Stage 1: the survey
A made-to-measure door starts with an accurate measurement. The surveyor measures the opening and checks the frame, sill and brickwork around it.
They also talk you through styles, colours, glass and handles. This is the time to mention side panels, a top light or a new canopy, because each one changes the job.
Stage 2: making the door
A composite door is built to the size of your opening, so it is not taken off a shelf. This stage is usually the longest part of the wait.
Ask your installer for a fitting date in writing once you order. A firm that makes its own doors can tell you where your door is in the queue.
Stage 3: fitting day
On the day, the installers protect your floor and take out the old door and frame. They fix the new frame into the opening, pack and seal it, then hang the door.
Before they leave, they should set the locks, check the door closes and locks cleanly, and show you how it works. The area should be left tidy.
- Plan to be at home for the whole visit.
- Clear the hallway and the path to the door.
- Move anything fragile away from the door.
- Have a place ready for the old door if you want to keep it, or ask if it will be taken away.
| Stage | Who | What happens |
|---|---|---|
| Survey | Surveyor | Measures the opening, checks the frame and wall, and talks through styles |
| Making | Door maker | Builds the door and frame to the exact size of your opening |
| Fitting | Installers | Removes the old door, fits and seals the new frame, hangs and checks the door |
What can make it take longer
A simple swap of one door in a sound opening is the quickest job. These things add time:
- Side panels or a top light fitted with the door.
- A rotten sill or damaged brickwork that needs work first.
- An odd-sized opening, or a change to the size of the opening.
- Plaster or render around the frame that needs making good.
- A canopy or porch roof fitted at the same time.
Building regulations for a new front door
A replacement external door is a "controlled fitting" under the Building Regulations in England. You do not need to apply yourself if your installer is registered with a competent person scheme.
A registered installer can self-certify the work. GOV.UK says you should get a certificate within 8 weeks of completion. Keep it safe, because it can show up in solicitors' searches when you sell.
