Are aluminium sliding doors right for your Lewisham home?
Most homeowners choosing aluminium sliding doors want the same things: more light, a clear view and a door that is easy to live with.
Where a Lewisham property already has aluminium windows, matching the door colour and frame profile keeps the back of the house looking consistent.
Thinking about a dark frame for a house in Lewisham? Anthracite grey and black powder coats show off slim aluminium sightlines, and dual colour keeps the inside lighter if you prefer.
- 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.
- A polyamide thermal break inside every profile separates the cold outer metal from the warm inner face, cutting heat loss and reducing the risk of condensation forming on the frame.
- 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.
How much sun will a door in Lewisham get?
In Lewisham 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.

Timescales for aluminium sliding doors in Lewisham
A surveyor visits your Lewisham home to measure the structural opening, check levels and the lintel, and talk through glass and finish. Once you confirm the written specification, the door is made to measure — typically 4–6 weeks from survey sign-off — and fitting usually takes 1 day for a two-panel straight swap; 1–2 days for larger doors. We also cover Blackheath (1 km north-east) and Catford (2 km south).
Do you need approval in Lewisham?
In England, a replacement sliding door is a controlled fitting under the Building Regulations. In an existing home, a door with more than 60% glazing must reach a U-value of 1.4 W/m²K or better (or a Doorset Energy Rating of band C) under Approved Document L, and glass in doors must be safety glazing under Approved Document K. We arrange compliance through a competent person scheme installer or by notifying Building Control, and you receive the certificate.
Which options matter for aluminium sliding doors?
- Glass. Double or triple glazed units in toughened or laminated safety glass, with solar-control or self-cleaning coatings.
- Colours. Standard shades such as anthracite grey, black and white, or a special RAL colour for an extra charge.
- Threshold. A standard or low threshold, or a flush finish with a drainage channel outside where floor levels allow.
Questions about aluminium sliding doors in Lewisham
How soon can you survey in Lewisham?
Surveys in the SE13 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.
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.
Are aluminium sliding doors warm enough for a UK home?
Thermally broken aluminium sliding doors are warm enough for most homes, with typical whole-door U-values around 1.2–1.6 W/m²K double glazed and 0.8–1.1 W/m²K triple glazed, depending on the system. In England, a new or replacement door in an existing home with more than 60% glazing must reach 1.4 W/m²K or better, so the glass is specified to meet that. Wales, Scotland and Northern Ireland have their own rules.
Are aluminium sliding doors secure?
Aluminium sliding doors can be very secure when they combine multi-point hook locks, anti-lift blocks and laminated glass. Systems are available tested to PAS 24, the UK enhanced security standard for doorsets, and an enhanced security locking pack can be added to your quote. Most systems are glazed from the inside, so the glass cannot be unclipped from outside.
