Frequently Asked Door & Window Security Questions (FAQs)

What is an anti-snap lock, and do I need one?

Anti-snap locks are designed to prevent a common break-in technique where burglars snap the cylinder to gain access. We recommend them for all external doors.

Are thumb-turn locks safe?

Yes — they’re secure from the outside and easy to open from the inside without a key, making them ideal for fire escape compliance in rental properties or HMOs.

Will adding sash jammers make a difference?

Absolutely. Sash jammers add a simple but powerful extra lock to doors and windows, making it much harder to force entry.

Can you upgrade my locks without changing the whole door?

Yes — we can replace and upgrade lock barrels and internal locking systems without replacing the entire door.

How long does installation take?

Most upgrades can be fitted in under an hour per door or window. We work quickly and leave no mess behind.

Do you offer landlord or HMO security packages?

Yes — we can assess the property and fit appropriate locks and security measures to meet safety standards and protect your tenants.
