A practical window lock repair decision starts with the affected item, its condition and the surrounding materials. Repair or fit agreed compatible ordinary mechanical lock or catch hardware and test normal closing and release.
Signs: a handle, latch, hinge, track or screen is visibly worn or damaged or the window is stiff, loose or no longer moves through its normal range. Causes: loose compatible fixings or adjustment points or movement, dirt or damage around the relevant hardware.
A catch may fail because the sash is binding rather than because the lock is broken. For window lock repair, this detail is reviewed before work is accepted so the agreed task stays practical and proportionate. No emergency access, security-screen work, glazing, electronic alarms, key cutting or certification.
