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.

A faulty window lock is one of the common lock problems in Harrow homes I fix week in, week out.

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.
