Are sliding doors for extensions right for your Dunblane home?
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:
If your Dunblane builder is about to pour the screed, confirm the finished floor level for the threshold first, because it is very hard to change afterwards.
Self-building in Dunblane or elsewhere in Stirling, Falkirk and Clackmannanshire? 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.
- Setting the finished floor level before the screed goes down allows a low threshold, typically 15–25 mm, or a flush one with a drainage channel outside.
- 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.
- 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.
Light and sun in Dunblane
In Dunblane the shortest day has roughly 6 h 54 min of daylight and the longest about 17 h 40 min. The noon sun sits near 10° above the horizon in winter and 57° 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.

From survey to fitted door in Dunblane
Surveys in the FK15 district are booked at a time that suits you. Once the opening is ready and measured, manufacture is typically 6–8 weeks for slimline systems after check survey sign-off; on fitting day the frame is set level and sealed, and the panels are adjusted so they glide properly. Fitting usually takes 1–2 days, scheduled to the build programme.
Do you need approval in Dunblane?
A Scottish extension is warrant work: the council approves the design, including its doors and glazing, against the Scottish building standards before building starts.
Which options matter for sliding doors for extensions?
- Two-panel slimline. One sliding and one fixed panel, suiting openings up to around 3.6 m depending on the system.
- Flush threshold. A level floor from inside to out, with a drainage channel set into the patio.
- Three or four panels. More panels for wider extension openings, with one or more sliding.
Questions about sliding doors for extensions in Dunblane
Do you fit sliding doors for extensions in Dunblane?
Yes. We survey and fit sliding doors for extensions in Dunblane and across Stirling, Falkirk and Clackmannanshire, including nearby Bridge of Allan and Stirling. Start with a guide price online or call us, and we will arrange a free survey for a new or replacement door.
What structural opening size should my builder leave for sliding doors?
Your builder should leave the structural opening size we give in writing for your chosen door, which is the frame size plus a small fitting tolerance on each side and at the head. The exact figure depends on the system and the threshold detail. We confirm it from your drawings early, then check the built opening before the door is made.
How much do sliding doors for an extension cost?
Slimline sliding doors for an extension have a guide price of £7,795–£9,495 for a 3.6 m opening and £9,595–£11,695 for a 4.8 m opening, fitted, inc VAT at standard 2.1 m height. Taller doors, extra panels, special glass and flush thresholds move the price. Your written quote after the check survey fixes it.
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.
