East London Building Performance Diagnostics & Retrofit — E, IG, RM
From the converted Victorian terraces of Walthamstow and Leyton through the warehouse conversions of Hackney Wick and Bow to the new-build estates of Stratford and Canary Wharf — East London has one of the most varied building stocks in the capital. Our diagnostics-led approach matches the remedy to the actual construction, not a generic assumption.
Diagnostics-led building performance, delivered locally.
Every survey starts with measurement — FLIR thermal imaging, blower door testing, moisture mapping and surface temperature readings. The findings drive the spec, not the other way round.

- Blower Door / Airtightness Testing
- Damp, Moisture & Condensation Investigation

These are the recurring building-physics issues we diagnose across East London. Every project still starts with measured data — but knowing the typical patterns helps focus the investigation.
- ▪Solid-wall Victorian terraces in Stratford, Bethnal Green, Hackney, Leyton and Walthamstow with no cavity to fill
- ▪Warehouse conversions with single-glazed industrial windows and no perimeter thermal break
- ▪Council-block flats (Tower Hamlets, Newham) with uninsulated concrete soffits and party walls
- ▪Olympic-Park-era new-builds with documented airtightness drift and thermal-bridging issues
- ▪Suburban semis in Ilford / Romford with original cavity-fill that has slumped over decades
- ▪Bow and Hackney warehouse conversions with chronic mould on inside faces of single-skin brick walls
- ▪High-occupancy HMOs across Newham and Waltham Forest with persistent kitchen and bathroom condensation
- ▪North-facing master bedrooms in Olympic Park townhouses with documented surface-temperature drift
- ▪Council-block bathrooms with no working extract and persistent ceiling mould
- ▪Warehouse conversions with original cast-iron column-to-floor junctions left open
- ▪Loft hatches and roof-to-wall junctions in Victorian terraces (E5, E8, E10)
- ▪Service penetrations through external walls in 1960s council blocks
- ▪Front-door perimeters in conversion flats with no compression seal
- ▪Whole-house EnerPHit-style retrofit on Victorian terraces in E5, E8, E17
- ▪Airtightness-first remediation programme for warehouse conversion blocks
- ▪MVHR retrofit into Olympic Park townhouses to fix documented IAQ issues
- ▪Independent retrofit review for Tower Hamlets / Newham social-housing stock
- ▪Damp and condensation investigation programmes for Council and HMO landlords

Real completed Retrofit IQ investigations from East London and across Greater London — full diagnostic methodology, measurements taken, findings and outcomes.
Investigate → Diagnose → Design → Remediate → Verify
RetrofitIQ is not only a diagnostics company. We take projects in East London from first investigation through to verified improvement — and you decide how far we go. Engage us for an investigation on its own, an investigation plus targeted remedial works, or a complete building-performance and retrofit project.
A measured diagnosis — thermal imaging, blower door testing, moisture and building-physics analysis — with a clear, costed report you can act on however you choose.
We investigate, then carry out targeted remedial works — airtightness, insulation, ventilation or thermal-bridge corrections — and verify the result.
A full fabric-first, Passive House-informed retrofit from diagnosis through design, installation and verification — one accountable team, one point of responsibility.
