Frequently Asked Questions — Durham

  • How much is a lock change in Durham?

    A standard cylinder swap is £89 to £129. A full BS3621 mortice replacement is £139 to £189, including the lock and labour.

  • How long does it take?

    A like-for-like cylinder swap takes 20 to 30 minutes. A new mortice with hole adjustment can be an hour.

  • Should I change locks after losing keys?

    If keys are gone rather than mislaid, swapping the cylinder is the safer call. The lock body stays, only the cylinder is renewed.

  • What lock fits a Durham Victorian stone terrace?

    Most heritage properties take a 5-lever BS3621 mortice in the lower position with a Yale-style nightlatch above. Both stocked on the van.

  • Do you fit anti-snap cylinders for uPVC?

    Yes. TS007 3-star or SS312 Diamond cylinders are the standard upgrade and what most insurers expect.

  • Can new locks match my existing keys?

    Two or more new locks can be keyed alike at fitting. Matching to an existing third-party key isn't usually possible.

  • Is there a guarantee?

    12 months on workmanship as standard. Manufacturer warranties on cylinders run from 1 to 10 years.
