Damp Proofing and Mould Specialists in Southampton
Southampton work is dominated by two building types: long Victorian terraced streets through Portswood, Bevois Valley, Shirley and St Denys, and post-war flatted stock across the city. The first brings solid-wall saturation and sub-floor decay; the second brings condensation.

What we find in Southampton
A significant share of our Southampton instructions come from landlords and managing agents, so our reports are written to stand up in a disrepair or compliance context as well as to guide the repair.
Terraced SO15–SO17 housing is typically 1880–1914, solid nine-inch brick, suspended timber ground floors and shared chimney stacks. Much of it now operates as student or shared accommodation, with occupancy levels well above what the original ventilation was designed for.
Four things that go wrong in Southampton
Not a generic list. These are the defects our surveyors record most often at this postcode.
- 01
Overcrowded ventilation in shared housing
HMOs and student lets generate far more moisture than intermittent bathroom extract can remove, producing widespread bedroom mould.
- 02
Solid nine-inch wall penetration
With no cavity, driven rain on an exposed gable crosses directly to internal plaster.
- 03
Shared chimney stack ingress
Long terraces with neglected stacks produce high-level damp on breasts in the rooms below.
- 04
Buried airbricks in rear yards
Concreted and raised rear yards seal sub-floor ventilation, leading to joist-end wet rot.
For landlord instructions we quantify the fabric contribution and the occupancy contribution separately, with logged humidity data where a dispute is likely.
