Window Repair in Côte-Saint-Luc

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.

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.

Large temperature swings pump the glass panes daily, fatiguing edge seals until moisture gets in — so fogged units are routine after 15-25 years. Swapping the unit (not the window) restores performance if frames are sound.
