Why choose sliding doors for extensions in Kelso?
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:
When your Kelso extension is going through Building Control, keep the energy information for the doors to hand, as the inspector may ask for it.
If your Kelso builder is about to pour the screed, confirm the finished floor level for the threshold first, because it is very hard to change afterwards.
- 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.
- Telling the engineer the door type and span early lets them design the beam above it to limit deflection, protecting the smooth running of large sliding panels.
- A check survey once the opening is built means the door is made to the real dimensions, accounting for any small variation in the brickwork or blockwork.
Sunlight, glass and orientation in Kelso
In Kelso the shortest day has roughly 7 h 02 min of daylight and the longest about 17 h 31 min. The noon sun sits near 11° above the horizon in winter and 58° 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.

What happens when you order sliding doors for extensions in Kelso?
Surveys in the TD5 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.
Rules for sliding doors for extensions in Scotland
In Scotland, an extension needs a building warrant before work starts, and the doors are covered by it; the design must meet the Scottish building standards for energy and safety glazing.
Finishes and extras 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.

Questions about sliding doors for extensions in Kelso
Is the price different in Kelso?
No. Guide prices for sliding doors for extensions are the same across mainland Britain, including Kelso. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your written quote after survey.
Why does the steel beam matter for sliding doors?
The steel beam above an extension's sliding door matters because every beam bends a little under load, and a large sliding door needs a straight, level head to run freely. If the engineer knows a wide slider will sit under the beam, they can design for low deflection. Too much movement can make panels stiff or bind.
When should I order sliding doors for an extension?
Order sliding doors for an extension as soon as the opening is built and a check survey can be done, and agree the target fitting date with your builder in advance. Slimline doors typically take 6–8 weeks to make after sign-off. Getting a quote from drawings early means the specification is settled and only the final measurements are needed.
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.
