The report mentions a cantilevered stone stair next to the soffit. Has a crack at the wall embedment been tested, or only named?
A crack at the wall embedment of a cantilevered stone stair has been named, not tested. The report places that stair next to the soffit and notes the crack where the stone goes into the wall. A home survey does not load the tread, open the masonry, or decide whether the crack is old, moving, or only a joint. Historic England explains that listing covers the whole building, stair included. The survey does not grant listed building consent. The sentence is an observation. It has not cleared the embedment and it has not specified a repair.

What is the fuller explanation?
A cantilevered stone stair is held where each tread is built into the wall, so a crack at that embedment is about the support, not a chip on the soffit face. The soffit is only the underside the surveyor could see. Looking up at a line in the stone does not show how deep the crack runs, or whether a tread has dropped. The visit recorded a visible crack beside a named form of stair. It did not open finishes, and it did not decide that the stone is failing.
Ask the solicitor to set the crack beside the list entry. Historic England explains that listing covers the whole building, so this stair is not a loose fitting the report can release. The survey does not grant consent, and it has not approved a repair method. If you need to know whether the embedment should be opened, instruct a structural engineer used to listed stone stairs. A firm step on the day is not that inspection. Leave the stone as found until the engineer has reported.
What should you ask your surveyor?
- Was the crack seen only from the soffit, or from the wall face as well?
- Did any tread look displaced, or was the note only a line in the stone?
- Which parts of the embedment were hidden by plaster or by the soffit finish?
What are the typical next steps?
- Show the solicitor the stair note beside the list entry.
- Instruct a conservation-aware structural engineer to see the embedment.
- Leave the stone untouched until that engineer has reported.
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
Does a firm tread clear the crack in the wall?
A firm tread on the day is not a load test of the embedment. The survey did not open the masonry and did not decide whether the crack is old or moving. Historic England explains that listing covers the whole building, and the survey does not grant consent. The step can feel steady while the support in the wall is still unknown.
Is the soffit a separate structure from the stair?
The soffit here is the underside of the stair that could be seen, not a second structure with its own verdict. A crack noted next to it is still the crack at the embedment. The survey has not tested that support. Historic England explains that listing covers the whole building, so the soffit is not a piece the inspection can leave off the list.
