Is an aluminium sliding door a good fit for your home in Dulwich?
Most homeowners choosing aluminium sliding doors want the same things: more light, a clear view and a door that is easy to live with.
If your Dulwich home has a rear extension or kitchen-diner, aluminium sliding doors let you place a table close to the glass, because no panel swings into the room.
Before aluminium sliding doors are ordered for a Dulwich home, the survey should check the opening width, floor levels and existing lintel, so the quote reflects the real job.
- Because the panels slide rather than swing, nothing opens into the room or across the patio, leaving space for a dining table, sofa or planters right up to the glass.
- Brush and gasket weather seals along every meeting edge, together with drainage slots in the outer track, carry rainwater away instead of letting it collect against the panels.
- Panels run on adjustable tandem rollers along a hard-wearing track, so even a heavy double or triple glazed panel can be opened smoothly with one hand.
Sunlight, glass and orientation in Dulwich
In Dulwich the shortest day has roughly 7 h 50 min of daylight and the longest about 16 h 38 min. The noon sun sits near 15° above the horizon in winter and 62° in summer — so glass that faces south collects useful warmth from October to March, while a west-facing door may need solar control to stop it overheating in July.
Aluminium sliding doors prices in Dulwich
Guide prices are the same across Greater London: the fitted price depends on the size, system and specification, not your postcode. These figures are for a standard 2.1 m high door, fitted, including VAT and removal of an old door of similar size.

|---|---|---|
| 1.5 m | 2 panels | £3,295–£4,095 |

What happens when you order aluminium sliding doors in Dulwich?
Surveys in the SE21 district are booked at a time that suits you. After you approve the quote, manufacture is typically 4–6 weeks from survey sign-off; on fitting day the old door comes out, the new frame is set level and sealed, and the panels are adjusted so they glide properly. Fitting usually takes 1 day for a two-panel straight swap; 1–2 days for larger doors.
Do you need approval in Dulwich?
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.
Choosing the specification
- Threshold. A standard or low threshold, or a flush finish with a drainage channel outside where floor levels allow.
- Panel configuration. Two, three or four panels, with the sliding panel on the left, right or both sides to suit how you use the room.
- Colours. Standard shades such as anthracite grey, black and white, or a special RAL colour for an extra charge.
Questions about aluminium sliding doors in Dulwich
How soon can you survey in Dulwich?
Surveys in the SE21 district are booked at a time that suits you, and we offer survey dates when we reply to your enquiry. After you approve the written quote, manufacture is typically 4–6 weeks from survey sign-off.
How do you look after aluminium sliding doors?
Aluminium sliding doors need little care: wash the frames with mild soapy water a few times a year, vacuum grit out of the bottom track and keep the drainage slots clear. A light silicone spray on the locking points once a year keeps them smooth, and rollers can be adjusted if a panel starts to drag. Manufacturer guarantees on frames, hardware and sealed units are passed to you, and our workmanship guarantee is set out in writing in your quote.
How much do aluminium sliding doors cost?
Aluminium sliding doors start from a guide price of £3,295 for a 1.5 m two-panel door, fitted, inc VAT, at standard 2.1 m height. A 2.4 m door is a guide £4,295–£5,295, and a 4.8 m four-panel door is around £6,995. Glass, colour and threshold choices move the price within the range, and the final figure is fixed in a written quote after survey.
Should I choose aluminium sliding doors or bifolds?
Choose aluminium sliding doors if you want the most glass and fewest frames when the door is closed, and bifolds if you want almost the whole width open in summer. A slider keeps wide panels with slim meeting stiles but only opens part of the width; a bifold folds away but shows a frame every metre or so. Our sliding doors vs bifold doors guide compares them in detail.
