Frequently Asked

Your Questions — Answered

Everything we get asked before we arrive.

Do you film every job?

We only film with the customer's permission. We always ask before recording.

Will my video be made public?

Only if you're happy for it to be. We can blur house numbers, skip close-ups of keys, and crop any detail you're not comfortable with. We can also keep a job completely private if you prefer.

Do you cover my area of South London?

Yes — Croydon, Sutton, Wallington, Coulsdon, Purley, Thornton Heath, Norbury, Sanderstead, Kenley, and the surrounding postcodes. See our full Areas We Cover page for every postcode we serve.

Is non-destructive entry always possible?

In most cases, yes — especially with standard Yale night latches and euro cylinder locks. On high-security or anti-pick cylinders we may drill the cylinder only (never the door), and replace the cylinder on the spot so you leave locked up.
