Building Performance Diagnostics in Dagenham
Dagenham contains a large part of the historic Becontree Estate, alongside non-traditional inter-war housing and post-war estates. These construction types each have characteristic performance issues, and we diagnose and remediate them with a building-physics-led approach.
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 Dagenham.

The buildings of Dagenham, and how they perform.
Becontree (built 1921–1935) is a cottage-estate of mostly solid-wall and some non-traditional houses with modest insulation and suspended floors. Pockets of concrete and steel-framed homes bring their own thermal-bridging and condensation risks, alongside later council housing.
- Becontree Estate cottage-style houses
- Non-traditional concrete / steel-framed homes
- Post-war council & ex-council housing
- Suspended-floor solid-wall homes
- Let properties and HMOs
Thermal Imaging Surveys in Dagenham
In Dagenham, thermal imaging is invaluable for non-traditional homes, where the right insulation strategy is not obvious from outside.
- 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 Dagenham
We measure to confirm whether Becontree and non-traditional homes are suffering condensation or genuine 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 Dagenham
Solid and non-traditional walls, lofts and floors lead heat loss across Dagenham's inter-war 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 Dagenham
Blower door testing quantifies the draughts common in older Becontree cottages.
- 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 loft and floor insulation to careful wall strategies on non-traditional homes, we specify, install and verify the works.
- 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
