Why choose tilt and slide doors in Westerham?
Most homeowners choosing tilt and slide doors want the same things: more light, a clear view and a door that is easy to live with.
If a bedroom in your Westerham home opens onto a balcony or garden, the tilt position on tilt and slide doors lets in fresh air at night without leaving the door open.
A kitchen in Westerham that steams up while you cook can be aired by tilting the sash, which is quicker than reaching across the worktop to a window.
- When closed, the sash is drawn back into the frame and presses onto gaskets on all four edges, giving a window-like seal against draughts and driving rain.
- 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.
- Made in both uPVC and aluminium, in white, foiled or powder-coated colours, a tilt and slide door can match the windows around it.

From survey to fitted door in Westerham
Once the opening is measured, nothing is ordered until you sign off the specification. Lead time is typically 2–4 weeks for uPVC or 4–6 weeks for aluminium, from survey sign-off. Our fitters protect floors, remove the old door, install and seal the new one and leave the area clean — usually 1 day for a straight swap in an existing opening for a door like this.
Do you need approval in Westerham?
English Building Regulations treat a new or replacement external door in an existing home as a controlled fitting: it needs a U-value of 1.4 W/m²K or better (or Doorset Energy Rating band C) if more than 60% of it is glazed (Approved Document L), and safety glass in a critical location (Approved Document K). Compliance is arranged through a competent person scheme installer or a Building Control notification, so you get a certificate for your records.

Questions about tilt and slide doors in Westerham
Do you fit tilt and slide doors in Westerham?
Yes. We survey and fit tilt and slide doors in Westerham and across Kent, including nearby Oxted and Sevenoaks. Start with a guide price online or call us, and we will arrange a free survey for a new or replacement door.
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.
Are tilt and slide doors draught-proof?
Tilt and slide doors are among the most draught-resistant sliding designs because the closed sash compresses gaskets on all four edges. Thermal performance depends on frame material and glass. In England, a replacement door in an existing home with more than 60% glazing must reach a U-value of 1.4 W/m²K or better, so the glass is specified to meet it. Wales, Scotland and Northern Ireland have their own requirements.
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.
