Homes we inspect in Twickenham
St Margarets and Strawberry Hill have Victorian and Edwardian terraces and villas, many with loft conversions and side-return extensions. Along the river, around Twickenham Embankment and Eel Pie Island, there are older houses, and Whitton and the streets towards the A316 have interwar semis and terraces.
Cracks around windows are one of the most common things we are asked to look at here. Often the cause is the lintel above the opening rather than the foundations, and the repair is very different.
Common structural issues in Twickenham
- Cracks around windows and bays, often from lintels rather than foundations.
- Movement where side-return and rear extensions join the original house.
- Roof spread in loft conversions.
- Cracks linked to trees near interwar houses.
- Riverside properties where drainage and flood risk need looking at.
Ground conditions
Twickenham is mostly on river terrace gravels over London Clay, with alluvium near the Thames and the River Crane. On gravels, leaking drains are a common cause of local movement, while trees matter more where clay is close to the surface.
We check the British Geological Survey records for every address we inspect, because ground conditions can change from one street to the next.

Common questions
Do you have an office in Twickenham?
No. Our office is at Gable House, 18–24 Turnham Green Terrace, Chiswick, W4 1QP, and our engineers travel to Twickenham for inspections and site visits.
Is the crack above my window a structural problem?
Often it is a lintel issue rather than movement of the foundations: a failed or missing lintel, or a timber lintel that has rotted. The shape and position of the crack usually tells an engineer which, and the repair is very different, so it is worth having it checked.
