Patio & French door replacement quotes

Doors that open to the garden take a lot of use and a lot of weather, so a tired patio or French door is often the first thing homeowners want to replace. Because they share frames, glass and colour with your windows, it makes sense to quote them together — a matched set looks better and is usually more efficient to survey and fit than booking the doors separately.

Patio doors versus French doors

Sliding patio doors glide sideways on a track and are ideal where there is no room for a door to swing — they give a wide, uninterrupted view with large glazed panels. French doors are a pair of hinged doors that open outwards or inwards, a classic look for period and traditional homes that suits narrower openings. Bi-fold doors, which concertina back to open a whole wall, are a third option and sit at the top of the range. Each has a different mechanism, glass area and price point.

Whatever the style, a good quote should list the door configuration, the glass specification (toughened safety glass is standard in doors and low-level glazing), the locking and threshold type, and whether a low or level threshold is included for step-free access.

Measuring doors accurately

Door openings must be measured precisely for width, height and squareness, and the threshold checked against the internal floor level. A surveyor also considers how the door swings or slides so it clears furniture, radiators and the patio outside. The same principles apply as for windows — see our guide on how replacement windows are measured. If you are matching doors to existing frames, it helps to compare window styles to replace like-for-like so colours and profiles line up.

Quoting doors with your windows

If you are already replacing windows, adding the doors to the same quote usually shares the survey and fitting costs and gives a consistent finish. Read our guide on full-house window replacement if you are planning a wider project, or the replacement window quote checklist to make sure every quote covers the same scope.
