Building Performance Diagnostics in Bow
Bow combines tight Victorian terraced streets, large post-war council estates and landmark conversions such as the Bow Quarter. Each has a distinct performance signature, so we measure before recommending — and can take a project from investigation through to insulation, airtightness and ventilation works.
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 Bow.

The buildings of Bow, and how they perform.
The terraces are solid-wall with suspended ground floors and back-additions that are notoriously cold. The estates bring system-built and concrete-panel construction with linear thermal bridges at floor slabs, while the Bow Quarter and similar conversions pair heavyweight industrial fabric with retrofitted glazing and services.
- Victorian solid-wall terraces with rear back-additions
- Post-war council blocks (system-built / concrete panel)
- Bow Quarter and other industrial conversions
- Houses subdivided into flats
- Recent infill new-build apartments
Thermal Imaging Surveys in Bow
In Bow we frequently thermal-image the main-house-to-back-addition junction, where cold bridging and damp cluster.
- 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 Bow
Bow's cold rear additions and concrete-panel corners are classic condensation hot-spots; we confirm with moisture and dew-point readings rather than assume.
- 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 Bow
Solid walls, cold back-additions and uninsulated floors lead Bow's heat-loss picture in the terraces; floor-slab thermal bridges lead it in the estates.
- 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 Bow
Suspended floors and subdivided flats make blower door testing valuable in Bow for finding hidden leakage between dwellings.
- 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 insulate and air-seal the cold back-addition, correct the thermal bridge, and re-test to prove the improvement.
- 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
