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: the window does not close, catch or sit evenly as it did before or the window is stiff, loose or no longer moves through its normal range. Causes: normal wear in accessible moving hardware or loose compatible fixings or adjustment points.
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.
The final check is ordinary opening, closing and locking, not a security guarantee. 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.
Use the lock gently and report binding, damaged frames or security concerns rather than forcing the sash. Limits: Ordinary mechanical window lock and catch work only. No emergency access, security screens, glazing, electronic alarms or certification.
