Building Performance Diagnostics in Hackney
Hackney's housing is overwhelmingly solid-wall and period — Georgian and Victorian terraces, De Beauvoir and Clapton conservation streets, mansion-flat conversions and the warehouse conversions of Hackney Wick. These buildings reward a building-physics-led approach, because the wrong insulation detail can create more damp than it cures.
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 Hackney.

The buildings of Hackney, and how they perform.
Most Hackney homes were built before cavity walls, so there is nothing to fill — heat is lost straight through 215mm of brick. Conservation-area and Listed constraints often rule out external insulation, pushing owners toward internal wall insulation, which carries real interstitial-condensation and mould risk unless the build-up is properly modelled.
- Georgian & early-Victorian terraces (conservation areas)
- Victorian terraces converted into flats
- Edwardian mansion blocks
- Hackney Wick warehouse & industrial conversions
- Ex-council estates and infill blocks
Thermal Imaging Surveys in Hackney
In Hackney's solid-wall stock, thermal imaging reveals exactly where heat escapes and where surfaces are cold enough to risk condensation — essential before committing to 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 Hackney
We see a great deal of misdiagnosed damp in Hackney. Surface temperature, relative humidity and dew-point readings separate condensation and mould from genuine penetrating or rising damp.
- 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 Hackney
With no cavity to fill, Hackney's heat-loss budget is dominated by solid walls, sash windows and uninsulated floors — so the retrofit order of operations matters.
- 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 Hackney
Period conversions in Hackney leak through floor voids, party walls and ex-chimney flues; blower door testing and smoke tracing locate the paths before sealing.
- 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 internal insulation is the only option, we model the build-up for condensation risk first — then we can install it and verify the outcome.
- 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
