Homes we inspect in Hounslow
Near Hounslow town centre there are Victorian and Edwardian terraces, while much of Hounslow West, Lampton, Heston and Cranford is interwar terraced and semi-detached housing. Hip-to-gable loft conversions, rear extensions and garage conversions are very common.
A hip-to-gable conversion rebuilds part of the roof and adds a new gable wall, which changes how the roof loads reach the walls. We check the existing structure before designing new steelwork.
Common structural issues in Hounslow
- Cracking around hip-to-gable loft conversions and new gable walls.
- Garage conversions where a new wall or opening was formed.
- Movement at the junction of rear extensions and the original house.
- Leaking drains on gravel and brickearth.
- Bay window movement in interwar semis.
Ground conditions
Hounslow is largely on river terrace gravels, in places covered by brickearth, over London Clay. Clay shrinkage tends to be less of a factor here than across much of North London, so leaking drains and earlier alterations are often the first things we look at 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 Hounslow?
No. Our office is at Gable House, 18–24 Turnham Green Terrace, Chiswick, W4 1QP, and our engineers travel to Hounslow for inspections and site visits.
Do I need an engineer for a hip-to-gable loft conversion?
Yes. Building Control needs calculations for the new floor, any steel beams and the gable wall, and your builder needs the drawings to price and build it. If you share a party wall, you may also need to serve notice on your neighbour.
