Building Performance Diagnostics in Peckham
Peckham is a fast-changing SE15 neighbourhood of Victorian terraces, large council estates and period conversions, with a substantial rented sector. Condensation, mould and cold solid-wall homes dominate, and we tackle them with measurement and remediation.
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 Peckham.

The buildings of Peckham, and how they perform.
Peckham's terraces are solid-wall with suspended floors and rear additions, widely converted into flats and let as HMOs. Its estates bring concrete-framed blocks with thermal bridges; high occupancy and limited ventilation push humidity to mould-forming levels.

Thermal Imaging Surveys in Peckham
In Peckham, thermal imaging shows whether mould is driven by cold surfaces, missing insulation or poor 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 Peckham
Our measured condensation and mould investigations give Peckham landlords and owners a defensible diagnosis and 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 Peckham
Solid walls, floors and lofts lead loss in the terraces; floor-slab bridges lead it in the estates.
- 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 Peckham
Blower door testing quantifies draughts across Peckham's converted and let stock.
- 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 ventilation, insulate cold surfaces and verify that humidity and comfort 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
