Building Performance Diagnostics in Woking

Woking is a Surrey commuter town of inter-war and post-war semis, larger detached homes and new-build apartments near the centre. This mix of stock means varied performance issues, all of which we diagnose by measurement and can remediate.

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 Woking.

Local building stock · Woking

The buildings of Woking, and how they perform.

Woking's housing is predominantly cavity-walled from the 1930s onward, with larger detached homes and a growing number of airtight, mechanically-ventilated new-build flats. Cavity and loft condition varies, while the new flats raise overheating and ventilation questions.

Typical properties in Woking
  • 1930s cavity-wall semis & detached houses
  • Larger detached commuter homes
  • Post-war suburban housing
  • New-build apartment developments
  • Extended and loft-converted family homes

Thermal Imaging Surveys in Woking

In Woking, thermal imaging checks cavity and loft insulation and new-build thermal bridges.

  • 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 Woking

We measure to separate condensation from genuine damp across Woking's mixed stock.

  • 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 Woking

Cavity condition, loft insulation and glazing lead loss in the houses; overheating leads the new flats.

  • 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 Woking

Blower door testing quantifies draughts in houses; new flats need ventilation commissioning.

  • 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 can deliver fabric-first upgrades on houses or re-commission ventilation in flats, 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
