Answer a handful of questions about what you have spotted at your property. The result gives a rough read on how likely the movement has a structural cause. Bear in mind this is a guide only: a physical investigation is what establishes the facts.

Could it be subsidence?

Have you noticed diagonal cracks wider than a 10p coin (about 3mm), often near doors, windows or corners?
Do the same cracks appear both inside and outside, or in the same place on different floors?
Have doors or windows started sticking, or do gaps show around the frames?
Is there a large tree close to the house, or has the area had a very dry spell lately?
Has the cracking appeared or widened in the last year?

An initial indication only; a specialist who visits the property will confirm what is actually present. Request an assessment for a written finding.

What each level means

  1. Low likelihood The signs you have described are minor and tend to have a non-structural explanation, such as seasonal thermal movement or drying shrinkage in plaster. Keep a dated note and watch for any change.
  2. Possible The combination of signs you have described is enough to merit a proper inspection. A structural specialist can establish whether the movement has a structural cause and advise on any action required.
  3. Worth investigating The pattern you have described is consistent with ground movement below the building. Arranging an assessment promptly gives you the clearest picture and tends to keep any repair scope smaller.
  • Seasonal movement: Cracks that open in summer and close in winter, particularly around window frames, are usually caused by thermal movement in the building fabric rather than ground instability.
  • Plaster shrinkage: Shallow crazing across plaster or render is typically drying shrinkage and carries no structural significance.
  • Old settlement: Settlement that occurred years ago and has shown no change since is not the same as active movement requiring investigation.
