Atempted break-in

After an attempted break-in via snapping my euro cylinder lock, ShefLOCK turned up within two hours (I'm based in east Doncaster) and fitted Ultion Locks and secured by design handles. Very thorough with their explanations and careful with installation including cleaning up after themselves.

We have gained a vast amount of security knowledge with over 40 years of police experience. There is so much to talk about so we have put our experience on paper in bite size, easy to read pages.


Laminated double glazing

It is advised that large rear facing doors and large windows are fitted with laminated glass double glazed panels.

This helps keep the glass panels in one piece if they are struck hard to prevent the glass from shattering into small pieces. Although the glass panel will show signs of damage it will prevent anyone from entering your house. We started SheffLOCK as a burglary prevention company because we know that the majority of victims of burglary are receiving either completely wrong Burglary prevention advice, outdated information or simply not receiving any advice at all.
