Most trades will not put a price on their website. We think that is unhelpful, so here is what a new internal door costs with Mendwell, what drives the price up or down, and why some quotes you get will be cheaper than ours.
The short answer
A new solid core internal door, supplied and fitted into your existing frame, costs around £205 to £225 all in.
That includes the door, new hinges, latch and lever handles, fitting, adjusting so it closes cleanly, and sanding every planed edge smooth so it is ready for decorating. The door comes white primed, ready for painting.
Taking the old door away is not included. We can do it if you would like, for a small extra charge agreed on the quote.
If you have several doors done on the same visit, each one is priced the same. There is no hidden call-out charge on top.
What is in that price
- The door itself. We fit a solid core door as standard, about £70 to £80 to buy.
- New hinges, latch and lever handles, about £20 to £35. That is a chrome lever handle on a round rose, the same set we fit as standard. A different handle, or matching something already in the house, changes the price and we cost it at the visit. We use three hinges on every door, not two, because a solid door is heavy and two hinges is why doors drop and catch.
- Fitting, £110 per door. That covers trimming the door to your opening, cutting the hinge and latch recesses, hanging it, fitting the handles and adjusting it until it shuts without rattling and stays where you leave it.
- Protecting the room and the route in, and cleaning up after.
What makes it cost more
The frame needs replacing too. If the existing door frame (the lining) is loose, split or out of square, a new door will never hang well in it. A new lining supplied and fitted is around £250 on a stud wall or £300 on a brick wall, including stripping out the old one. Hanging the door into a new frame is £139 rather than £110, because the hinge recesses have to be cut in both the door and the frame.
New architrave. A new frame usually means new architrave, the trim around the opening. That is £145 for the first face and £85 for the other side of the same opening, supplied and fitted. Filling and painting is a separate option.
A non-standard opening. Most openings take a standard 610, 686 or 762 mm door. If yours is within about 15 mm of one of those, we trim the door to fit and that adds £40.
If it is further off than that, trimming is not the answer, because timber can come off a door and cannot go back on. Two things change instead. The choice of door narrows, since not every style is made in every size. And the frame may need packing out, which means fixing timber inside it to bring the opening down to a standard size, set plumb so the door still closes evenly. Once it is painted you do not see it. Which of those applies comes down to the measurement and to whether the existing frame is sound, so an odd size opening is one we price after a visit rather than from a page.
Painting. The door comes primed, not painted. Painting is not in the price above. Plenty of customers do this themselves.
So a full job, new door, new frame and architrave both sides on a stud wall, comes to roughly £715 to £735 all in. On a brick wall, roughly £765 to £785.
Why some quotes will be cheaper than ours
The honest answer is usually the door.
A hollow core door costs £30 to £50 to buy and is quicker to hang. It is two thin skins over a cardboard lattice. It dents when something catches it, the hinge screws work loose because there is nothing solid for them to bite into, and when it is damaged it is replaced rather than repaired.
We do not fit hollow core doors, even if asked. That is a deliberate choice, not an upsell. The difference in price is small against fitting the same door twice.
If a quote is well under £150 for a door supplied and fitted, it is almost certainly a hollow door on two hinges. That may be fine for a cupboard. It is not what we would put on a bedroom or a bathroom.
What the national guides say
For comparison, the Checkatrade cost guide for 2026 puts replacing an internal door at £120 to £400, with an average of around £250. We sit a little under that average, with a heavier door.
Who this is not for
- Fire doors. A solid core door is not a fire door. If you need a fire door, for example between a garage and the house, or on a landing in a three-storey house, that is a different product with seals and certified fittings. We quote those separately and say so.
- Made to measure or oversized doors. These are priced individually.
- A door only, with your own frame repairs. If the frame is not sound we will tell you before we fit anything, not after.
Want a proper price?
We visit before we quote. A photo tells us the style of door, but not whether the frame is square or the opening is a standard size, and those are what decide the price. The visit takes about half an hour, and you get a fixed price in writing afterwards, so there are no surprises on the day.
