Building Performance Diagnostics in West Ham
West Ham sits between the dense terraces of Plaistow and the regeneration zones along the Lower Lea Valley. The result is a mix of solid-wall period housing and newer apartments, each needing a different building-performance approach — both of which we cover end to end.
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 West Ham.

The buildings of West Ham, and how they perform.
Older West Ham streets are solid-wall Victorian terraces with the familiar cold back-additions and suspended floors. Newer development around Stratford and the riverside brings airtight flats reliant on mechanical ventilation, where overheating and commissioning replace draughts as the main concern.
- Victorian solid-wall terraces (Plaistow, Upton)
- Houses with cold rear back-additions
- Regeneration-area new-build flats
- Ex-council and post-war housing
- Converted upper and lower flats
Thermal Imaging Surveys in West Ham
In West Ham, thermal imaging maps solid-wall heat loss in the terraces and checks thermal-bridge details in the newer flats.
- 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 West Ham
We measure to separate cold-surface condensation from genuine damp across West Ham's varied stock.
- 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 West Ham
Solid walls, back-additions and floors lead heat loss in the terraces; glazing and overheating dominate the new-builds.
- 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 West Ham
Blower door testing is valuable on West Ham's older converted houses to locate inter-floor leakage.
- 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 period homes, or re-commission ventilation and add solar control in new-builds, then 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
