Building Performance Diagnostics in Wimbledon

Wimbledon ranges from the conservation streets and large period homes of Wimbledon Village to ordinary Victorian terraces and suburban semis. We cover both the heritage retrofit questions and the fabric-first, heat-pump-readiness conversations of the suburban stock.

One company, the whole process

Investigation only, remedial works, or a complete retrofit — your choice.

RetrofitIQ is not only a diagnostics company. We take projects from first investigation through to verified improvement — and you decide how far we go. Engage us for an investigation on its own, for an investigation plus targeted remedial works, or for a complete building-performance and retrofit project in Wimbledon.

Local building stock · Wimbledon

The buildings of Wimbledon, and how they perform.

Wimbledon Village and the older streets are solid-wall period homes with large heat-loss budgets and conservation controls, while the surrounding suburbs are cavity-walled inter-war semis. The right approach differs sharply between the two, so we always measure first.

Typical properties in Wimbledon
  • Large Victorian & Edwardian period houses
  • Wimbledon Village conservation homes
  • Bay-fronted period terraces & semis
  • 1930s cavity-wall suburban semis
  • Period houses converted into flats

Thermal Imaging Surveys in Wimbledon

In Wimbledon, thermal imaging surveys both heritage solid walls and the cavity/loft condition of suburban semis.

  • Mapping heat loss through walls, roofs and floors
  • Locating missing, slumped or incomplete insulation
  • Identifying thermal bridging and cold spots
  • Highlighting surfaces at risk of condensation
  • Revealing hidden defects behind finishes

Damp, Condensation & Mould Investigations in Wimbledon

We confirm whether Wimbledon damp is cold-surface condensation or genuine damp using measured readings.

  • Separating condensation from penetrating and rising damp
  • Finding mould behind wardrobes, furniture and in cold corners
  • Measuring relative humidity, surface temperature and dew point
  • Assessing ventilation provision and moisture sources
  • Combining thermal imaging with a building-physics review

Heat Loss & Energy Efficiency Surveys in Wimbledon

Solid walls and bays lead loss in the period homes; cavity and loft condition lead it in the semis.

  • Pinpointing where heat escapes — walls, floors, roofs, windows and doors
  • Setting fabric-first retrofit priorities in the right order
  • Quantifying the impact of each potential improvement
  • Assessing heat pump readiness where relevant
  • Producing a clear, costed improvement plan

Blower Door Testing & Airtightness in Wimbledon

Blower door testing locates draughts in large period homes and quantifies leakage in suburban semis.

  • Measuring air leakage and uncontrolled heat loss (ACH₅₀)
  • Locating draughts with smoke tracing
  • Identifying leakage paths through floors, lofts and services
  • Guiding targeted airtightness improvements
  • Verifying performance before and after retrofit works

Retrofit & Building Physics Advice

We deliver heritage-safe retrofit on period homes or fabric-first heat-pump-readiness upgrades on semis, then verify.

  • A fabric-first, Passive House-informed approach
  • Retrofit advice aligned with PAS 2035 principles
  • Internal and external wall insulation risk assessment
  • Thermal-bridge reduction and condensation-risk modelling
  • A coherent ventilation strategy to protect health and fabric
