Patio door removal is important for renovation projects. Once the new lift and slide, tilt and slide, smart slide or bifold door has been delivered, the old patio door should be removed. Thanks to our guide this is made simple.

Split into two main sections, we explain how to remove the door from its frame, followed by how to remove the frame itself.

As each type of patio door differs in terms of how it should be removed from the frame, there are sub-sections explaining each case.

Materials

  • Tape measure, screwdriver, & ladder
  • Plastic foil surface protection
  • Sabre saw & chase cutter
  • Crow bar & hammer
  • Protective gloves & glasses

Preparatory steps

Before removing a current patio door, it is important to measure it first.

Please refer to our guide "how to measure patio doors" for the process.

The new door should also have been delivered and ready to install.

Additionally, we recommend covering the area surrounding the door with plastic foil to collect dirt and protect surfaces.

The necessary tools should also be collected ready to use and a team of around 4 people will be needed to safely install a larger door.

1. Removing the patio door from its frame

How the patio door should be removed from its frame differs for each type so please refer to the relevant section

Removing a lift and slide door from the frame

Taking out the mobile sash

How an existing lift and slide patio door’s mobile sash should be removed differs depending on whether it is made from aluminium or not. The process is also best carried out by a professional.

Key steps

  • Remove the upper door stopper
  • (Loosen the top rail profile)
  • Remove the mobile door panel

To remove the mobile sash:

  1. With the door closed, remove the anti-lift door stopper (e) (image 1)
  2. Remove the screws from the rail above the fixed part
  3. Fully open the door then remove the screws from the rail above the mobile sash
  4. The rail (b) should now drop down into this mobile sash (a) (image 2)
  5. Tilt the mobile sash (containing this rail) out of the frame (image 3)

To remove the mobile sash:

  1. Slide the door to a central position
  2. Remove the upper anti-lift door stopper (e) (image 1)
  3. Lift the door panel and remove it from the bottom (image 4)

Disassembling the fixed panel (all lift and slide doors)

After following the material-specific procedure above to remove the lift and slide patio door's mobile sash from the frame, the fixed panel should be removed. This can be done in the same way for all lift and slide patio doors – the panel's glass should be taken out, then the fixtures unscrewed, and the panel removed.

Removing a tilt and slide door from the frame

To remove an existing tilt and slide patio door, the following steps should be followed, ideally by a professional:

Key steps

  • Slide the door open
  • Disconnect the upper scissors
  • Remove the door sash

  1. Slide the door open
  2. Release the top scissors connecting the door to the frame (image 1)
  3. Lift the sash from the wheels and remove it (image 2)
  4. Remove the glass from the fixed part

Taking a bifold door out of its frame

Bifold doors feature a main panel connected to other door sashes. To remove them these steps should be followed, ideally by a professional:

Key steps

  • Remove the main panel
  • Remove the other panels

  • Open the main door panel
  • Loosen the main door panel’s hinges with a screwdriver
  • Remove this main door panel
  • Repeat these steps for each consecutive door panel in turn

2. Removing the patio door frame

For all types of patio doors, whether bifold, lift and slide, or tilt and slide, once the door has been removed from the frame, the frame itself can be cut and removed in the same way:

Key steps

  • Cut the soft connections between the frame and wall
  • Break the harder fixtures
  • Remove the frame

Please note that removing door frames takes some patience and strength:

  • Using a cutter, cut the sealing and insulation material between the frame and the wall (a & b)
  • With the sabre saw, cut further hard fixtures, such as brackets (c)
  • Remove the frame (d) using a crowbar, cutting at 45° angles can assist here
