Bifold doors are glazed panels that fold and stack to one side to open up a wide gap, while sliding doors glide past each other on tracks; both connect a living space to the garden and bring in more daylight.
Addresses across KY16 fall within our coverage for bifold or sliding doors, so if your home is in St Andrews we can arrange a survey on a day that works for you. We inspect the existing building, discuss materials and layout, and then price the agreed specification in writing. Expect a guide range of £2,900–£7,700 including VAT before that visit.

How much do bifold or sliding doors cost in St Andrews?
To help you plan, we show what bifold or sliding doors typically costs in St Andrews instead of holding figures back for a sales call. The range is £2,900–£7,700 with VAT, using rates in Scotland that are about 4% below the national guide. A free survey then fixes your actual price.

| Wide bifold or slimline slider | Openings of 4m or more and slim-frame doors, often with a new steel above. | £6,700–£13,500 |
The main things that change the figure:

- Glazing upgrades such as solar control or triple glazing
- Threshold type, colour choice and built-in blinds

Local housing and bifold or sliding doors
Fife's East Neuk fishing villages are known for pantiled roofs and crow-stepped gables, and St Andrews has historic stone streets. Kirkcaldy and Dunfermline have Victorian sandstone housing and interwar estates, Glenrothes was built as a post-war new town, and former mining towns in central Fife have rows of cottages and post-war council housing.
Pantiled and stone homes need careful roof repairs and lime work. Post-war and new-town houses commonly take re-rendering, window replacement and extensions, while bungalows suit loft conversions.
So when we survey a St Andrews property for bifold or sliding doors, the first step is working out how it was built and what has been changed since.
Planning and building rules in St Andrews
St Andrews is in Scotland, so the planning and building rules set out below are the ones that apply. We confirm the details with the council before we quote.
In Scotland, replacing windows and doors on a house generally needs no planning permission when the style is similar, but listed buildings and conservation areas are closely controlled and often need consent for any change of material or pattern.
A building warrant is not usually needed for like-for-like replacement windows, but the new units must still meet the Scottish building standards, including energy performance and, where relevant, escape from upper floors.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.

Frequently asked questions
Will large glass doors make my room cold?
Large glass doors lose more heat than an insulated wall, but modern double glazing with thermally broken frames performs far better than older patio doors. Solar control glass helps stop south-facing rooms overheating in summer. In extensions, building control looks at the total glazed area, so heat-loss calculations may be needed. We can suggest glass specifications that balance light, warmth and cost.
How long do bifold doors take to make and fit?
Aluminium bifold and sliding doors usually take several weeks to manufacture after the survey, depending on the supplier and colour. Fitting into a ready opening normally takes one to two days, including sealing and finishing trims. If we are widening the opening, allow a few extra days for the structural work and making good before the doors arrive. We give you the expected timeline with your quote.
How much do bifold doors cost?
Bifold doors cost £2,900–£7,700 for a typical 3m opening, supplied and fitted. As a rough guide, allow around £900–£2,000 per metre of width plus the fixed costs of fitting, depending on frame material and glass. uPVC sits at the lower end and slimline aluminium at the top. Widening the opening with a new steel adds to the price. We confirm a fixed figure after measuring.
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
