What we find in Winchester
Our approach here is diagnostic and conservative. We would rather remove a previous inappropriate repair than add a new layer on top of it.
The centre and Kingsgate area hold Georgian and earlier brick, flint and timber frame with lime finishes. St Cross and Hyde are largely Victorian. Weeke, Badger Farm and Stanmore are twentieth-century cavity construction with condensation-dominated problems.

Four things that go wrong in Winchester
Not a generic list. These are the defects our surveyors record most often at this postcode.
- 01
Flint wall moisture behaviour
Flint and lime rubble walls hold and move water very differently from brick and are easily damaged by cement repair.
- 02
Chalk block substrates
Highly absorbent chalk blockwork behind render needs careful, breathable specification.
- 03
Basement and lower ground rooms
Sloping topography means many central properties have below-ground rooms needing waterproofing design.
- 04
Condensation in modern estates
Tighter later housing with undersized extract shows the familiar bedroom mould pattern.
A large share of our Winchester surveys are second opinions, commissioned after a homeowner received an injection quotation that did not match the building.
