Chimneys and parapets

What should you ask if a chimney breast has been removed in a downstairs room?

Ask what is holding up the breast that remains in the room above, or the stack on the roof, and whether any building-regulations paperwork exists for that support. A tidy alcove is not proof the load has a beam. A home survey often cannot see the support without opening up.

What is the fuller explanation?

Removing a breast and leaving the masonry above is a structural alteration. The surveyor may see a beam, a steel, or nothing but plaster. They will not pull the ceiling down on a standard inspection. If the support is hidden, the report should say it was not confirmed. Party-wall or neighbour issues can arise in a terrace if the stack is shared. The survey does not settle the legal side.

Your solicitor can ask for building-regulations approval and for any engineer’s calculation the seller has. Absence of papers does not prove the beam is missing, and a steel you can see is not proof it was designed for this load. If the rooms above show fresh cracks around the remaining breast, say so. Costs of exposing a bearing vary. Do not invent a price from the rating.

What should you ask your surveyor?

  • Could you see a beam or a steel, or only plaster where the breast was?
  • What remains above, and did those rooms show distress?
  • Are you recommending the support be confirmed before commitment, or only noting that you could not see it?

What are the typical next steps?

  1. Ask the seller for any approval or calculation, and give it to the surveyor if it arrives in time.
  2. Do not knock the plaster off before exchange to “just look”.
  3. If the stack is shared, tell your solicitor before anyone talks about removal.

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

Is a remaining breast upstairs safe by default?

No. It still has weight. The question is whether that weight has a proper bearing. The survey may not have seen it.

Does a steel RSJ mean the work was approved?

No. A steel can be installed without building-regulations approval. The paper and the steel are different facts. Ask the solicitor for the paper.
