What are French Doors?

French doors are made up of a pair of doors that open outwards on a hinge, either into a garden space or between internal rooms. The doors themselves are largely made up of a glass pane that allows plenty of natural light into the home.

French Door Types

Conventionally, French doors are installed at the back of a home leading outside into a garden area but they can also be fitted internally and sliding options are also available.


Installed at the back of a home, exterior French doors swing outwards into a garden space to create a spacious walkthrough from the inside to the outside.


Interior French doors are perfect for separating 2 rooms that you will occasionally want to enjoy as a single large space. They have the same aesthetics as exterior French doors and work in the same way to allow more light to spread around your home.


Typically, French doors open outwards on a hinge but sliding French doors are also available. A pair of doors slide away from each other and cover a panel that sits either side of the doors.

Sliding French doors are different to sliding patio doors as they only tend to have one movable side.

Common French Door Problems

If you’re looking for replacement French doors then the chances are you have a problem with your current ones. Some common French door problems include:

  • Doors not closing properly
  • Latches not working
  • Loose hinges causing the doors to drop
  • Handles getting stuck
  • A gap between the doors

It would be possible to get most of these fixed but if your French doors were installed a number of years ago then replacing them might be the better option.

Replacement French Doors: What are Your Options?

When the time comes to replace your existing French doors, you might want to consider the other door options available to you.

Patio doors

Patio doors, or sliding glass doors, have one fixed side and one moveable side which slides to one side, overlapping the fixed side. Sliding patio doors are a popular choice in the UK and have many benefits:

  • Simple to open
  • Secure
  • Allow natural light and fresh air inside
  • Ideal for keeping the inside cool during the summer

Bifold doors

While patio doors can replace external French doors, bifold doors can be installed internally or externally. Bifold doors are made up of between 2-7 panels that fold into each other when opened, leaving a spacious walk through to the next room or garden. Bifold doors can even be installed around corners to really open up your home, however you’ll no longer be able to open a single door as you can with French doors.

Benefits of bifold doors include:

  • Allow more natural light into the home
  • Create a large amount of space when open
  • Can be installed into larger openings by adding more panels (even around corners)

French doors

If you’re not looking for a different style of door, then it’s possible to replace old or broken French doors with new French doors.

New French doors will still swing open on a hinge – either outwards or inwards – but the newer model will increase security and greatly reduce the need for any repairs.

Patio Door Materials

When replacing French doors one of the important considerations to make is the material you want the new doors to be made from. Patio door materials include:

  • Aluminium
  • Composite
  • uPVC
  • Timber

While timber is often the most desirable because of its charming aesthetics, uPVC is the most popular choice in the UK thanks to it being the cheapest material.

How Much do Replacement French Doors Cost?

The price of replacement French doors vary greatly depending on the type of door being installed, the material and the size. As well as having some new French doors installed, your options also include sliding patio doors and bifold doors.

Replacing french doors with windows might also be an option, however this will lower the number of exits from the property so you may need building consent.

Material Potential Cost
Aluminium £1,050+
Composite £800 – £2,000
Timber £900+
uPVC £725 – £1,4000

Sliding patio doors

If you want to replace French doors with sliding doors, this is something that’s only possible on external installations, leading out to a garden area.

Material Potential Cost
Aluminium £2,000+
uPVC £700 – £1,500

Bifold doors

Bifold doors make a fitting replacement for French doors either internally or externally, with the price varying not only based on material but the number of panels needed too.

Number of Panels Potential Cost
3 £1,200 – £2,300
4 £1,500 – £2,750
5 £2,500 – £5,500

On top of the cost of the doors, you’ll also need to consider the installation costs which will also vary as installers all set their own prices.
