What is the price of patio and bifold door grilles in Watford?
As a guide, patio and bifold door grilles in Watford 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.

Questions we will ask at the survey
Where it parks
Bifold doors stack their own leaves to one side; the grille stack should not fight them.
Track
A low-profile track keeps the threshold easy to walk over. Recessed tracks need a little floor work.
Planning and safety in England
Listed buildings and conservation areas
Listed buildings need listed building consent for works that affect their character, which can include internal grilles and their fixings. In conservation areas, councils look closely at anything fitted to the outside. We recommend speaking to the council's conservation officer before ordering.
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 Watford: questions
Do you cover Bushey as well as Watford?
Yes. As well as Watford, we can arrange surveys in nearby Bushey, Rickmansworth and Borehamwood, and elsewhere in Hertfordshire.
Will a grille get in the way of my bifold doors?
No. We plan the stack so the bifold leaves and the grille fold to positions that do not clash.
Do patio grilles block the view?
When open, only a slim stack at each side. When closed, the lattice is open enough to see the garden clearly.
How long does fitting take?
A typical set of patio doors takes half a day once the grille is made.
