Frequently Asked Questions — Chelmsford
-
What does a lock change cost in Chelmsford?
Anti-snap euro cylinder £89 to £119. BS3621 mortice replacement £129 to £189. uPVC multipoint gearbox swap £149 upwards.
-
Should I upgrade to anti-snap cylinders on a 1930s semi?
Most CM-area semis built later were retrofitted with uPVC doors carrying basic cylinders. Lock snapping is the most common forced-entry method, so a 3-star cylinder is the single best upgrade.
-
Can you change all the locks in one visit?
Yes. Most properties have two or three external doors. Whole-house lock change runs 60 to 90 minutes.
-
I'm a landlord, do you do tenant-changeover rekeys?
Yes, weekly across the Chelmsford area. Quick turnaround, invoiced direct to the agency or landlord, fresh keys cut on site.
-
Do I get spare keys with the new lock?
Two keys come with every new cylinder or mortice as standard. Extra keys £6 each cut on the van.
-
Will the new lock fit without damaging the door?
Standard sizes match existing fittings on 95% of doors. The engineer measures before fitting to avoid surprises.
-
Is the lock guaranteed?
12 months parts and labour. Premium cylinders add 5 to 10 year manufacturer warranties.
