Tilt and slide patio doors across County Down
A few practical points decide whether tilt and slide doors suit a particular room and opening:
A kitchen in County Down that steams up while you cook can be aired by tilting the sash, which is quicker than reaching across the worktop to a window.
Is the opening in your County Down home wider than about 3 m? If so, tilt and slide hardware will not carry a sash that size, and a lift and slide door is worth comparing.
- The tilt position opens a narrow gap at the top of the sash while the hardware holds it in place, so a room can be aired without leaving a door open.
- Tilting the sash lets steam and cooking smells out of a kitchen-diner in seconds, without the security worry of a door left wide open.
- A tilt and slide door fits the same kind of opening as an ordinary patio door, so a draughty older slider can often be swapped without building work.

Questions about tilt and slide doors in County Down
Do I need building approval for tilt and slide doors in County Down?
In Northern Ireland the Building Regulations (Northern Ireland) apply through district council building control; work there is by arrangement. We confirm the right route for your property at survey, so the paperwork is in place before fitting.
How do I maintain a tilt and slide door?
Maintaining a tilt and slide door means keeping the bottom track and drainage clear, wiping the gaskets with a damp cloth and lightly oiling the moving hardware points once a year. If the sash starts to catch or the handle feels stiff, the hinges and keeps can be adjusted rather than replaced. Gaskets that have flattened after many years can be renewed on their own, restoring the seal without a new sash.
How much does a tilt and slide patio door cost?
Tilt and slide patio doors start from a guide price of £1,995 for a 1.5 m two-panel door, fitted, inc VAT, at standard 2.1 m height. A 2.1 m door is a guide £2,395–£2,895, and a 3 m door is around £2,995. Aluminium frames, colour and triple glazing move the figure up, and the final price is fixed in a written quote after survey.
How wide can a tilt and slide door be?
A tilt and slide door in our range is typically about 1.5 m to 3 m wide overall, with one opening sash and one fixed panel. The sash size is set by the hardware's weight limit, which is lower than for inline or lift and slide systems. If you need a wider opening, a standard aluminium slider or a lift and slide door is the usual alternative.
