Thermographic Survey in Trowbridge

Trowbridge's housing stock has a broad spread of forms, and that affects how heat moves through each home. The town's 21.0% detached homes, 34.2% semi-detached homes, 27.6% terraced homes and 16.6% flats include everything from older fabric in the Town Centre Conservation Area to post-1980 homes on schemes like Highfield Gardens and Platinum Place. Older houses in the centre often rely on local stone or brick with solid walls, while mid-century homes tend to use cavity wall construction. Those differences change the thermal picture, so a survey that works on a 2010 house on Elizabeth Way will not read the same as a stone terrace near St Stephen's Place.

Construction method matters as much as age. Pre-1919 homes in the older streets often use solid wall construction with timber elements and slate or clay tile roofs, which makes insulation improvements harder to judge from the outside alone. Homes built between 1919 and 1980 usually shift to brick cavity walls and pitched roofs with concrete tiles, while post-1980 homes and new builds use modern brick-and-block cavity wall systems, uPVC windows and current insulation standards. Those newer homes can still leak heat at junctions, window reveals and loft access points, especially on fast-growing schemes such as Ashton Park, where the first phase by Persimmon Homes will deliver 161 homes.

Ground conditions also matter in Trowbridge. The town sits on Oxford Clay Formation, Kellaways Formation and Cornbrash Formation, with alluvium and river terrace deposits in places, so shrink-swell risk can influence cracks and moisture movement in some streets. Add the flood risk around the River Biss and the patchwork becomes more complex, because colder surfaces and damp readings can be linked to water ingress rather than insulation alone. Our thermal imaging specialists read those patterns in context, then explain what they mean for comfort, running costs and future maintenance. That is why local homes with mixed ages, mixed materials and mixed ground conditions benefit from infrared analysis.

Thermal images use a colour scale, usually with colder surfaces shown in blue and warmer surfaces moving through green, yellow, red and white. A blue patch on a ceiling in a Trowbridge terrace can indicate heat loss through poor loft insulation, while a brighter line at a wall junction may point to cold bridging. We explain the image in relation to the property, not as a stand-alone picture. That context matters in a town with stone houses near the centre and newer brick homes on the edge of BA14.

Not every hot or cold spot means a defect. Sun on a south-facing wall in Elizabeth Way, a reflective surface near a window, or a recently used radiator can all change the reading, which is why our surveyors check timings, weather and room conditions before we make a diagnosis. We also compare internal and external scans, so a wet area caused by moisture ingress near the River Biss reads differently from a wall that simply has poor insulation. The report explains those differences in straightforward language, with each image annotated so you can see exactly why a room is losing heat.

Clear interpretation turns raw data into action. If a loft hatch is leaking warm air, we show the point of failure and explain the fix. If a section of wall in St Stephen's Place is colder because of a missing cavity fill or a bridging issue at the floor edge, we point that out too. That approach helps homeowners decide which repairs will cut waste first, and which issues can wait until other works are planned.

A thermal imaging survey in Trowbridge starts from £300, which gives you a practical route into spotting heat loss before repair costs climb. The fee covers external and internal infrared scanning, image analysis and an annotated report that explains each finding in plain English. For a home in BA14 7JP, BA14 7LQ or a terrace close to the Town Centre Conservation Area, the value lies in seeing where energy is escaping rather than guessing at the cause. Larger or more complex homes can take longer to scan, which is why we confirm the scope before booking.

Accuracy improves when the building and the weather cooperate. We aim for October to March, keep the heating on for at least 2 hours before arrival and look for a minimum 10C difference between inside and outside. That gives sharper contrast on roofs, walls and windows, especially on homes with mixed materials such as local stone, brick and modern blockwork. If a house near the River Biss or a new build on West Ashton Road has recent solar gain on the external walls, we may adjust the timing so the images stay reliable.

The report usually follows after the survey has been reviewed and annotated, so you are not left interpreting the raw pictures alone. Our surveyors show which defects are urgent, which ones affect comfort now and which ones can wait until other works are planned. For many Trowbridge owners, that makes the survey a sensible first step before loft upgrades, window replacement or a wider energy-efficiency programme. It is a direct way to understand where money is being lost through the fabric of the home.
