Building Performance Diagnostics in Tunbridge Wells

Royal Tunbridge Wells is a heritage spa town of elegant Georgian and Victorian homes, conservation areas and Listed buildings. With substantial heat-loss budgets and strict constraints, careful, building-physics-led retrofit advice is essential here.

One company, the whole process

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 Tunbridge Wells.

Local building stock · Tunbridge Wells

The buildings of Tunbridge Wells, and how they perform.

Tunbridge Wells's housing is largely solid-wall period stock — including stucco and tile-hung elevations characteristic of the area — much of it conservation-protected or Listed. External insulation is rarely permitted, making internal insulation, secondary glazing and airtightness the realistic levers.

Typical properties in Tunbridge Wells
  • Georgian & Victorian spa-town homes
  • Tile-hung and stucco period properties
  • Listed and conservation-area buildings
  • Period houses converted into flats
  • Larger detached period homes

Thermal Imaging Surveys in Tunbridge Wells

In Tunbridge Wells, thermal imaging shows where heritage solid, stucco and tile-hung walls can safely take internal insulation.

  • 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 Tunbridge Wells

We give Tunbridge Wells homes an accurate condensation-versus-damp diagnosis from measured data.

  • 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 Tunbridge Wells

Solid walls, single glazing and large roofs lead the substantial heat-loss budgets typical of the area.

  • 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 Tunbridge Wells

Blower door testing locates the sash-box, floor and chimney leakage typical of period spa-town homes.

  • 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 modelled internal insulation, secondary glazing and ventilation, and verify the works.

  • 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
What we see locally

Common building performance problems in Tunbridge Wells.

Heritage and Listed constraints ruling out external insulation
Cold solid, stucco and tile-hung walls prone to condensation
Condensation on original sash and casement windows
High heating demand across tall period rooms
Thermal bridging at bays, extensions and roofs
Damp at solid-wall ground level misread as rising damp
Draughts through sash boxes, floors and chimneys
