Building Performance Diagnostics in Guildford
Guildford is a historic Surrey town of period and Georgian buildings, Victorian houses, larger detached homes and surrounding suburbs set among the hills. We cover heritage-safe retrofit and fabric-first upgrades alike, 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 Guildford.

The buildings of Guildford, and how they perform.
Guildford's centre holds solid-wall and timber-framed period homes, often conservation-protected, with Victorian houses and cavity-walled suburban and detached homes beyond. The right strategy ranges from heritage-aware internal insulation to cavity and loft upgrades and heat pump readiness.
- Historic and timber-framed period homes
- Georgian & Victorian houses
- Larger detached homes in the hills
- Inter-war and post-war suburban semis
- Period houses converted into flats
Thermal Imaging Surveys in Guildford
In Guildford, thermal imaging spans heritage solid and timber-framed walls, suburban cavity checks and larger-home surveys.
- 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 Guildford
We measure to separate condensation from genuine damp across Guildford'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 Guildford
Solid walls lead loss in the centre; cavity, loft and glazing lead it in the suburbs and detached homes.
- 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 Guildford
Blower door testing locates leakage in period and large 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, heat-pump-ready 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
