Window Repair in San Tung Chung Hang

Reputable repairers warranty parts and labour — typically 1-2 years on hardware and 5-10 years on new sealed glass units. Ask specifically, because warranty length on the sealed unit is a good proxy for the quality of unit they fit.

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.

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.

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.

A full overhaul strips the sashes out, replaces cords/springs and beads, eases and adjusts, adds draught brush seals, and re-hangs. It transforms operation and draughts while keeping original glass and joinery — the standard treatment for period timber windows before anyone talks replacement.

Single-pane glass is usually same- or next-day: glaziers cut to size on the van or board up and return with the pane. Double-glazed sealed units are made to order — expect a temporary board-up or the cracked unit staying in place for one to two weeks until the replacement unit arrives.

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.
