Choosing a large sectional door for a home in Portishead

What about oak-framed and timber buildings?

Doors can be fixed to timber frames, but the fixings and any packers have to suit the frame, and green oak moves as it dries. The survey checks the frame and the fixing positions.

Can large doors be insulated and glazed?

Yes. Most large doors use insulated panels, and window rows or vision panels can be added to bring light into a long garage.

Which options are available in Portishead?

  • High-lift tracksUse roof height so the door parks higher.
  • Heavier springsSpring sets sized to the larger door weight.
  • Shaft or rail operatorSpecified to the door size.
  • Vision rowsWindows across one section.

What will a large sectional door cost in Portishead?

Guide price: from £4,495 inc VAT. The figure includes VAT, fitting and taking away a standard old door. Your survey turns it into a fixed price.

Our free survey checks the opening, headroom above it, room either side for the tracks, garage depth and where an operator will be powered from.

Yes, provided the building has the height and structure for the tracks and the door. We measure headroom, side room and depth at survey.

It needs an operator rated for its size and weight, which may be a heavier rail operator or a shaft-mounted unit.
