Why choose sliding doors for extensions in Crieff?
Before you settle on a door type, it helps to know what sliding doors for extensions do well and what to check before you order.
Self-building in Crieff or elsewhere in Perth and Kinross? 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.
When your Crieff extension is going through Building Control, keep the energy information for the doors to hand, as the inspector may ask for it.
- 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.
- 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.
- 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.
Light and sun in Crieff
Because Crieff sees long summer days (about 17 h 43 min) and short winter ones (about 6 h 52 min), the elevation your door faces makes a real difference. With the midday sun at about 10° in winter, a south-facing door brings light well into the room; a west-facing door catches hot late-afternoon sun in summer.

Questions about sliding doors for extensions in Crieff
Do you fit sliding doors for extensions in Crieff?
Yes. We survey and fit sliding doors for extensions in Crieff and across Perth and Kinross, including nearby Auchterarder and Dunblane. Start with a guide price online or call us, and we will arrange a free survey for a new or replacement door.
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.
How much do sliding doors for an extension cost?

Taller doors, extra panels, special glass and flush thresholds move the price. Your written quote after the check survey fixes it.
