- Measure your door in mm from the outside of the property.
- Measure the brickwork opening in 3 places for both width and height.
- Of the 3 measurements use the smallest and deduct approximately 10mm, that's your order size.
- Always measure in millimetres (mm).
- The height measurements must be from underneath of any existing removable cill (except stone cills or if you're ordering doors without cills).
- If your property is rendered, remove some render and measure to the brickwork edge.
Please note: We are unable to accept responsibility for incorrect measurements.
If you are unsure we recommend that you consult a professional installer/builder.
