Window Lock Repair & Replacement in Harrow
Window Lock Repair & Replacement in Harrow
A window that won’t lock, a handle that spins or snaps, a stiff mechanism you have to fight – window locks fail quietly until the day they don’t. I do window lock repair and replacement across Harrow and the surrounding areas, and most are a mechanism or handle swap, not a whole new window. Labour from £89, no call-out fee.
Window lock repair: common faults I fix
- Stiff or broken window handles
- Failed espag (the long locking strip down the frame)
- Gearboxes that won’t throw the locking points
- Misaligned sashes that won’t seal
- Seized or worn locks on uPVC, aluminium and timber windows
- Missing or broken keys for locking handles

Why it matters for your security
Ground-floor and accessible windows are a favourite entry point. A window that doesn’t lock properly is an open invitation – worth fixing before it’s exploited. While I’m there I can flag any that need a proper locking upgrade (see additional security).
Every window type
I work on uPVC, aluminium and timber windows – casement and sash. Whether it’s a worn handle, a failed multipoint strip or a lock that’s seized solid, I’ll repair it where I can and replace only what actually needs replacing.
