Grille lock replacement and upgrades in Caernarfon: what will it cost?

Most grille lock replacements in Caernarfon cost £150 to £354 including VAT (£125 to £295 plus VAT) per lock fitted. Upgrades such as quick-release or restricted-key cylinders are priced before work goes ahead.

Grille lock replacement means fitting a new cylinder, lock body or complete lock box to an existing security grille. It is the quick fix for lost keys, worn or seized locks and moving into a property with unknown keys, and a chance to upgrade to a stronger or quick-release lock.

What we look at

  • Upgrades to higher-security cylinders
  • Lock work on most grille makes
  • Replacement cylinders and lock bodies
  • Padlock hasp conversions
  • Keyed-alike and master-key suites
  • Quick-release conversions for escape windows

Before the visit

Keyed alike

One key for all grilles is convenient for homes and small shops.

Escape windows

Convert key-only grilles on escape windows to a keyless internal release.

What the rules say in Wales

Wales

Grilles in rented homes

Under the Renting Homes (Wales) Act 2016, landlords must keep dwellings fit for human habitation, which takes fire hazards into account. Grilles over windows a contract-holder may need for escape should open from inside without a key.

Bedroom and escape windows

Wales has its own Approved Documents under the Building Regulations. Approved Document B for Wales sets out escape window provisions for dwellings broadly in line with England's, including minimum opening sizes. We only fit grilles over escape windows with a keyless internal release.

Grille lock replacement and upgrades in Caernarfon: questions

Which areas near Caernarfon do you cover?

Yes. As well as Caernarfon, we can arrange visits in nearby Bangor, Pwllheli and Holyhead, and elsewhere in Gwynedd.

Can you change a lock on a grille you did not fit?

Yes, on most makes, subject to compatible parts.

Can all my grilles use the same key?

Yes, by keying the new cylinders alike.

Is a better cylinder worth it?

On a grille that is otherwise sound, a higher-security cylinder is an inexpensive way to raise resistance to lock attack.
