Building Performance Diagnostics in Forest Gate
Forest Gate is a densely terraced E7 neighbourhood of Victorian and Edwardian solid-wall houses, many extended, converted or let. Condensation, mould and cold rooms are the everyday complaints, and we provide the measured diagnosis — and remediation — that actually resolves them.
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 Forest Gate.

The buildings of Forest Gate, and how they perform.
The housing is almost entirely pre-cavity solid brick with suspended ground floors and rear back-additions. Rising house prices have driven extensive rear extensions, loft conversions and house-to-flat subdivisions, each adding new junctions where cold bridging and condensation can take hold.
- Victorian & Edwardian solid-wall terraces
- Rear-extended and loft-converted houses
- Houses subdivided into flats
- Landlord-let HMOs
- Bay-fronted family homes
Thermal Imaging Surveys in Forest Gate
Across Forest Gate, thermal imaging shows whether mould is driven by cold solid walls, missing insulation or ventilation faults.
- 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 Forest Gate
We separate condensation from penetrating and rising damp using surface temperature, humidity and dew-point readings — the only reliable way.
- 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 Forest Gate
Solid walls, cold back-additions and uninsulated floors and lofts lead Forest Gate's heat-loss picture.
- 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 Forest Gate
Blower door testing quantifies the draughts that make E7 terraces feel cold and expensive to heat.
- 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
From targeted ventilation to wall, floor and loft insulation, we can carry out the works and verify that the mould stays away.
- 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
