What is the price of patio and bifold door grilles in Northolt?

As a guide, patio and bifold door grilles in Northolt 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.

What goes into a patio door grille

  • Locks operable from inside
  • Low-profile or recessed floor tracks
  • Optional extra locking points for wide spans
  • White, black, anthracite or RAL
  • Stacks positioned to clear handles and curtains
  • Matched to aluminium, uPVC or timber frames

London's buildings range from Victorian and Edwardian terraces and mansion blocks to post-war estates, with long high streets of ground-floor shops below flats.

This type of grille suits:

  • Balcony doors in flats
  • Orangeries
  • Bifold doors
  • Sliding patio doors

Questions we will ask at the survey

Colour

Anthracite grilles sit quietly against grey aluminium frames.

Where it parks

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

Planning and safety in England

Grilles inside the glass

A grille fitted inside the glass does not normally need planning permission, because it does not materially change how the building looks from outside. If the building is listed, listed building consent may still be needed.

Bedroom and escape windows

Approved Document B (fire safety) expects many habitable rooms in houses, especially first-floor rooms, to have an emergency escape window with an unobstructed opening of at least 0.33 m², at least 450 mm high and 450 mm wide, with the bottom of the opening no more than 1,100 mm above the floor. We only fit grilles over escape windows with a release that opens from inside without a key.

Patio and bifold door grilles in Northolt: questions

Can you survey in Northolt and nearby towns?

Yes. Surveys in Northolt, Greenford, Harrow and elsewhere in Greater London are booked around installer availability.

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.

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.
