Homes we inspect in Muswell Hill
Most of Muswell Hill was developed between the 1890s and the First World War, with Edwardian houses, purpose-built flats and shopping parades put up by a small number of developers. Many houses have since had loft conversions and rear extensions, and some have been divided into flats. Alexandra Palace and its park sit on the hill to the north east.
Because so many houses were built at the same time and in the same way, problems on one often show up on its neighbours too.
Common structural issues in Muswell Hill
- Seasonal movement on clay near street and garden trees.
- Movement on steep slopes and around garden retaining walls.
- Roof spread from loft conversions.
- Bay and front wall cracking in Edwardian houses.
- Heave where large trees have been removed.
Ground conditions
Muswell Hill is a ridge of London Clay, with steep streets falling away on several sides. On clay, trees and dry summers drive seasonal movement, and slopes can add to it.
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 Muswell Hill?
No. Our office is at Gable House, 18–24 Turnham Green Terrace, Chiswick, W4 1QP, and our engineers travel to Muswell Hill for inspections and site visits.
Is subsidence common in Muswell Hill?
Clay shrinkage near trees is a common cause of cracking in this part of North London, but most cracks are not subsidence. An inspection looks at the pattern of cracking, nearby trees, drains and the age of any alterations to identify the likely cause.
