Building Performance Diagnostics in Chiswick
Chiswick is a riverside W4 neighbourhood of handsome Victorian and Edwardian terraces, including Bedford Park — England's first garden suburb, now Listed and conservation-protected. Heritage constraints make a careful, building-physics-led approach essential here.
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 Chiswick.

The buildings of Chiswick, and how they perform.
Chiswick's housing is overwhelmingly solid-wall period stock, much of it in conservation areas or Listed, where external insulation is not permitted. Internal insulation, secondary glazing and airtightness are the realistic levers, and each must be modelled to avoid condensation in the original fabric.
- Victorian & Edwardian terraces
- Listed Bedford Park garden-suburb homes
- Conservation-area period properties
- Period houses converted into flats
- Riverside mansion blocks
Thermal Imaging Surveys in Chiswick
In Chiswick, thermal imaging guides where heritage solid walls can safely take internal insulation.
- 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 Chiswick
We separate condensation from genuine damp in Chiswick's period homes using measured readings, not assumptions.
- 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 Chiswick
Solid walls, single glazing and uninsulated roofs lead heat loss across Chiswick's protected stock.
- 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 Chiswick
Blower door testing and smoke tracing locate the sash-box, floor and chimney leakage typical of W4 homes.
- 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
Where heritage allows, we specify vapour-open, modelled insulation and ventilation, and can deliver and verify the works.
- 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
