Questions we will ask at the survey

Which side you lock from

A gate that is only locked from inside suits most homes. If the door is your way out at night, choose a gate that also locks from outside.

Retractable or hinged

Retractable gates need a parking space beside the door for the stack; hinged gates need clear swing space.

Grilles in rented homes

Private landlords in Northern Ireland have fitness and safety duties under the Private Tenancies (Northern Ireland) Order 2006, as amended by the Private Tenancies Act (Northern Ireland) 2022. Grilles over windows a tenant may need for escape should open from inside without a key.

Listed buildings and conservation areas

Listed buildings in Northern Ireland need listed building consent for works affecting their character, with the council deciding and the Department for Communities' Historic Environment Division advising. Conservation areas bring extra scrutiny of external changes.

Door security gates in Derry: questions

Which areas near Derry do you cover?

We can arrange work in Derry and in nearby Strabane (13 miles), Limavady (15 miles) and Coleraine (27 miles). Dates depend on installer availability.

Can a security gate go behind a fire exit door?

Only if it does not obstruct escape while the building is occupied. That normally means it is unlocked and parked open during opening hours and locked only when the premises are empty.

Is a security gate better inside or outside the door?

Inside is usual for back doors because the gate is protected and the door still seals against the weather. Outside works for recessed doorways or where the door opens inwards and would hit the gate.

How do I lock a door gate?

With a key-operated lock box on the closing edge, plus shoot bolts on wider gates. Thumb-turn and quick-release options are available on the inside face.
