Frequently Asked Questions — Darlington
-
How much is a lock change in Darlington?
A standard cylinder swap is £89 to £129. A full BS3621 mortice replacement runs £139 to £189, including the lock and labour.
-
How long does the work take?
A like-for-like cylinder takes 20 to 30 minutes. A new mortice with hole adjustment can run an hour.
-
Should I change the locks after losing keys?
If keys are gone rather than just mislaid, swapping the cylinder is the safer call. Same lock body, new key set, lower cost.
-
What's the right lock for an older Darlington terrace?
Most Victorian properties take a 5-lever BS3621 mortice in the lower position and 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 for current policies.
-
Can new locks match my existing keys?
Two or more new locks can be keyed alike at the time of 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 depending on brand.
