Building Performance Diagnostics in Hertford
Hertford is a historic county-town of timber-framed and Georgian buildings, Victorian terraces and surrounding suburbs. We cover both heritage-safe retrofit for the period stock and fabric-first upgrades for the newer homes, always led 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 Hertford.

The buildings of Hertford, and how they perform.
Hertford's centre holds solid-wall and timber-framed period homes, often conservation-protected, with Victorian terraces and cavity-walled suburbs beyond. The right approach varies from heritage-aware internal insulation to cavity and loft upgrades.
- Timber-framed and Georgian period homes
- Victorian & Edwardian terraces
- Conservation-area properties
- Inter-war and post-war suburban semis
- Period houses converted into flats
Thermal Imaging Surveys in Hertford
In Hertford, thermal imaging spans heritage solid and timber-framed walls and suburban cavity checks.
- 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 Hertford
We measure to separate condensation from genuine damp across Hertford's period and suburban stock.
- 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 Hertford
Solid walls lead loss in the centre; cavity and loft condition lead it in the suburbs.
- 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 Hertford
Blower door testing locates leakage in period homes and quantifies it in suburban semis.
- 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 deliver heritage-safe insulation or fabric-first upgrades, then verify the result.
- 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
