Windows are often the weak point in home security. While front doors get deadlocks and anti-snap cylinders, plenty of Tooting’s windows still rely on a simple catch, or nothing at all. Upgrading your window locks significantly improves your property’s protection against intruders, and it is one of the most cost-effective security jobs there is.

Window locks for Tooting’s homes

Tooting’s streets mix Victorian and Edwardian terraces with newer uPVC-fitted houses and flats, so we carry lock options for every window style found here:

  • Sash locks for traditional box-sash windows, including dual screws and sash stops that let you lock a window slightly open
  • Casement locks for hinged timber windows, fitted discreetly so period frames keep their looks
  • Sliding window locks for modern sliders and patio-style windows
  • Key-operated handles and mechanism repairs for uPVC windows, including replacement espagnolette gearboxes and handles

Every lock we install complies with British Standards and insurance requirements, giving you real security and, in many cases, ticking the exact box your home insurance policy asks for.

Why upgrade now

If your current window locks are old, damaged or missing altogether, your windows are the easy way in, and burglars know it. Modern window locks provide far better resistance against forced entry, making your home a much less attractive target. As a bonus, a properly closing, properly locking window seals better too, reducing draughts and heat loss.

Ground-floor flats and houses backing onto alleys, railways or gardens benefit most; it is also well worth doing after a break-in or attempted one, alongside our after burglary services.

Assessed honestly, fitted efficiently

Our locksmith looks over your windows, recommends the right lock for each one and agrees the price before any work starts. Most upgrades are completed in a single visit from the van’s stock, tested with you window by window, and covered by our 12-month warranty on parts and workmanship.
