Building Performance Diagnostics in Ilford
Ilford is a largely suburban Redbridge district of Edwardian and inter-war housing, much of it cavity-walled. The performance questions here differ from inner East London: failed or incomplete cavity insulation, loft heat loss and condensation in converted and let homes. We measure first, then advise or remediate.
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 Ilford.

The buildings of Ilford, and how they perform.
Many Ilford houses date from the 1920s–30s and have early cavity walls — but cavity insulation may be missing, incomplete, slumped or wet, which thermal imaging can reveal. Larger Edwardian and Victorian houses near Ilford town centre are often subdivided into flats and HMOs, adding ventilation and condensation pressures.
- 1920s–30s cavity-wall semis & terraces
- Edwardian bay-fronted houses
- Larger houses converted into flats / HMOs
- Post-war and modern infill housing
- Mansion-style blocks near the town centre
Thermal Imaging Surveys in Ilford
In Ilford, thermal imaging is the quickest way to see whether a cavity wall is actually insulated — and whether that insulation has slumped or got wet.
- 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 Ilford
We diagnose whether Ilford damp is condensation, a bridged cavity or a genuine defect, using moisture and surface-temperature readings.
- 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 Ilford
Cavity-wall condition, loft insulation and glazing lead heat loss across Ilford's suburban 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 Ilford
Blower door testing quantifies draughts in older semis and helps prioritise sealing works.
- 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 advise on cavity remediation, top up loft insulation, improve ventilation and verify the improvement by re-testing.
- 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
