Aluminium sliding doors in Dereham: what to know
The right door depends on the opening, the room and the way you use the garden. Here is how aluminium sliding doors tend to work out in practice:
For a south- or west-facing garden in Dereham, solar-control glass in the sliding panels can keep a glazed room more comfortable on summer afternoons.
Where a Dereham property already has aluminium windows, matching the door colour and frame profile keeps the back of the house looking consistent.
- 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.
- 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.
- 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.
How much sun will a door in Dereham get?
Daylight in Dereham runs from about 7 h 37 min in December to 16 h 52 min in June, with the noon sun at roughly 14° and 61° respectively. Use that to choose your glass: standard low-E double glazing for north and east elevations, and consider solar-control or triple glazing for sunny south and west walls.

Survey, manufacture and fitting around Dereham
Once the opening is measured, nothing is ordered until you sign off the specification. Lead time is typically 4–6 weeks 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 two-panel straight swap; 1–2 days for larger doors for a door like this.
Do you need approval in Dereham?
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.
Choosing the specification
- Handles and locks. Slim pull handles or lever handles in matching or contrasting finishes, with an enhanced security locking pack available.
- 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 Dereham
Do you fit aluminium sliding doors in Dereham?
Yes. We survey and fit aluminium sliding doors in Dereham and across Norfolk, including nearby Swaffham and Fakenham. Start with a guide price online or call us, and we will arrange a free survey for a new or replacement door.
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.
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.
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.
