Frequently Asked Questions — Hemel Hempstead
-
When should I change the locks?
After moving in, after a break-in attempt, or any time keys are unaccounted for. Many of Hemel's new-town builds still have the original cylinders from when they were built and are overdue for replacement.
-
How much does it cost?
£89 to £189 fitted depending on type. Anti-snap cylinders sit at the lower end, BS3621 mortice deadlocks at the upper end.
-
Should I upgrade to higher-security cylinders?
Worth considering on uPVC. Brisant Ultion and ABS Avocet add anti-snap, anti-bump and anti-pick protection, particularly relevant in areas with older Mila or Avocet gear.
-
Will my home insurance stay valid?
Yes. We fit BS3621 on wooden doors and Sold Secure SS312 Diamond on uPVC as standard, both insurer-approved.
-
Can all doors share one key?
Yes, key-alike cylinders fitted at the same time. Common request for new-town houses originally supplied with three different keys.
-
How long does the appointment take?
30 minutes for a cylinder swap, around an hour for a full mortice. One visit, parts on the van.
-
Spare keys included?
Three keys come with each new cylinder. Extras are around £6 each.
