Options to consider in Four Oaks

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 Four Oaks: common questions

How long does fitting take?

Fitting doors into a ready opening usually takes one to two days. If we're widening the opening, allow another two to four days for propping, cutting, fitting the beam, inspection and making good. Manufacture usually takes four to eight weeks after the design is signed off, depending on the material and colour.

Which postcodes in Four Oaks do you work in?

We cover B74, B75 and the streets around them. If you're on the edge of Four Oaks, neighbouring Sutton Coldfield and Streetly are covered too.

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.

Will I need permission from the council in Four Oaks?

You won't usually need planning permission, but the work must meet Building Regulations. Building control in Four Oaks is provided by Birmingham City Council or a registered building control approver, and some work is self-certified by registered installers.
