Subsidence, settlement and heave
The floor slopes towards the party wall and the doors still latch. Has the survey measured whether that slope is still moving?
No. The survey has not measured whether the slope is still moving. The floor slopes towards the party wall, and the doors still latch, which is a shape and a fact about the doors on the day. One visit cannot show a rate. The survey has recorded the slope and that the doors close. It has not monitored the floor, repeated a level, or decided that the slope is live or historic. Latching means the leaves still meet the stops. It is not a measurement of ongoing movement.

What is the fuller explanation?
Old houses often have floors that run to one side because the joists were undersized, the sleeper walls settled once, or the party wall is the low side of an original build. Doors that still latch tell you the frames are not currently jammed hard. They do not tell you the fall was the same ten years ago. A movement question needs two readings with time between them.
Ask the surveyor whether any level was taken, and if not, do not invent a fall for the lender. Tell the solicitor the doors latch and the floor slopes to the party wall, and that movement of that slope was not measured. If someone wants to know whether it is still moving, that is a later set of levels, not a second reading of this paragraph. An insurer should not be told the floor is on the move because it is not flat.
What should you ask your surveyor?
- Did you record a slope towards the party wall without a repeat level?
- Do the doors latch, and is that only a comment on the day?
- Have you measured any ongoing movement of this floor?
What are the typical next steps?
- Read the slope as a shape, and the latching as today's doors.
- Do not treat either as a measurement of ongoing movement.
- Take later levels only if you truly need to know whether it is moving.
Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.
Also asked about this
If a marble rolls to the party wall, is the floor still moving?
No. A roll shows the direction of the slope the survey already described. It does not show change over time. The inspection has not measured whether that slope is still moving, and a marble is not that measurement. Nothing in this visit settles the sloping floor beyond the lines already set out.
Does a door that latches slowly mean the frame is shifting?
Not on its own. A slow latch can be paint, a rising butt or the way the leaf hangs. The survey noted that the doors still latch. It did not measure movement in the frame or in the floor. That is as far as the recorded facts about the sloping floor can be taken.
