Building Performance Diagnostics in Bromley

Bromley is leafy suburban South London — inter-war and post-war semis, larger detached homes and modern estates, with Victorian pockets near the town centre. Fabric-first upgrades and heat pump readiness are the recurring themes, backed by measured assessment.

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 Bromley.

Local building stock · Bromley

The buildings of Bromley, and how they perform.

The typical Bromley home is a cavity-walled semi or detached house from the 1930s onward, with loft-insulated pitched roofs and suspended or solid floors. Cavity insulation condition varies, and larger homes carry bigger heat-loss budgets — both quantified by thermal imaging and airtightness testing.

Typical properties in Bromley
  • 1930s cavity-wall semis & detached houses
  • Post-war suburban housing & estates
  • Larger detached family homes
  • Victorian terraces near the town centre
  • Modern estate houses & flats

Thermal Imaging Surveys in Bromley

In Bromley, thermal imaging checks cavity and loft insulation and finds the cold spots that would undermine a heat pump.

  • 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 Bromley

We confirm whether Bromley damp is condensation, a bridged cavity or a localised defect.

  • 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 Bromley

Cavity condition, loft insulation, glazing and floor losses lead the heat-loss picture and heat pump readiness.

  • 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 Bromley

Blower door testing quantifies background leakage that matters for comfort and low-temperature heating.

  • 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 a fabric-first upgrade to get a Bromley home heat-pump-ready, then verify it.

  • 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
