Building Performance Diagnostics in Chelsea
Chelsea is a heritage SW3 enclave of Georgian and Victorian townhouses, red-brick mansion blocks and Listed period homes, many extensively refurbished with basements. As in neighbouring Kensington, every measure must respect protected fabric and be condensation-safe.
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 Chelsea.

- Soundproofing & acoustic upgrades
- General building-fabric improvements
The buildings of Chelsea, and how they perform.
Chelsea's homes are high-value solid-wall and brick period properties, frequently Listed, with deep basement conversions and high-specification fit-outs. Heritage status rules out external insulation, so modelled internal insulation, airtightness, glazing and basement detailing are the practical levers.
- Georgian & Victorian townhouses
- Red-brick mansion blocks
- Listed and conservation-area period homes
- Deep basement conversions
- High-specification refurbishments
Thermal Imaging Surveys in Chelsea
In Chelsea, thermal imaging surveys solid walls and complex basements to locate heat loss and condensation risk without harming heritage fabric.
- 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 Chelsea
We measure to distinguish condensation and ground moisture from genuine defects in Chelsea's basements and rooms.
- 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 Chelsea
Tall solid walls, sash windows and large volumes lead Chelsea's substantial heat demand.
- 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 Chelsea
Blower door testing locates leakage in large period homes and basement conversions.
- 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
Where heritage permits, we specify and deliver modelled internal insulation, glazing and ventilation, then verify.
- 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
