Building Performance Diagnostics in Mile End

Mile End mixes Victorian terraces, post-war council blocks and a large rented sector around Queen Mary University. For landlords and homeowners alike, the recurring issues are condensation, ventilation and cold solid walls — all of which we investigate by measurement and can remediate.

One company, the whole process

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 Mile End.

Local building stock · Mile End

The buildings of Mile End, and how they perform.

The terraces are solid-wall with suspended floors; the estates are concrete-framed with thermal-bridge cold bands. A high proportion of homes are let, often as HMOs, where occupancy density and closed-up ventilation drive humidity and mould far harder than the fabric alone would suggest.

Typical properties in Mile End
  • Victorian solid-wall terraces
  • Post-war council & ex-council blocks (concrete frame)
  • Houses in multiple occupation (HMO lets)
  • Student and young-professional rentals
  • Modern infill apartment blocks

Thermal Imaging Surveys in Mile End

In Mile End, thermal imaging quickly shows whether mould is driven by cold surfaces, missing insulation or simply inadequate 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 Mile End

For Mile End landlords we provide measured condensation and mould investigations that stand up to tenant disputes and inform a real fix.

  • 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 Mile End

Solid walls, floors and lofts lead heat loss in the terraces; floor-slab thermal bridges lead it in the estate flats.

  • 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 Mile End

Blower door testing is useful across Mile End's converted and let stock to quantify draughts and uncontrolled loss.

  • 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 effective extract or MVHR, insulate cold surfaces and verify that humidity and comfort actually improve.

  • 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
What we see locally

Common building performance problems in Mile End.

Black mould in shared and let properties with high occupancy and poor ventilation
Condensation on cold concrete-block corners in estate flats
Tenants blocking trickle vents and extract fans, raising humidity
Cold, hard-to-heat solid-wall bedrooms
Heat loss through uninsulated suspended floors and lofts
Inadequate or broken bathroom and kitchen extraction
High CO₂ and stale air in sealed-up rented rooms
