What does it cost to replace a sliding door?

A uPVC sliding door with HR++ glazing costs €1,800–3,500 in 2026, including installation, for a standard width of 2.4–3.0 m. An aluminium sliding door costs €2,500–5,500. With triple glazing (HR+++) costs are 20–35% higher. Custom sizes and wider openings significantly increase the price.

Which is better: uPVC or aluminium sliding doors?

uPVC sliding doors are 30–40% cheaper and thermally comparable to aluminium with thermal breaks. Aluminium has a slimmer profile, more colour options (RAL colours) and a longer lifespan (50+ years). For a modern interior design, aluminium is more popular; for value for money, uPVC is the smartest choice.

How long does it take to install a sliding door?

Installing a sliding door takes on average 1 working day (6–8 hours) for a standard like-for-like replacement. If brickwork needs to be modified or the opening enlarged, it takes 2–4 days including finishing work.

Do I need a permit for a sliding door?

When replacing an existing sliding door in the same location with comparable material, you generally do not need a planning permit. If you are breaking through a facade to create a new opening, a permit is almost always required. Check with your local municipality.

What is the difference between a sliding door and a bi-fold door?

A sliding door consists of 2–4 panels that slide along a track; at most half the width can be opened. A bi-fold door (concertina door) can fold open completely so the entire facade opening is free. Bi-fold doors are more expensive (€3,000–10,000+) but provide a fully open feel.
