Hanging a door in a new-build is fairly predictable. The frame is square, the floor is level and the door comes in a standard size. Period properties are a different story. Hampshire has plenty of Victorian terraces, Edwardian semis and older cottages, and anyone who has tried to fit a new door in one knows that very little is as straightforward as it looks. Here is what makes the job harder, and how a carpenter deals with it.

Nothing Is Square or Level

After a hundred years or more, houses move. Timber lintels sag slightly, walls settle and floors slope as joists deflect. The result is door openings that are out of square, with heads that drop to one side and jambs that lean in or out. It is common to find an opening that is 10mm wider at the top than the bottom, or a floor that falls 15mm across the width of a doorway.

A standard door dropped into an opening like that will either bind on one side or leave an uneven gap that looks wrong straight away. The carpenter has to decide whether to adjust the frame, scribe the door to suit the opening, or do a bit of both. Getting the margins around the door even, usually around 2-3mm, takes careful planing and a lot of test fitting.

Non-Standard Sizes

Modern doors come in a handful of stock sizes. Older houses were built long before those sizes were settled, so openings are often a few centimetres taller, shorter or narrower than anything off the shelf. You then have a few options:

Cut down a larger stock door, keeping enough timber in the stiles and rails so it stays strong
Add a lining or packing to reduce the opening to suit a standard door
Have a door made to measure, which is often the best answer for tall Victorian openings
Restore and rehang the original door if it is still sound

There is a limit to how much you can take off a door. Most manufacturers state a maximum trim per edge, and going beyond it can weaken the joints or void the warranty. Engineered and veneered doors are usually less forgiving than solid timber here, which is worth knowing before you buy.

Old Frames and Linings

Original door linings in period homes are often softwood that has been painted many times over. Layers of old paint build up in the rebates and on the hinge side, so a new door will not sit flush until they are stripped back. You may also find old hinge recesses in the wrong place, filled holes from previous locks, and timber that has split around the screws.

A good carpenter will check the lining is solid before hanging anything. Loose linings can be refixed to the wall, split sections can be spliced in with new timber, and old hinge positions can be let in and filled properly so the new hinges have something firm to bite into. If the lining is too far gone, replacing it is usually quicker and neater than patching. Some of the same causes behind a sticking door apply here too, and our guide on why doors stick covers those in more detail.

Keeping the Character

In a period house, the door is part of the look of the room. Four-panel and six-panel doors, deep moulded architraves and traditional ironmongery all matter. Swapping them for flush modern doors can make a Victorian hallway feel oddly out of place. Where possible, we try to keep original doors and match new ones to the existing style, including panel layout and moulding profile.

Architraves are often the trickiest part. Older profiles are rarely available off the shelf, so matching them may mean having a short length machined to the original shape. If the house is listed or in a conservation area, it is worth checking what changes are allowed before any original joinery comes out.

Floors, Thresholds and Clearances

Period floors add their own problems. Original boards may have been covered with carpet, then laminate, then a new engineered floor, each one raising the level. Doors that cleared the floor years ago now catch on it. The bottom of the door may need trimming, but on a sloping floor the cut has to follow the fall so the gap looks even when the door is closed and still clears the floor when it swings open.

Thresholds between rooms also need thought, especially where two floor finishes meet at different heights. A neat threshold strip or a properly scribed door bottom makes the difference between a job that looks finished and one that looks botched.

Getting Doors Fitted Properly

Fitting doors in older homes takes patience, the right tools and a good eye for how the house has moved over time. Every job differs, and a door that takes an hour in a new-build can take half a day in a Victorian terrace once the frame, lining and floor have been sorted. That time is what gets you a door that closes cleanly, sits evenly in its frame and suits the character of the house.
