Building Performance Diagnostics in Orpington
Orpington is leafy outer-London/Kent suburbia — inter-war and post-war semis, larger detached homes and modern estates. Fabric-first upgrades and heat pump readiness lead the conversation, backed by measured assessment.
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 Orpington.

The buildings of Orpington, and how they perform.
The typical Orpington home is a cavity-walled 1930s or post-war semi with a loft-insulated pitched roof and suspended or solid floor. Cavity insulation condition varies, and bay windows and extensions add thermal bridges that affect comfort and heat pump suitability.
- 1930s cavity-wall semis & detached houses
- Post-war suburban housing
- Larger detached family homes
- Modern estate houses & flats
- Extended and loft-converted homes
Thermal Imaging Surveys in Orpington
In Orpington, 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 Orpington
We confirm whether Orpington 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 Orpington
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 Orpington
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
