Local property context

What matters when surveying in Finchley

Finchley houses are generally well built and less complicated than inner London terraces, but they sit on clay ground with many mature trees in gardens and streets. Clay shrinks as trees draw water from it in dry summers and swells again in wet winters, and that seasonal movement lies behind many of the cracks seen in north London suburbs.

A Level 2 often suits a 1930s semi or purpose-built flat in reasonable condition. A Level 3 is worth considering where the house has been heavily extended, where cracking is visible, or where you plan significant work.

Local knowledge for Finchley buyers

Interwar houses tend to have clay or concrete tile roofs, bay windows with their own small roofs, and rendered or pebbledashed walls. Roof coverings of this age may be nearing replacement. Many have cavity walls built with early metal wall ties, which can corrode; horizontal cracking along mortar joints is one of the signs the survey looks for.

Houses built before 2000 may contain asbestos in products such as textured ceiling coatings, floor tiles, flue pipes and garage roofs. A home survey is not an asbestos survey, but the report notes materials that look as though they could contain it so you can decide whether testing is needed.

Ground conditions vary across Finchley, with clay and gravel deposits over London Clay in places. The British Geological Survey’s GeoIndex shows the mapped geology for a given street. Barnet also has several conservation areas, including parts of Finchley, where external changes may need consent.

Condition themes to consider

These are prompts for inspection, not a prediction that a particular home has a defect.

  • Clay shrinkage subsidence near mature trees
  • Bay window movement
  • Original roof coverings near the end of their life
  • Corrosion of early metal wall ties
  • Possible asbestos in older fittings and outbuildings
  • Quality of loft conversions and extensions

Before exchange of contracts

  • Tell us about large trees near the house, including in neighbouring gardens and the street.
  • Ask the seller about any past subsidence claims, underpinning or monitoring.
  • Ask for approvals for loft conversions, extensions and any removed walls.
  • If the report suggests asbestos testing or a drain survey, arrange it before exchange.

Queens Park

Queens Park is where JBS Surveying is based. The name covers two different places: the late Victorian and Edwardian streets around the park itself on the Brent side, and the Queen’s Park Estate south of the Harrow Road in Westminster, a planned estate of small terraced cottages built by the Artizans’, Labourers’ and General Dwellings Company from the 1870s.

Kilburn

Kilburn grew up along the old Roman road now called Kilburn High Road, which forms the boundary between Brent and Camden. Behind the high road are streets of Victorian houses, many long since converted into flats, alongside mansion blocks, flats above shops and large post-war and later council estates.
