Building Performance Diagnostics in East Ham
East Ham is one of the most densely populated parts of London, built largely of Edwardian solid-wall terraces. High occupancy combined with pre-cavity construction makes condensation, mould and ventilation the defining issues — and we tackle them with measurement, not guesswork.
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 East Ham.

The buildings of East Ham, and how they perform.
The standard E6 house is a modest Edwardian terrace with 9-inch solid walls, a suspended timber floor and limited mechanical ventilation. Many are now in multiple occupation; the combination of moisture-generating activity and closed-up ventilation routinely pushes humidity past the point where mould forms on cold surfaces.
- Edwardian solid-wall terraces
- Houses in multiple occupation (HMO lets)
- Houses subdivided into flats
- Bay-fronted terraces with rear additions
- Smaller inter-war housing on the edges
Thermal Imaging Surveys in East Ham
In East Ham, thermal imaging distinguishes genuinely cold, under-insulated surfaces from rooms that simply need better ventilation.
- 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 East Ham
Our measured condensation and mould investigations give East Ham landlords and owners a defensible diagnosis and an effective plan.
- 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 East Ham
Solid walls, floors and lofts dominate heat loss across East Ham's Edwardian 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 East Ham
Blower door testing quantifies draughts, while ventilation assessment addresses the humidity that drives mould.
- 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 install proper extract or MVHR, insulate cold surfaces and verify that humidity falls and mould does not return.
- 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
