Installing French Doors: Frequently Asked Questions

Now you know to basics on how to install an interior double door, but every door is different. Here are a few extra tips, tricks and things to look out for during the process.

Who Should Install Internal French Doors?

As you can see, the basic process of installing internal French doors is fairly straightforward. You can tackle the job yourself. However, sometimes it can be worth employing a professional for extra peace of mind. A tradesman should be able to complete the job with ease, provide a great finish and overcome any unforeseen problems.

How Much Does it Cost to Fit Internal French Doors?

As a rough guide, we’d expect a basic installation to cost around £100 – £150.

Please bear in mind that there are a whole host of things that will affect the price. Any complications, additional work like removing old doors and even your location can have an impact. The best thing to do is get a few quotes from comparable tradesmen.

Sidelights & Transoms

If your door opening is large or you’d like to let extra light in, sidelights or transom windows can be used in conjunction with French doors. Sidelights are glass panes that sit on either side of the door and transom sits above.

These items can be bought to match the door and may be sold together. Adding some shouldn’t make much difference to the installation process, just be sure to measure up accurately!

Door Pair Options

Double doors have different pairing options so you’ll need to consider which of these you have before installing. Here are the different types of double door pairs and what to consider as you fit them.

Square Meeting Stiles

The edges of these doors that meet are square, and the two doors are fitted side by side. As you install them you’ll need to make sure you leave a 2-3mm gap between the doors to ensure the doors don’t catch.

Rebated Meeting Stiles

Rebated door pairs have a small section removed on each door where the pair meets. This allows the two doors to interlock as they close, removing the need for a gap and creating a more polished finish.

If your door pair is rebated then you’ll need to take extra care when fitting to accomplish this snug fit. You’ll also need to be aware of the opening direction, and consider which door will be the lead door (i.e. which will open first).

Using a Pair Maker

If your door has square meeting stiles and you would prefer a neater look, there’s always the option to fit a pair maker. This is a timber moulding that can be fixed to one edge to get rid of the gap and create the illusion of a rebated pair with ease.

When installing, you’ll need to consider the opening direction just like you would if installing a rebated pair.

To Sum Up

A set of French doors can transform the appearance of your home and fitting them doesn’t need to be a headache. Measure carefully, take your time and make sure you have someone on hand to help. Your new internal French doors will be up and running in no time!
