Sliding doors for extensions and garden rooms in Stourbridge: what to know
The right door depends on the opening, the room and the way you use the garden. Here is how sliding doors for extensions tend to work out in practice:
Self-building in Stourbridge or elsewhere in the West Midlands? Ask for the sliding doors to be quoted as part of a wider glazing package so the frames, colours and glass match across the house.
Where an extension in Stourbridge faces south or west, ask about solar-control glass, because a wall of glass in a single-storey room can overheat in summer.
- Being involved at drawing stage means the opening is formed to suit the door, rather than the door being compromised to suit an opening built a few centimetres out.
- Slimline aluminium systems with interlocks typically around 20–25 mm maximise the glass in a new rear wall, keeping the view as open as possible.
- Agreeing a fitting date with your builder lets the extension be made weathertight on programme, so plastering and flooring can follow without waiting on the doors.
How much sun will a door in Stourbridge get?
The midday sun over Stourbridge ranges from about 14° at the winter solstice to about 61° at midsummer. Low-angle winter light reaches further into a room through a tall door, which is one reason taller panels are worth considering; on south or west walls, pair them with solar-control glass.
What should you budget for sliding doors for extensions in Stourbridge?
Guide prices are the same across the West Midlands. They cover the door supplied and fitted into a prepared opening, including VAT, with options itemised in your quote.
| Overall width | Typical panels | Guide price (fitted, inc VAT) |
|---|---|---|
| 1.8 m | 2 panels | £5,095–£6,195 |
| 3.6 m | 2 panels | £7,795–£9,495 |
| 4.8 m | 3 panels | £9,595–£11,695 |

What happens when you order sliding doors for extensions in Stourbridge?
Nothing is ordered until you sign off the surveyed specification. The door is made from the finished opening sizes (typically 6–8 weeks for slimline systems after check survey sign-off), and fitting usually takes 1–2 days, scheduled to the build programme. If you are in Brierley Hill or Kingswinford, the same process and prices apply.
Rules for sliding doors for extensions in England
Doors in an English extension go through the extension's Building Regulations approval. Under Approved Document L, the total area of windows, roof windows and doors is normally capped at 25% of the extension's floor area plus any openings the extension removes, unless your designer shows compensating improvements; the glass must be safety glazing under Approved Document K.
Finishes and extras for sliding doors for extensions
- Corner opening. Sliding panels meeting at a corner with no post, for extensions open on two sides.
- Triple glazing. For low-energy extensions or north-facing walls, subject to panel size limits.
- Three or four panels. More panels for wider extension openings, with one or more sliding.
Questions about sliding doors for extensions in Stourbridge
Is the price different in Stourbridge?
No. Guide prices for sliding doors for extensions are the same across mainland Britain, including Stourbridge. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your written quote after survey.
How do I get a level threshold in an extension?
A level or flush threshold in an extension needs the finished floor level inside to be set relative to the door sill and the outside paving before the screed goes down. Outside, a drainage channel is needed across the threshold so rain cannot run in. Our thresholds guide explains the options.
Can you work with my builder and architect?
Yes, working with your builder, architect and structural engineer is the normal way we approach extension doors. We can provide technical details, opening sizes, threshold requirements and fixing information, and attend site for the check survey. Your builder forms the opening and prepares the floor, and our installers fit the doors to the agreed programme.
Can you measure from drawings rather than the built opening?
We can quote from drawings, but we manufacture from a check survey of the built opening, because real openings often differ slightly from the plans. Making a large made-to-measure door from drawings alone risks it not fitting. If a programme makes that unavoidable, any arrangement and who carries the risk would be agreed in writing first.
