Why choose aluminium sliding doors in Crowthorne?
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 Crowthorne property already has aluminium windows, matching the door colour and frame profile keeps the back of the house looking consistent.
Before aluminium sliding doors are ordered for a Crowthorne home, the survey should check the opening width, floor levels and existing lintel, so the quote reflects the real job.
- Aluminium is stiff enough to carry wide panels without bowing, which keeps the number of vertical frames low even across openings of four, five or six metres.
- Polyester powder coating is baked onto the aluminium in the factory, giving a hard, even colour that resists fading and chalking and does not need repainting in normal use.
- Multi-point hook locks grip the frame at several points along the closing edge, while anti-lift blocks stop a shut panel being raised off its track from outside.
Light and sun in Crowthorne
Sun angles matter for big glazed doors. Around Crowthorne, midday sun reaches about 62° in summer and drops to about 15° in winter. That low winter sun is free heat through south-facing glass; high summer sun is easier to shade with a roof overhang, and solar-control glass helps where there is none.

How fitting works in Crowthorne
A surveyor visits your Crowthorne 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 Sandhurst (3 km south) and Yateley (4 km south-west).
Do you need approval in Crowthorne?
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.

Questions about aluminium sliding doors in Crowthorne
Is the price different in Crowthorne?
No. Guide prices for aluminium sliding doors are the same across mainland Britain, including Crowthorne. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your written quote after survey.
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.
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.
Do aluminium sliding doors need Building Regulations approval?
In England, replacement sliding doors are controlled fittings, so the work is either carried out by an installer registered with a competent person scheme, who self-certifies and notifies, or notified to Building Control. The glass must be safety glazing to BS EN 12600. Forming or widening an opening is structural work needing its own application and calculations. Wales, Scotland and Northern Ireland have their own rules.
