Bi-fold and patio doors in Gornal

Planning your bi-fold or patio doors in Gornal

Work like this in Gornal rarely needs planning permission, but parts of the job must meet Building Regulations — certified electrical work, ventilation or energy-efficiency standards, for example. Your quote shows how each part is signed off. If planning does come into it, say for a listed building, Dudley Council is the authority.

Glass in a door must be safety glass up to 1,500 mm above the floor.
A flush threshold needs the outside ground set lower, with drainage in front of the door.
With a traffic door on a bi-fold set, you don't have to open every panel to step outside.

Which option fits your home?

Sliding patio doors

Two or more large panels slide past each other on a track, so nothing swings into the room or onto the patio. Sliders give the biggest uninterrupted panes and the narrowest frames, which makes them a good choice where the view matters more than opening the whole wall. Aluminium sliders also suit wide openings.

Widening an opening

Turning a window into doors, or making an opening wider, means cutting the wall and fitting a new lintel or steel beam sized by a structural engineer. Building control must approve the structural work. We organise the calculations, temporary supports, steel and making good, and show these costs on their own lines in your quote.

Bi-fold and patio doors in Gornal: common questions

What guarantee comes with the doors?

The frames, glass, rollers and locks are covered by the manufacturer's guarantee, and the terms for your doors are set out in your quote. Ask how sealed units, running gear and powder coating are covered, as these vary between systems. Keep the guarantee with your certificate and any structural sign-off from building control.
