Your windows and garage are the entry points burglars test first
Ground-floor windows account for around 30% of break-ins in South London, according to Met Police crime data. Yet most homes have no window locks at all — or locks that haven't been checked in years. Garages face a similar problem: the standard T-bar or barrel lock on a side-hinged garage door can often be opened in under 60 seconds with a basic jemmy.

We fit window locks on casement, sash and uPVC windows — all meeting the key-operated lock requirement most home insurers specify. For garages, we replace worn or defeated cylinders, fit heavy-duty garage door locks, and advise on the right lock for your garage type (Henderson, Cardale, Hormann or Garador).
Every window type has a different locking solution. We cover:
- Casement windows (cockspur & espagnolette)
- Sash windows (sash stops & dual sash locks)
- uPVC windows (multipoint & tilt-turn)
- Timber sash windows (brass sash locks)
- Side-hinged garage doors
- Up-and-over garage doors
- Roller garage doors
- Garden sheds & outbuildings
Shed and outbuilding security is part of this service. A closed shackle padlock on a quality steel hasp — installed correctly — resists bolt-croppers far better than the open shackle padlocks sold in most DIY stores.
All work is carried out by experienced South London locksmiths — no sub-contractors, no cold-call engineers. The person who answers the phone is the person who comes to your property.
Insurance requirement: Most UK home insurers require key-operated locks on all accessible ground-floor windows. Windows without compliant locks may invalidate a break-in claim. We confirm compliance on every job and can provide a written service record if your insurer requests one.

What South London homeowners say
"Came to fit window locks after our insurer flagged that none of our ground-floor windows had key-operated locks. He assessed all six windows, fitted the right lock type on each, and gave me the invoice description I needed for the policy. Couldn't have been more straightforward."

Beckenham, SE26
"My Cardale garage door lock had been stiff for months and finally packed in. Called on a Tuesday morning, they were there by 2pm with the right barrel ready. Quoted £135 on the phone and that's exactly what I paid. Highly recommend for anyone with a Henderson or Cardale door."
David W.
West Norwood, SE27
"Had four Victorian sash windows with nothing securing them. He recommended brass sash stops — fitted two on each window, showed me how they work, and told me which ones were original and didn't need replacing. Refreshingly honest. Sorted everything in under an hour."
Patricia B.
Crystal Palace, SE19
