Homes we inspect in Southall
Southall has Victorian and Edwardian terraces near the Broadway and the station, and large areas of interwar terraced and semi-detached houses. Rear extensions, loft conversions and garden outbuildings are common, often built in stages over several years.
When a house has been altered by different builders at different times, it is not always clear how the loads reach the ground. We trace that through the building before designing anything new.
Common structural issues in Southall
- Cracking where successive rear extensions were built onto each other.
- Loft conversions with steelwork or floors that need checking.
- Garden outbuildings and their foundations.
- Leaking drains softening the ground under part of a house.
- Removed walls and chimney breasts without adequate support.
Ground conditions
Much of Southall sits on river terrace gravels with brickearth on top, over London Clay. Brickearth can soften and lose strength when it gets wet, so leaking drains and poor surface drainage are worth checking when cracks appear.
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 Southall?
No. Our office is at Gable House, 18–24 Turnham Green Terrace, Chiswick, W4 1QP, and our engineers travel to Southall for inspections and site visits.
Can you check an extension built by a previous owner?
Yes. We inspect what can be seen, look for signs of movement and explain whether the work appears adequate. If there is no Building Control completion certificate, we can advise on what regularisation would involve.
