Building Performance Diagnostics in Acton
Acton mixes Victorian and Edwardian terraces, former industrial sites and a wave of new-build regeneration around the Crossrail/Elizabeth line corridor. The result is a broad spread of building types, each needing its own performance approach — all 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 Acton.

The buildings of Acton, and how they perform.
Older Acton streets are solid-wall terraces with suspended floors and rear additions, many converted to flats or let as HMOs. Newer development brings airtight apartments reliant on mechanical ventilation, where overheating and commissioning replace draughts as the main concern.

Thermal Imaging Surveys in Acton
In Acton, thermal imaging works across both solid-wall terraces and the thermal-bridge details of new-build 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 Acton
We measure to separate cold-surface condensation from genuine damp across Acton'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 Acton
Solid walls, floors and lofts 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 Acton
Blower door testing is valuable on Acton's older converted houses to quantify draughts and 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 in new-builds, then verify the result.
- 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
