swaps out of the existing frame, restoring clarity and insulation for far less than a new window. 'Demisting' services that drill the unit are cheaper still but results are mixed and insulation isn't restored; most pros recommend a new sealed unit.
Is it worth repairing a window or should I replace it?
Repair wins when the frame is sound: misted glass units, broken hardware, draughts and stiff sashes are all fixable at a fraction of replacement cost. Replace when frames are rotten through, warped, or repairs recur — or when energy performance is the real goal and the windows are single-glazed anyway.
How much does window repair cost?
Most window repairs are call-out jobs: hardware fixes (handles, hinges, locks, rollers) sit at the low end, replacing a failed double-glazed sealed unit sits mid-range, and structural frame or sash overhauls cost the most. Repair typically runs a quarter to half of replacement — get both numbers quoted when a window is marginal.
When must I repair windows under MWIS?
When your building receives an MWIS notice, a Qualified Person inspects and prescribes repairs, which registered contractors then carry out — typically on a 5-year cycle. Fixing loose or corroded windows before typhoon season is prudent regardless of notices.
