The Choices You Will Make When Ordering French Doors
Most of the questions people have come down to a handful of decisions. Here they are in the order we usually talk them through at your survey.
| Choice | Your options | What we usually advise |
|---|---|---|
| Opening direction | Outwards or inwards | Outwards is the standard and saves floor space inside |
| Main (master) door | Left or right hand | Choose the leaf you will use every day, the other stays locked until needed |
| Glazing | Clear, Georgian bars, decorative glass | See the section on bars below |
| Glass specification | Double or triple glazing, toughened | Triple for cold or noisy elevations, double is enough for most |
| Extra light | Side panels and toplights | Narrow side panels widen an opening without a bigger structural change |
| Threshold | Standard cill or low threshold | A low threshold is better for step free access, ask us about the trade offs |
| Colour and hardware | Colours, woodgrain, handle finishes | Match to your windows so the house looks consistent |

Open Out or Open In?
Almost all French doors open outwards, and that is what we recommend for most homes. There are cases where inwards works better.
- Outward opening saves indoor space, so furniture and curtains can sit close to the doors
- Outward opening suits most gardens, as long as the patio has room for the doors to swing
- Inward opening suits a narrow side return or a path where an outward swing would block the way
- Inward opening versions often cost a little more and need clear space inside, which may affect curtains and furniture
- Tell us how you use the space at your survey and we will recommend the right direction

Georgian Bars or Clear Glass?
This is the choice that changes how the doors look from the street and from the sofa.
- Georgian bars sit inside the sealed glass unit and suit Victorian, Edwardian and traditional homes
- Because the bars are inside the glass, they cannot be removed later, so decide before you order
- Clear glass gives an uninterrupted view of the garden and suits modern homes and extensions
- Decorative or obscured glass can add privacy where a door faces a neighbour or a side path
- Either choice keeps the same security and energy performance

Large Glass Doors Without the Worry
A door that is mostly glass raises two fair questions: is it secure, and will it keep the room warm?
- Toughened glass is fitted for strength, with laminated glass options for extra impact resistance
- Multipoint locking engages at several points around the doors, and the second leaf is secured so both stay shut
- Internal beading holds the glass in from the inside, so it cannot be removed from the outside
- Warm edge spacer bars and gas filled glazing reduce heat loss at the edge of the glass
- Triple glazing adds warmth and sound reduction for cold or noisy elevations
- Compression seals around both leaves reduce draughts at the central join

Three Ways to Fit French Doors
Where your doors go decides the work involved, the time and the cost.
1. Replacing existing French doors or a patio door. The simplest job. We remove the old doors, fit the new frame and make good. This usually takes around a day.
2. Converting a window or old door opening. We fit French doors into an existing opening, which may mean lowering the sill and making good the brickwork. It takes longer than a like for like swap and costs more.
3. Creating a brand new opening. A new opening in a wall needs a structural lintel and usually Building Regulations approval, and should be planned with a builder or structural engineer. Replacing a window with French doors is often allowed without planning permission, but check with your council if your home is listed or in a conservation area.
We tell you which of these applies at your survey, so you know the full scope before you commit.

French Doors Room by Room
- Kitchen diner: toplights and side panels add light to a deep room, and a low threshold keeps the floor level continuous
- Living room: Georgian bars suit a traditional front room, while clear glass suits a modern lounge opening to the garden
- Garden room or conservatory: French doors create a traditional access point and match well with uPVC conservatory frames

Frequently Asked Questions
Ask Us a QuestionWhat is the master door on French doors?
The master door, sometimes called the leading or traffic door, is the leaf you open first and use for everyday access. The second leaf stays locked and opens only when you need the full width. You choose left or right hand when you order, so pick the side that suits how you walk through.
Can uPVC French doors open inwards?
Yes, though outward opening is the standard. Inward opening is useful where an outward swing would block a narrow path or side return, but it needs clear space inside and often costs a little more. We recommend the right direction for your layout at your survey.
Are French doors draughty, and will rain come in?
A properly fitted set is not draughty. Compression seals around both leaves and a well designed threshold keep out draughts and rain. Problems usually come from worn seals or a frame that was not fitted square, which is why installation matters as much as the product.
How do French doors lock?
The main leaf has a multipoint lock that engages at several points down the edge, and the second leaf is secured so that both stay firmly shut. Internal beading and toughened glass add strength to the glazing.
How wide can uPVC French doors be?
Standard sets are commonly about 1.2m, 1.5m or 1.8m wide (4ft, 5ft or 6ft), and side panels can make an opening wider. Ours are made to measure to your opening, so we can match the size you need.
Do I need planning permission or Building Regulations approval for French doors?
Replacing existing doors or a window usually does not need planning permission, though listed buildings and conservation areas are different. Creating a brand new opening in a wall normally needs a structural lintel and Building Regulations approval. A FENSA certified installer certifies replacement doors, and we advise you at survey.
How do I adjust uPVC French doors if they drop or stick?
Most uPVC door hinges can be adjusted with a hex key for height, side to side and how tightly the door presses on the seal. Small adjustments often cure a door that drags on the threshold or will not lock easily. If it does not improve, ask us to check it, as a door that keeps dropping can be a sign of worn hinges or a frame that needs attention.
How much do uPVC French doors cost?
Supply only prices for standard white sets start at about £720 to £760 from trade suppliers, while fully fitted prices typically run roughly £1,100 to £1,800 in UK guides. Size, glazing, colour, side panels and fitting work all affect the price. These are national guide figures, not a Eurothermal quote, so book a free survey for an exact price.
Should I choose French doors, patio doors or bi-fold doors?
Choose French doors for a traditional framed opening that you can use one door at a time. Choose sliding patio doors where you have no room for a door to swing, and bi-fold doors where you want a whole wall to open. See our uPVC Patio, Sliding Patio and Bi-Fold pages for more.
