The Short Answer
On our estimates, having an internal door hung costs about £70 to £200 per door in labour, or £120 to £350 supplied and fitted with a standard door and handles. Replacing every door in a typical house (say eight) is about £960 to £2,800.
Hanging a new door in an existing, sound frame is the quick job; new frames, non-standard sizes and fire doors cost more. An experienced joiner can fit several doors in a day.
Internal door prices
| Item | Typical cost |
|---|---|
| Hang a door, labour only | £70 to £200 |
| Door supplied and fitted, with handles and hinges | £120 to £350 |
| Handles and hinges, per door | £20 to £100 |
| Carpenter, per day | £250 to £320 |
Choosing the door
JELD-WEN, the door maker, sets out the options and their typical prices:
- Hollow core doors are the budget option, from about £30, and lightweight.
- Solid core doors are more durable and insulating, from about £60.
- Fire doors range from about £50 to £300 or more.
It recommends 3 hinges per door for stability and durability, and puts fitting labour at about £70 a door on average, plus a bit more to take the old door off.
Its other price points: glazing adds about 30 to 40% to many door styles; pre-finished doors (factory painted or stained) cost more than unfinished ones you paint yourself; and doors bought in bundles are often cheaper than buying them one by one. If you're doing the whole house, I'd buy unfinished doors in a bundle and have them painted with the rest of the decorating.
What's included, and what's extra
A fitting price usually covers trimming the new door to fit the existing frame (within reason) and minor adjustments to the frame. These are extra:
- repairing existing door frames;
- replacing or altering frames;
- fire door certification or specialist compliance work.
Quotes often assume standard-sized doors and frames in good condition, so I'd send photos of any odd-sized or tired frames before you get a price. JELD-WEN gives the same advice: frames that aren't square mean the new doors need trimming, so tell the joiner up front.
When you need fire doors
In England, when a loft conversion creates a storey more than 4.5m above the ground, Approved Document B asks for fire-resisting doors (at least E 20) on the escape route, upgrading existing doors where necessary. Fire doors cost more, and I'd use a carpenter who's fitted them before. See loft conversion fire safety.
