Building Performance Diagnostics in Gravesend
Gravesend is a riverside Kent town of Victorian terraces, post-war housing and a substantial rented sector. Coastal-estuary exposure, condensation and cold solid walls are the everyday issues, which we diagnose and remediate by measurement.
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 Gravesend.

The buildings of Gravesend, and how they perform.
Gravesend's older stock is solid-wall Victorian terracing, much of it converted or let, with post-war estates and homes exposed to estuary weather. Wind-driven rain, high occupancy and limited ventilation make damp and condensation especially common.
- Victorian solid-wall terraces
- Post-war council & ex-council housing
- Period houses converted into flats
- Riverside / estuary-facing homes
- Let properties and HMOs
Thermal Imaging Surveys in Gravesend
In Gravesend, thermal imaging helps distinguish wind-driven penetrating damp from condensation on exposed walls.
- 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 Gravesend
We measure surface temperature, humidity and moisture to separate estuary penetrating damp from condensation.
- 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 Gravesend
Solid walls, floors and lofts lead heat loss across Gravesend's riverside terraces.
- 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 Gravesend
Blower door testing quantifies draughts that estuary exposure makes especially costly.
- 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 address penetrating damp, insulate cold surfaces and improve 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
