Patio and bifold door grilles in Derry: what will it cost?

As a guide, patio and bifold door grilles in Derry cost £1,074 to £2,994 including VAT (£895 to £2,495 plus VAT) per set of doors, supplied and fitted. The exact figure depends on size, type, finish and locking, and is confirmed in writing after the free survey.

A patio door grille is a wide retractable grille fitted inside sliding patio or bifold doors. Closed, it protects a large glazed opening that is often out of sight at the back of the house; open, it folds into slim stacks so the view and access are unaffected.

Choices you can make

  • Works with sliding, lift-and-slide and bifold doors
  • Low-profile or recessed floor tracks
  • Multi-leaf grilles for openings up to several metres
  • Matched to aluminium, uPVC or timber frames
  • White, black, anthracite or RAL
  • Optional extra locking points for wide spans

Fitting in Derry and nearby

Surveys in Derry (BT48) are booked around installer availability, as they are in nearby Strabane (13 miles) and Limavady (15 miles).

Getting the right patio door grille for your building

Usage

If you open the doors every day, ask for a lighter-action grille with smooth runners.

Where it parks

Bifold doors stack their own leaves to one side; the grille stack should not fight them.

What the rules say in Northern Ireland

Northern Ireland

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.

Bedroom and escape windows

Fire safety in new building work in Northern Ireland is covered by the Building Regulations (Northern Ireland) 2012 and Technical Booklet E. Where a room relies on a window for escape, nothing fitted over it should stop it being used. We only fit grilles over escape windows with a keyless internal release.

Patio and bifold door grilles in Derry: questions

Can you survey in Derry and nearby towns?

Yes. Surveys in Derry, Strabane, Limavady and elsewhere in County Londonderry are booked around installer availability.

How long does fitting take?

A typical set of patio doors takes half a day once the grille is made.

Can I walk over the grille track?

Yes. Low-profile tracks are a few millimetres high, and recessed tracks sit flush with the floor.

Can the grille be fitted outside the patio doors?

It can, but inside is usual because the grille is protected and the outside of the house stays the same.
