Turning an existing window into French doors

This is a simple but stunning alteration you can do to your property, and can normally be completed in just two days. French or patio doors when used to replace a window will not only allow much more light to enter the room, but also enhance your garden view whilst providing access straight out onto your patio; a pleasant change - especially in the summer.


If you are keeping the width of the aperture the same, the existing window can often be removed beneath the lintel above and your new doors can simply be installed underneath. We can confirm that this is possible with a simple survey and if so we then just need to remove the wall below.


If we use a disc cutter outside then we will do the cutting into the outside skin before the window is taken out and will cover up inside the room, and use a chain drilling technique to keep dust to a minimum.

Turning a window into a French door is a popular home improvement that can enhance the accessibility, functionality, and aesthetic appeal of your house. Here are the top questions about this type of alteration.


Is planning permission required to convert a window into a French door?


Generally speaking, turning a window into a French door does not require planning permission. However, it's essential to check with your local planning authority, especially if you live in a listed building, conservation area, or have specific restrictions.


What structural considerations are there?


The main structural consideration is ensuring the wall can support the new opening without compromising the building's integrity. This typically involves installing a lintel above the door for support. A structural engineer or qualified contractor can assess and advise on the necessary precautions.


What are the benefits of converting a window to a French door?


Increased natural light, improved access to outdoor spaces, enhanced ventilation, and the visual appeal of French doors can all contribute to the value and enjoyment of your home.


Will it affect the energy efficiency of my home?


The impact on energy efficiency depends on the type of French doors installed. Choosing high-quality, energy-efficient French doors with double-glazing or other insulating features can help minimise any negative effects on your home's thermal performance.
