Cracks are common in buildings, but not every crack indicates a structural problem. Small cracks can occur as materials dry, finishes age or buildings respond to seasonal changes. Other patterns may warrant closer assessment, particularly where cracking is new, changing, repeated or accompanied by other signs of movement. This guide explains what to note before arranging an inspection in South East London.
Start by recording the location and appearance. Note whether the crack is in plaster, brickwork or another material; whether it runs vertically, horizontally or diagonally; and whether it begins at a window, door or corner. Take clear photographs from a consistent distance and include a ruler or scale where practical. Record the date and repeat photographs periodically if you are monitoring a change. Avoid filling or decorating over a crack before its condition has been assessed if you are concerned that it is active.
Look for related symptoms, without assuming they share one cause. Doors or windows that have recently become difficult to operate, gaps at junctions, changes in floor level or visible distortion may provide useful context. Also make a note of recent building work, leaks, drainage problems, tree or vegetation changes, and any repairs already undertaken. These details can help the engineer decide what to examine.
A structural engineer’s inspection is useful when the cause is uncertain, the crack appears to be progressing, or a buyer, lender, insurer or property owner needs a professional assessment. The appropriate service depends on the extent of the concern. A specific structural inspection focuses on a defined issue; a general inspection considers a broader range of visible structural elements. The report should make clear what was and was not inspected.
Further investigation is not automatic. Depending on the evidence, an engineer may recommend monitoring over time, checking drainage, reviewing previous reports, or carrying out carefully planned opening-up or ground investigation. Such work should be specified for a reason; it is not possible to determine the need for underpinning or another major repair from a crack photograph alone.
Laytoe can discuss structural inspection requirements across the SE postcode area. When enquiring, provide the full address, the age and type of property if known, where the cracks are located, when they first appeared and whether they have changed. If there is sudden significant movement, falling material or an immediate safety concern, keep people away from the affected area and seek urgent professional assistance.
